From backyard vegetable gardens to large ultra-modern farming operations, more and more growers are choosing organic fertilizers as a smart alternative to chemical treatments. Organic farming is certainly not new, but it has found a renewed interest as a means to improve the natural fertility of soil and farm resources. For many people, organic fertilizers provide the answer to nutrient deficiency in soil.



To produce their own natural organic fertilizer, some farmers use traditional practices such as recycling farm-produced livestock manure, practicing crop rotation, or composting organic materials. When factors like innate nutritional shortages in regional soils and high productivity demands make these traditional means inconvenient, farmers may choose to purchase organic fertilizers and soil additives from specialty suppliers and organic fertilizer dealers. Listed below is a resource for farmers and gardeners of organic fertilizer dealers and suppliers in the United States and bordering countries.
