Nutrient-Specific Fertilizers
Shop fertilizers by primary nutrient, including nitrogen, phosphorus, potassium, calcium, sulfur, magnesium and trace minerals. These products are useful when a soil test, tissue analysis or established crop program identifies a particular need.
How to Choose
Different materials supply nutrients at different concentrations and release rates. Confirm the guaranteed analysis, application rate, soil pH considerations and label restrictions before applying a targeted nutrient.
Compare nitrogen, phosphorus, potassium, calcium and trace mineral fertilizers.
