2 Less-Known Methods To Improve Soil Fertility

In part 1, I talked about how organic matter is the most important ingredient for many gardens, and how mulch and compost are two of my favorite ways of using it.

But there are two other ways of using organic matter. The first is in some ways the most powerful of all, and the second may play an important role in reversing climate change. Let’s get into them… Read More

If I Could Do Only One Task In My Garden…

There are dozens of strategies you can implement to have a more successful garden.

And what your garden needs may be very different from what my garden needs.

But there is one ingredient that, when used properly, is often going to have a tremendous impact on most gardens around the world. Read More

How To Get Rid Of Slugs And Snails In The Garden

Getting Rid Of SlugsNot all snails and slugs are pests, so if they’re not eating your plants, you don’t need to get rid of them in your organic garden.

Slugs and snails are closely related.

The main difference is that snails have a shell, while slugs don’t.

Most molluscs live in the water, but slugs and snails are the two that can live on land as well.

In fact, there’s your most important clue right there for how to get rid of slugs and snails in the garden – they like it wet. Read More

My 2 Strategies For Growing Nutritious, Organic Food

by Phil Nauta

Part 1. Nutrition

Pesticide spraying
This type of pesticide spraying still happens all around the world.

Updated Feb 25, 2017

Our world has issues.

Corruption, environmental degradation, poverty, world hunger – the list goes on and on.

In my view, one of the biggest problems is our food system.

It’s polluting our environment and polluting us, and it’s not providing us with the nutrition we need – and that includes organic food.

I’ve heard some of the brightest minds in organic agriculture – including Dr. Arden Andersen and Dr. Elaine Ingham – say that in some cases, we’ve lost over 60% of the nutrition in our food in less than 60 years.

60 percent!

When we don’t provide our bodies with proper nutrition, we don’t think as well, sleep as well or treat each other as well.

We’re less happy, and of course we’re more sick.

Our current food system is a huge problem, and it’s important to shed light on these issues, but I think it’s just as important to focus on solutions rather than spending too much time feeling down about it.

Food is life giving. It’s so diverse and beautiful. It’s part of our cultural and social bonding. It has healing abilities. There’s so much powerful opportunity in food.

My organic garden
My organic garden last summer – young pear tree in the foreground.

And fortunately, you can grow your own – in your backyard, on your balcony or in a community/allotment garden.

It will take a bit of work and there will be a few mistakes along the way because there are a lot of things you need to learn, but you can learn them.

To me, one of the most important ways of improving our food system and our own health is to grow our own food, and not just any food, but highly nutritious, organic food.

That’s the part most gardening experts get wrong, and what I’m going to focus on today.

Doing this means more than just using compost, more than just switching to organic fertilizers and pesticides, and more than square food gardening or any of these other trendy methods being touted in gardening books.

To do it, you need to know a little about chemistry and biology, which is the subject of the first lesson in this 3 part series…

Chemistry

Chemistry basically refers to the periodic table of elements and how those elements interact.

Seaweed
Less than 20 elements are currently considered ‘essential’ for plant growth, although some of us believe many of them are probably important for optimal plant health.

There are over 100 of them – hydrogen, nitrogen, calcium and so on.

How much of each element you have in your soil is based on the underlying rock material that’s native to your area or was brought in by glaciers, waterways, volcanoes or wind.

Rain can also have a big impact by moving those elements somewhere else – downhill or down into the subsoil.

Use of chemical fertilizers and pesticides also changes the soil chemistry.

If you weren’t too concerned about which plants grew in your yard, you wouldn’t have to do anything to change the soil chemistry because odds are there are some plants that will start growing there naturally, given they have enough water.

But since we are concerned with what grows in our gardens, and we want it to be healthy, we do often need to do a little chemistry tweaking to bring our soil to a place that can grow the wide variety of food plants we want to grow.

Note that I’m not saying chemicals – just chemistry, which just means elements, found naturally all over our planet.

