About organic fertilizers

Organic fertilizer comes from plants, animals and mined minerals. Any combination of organic fertilizer will feed soil organisms who produce plant food in a plant available form. Use powdered, pelleted and tablet fertilizer for soil application. Use organic liquid fertilizer or water soluble fertilizers via irrigation or foliar sprays.

Examples of organic fertilizers

  • Plant fertilizer - sea kelp (seaweed), alfalfa meal, corn gluten meal and cottonseed meal;
  • Green manure - living cover crop plants turned into the soil;
  • Natural fertilizer from animals - blood meal, bone meal, fish meal, and composted chicken manure;
  • Mined natural fertilizer - limestone, soft rock phosphate and gypsum.

How To Get Started The best way to evaluate your own situation is to start with a soil test.

Note to Certified Organic Farmers: While we do our best to stay current with product OMRI listings, be sure to check with your certifying organization for a current list of approved (or banned) products.
