Organic Fertilizers - Composition (Videoman)
Organic Fertilizers - Composition . Organic soil composition involves creating a soil medium that has a balanced amount of nutrients - NPK as well as trace elements and minerals - plus organic material that provides food for not only the plant, but also the countless soil microorganisms, fungi, worms, and bacteria that comprise a healthy soil. This soil life breaks down the raw materials of the fertilizers you add so the plants can absorb them, and also plays a part in as-yet undefined processes that aid plant growth and improve soil health.
Below are various "recipes" for both organic fertilizers and organic soil mixes.
Mix and match formulas
Pick one source from each category. The results will vary in composition from 1-2-1 to 4-6-3, but any mixture will provide a balanced supply of nutrients that will be steadily available to plants and encourage soil microorganisms.