As organic gardeners, we aren’t particularly fond of the idea of having, say, our rock phosphate shipped from Idaho and our gypsum from California.

But we are fond of growing tomatoes and strawberries that are as nutritious as possible, and if we do get our soil into balance, we can ultimately decrease the shipping of a lot of food from around the world to our kitchen counters.

So how do you improve your soil chemistry?

I mention compost often. It’s a great start. It brings in small amounts of many different elements, so it’s especially useful to make sure you have enough of those trace elements we know less about but believe are very important.

These include elements such as selenium and arsenic (yes, soil, plants and people all need even arsenic in small amounts).

Seaweed
Seaweed is an excellent source of broad spectrum nutrition for soil and plants.

But you’ll probably also benefit greatly by using some organic fertilizers in the first couple of years.

You’ll do this in order to have more control over the quantity of certain elements in your soil, and in order to feed plants directly during those first years when your soil is still transitioning to being healthier.

These include:

  • Broad spectrum fertilizers that add small amounts of many different elements, such as rock dust, seaweed and even ocean water. These will benefit almost any garden.
  • More specific fertilizers that add larger amounts of just 2-3 elements. They are usually naturally mined rocks such as lime and rock phosphate. These should mostly be added only after you’ve done a soil test.

Some of these products may feed plants directly, but often we do this even more for the other biology in the soil, because it has just as important of a role to play…

Biology

Soil Forest Floor
An optimally healthy forest topsoil can be 80% microorganisms by weight! Many people who work with soil put that number at more like 5%, but that’s because they’re used to working with sick agricultural soils.

Biology refers to living organisms.

Without the biology, soil is just lifeless dirt.

But a handful of healthy soil might have more bacteria and fungi in it than there are people on the planet! And most of them are beneficial.

Through their growing, eating and being eaten, microorganisms rearrange the elements and soil particles to create a place where water and nutrients can be held, air can circulate, and animals and plants can thrive.

Plus they feed plants directly, so they’re really the link between the chemistry in the soil and in plants.

They’re a key part of getting the nutrition back into our food.

Soil microorganisms, plants and animals make up what we call the ‘soil food web.’ The main reason we work on balancing the chemistry is so the soil organisms – the biology – can do what they do.

Unfortunately, the biology is often deficient in our gardens because of past tilling, chemical fertilizers and pesticides, construction practices, drip irrigation and xeriscaping, monocultures, pollution, etc., so as with the chemistry, we may need to bring it back in.

You can learn about your soil biology by sending a soil sample to a biology lab that specializes in this kind of thing.

Fungi and bacteria
You can also get a microscope and learn to diagnose your soil yourself.

Doing this isn’t nearly as popular as chemistry testing, but is gradually becoming more accepted in the organic farming world and we may eventually see it as the more important test.

Once you have an idea of what you’re working with for soil biology, you can bring in the appropriate microorganisms through specific, homemade compost and compost teas, plus perhaps other microbial inoculants such as mycorrhizal fungi.

Adding regular high quality compost is the most important part because it will have a treasure trove of beneficial organisms, but it gets even more exciting when we learn to make compost specifically for our soil and crops.

For example, if you’re trying to grow broccoli, your bacteria-dominated soil may be fine – brassicas don’t even partner with mycorrhizal fungi.

But if you want to grow tomatoes or strawberries, you’ll want to get more fungi in the soil by making more of a fungal-dominated compost and compost tea.

And of course we want to stop doing the things which might have caused our biology to be deficient in the first place, which I’ll talk more about in part 2…

Bringing It Together

This topic is obviously huge.

Ants and Aphids
We’ll talk about pests in the next lesson. Unfortunately, these ants actually help these aphids rather than control them, but many other insects will control them both.

My aim with SmilingGardener.com is to share the basic principles for how to accomplish this.

I try to share just the right amount of detail to help people out with their gardens without overwhelming them.

