I’m a big fan of organic liquid fertilizer.
But there’s also an important use for organic dry fertilizer.
I use liquid fertilizers mainly to provide small amounts of 80+ nutrients directly as a plant fertilizer, and also as a soil fertilizer.
Doing this plays a big part in helping me grow nutrient-dense food.
And yet some nutrients we need in the soil more than others, the big three in the organic world being calcium (Ca), phosphorus (P) and potassium (K).
We need to have enough of them in the soil, but not too much.
(I know that npk fertilizer is stressed in the conventional world, and yes, nitrogen fertilizer is sometimes useful too, but it’s really not all that hard to get enough nitrogen – calcium is much more important to get right, so that’s my focus today).
The benefits we get when we move those three minerals in our soil towards the ideal amounts are many: healthier plants, fewer pests and weeds, better soil structure, etc.
I recently started selling my favorite organic liquid fertilizers, the same ones I use at home.
But I also like to make my own homemade liquid fertilizer when possible, and that’s what I’m excited to show you today.
Many of our best liquid fertilizers come from the ocean.
But there are ways you can approximate them, if like me, you don’t live near the ocean.
All of these can be used as a liquid lawn fertilizer, liquid plant fertilizer and liquid soil fertilizer.
You might even make enough for multiple applications (such as monthly or weekly).
For all of these homemade fertilizers, I suggest mixing with at least 10 parts water before you spray.
That will allow the fertilizer to cover more area and will ensure we don’t burn our plants.
And it certainly doesn’t hurt to mix with even more water…
The least expensive organic fertilizer in the world is – cover crops!
Cover crops for gardens are simply plants that are planted to cover your soil, especially during the off season.
And they can also be used during the growing season, interplanted with food crops or even in ornamental beds.
There are a handful of very useful natural organic fertilizers for you to choose from, especially if you look online.
The hard part is knowing which ones to choose, but I’ll give you a few things to look for.
Natural organic fertilizers don’t look like much of a bargain compared with the high nitrogen-phosphorus-potassium numbers on chemical fertilizers, but they’re so much more valuable.
10-10-10 fertilizer is one of the most popular fertilizers.
This week, I received a great question about the nutritional difference between 10-10-10 and compost:
Most bags of compost and manure say they have about .1-.1-.1 of the big 3. I have tested my own compost and it is somewhat higher but still not in the 10 10 10 range recommended for most plants. So, how do you get enough without using fertilizers? Is 10-10-10 the same as .1-.1-.1? Am I missing something?
I’m glad you asked. There are 3 things I’d like to address…
Today I continue with the garden fertilizer tips.
Last week, I outlined a basic fertilizer schedule and received a couple of comments from people who disagreed with my suggestions, so I thought I’d address their concerns here in more detail.
I always appreciate any feedback people have to give, even when it runs counter to my advice. Some great learning opportunities come when we have these discussions.
If you want a fertilizer schedule to follow, I have some tips for you.
Fertilizer companies often create a schedule for you that outlines exactly when to fertilize, but that’s often done to maximize their revenue, not the health of your garden.
The thing is, there’s no such thing as an off-the-shelf fertilizer schedule that is right for every garden. We can, however, follow some well-established guidelines.
Mining limestone is big business, but does it give us a sustainable fertilizer?
The world’s biggest limestone quarry is right near the top of the state of Michigan on Lake Huron.
It’s 7000 acres, roughly half the size of Manhattan.
I’m not sure how much of the material from this particular quarry goes toward agriculture, but lime is certainly one of the most important fertilizers in farming and gardening, especially in organics.
What is paramagnetic rock dust? Well, let’s start with paramagnetism.
The soil in your organic garden is paramagnetic. It isn’t magnetic, but is mildly attracted by a magnet and partially aligns with the earth’s magnetic field, so it’s paramagnetic. Some soils are attracted more than others, and generally, the more paramagnetic your soil is, the better.
This is apparently because highly paramagnetic soils are more energetically aligned with the earth and even the universe, and actually invite energy into them.
