As you create your own nutrient program, it is often helpful to know the NPK (nitrogen-phosphorus-potassium) value for different fertilizer components. Follow these links for the NPK values of these organic fertilizers: bat guano, more animal manure options, bone meal and blood meal, worm castings.