My aim with my Smiling Gardener Academy is to share a much more comprehensive, step by step approach to accomplish this.

It’s for the people who are willing to put in a little work and study up front to grow nutrient-dense food for many years to come.

You can read more about the Academy here.

Your Garden

I’m really interested in your garden, whether it be 1/4 acre or 100 square feet.

I’m curious, what questions do you have about your garden this year? What have you been wondering about?

Part 2. Pests and Weeds

Updated Feb 25, 2017

Colorado potato beetle
Colorado potato beetle.

When a Colorado potato beetle decimates my tomatoes, potatoes or eggplants, it’s not because I’ve grown amazingly nutritious plants.

The beetles are actually there because my plants are unhealthy. So are the aphids, cutworms, scales and all other insect pests.

They can’t even digest plants that we would consider healthy.

Same with the mildews, wilts, molds and other diseases.

It’s an interesting piece of history that insects and diseases have evolved to remove the sick plants from our world in order to keep the whole system functioning.

And that dandelions, crabgrass, thistles and other weeds are there because my soil is imbalanced. They’re there to fix it. Thank you weeds!

This is a crucial lesson to learn because it helps us understand why we need to make the change from managing garden pests (e.g. IPM) to managing garden health.

The great thing about managing garden health is that we’re getting both nutritious food and pest control with the same principles.

Let’s continue our chemistry and biology discussion to see how it relates to the issue of not only nutrition, but pests and weed control too…

Chemistry

For plants to be optimally healthy, they need access to balanced nutrition.

When they have that, not only can they manufacture their own toxins to dissuade pests from eating them, but the pests won’t even try in the first place because healthy plants aren’t food for them.

Compost bin
My compost bin.

In my garden, well-made compost is the basis for this balanced nutrition.

By well made, I mean it was put together with a diverse array of ingredients that bring in a diverse array of nutrients and microorganisms.

I also mean that the moisture, air, temperature and carbon-to-nitrogen ratio of the pile were all kept within ranges that promote the healthy breakdown of these materials instead of putrefaction, and the proliferation of beneficial microorganisms instead of harmful ones.

The many nutrients in the compost are responsible for a lot of important things, from relieving compaction in the soil to photosynthesis in plants to everything in between.

But a main downside of compost is that it doesn’t allow us to deliberately manipulate specific nutrients into the correct ratios with each other the way we can with specific mineral fertilizers.

At the same time, I think most of us want to produce much of our fertility onsite because it’s more affordable and sustainable, so I can relate when my Academy members are hesitant to pay for a soil test and ship in fertilizers from across the country.

So when you’re starting out, feel free to work mainly with compost, mulch and cover crops at first. Those are great amendments to learn how to make and use, and they’ll get you a long way. The soil testing and fertilizers can come when you need them.

On the other hand, if you don’t have access to good compost, there are a few fertilizers that can very affordably bring in the nutrients your soil and plants need, especially in those first couple of years when the soil is still transitioning to being healthier.

Ocean water
Ocean water is an excellent fertilizer.

Rock dust, liquid seaweed and ocean water are the main ones I use. Ocean fish make an excellent fertilizer, too, although I’m concerned about the overfishing of our oceans, so I don’t use it as much.

In terms of specific elements, there is one worth using even when you haven’t done a soil test. That element is calcium.

Because most weeds and pests are there largely because of a calcium deficiency, getting sufficient calcium can go a long way to controlling them.

Calcium makes many good things happen. A deficiency of calcium makes many good things not happen.

That’s why I often say to add 5-10 pounds of calcium carbonate per 1000 square feet to your soil each year, even if you haven’t done a soil test.

Phosphorus is the next most important for dealing with pests, and then many of the trace minerals in compost, seaweed, ocean water and rock dust have a big role to play.

Biology

Let’s talk diversity.

First is microbial diversity.

