Organic – In popular usage, all products of natural origin are organic. In fertilizers: manure, fish, and sludge, are organic; chemical plant foods derived from the air or from minerals and synthetically produced are called inorganic. Proponents of organics point out that soils become less “friable” when inorganics are used. Users of inorganic plant foods recommend regular additions of compost or some other type of humus to maintain soil structure and bacterial life. The combination of humus and fertilizer has proved itself everywhere.
