Rock Phosphate 0-3-0 (5 lb)

Soft rock phosphate, also known as colloidal phosphate, is a natural untreated source of phosphorus and calcium. It is essential for building soil phosphate levels for long-term plant productivity and for preventing calcium deficient soils. It should be applied to soils prior to planting and can mixed with compost or manures for additional soil building benefits. The premium powder grade is an excellent nutrient resource for all types of flowering plants including bulbs, fruits, shrubs, trees and vegetables.

How Rock Phosphate 0-3-0 (5 lb) fits a fertility plan

• Provides phosphorus to support root development, flowering, seed formation, and fruiting when soil levels and crop demand justify an application.
• Its low or zero nitrogen analysis can fit programs that need phosphorus without a large additional nitrogen input.
• The package size and formulation shown in the title help match the product to planting holes, beds, containers, orchards, or larger areas as allowed by the label.

Application guidance: Phosphorus moves slowly in many soils and can accumulate when overapplied. Use soil-test results, place or incorporate only as directed, and account for phosphorus already supplied by compost and other fertilizers. Follow label rates for the specific crop and growth stage.
