Collection: Calcium Rich Fertilizers
Calcium Fertilizers for Plants and Soil
Shop calcium sources including gypsum, oyster shell, limestone products and blended fertilizers. Products differ in calcium concentration and in their effects on soil pH, sulfur supply and other soil properties.
Choosing and Applying
Use a soil test to distinguish a calcium need from a pH problem. Compare analysis and label directions; lime, gypsum and oyster shell are not interchangeable.
Compare pH-correcting products, soil tests and other nutrient-specific fertilizers.
