5 Gardening Ideas from Building Soils Naturally

I FIRST STARTED READING PHIL NAUTA and his Smiling Gardener Blog in the fall of 2010. Right away, his blog struck me as different from the other how-to-garden-better blogs. It was obvious that Phil had a wealth of knowledge. Plus, his info was often quite a bit more “technical” than the others.

To give you a sense of what I mean, Phil regularly wrote about subjects like mycorrhizal fungi, biological transmutation and the brix test. You’ve got to admit that these topics are not what you’d normally find on blogs like A Way to Garden or Urban Organic Gardener.

One Smiling Gardener article that really got my attention was on how gardeners could potentially catch mad cow disease from  bone meal. Phil made a strong enough case against bone meal that I decided to stop using it on my flowers.

So when Phil offered a free review copy of his newly minted book called Building Soils Naturally*, I knew right away that it would be packed with interesting info. It didn’t take much convincing to get me to review it.

Building soil from A to Z

Phil’s book starts with the basics of improving your soil, some of which he also wrote about in his Suburban Hobby Farmer guest article. Then it progresses to the deeply technical aspects of determining and curing specific soil nutrient deficiencies.

Much of the information could only come from someone who has studied plant nutrition in some detail. No question Phil has studied. He started a natural fertilizer company and has taught organic horticulture at Gaia College, a school that teaches holistic land management and environmentally sustainable technologies.

There’s also no question that he’s against standard NPK (nitrogen, phosphorus, potassium) fertilizer. He challenges the proponents of NPK whenever he has the opportunity and encourages readers to go beyond even organic soil improvement methods with soil tests and what I’ll call exotic additives.

Unquestionably, parts of Building Soils Naturally will be more sophisticated than what many backyard gardeners will be willing to put into practice. Be warned, Phil frequently suggests seeking out and paying for soil additives. Regular readers of this site know that this goes against the spirit of Suburban Hobby Farmer, where I try to pay as little as possible for my soil improvement.

Paying will be worth it

Phil promises that paying will be worth it. He believes that once you reach the perfect soil for a specific plant, it will be invisible to insect predators and diseases. Produce will be tastier and much more nutritious. Plus, the shelf life will be greatly extended. In short, a fruit or vegetable grown in ideal soil conditions will be no less than a super food.

Building Soils Naturally

Nauta says building soil can make plants invisible to predators.

Phil is skilled at persuasion. He makes a great case for his methodology. Still, some claims seem too good to be true. Take Phil’s point that plants grown in ideal soil will be invisible to predators. This has not always been the case in my garden. My blueberries have nearly ideal conditions, including soil that is perfect for them. Yet, Japanese beetles are able to locate them and prefer them over other crops that have been weakened by less than ideal soil. My philosophy is nothing works 100 percent of the time.

Still, this book has more new ideas than anything I’ve read in a long time. There are many suggestions that I want to test in my garden. Here are five examples:

1. Water your soil microbes, not just your plants. Many gardeners, myself included, have been guilty of watering only in the root zone of my vegetable plants. I thought this was a good way to save water. The problem with pinpoint watering is that the soil life outside of the wet zone is deprived of water. Microorganisms, earthworms and insects need water as much as the plants, and the health of your plants depends on the health of these organisms.

2. Add seaweed to your compost. I’ve been thinking that seaweed would be a nutrient-rich, free source of material for the compost. This book gave me the kick in the pants to go get some. According to Phil, there’s no need to rinse the salt out before adding it to the pile.

3. Try diluted sea water as plant food. This is one of the most controversial ideas in the book. The premise is that sea water has minerals and active organic substances that will benefit your plants. Phil points to research by Maynard Murray that concluded that minerals from sea water increased yields and improved the overall health of plants. As you might expect, others believe that essentially “salting” your soil is a bad idea. I’m going to test a 10 percent solution of sea water on a small part of my garden. I’ll let you know if it works for me.

Cover crop should be a mixture of legumes and grasses.

4. Add hairy vetch as part of your cover crop. Phil makes the case that cover crop should be a mixture of legumes and grasses. Legumes add nitrogen to the soil and grasses provide high volumes of organic matter. He likes hairy vetch* as a legume because it captures the most nitrogen. He likes cereal rye as a grass because of the volume of organic matter it provides. I’m going to try a combination of the two this fall.

5. Inoculate your compost with new microbes. One way to get some diversity of microbes in your compost is to take a few handfuls of soil from an ecosystem that’s different from your garden, say a forest or a meadow, and add it to your pile. This will help create microbe diversity in your pile and ultimately your soil, which will help make for healthier plants.

There are many more interesting ideas about how to improve soil health in Building Soils Naturally. Most of these involve more expensive and often hard to find ingredients. Professional landscapers (organic) will be very interested in Phil’s suggestions because they must get superior results and often have a budget for buying soil amendments.

On the other hand, I’ve always felt that it doesn’t make sense to spend more on your garden than it would to buy organic produce. Of course, it’s tempting to invest in some of these ingredients when the benefit is ultra nutritious food.

Stay tuned for the next article. I’ll be giving away my promotional copy of Building Soils Naturally and let me know what you think of diluted ocean water as a soil additive by commenting below.

    Hi Bill,this year has to be the worst gardening year i have ever had as far as weather goes.My crops are a lot later than normal but are starting to come.I have been doing quite a lot of testing this year myself this year,i think the climate is changing so much each year now that it is time to change my gardening methods.Just by what i have read here the smiling gardener may have some good points,i must check out his blog.I have managed to keep away from chemical fertilizer this year,only used compost.I have also changed the way i water my plants with good results.The only thing with just using compost is everything grows a little slower but i seem to be getting more produce even though the season has not been good.I am going to be adding all my changes and results on my garden page on facebook as the season comes to a close.Just to give you an idea,i built 2 raised beds this year just to try them,this is the way to go.One more thing i did this year was not hill up my potato’s,i left the ground flat,it takes less time for the water to reach the root this way and i have never seen so many potato’s on one root.There is so much to tell.I should not admit this,i have never in all my years of gardening had my soil tested,i go by looks,feel and smell.

      I’m sorry to hear that your crops are slower than you’d like, but it sounds like your doing pretty well anyway. Amazing that you are getting more potatoes without mounding up the soil. I’m glad to hear that you’ve moved away from synthetic fertilizer. I think that’s the way to go. I know it can be challenging. I’m going to watch for your Facebook update. I look forward to it.

    I guess i am not doing that bad,it is just that i am used to doing better.

    Interesting suggestions, I had read recently that you can use sea salt to improve the soil quality – sounds counter intuitive. 🙂

      I’ve also heard of people putting Epsom Salt on their soil, too. I’m not sure how you could put a small enough amount not to damage your soil. Still, it’s pretty much the same as putting diluted sea water on your garden soil.

        I suppose in small quantities the soil can use the extra minerals, but I wouldn’t want to try regular table salt, probably not enough minerals left after processing. I wonder at what level of concentration it starts damaging the soil.

          I have no idea how much is too much, Maynard Murray is the researcher who has studied this. You probably could find it in some of his research papers.

    I use Epsom Salts on my tomato’s every year Bill,finest thing you can use.I put some in my potting mix when i re-pot,i also sprinkle 1 teaspoon full around the hole when i plant them in the greenhouse.About 20 odd years ago i used to get the odd tomato with blossom end rot,since using Epsom Salts i never see any.Some of my gardener friends used to get yellow leaves at the bottom of their plants in the growing period.Now they use Epsom salts and they don’t get them anymore.

      There you go Chris, Bob uses a teaspoon full when he plants his tomatoes. That probably gives you an idea of how much you need.
