Healthy soil results in more nutrient-dense food.
Healthy soil occurs when, through proper crop rotation and fertility management, the micro-nutrient levels in the soil are kept at a perfect balance.
We encourage you to learn about healthy soil by visiting the Soil Foodweb, Inc. website at http://www.soilfoodweb.com. Here's just a little information to get you started.
A healthy foodweb occurs when:
- All the organisms the plant requires are present and functioning.
- Nutrients in the soil are in the proper forms for the plant to take-up. It is one of the functions of a healthy foodweb to hold nutrients in non-leachable forms so they remain in soil, until the plant requires the nutrients, and then the plant “turns-on” the right biology to convert the nutrients into forms the plant can take-up (but which are typically very leachable).
- The correct ratio of fungi to bacteria is present, and ratio of predator to prey is present, so soil pH, soil structure, and nutrient cycling occur at the rates and produce the right forms of nutrients for the plant.
The functions of a healthy foodweb are:
- Retention of nutrients so they do not leach or volatilize from the soil. Reduction or complete deletion of inorganic fertilizer applications is possible.
- Cycling nutrients into the right forms at the right rates for the plant desired. The right ratio of fungi to bacteria is needed for this to happen, as well as the right numbers and activity of the predators.
- Building soil structure, so oxygen, water and other nutrients can easily move into the soil and into deep, well-structured root systems. Current concepts of plant root systems as being at the surface of the soil is the result of current agricultural and urban practices, not a real condition of plants. Roots should go down into the soil for at least several to 10’s and perhaps 100’s of feet, but the compaction that humans impose on soil results in toxic materials being produced, preventing good root penetration. The only way to deal with this is to have the proper biology build the structure in the soil again, so oxygen and water can move into the soil. When the biology is functioning properly, water use is reduced, the need for fertilizers is reduced, and plant production is increased.
- Suppression of disease-causing organisms through competition with beneficials, by setting up the soil and foliar conditions to help the beneficials instead of the diseases.
- Protection of plant surfaces, above or below ground by making certain the foods the plant surfaces release into the soil are used by beneficial, not disease organisms, making certain that infection sites on plant surfaces are occupied by beneficial, and not disease-causing organisms. And by making certain predators that prefer disease-causing organisms are present to consume disease-causing organisms.
- Production of plant-growth-promoting hormones and chemicals can result in larger root systems, although whether forcing larger root systems on plants is a positive result needs to be understood.
- Decomposition of toxic compounds
