Organic Fertilizers

Organic fertilizers are made from animal or plant sources. Even though not derived from animal or plants, some fertilizers or soil amendments that contain nutrients, are mined from the earth and OMRI approved or listed for use in organically certified production. OMRI approved products have been included in Viragrow’s list of organic fertilizers.

Blood Meal 12-0-0        3 LB & 15 lb     Salt Index = 2.8                                          

Blood meal is used as an organic nitrogen fertilizer for plants. Most blood meal contains 12% nitrogen. Since the nitrogen in blood meal is in organic form, it is released slowly to plants giving them a gentle boost in growth and production. Blood meal can be used in certified organic production of vegetables and fruit. Blood meal can also be used as a deterrent to rabbits when there are alternative sources of food. Blood meal can be used as a compost activator and supplies an organic form of nitrogen for compost microorganisms. 

Incorporate 5 lbs. per 100 square feet, 2 to 3 lbs. per 100 linear feet of row or 1 tbs. per 5 gallon container.

Bone Meal 1-15-0           15 lb.     Salt Index = 1.8                                                             

Bone meal is used as a slow-release, organic phosphorus fertilizer in certified organic production. Most bone meal contains about 6 ½% phosphorus (15% P2O5). Phosphorus fertilizers are usually mixed into the soil before planting seed or transplants. Finely ground bone meal releases phosphorus more quickly than bone meal which is coarsely ground. Soils which are more acidic release phosphorus more quickly than those which are alkaline. Applications of soil sulfur, compost teas, peat moss and other soil acidifiers assist in the release of phosphorus to plants. 

Incorporate 10 to 15 lbs. per 100 square feet for new planting. Sidedress with 5 lbs. per 100 foot of row.

Kelzyme     “Rock Dust”. Available in 8 lb. and ton quantities                  

Kelzyme is mined from ancient marine sediments in northern Nevada. Kelzyme contains a myriad of trace minerals normally eroded during irrigations or cropping cycles. Kelzyme is OMRI approved for organic livestock feed and crop fertilizer/soil amendment. Mineral analysis conducted by Wallace Laboratories in El Segundo, California, is available upon request.
