Organic Fertilizer
Organic Fertilizer 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.
Long—Term Soil Building A successful fertilizing program addresses the soil's long-term needs by adjusting deficient nutrients with organic fertilizers and soil amendments. We offer the largest selection of organic fertilizers in the U.S.
How Much Organic Fertilizer Do You Need?
Understand how much fertilizer to add to your organic garden soil by soil testing to know exactly what nutrients your soil needs. Peaceful Valley's laboratory soil testing provides results for treating your soil organically. Once you know your % soil organic matter, nutrient content, pH, and cation exchange capacity you can use our booklet "Understanding Your Soil Analysis Report" to interpret your test results and our Fertilizer Solutions Chart to choose the best products for your organic garden. Even without doing any soil testing, most garden soil will give good results if simply amended with organic compost, a balanced N-P-K organic fertilizer, and a source of
Trace Minerals.
Nutrient Knowledge Nitrogen is what plants need for vigorous vegetative growth.
If your crop needs additional Nitrogen see Bloodmeal, Cottonseed Meal, PVFS Liquid Fish, Fish Meal, Pelleted Fertilizers, Feather Meal, and others.
Phosphorus is what plants need to flower, fruit, and for root development. To supply Phosphorus, Soft Rock Phosphate is the best value. Bone Meal can also be used.
Potassium is what plants need, among other things, to establish vigor and resistance through sugar formation. To supply Potassium use Sulfate of Potash or Greensand.
Calcium builds sturdy cell walls in plants. Many soils need Calcium fertilization. In low pH soils, use Oystershell Lime or Mined Limestone which corrects not only calcium imbalances but also pH. In neutral or high pH soils, Gypsum is the material of choice, it also provides sulfur. Calcium builds sturdy cell walls in plants.
Trace minerals are as essential to plants as vitamins are to people. Almost every field we test is low in Trace Minerals. We get excellent response from soil applications of Compost, Algit Kelp Meal or multiple trace minerals (Azomite or Nutra Min). In extreme cases specific trace mineral supplements may be needed.
