When you get a professional soil test done, you typically get back a report stating various nutrient levels, pH, structure, texture and ability to hold nutrients. But modern day tests are leaving out the most crucial component to soil health, and that is the biology living within it. When we till our soil, or apply inorganic fertilizers, pesticides, herbicides and fungicides, we wipe out the biology (the bacteria, fungi, protozoa, nematodes, microarthropods etc) that the plants depend upon for survival.
The biology in the soil is responsible for keeping diseases and pests in check, holding nutrients within the root zone (so they’re not lost to leaching), creating soil structure and converting insoluble nutrients into plant soluble forms. The biology also make it so that you never have to add any amendments to your soil….ever! All of the nutrients that plants require exist within the sands, clays and silts (mineral components of the soil). All that’s required is a balanced soil food web to hold and convert them into plant soluble forms.
