  • Fertilizer - "Fertilizers typically provide, in varying proportions: Six macronutrients: nitrogen (N), phosphorus (P), potassium (K), calcium (Ca), magnesium (Mg), and sulfur (S); Six micronutrients: boron (B), chlorine (Cl), copper (Cu), iron (Fe), manganese (Mn), molybdenum (Mo), and zinc (Zn)... [and three other macronutrients]: carbon, hydrogen, and oxygen. These nutrients are supplied by water and carbon dioxide." - Wikipedia
  • Organic fertilizer - "Naturally-occurring organic fertilizers include manure, slurry, worm castings, peat, seaweed, humic acid, and guano... Processed organic fertilizers include compost, bloodmeal, bone meal, humic acid, amino acids, and seaweed extracts. Other examples are natural enzyme digested proteins, fish meal, and feather meal. Decomposing crop residue (green manure) from prior years is another source of fertility." - Wikipedia
