Soil varies all over the world. Having said this, all soils have generally the same make up and contain the same minerals, in varying levels and availability. Soil life is relatively similar as well, varying in numbers and species based on the climate, soil type and farming practices.
The agriculture industry does not pay particular attention to the soil structure, but rather categorizes soil types by colour and zones, layers and parent material.
We take a bit of a different approach to soil, and to soil structuring.
Soil should be an interface between the atmosphere and the earth. 25% air and 25% water and 50% soil, microbes, plant material and humus. By achieving this structure, plants and soil life will thrive and be able to access all that is needed for survival.
This environment is what we refer to as the aerobic zone. Characteristics include a PSI of under 300, the soil is non sticky, has an earthy smell and decomposes plant residues in a short period of time. Conductivity readings become more homogeneous and water holding capacity improves. Soil microbes thrive, mineral availability improves, and there is a marked decrease in the presence of disease, insect damage and weed pressure. We do treat each soil type a bit differently, but the end goal is the same.
