Collection: Powdered Fertilizer
Ensure a bountiful harvest with organic fertilizers!At the heart of all organic growing is the art and science of fertilizing organically. The choice of what and when to apply a fertilizer will depend on your soil analysis and the stage of plant growth you are targeting.

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. Use your soil test and/or the general guidelines given ahead to determine which fertilizers will be of most value to you. An equally important aspect of soil building is adding a "green manure" cover crop to your crop rotation in order to build organic matter, nitrogen and biological life in your soil.
- 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 for vigor. 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 essential to plants. Almost every field we test is low in Trace Minerals. We get excellent response from soil applications of Compost, Kelp Meal or multiple trace minerals (Azomite or Nutra Min). In extreme cases specific trace mineral supplements may be needed.
