I’ve carried out knowledge assortment to point out the observable distinction in soil organism habitat to the bare eye. It was a quite simple course of (that are ones I like finest, as a result of they’re so sensible and transferable to anybody anyplace). I walked my fields and adjoining farm fields, and folks’s gardens in early spring after the lengthy chilly northeastern winter.
Most fields are naked soil by winter and spring. Nevertheless, there may be at all times straggling weeds or particles.

But, if we’ve cowl crops established in our gardens at instances of the 12 months when the backyard isn’t rising crops, then these cowl crops can act as nutrient sponges, taking on the soluble vitamins and changing them to natural matter.