Microorganisms bring food and water to plants, so they have a huge role to play in plant nutrition, and therefore pest control.

They also control bacterial and fungal diseases directly, in the soil and on plants.

Compost, compost tea, homemade teas, effective microorganisms (EM), indigenous microorganisms, mycorrhizal fungi and other inoculants will all bring in a different set of beneficial microbes that will keep diseases at bay.

Well made compost is the best one.

The main reasons we occasionally bring in these other inputs are because we may not have access to really great compost, and here’s where it gets interesting – compost can’t be applied to plant leaves.

What we’ve learned is if we can colonize the leaves with microbes from aerobic compost tea or EM, they can prevent and eradicate many diseases.

If we can colonize the roots with mycorrhizal fungi (not found in compost), they’ll do the same in the soil.

Then there’s animal diversity. Insect pests will be eaten by other insects and other animals if you have those other insects and other animals in your garden.

The way to attract beneficial insects is by using a wide diversity of insect-attracting plants that bloom at various times through the year.

Herbs are often really good at this, so my advice is always to plant as many different herbs as you can, even if just one of each – dill, cilantro, thyme, oregano, and at least a dozen others.

Many birds are also insect eaters, so invite them into your garden with bird feeders, bird baths and a diversity of food and habitat for them. Of course you may need to protect some of your crops such as cherry trees with bird netting, but that’s okay.

Frogs, snakes, bats and more – there are many insect controllers that will help us out if we make our gardens a place they want to live.

The more diversity we have in the garden, with wet areas, weedy areas, rock piles, evening-flowering plants, etc., the more helpers we’ll attract.

Polyculture
My garden looks pretty wild sometimes because I plant polycultures of many species of plants all mixed together.

Then there’s plant diversity. If you plant many types of food, when your potatoes get eaten by the Colorado potato beetle (because you probably have a deficiency, in this case, of Ca, P, Vit C, Cu and Mn), you’ll still have squash and carrots right nearby in good shape.

In fact, if you plant multiple species of potatoes in different parts of the garden, odds are that if one becomes pest ridden, the others will be fine.

It can also be helpful to plant many different species of plants close together. A simple example of this ‘companion planting’ is corn, beans and squash.

A more complex example, called a ‘polyculture’, is to plant 10-20 species all mixed together.

Some of those plants will confuse predators, while others will attract the predators of those predators.

Some will provide food for you, some will improve soil fertility, some will control weeds, some will break up compaction, and so on.

Bringing It All Together

There’s a lot to learn about getting the chemistry and biology right, but it’s absolutely fascinating to see how garden pests go away when soil and plant health are improved. Ants and Aphids
We’ll talk about pests in the next lesson. Unfortunately, these ants actually help these aphids rather than control them, but many other insects will control them both.

The most incredible phenomenon is when disease and insect pests move from your crops to your weeds, because that means:

  • Your plants are obviously healthier – that’s why the pests left them
  • Your weeds are obviously less healthy – that’s why the pests moved to them
  • Your soil is obviously healthier – that’s why the plants are healthier and the weeds are now sick, because most weeds don’t do well in balanced soil

When that happens – what an a-ha moment!

My aim with SmilingGardener.com is to share the basic principles for how to accomplish this. I try to share just the right amount of detail to help people out with their gardens without overwhelming them.

My aim with my Smiling Gardener Academy is to share a much more comprehensive, step by step approach to accomplish this. It’s for the people who are willing to put in a little work and study up front to grow nutrient-dense, pest-free food for many years to come.

Your Garden

I’d love to continue below with the discussion we’ve already started here.

What questions do you have about your garden this year? About pests? Weeds? Soil health? Plant health? Anything else?

Let me know down below in the comments…

Part 3. Your Blueprint

Updated Feb 25, 2017

I created the blueprint below to remind you of the most important things you can do to improve your garden over the next year.

You can right-click it to save it to your computer and even print it off if you like.

