I recently interviewed Dr. Elaine Ingham,8 an internationally recognized expert on the benefits of sustainable soil science. I also recently visited her at her new position at the Rodale Institute in Pennsylvania. According to Dr. Ingham, a key component of successful agriculture lies in having the right helper organisms in the soil; beneficial species of bacteria, fungi, protozoa, beneficial nematodes (not the weedfeeders), microarthropods, and earthworms—all of which contribute to plant growth in a number of different ways.
Nutrient cycling is another major issue. According to Dr. Ingham, there’s no soil on Earth that lacks the nutrients to grow a plant. She believes the concept that your soil is deficient and needs added phosphorus or nitrogen etc in order to grow plants is seriously flawed, and largely orchestrated by the chemical companies, because it’s based on looking at the soluble, inorganic nutrients that are partly present in your soil.
The real nutrition your plants require is actually derived from microorganisms in the soil. These organisms take the mineral material that’s in your soil and convert it into a plant-available form. Without these bioorganisms, your plants cannot get the nutrients they need. So what you need is not more chemical soil additives, what you need is the proper balance of beneficial soil organisms. According to Dr. Ingham:
“It’s very necessary to have these organisms. They will supply your plant with precisely the right balances of all the nutrients the plant requires. When you start to realize that one of the major roles and functions of life in the soil is to provide nutrients to the plants in the proper forms, then we don’t need inorganic fertilizers. We certainly don’t have to have genetically engineered plants or to utilize inorganic fertilizers if we get this proper biology back in the soil.
If we balance the proper biology, we select against the growth of weeds, so the whole issue with herbicides is done away with. We don’t need the herbicides if we can get the proper life back into the soil and select for the growth of the plants that we want to grow and against the growth of the weedy species.”
Interestingly enough, you can use a starter culture to boost the fermentation and generation of beneficial bacteria much in the same way you can boost the probiotics in your fermented vegetables. For compost, this strategy is used if you want to compost very rapidly. In that case, you can use a starter to inoculate the specific sets of organisms that you need to encourage in that compost.
For optimal physical health, you need plant foods to contain the full set of nutrients that will allow the plant to grow in a healthy fashion, because that’s the proper balance of nutrients for us human beings as well. Dr. Ingham has written several books on this topic, including The Field Guide for Actively Aerated Compost Tea, and The Compost Tea Brewing Manual.
