Good soil is a combination of dirt (clay, loam, sand), organic material (compost, manure), air spaces, water pores and lots + lots + lots of organisms (did I mention lots?). These organisms are the real unsung heroes of our time, doing the job of feeding our plants, and in turn feeding us. These are the bacterium, fungi, worms, nematodes, protozoa, algae… on and on, that consume the organic material (even each other) then excrete out the stuff of dreams (okay, maybe only of my dreams)… Fertilizer! All natural, organic and uncensored, this is the stuff that makes plants zoom! Delicious Tomatomania tomatoes, sweet carrots, perfect Zinnias; these are all byproducts of a healthy soil food ecosystem.