Smiling Gardener Blueprint

The strategies in the blueprint will help you grow highly nutritious, non-toxic food and a healthy organic garden that doesn’t have pest and weed problems.

There’s no particular order to the steps in the blueprint because it depends on your situation, but here’s a brief outline of the topics:

  • Discover your soil. Do some digging to see what you’re working with in terms of texture, structure, earthworms and insects, organic matter and water. This will help you make decisions around planting, watering, fertilizing and other amendments.
  • Chemistry soil test. Take a soil sample, send it to a good organic lab, learn to analyze the results or get recommendations from them. Then apply specific organic fertilizers based on those results to bring your soil chemistry towards balance. Also consider a soil contamination test.
  • Biology soil test. Send a similar sample to a biology lab to see what you’re working with. Then make specific composts and teas to bring your biology into better balance for the specific crops you’re trying to grow.
  • Prepare a bed. Prepare to either double dig or use some form of mulching, sheet mulching or rock mulching. Figure out what to do with the sod, and moderate heavy clay or sand with compost and fertilizers.
  • Composting. Find a good source of compost or make your own with a big bin outside, a worm bin, or bokashi. When it’s matured, apply max 1/4 inch over the whole soil area to improve fertility and most important, to bring in the beneficial biology.
  • Cover crops. Plant a mixture of legumes and grasses, and perhaps something else, during the off season to improve soil structure/fertility, increase organic matter, control weeds/pests, invite beneficial insects and other animals, and conserve water.
  • Fertilizers. Use broad spectrum fertilizers from the ocean (such as seaweed), from land (such as rock dust), from your kitchen (such as molasses) and others you make yourself (such as herbal tea) to improve soil and plant nutrition directly.
  • Design. Keep track of the sun, temperature and moisture on your property, set design goals, draw your site to scale on graph paper and make copies. Then you can start playing with bubble diagrams and multiple designs to see which will work best.
  • Growing food. Plan for some of the following: raised beds, trellises, extending the growing season with cold frames/hoop houses, polycultures of fruits, veggies and herbs, plus trees and shrubs to make a forest garden, containers for your balcony, and saving seed.
  • Planting. Choose plants and seeds from garden centres and online (local if possible) and start some seeds indoors. Sow seeds and plant starts when the time is right for each of them, and be sure to give them the biology and chemistry they need.
  • Inoculants. Brew some aerobic compost tea, activate some EM, cultivate some IM and apply mycorrhizal fungi and other inoculants to improve soil and plant biology. And compost is king here, too.
  • Pests. Control insects, diseases and weeds with homemade and purchased organic pesticides such as garlic, hot pepper, vinegar and neem oil, but more importantly, learn how to prevent pest problems by creating garden health.
  • Odds and ends. A well-designed garden doesn’t need much pruning or tending, but proper watering is important and it’s good to visit the garden regularly in the first year to keep an eye on things.

Here’s a video I’ve made explaining it…

These steps form the basis of a plan that has helped me grow a highly nutritious organic garden.

It’s the plan nearly 500 Academy members have used on their own gardens.

I hope the blueprint and this past week’s series have opened your eyes to a new way of thinking about your garden, because once you put these strategies into place, things will never be quite the same.

You’ll still have occasional setbacks because nature is a complex, dynamic system, but they’ll become much less frequent and will be balanced by astonishing successes.

I hope some people will take this blueprint and get started right away by continuing to educate themselves on how to use all of the strategies it contains.

If you do that, a very important piece of advice I have to give you is to check multiple resources for each topic in the blueprint because there’s a lot of poor information that gets passed around in the gardening world, including in the organic gardening world, especially online. If you can wade through that, with a bit of trial and error, you’ll gradually find your way…

The Academy

Harvesting Food
I’ve being teaching organic gardening since 2008 and doing research since I began gardening organically in 2005.

If my approach resonates with you and you want to implement it in your garden, my online gardening course ‘The Smiling Gardener Academy’ goes into detail on every topic in the blueprint, plus many other topics I kept out of the blueprint to keep it more manageable.

You can learn more about the Academy by clicking the ‘Academy Info’ button below.

9 Ways To Help The Beneficial Fungi In Your Soil

Applying beneficial fungiStarting seeds indoors for planting outside this spring – the inoculant goes on right before sowing the seed.

Without sufficient beneficial microbes on (and in) our bodies, we get sick very fast.

It’s the same for plants.

Perhaps the most beneficial fungi for plant health is a group of fungi you may have heard me talk about before called mycorrhizal fungi.

This week, I received a fresh batch of mycorrhizal inoculant, a powder that brings these fungi onto the roots of my plants. Read More

Growing Nutritious Food, Using Compost, And More…

Worm compost
My worm compost.

I once met a conventional apple orchard grower who refused to eat his own apples because of all the toxic pesticides he’d sprayed on them.

I once went to an organic apple orchard and couldn’t bring myself to buy any of their apples because they were so mealy and tasteless.

Although we like to think so, organic food doesn’t always taste better, which on its own is a shame, but the bigger deal to me is that the deficiency of taste also points to a deficiency in nutrition, which is common in organics.

But like the pesticide-spraying orchardist above, I don’t eat conventional apples. I try to buy mostly organic food because I want to stay away from pesticides/GMOs and I prefer to support the small organic farmers who are trying to find a more sustainable way of farming.

But what’s just as important to me is eating food that is nutritious, because poor nutrition in my food equals poor nutrition in me, which means various health issues that I’d rather not experience.

That’s why I grow my own food, because it can be made tastier and more nutritious using organic methods if it’s grown in an ecosystem that is teeming with a huge diversity of beneficial microorganisms and a balanced array of nutrients.

There are many strategies to accomplish this. Let’s look at one of them today: compost.

Compost helps with both of these things. It adds the nutrients, but more importantly, it adds the microorganisms. Most people don’t know it, but that’s the main reason to use compost.

Interestingly, compost would go a long way to help that conventional orchardist with his pest problems so he could stop the pesticide use, because it has tremendous disease-controlling capabilities when applied to the soil, and also when applied to plant leaves as compost tea.

I have 2 important caveats about compost:

  • The first may sound like common sense, but it bears stating: it must be good compost. There’s a lot of bad compost out there and it causes more harm than good. It needs to be made aerobically, with reasonable materials. It must smell good and look good. It’s best to make your own. Bad compost causes disease. Good compost fights disease.
  • The second is the really important one: Don’t use too much. Most organic gardening books say “the more compost the better.” That’s not it, though. You’re going to throw your nutrient ratios out of balance if you use too much compost. I did for years. It made the soil look and feel nice, but after a while, it didn’t produce well. How much is too much? If you look at the work of people like Elaine Ingham and the Luebke’s in Austria, they recommend a maximum of ⅛ inch of compost spread on your soil when you’re beginning, and 2-10 times less after that. We’re talking just a light dusting each year.

The moral here is that it’s highly worthwhile to learn how to make your own compost, even if just a small amount. Even a worm bin is really all most home gardeners need.

The reason I’m talking about compost today is because I’ve been reviewing various new research studies that have implications for organic gardening, and I’ve noticed that compost is still being researched (has been for a long time) with positive results.

I’m doing this review because I’m in the process of updating my online gardening course – the Smiling Gardener Academy – as I do every year.

I’m going to do a promotion for the course over the next week and then after that, I’ll stop accepting new enrolments for awhile so I can focus on helping my existing members in there.

If you think you might interested in joining the Academy, sign up for free below because I’m going to offer a special deal.

Also next week, while my head is spinning with excitement at all of these ideas, I’m going to share the most important strategies for helping you grow food that:

  • Tastes better,
  • Is much more nutritious, and
  • Doesn’t get eaten by pests
