Granular Rock Phosphate + Sulphur (GRP + S)

Features & Benefits

• • Dual-Action Nutrient Release: GRP+S provides a steady, long-term supply of phosphorus from the rock phosphate, complemented by the elemental sulfur which gradually converts to sulfate, making it available for plant uptake.
  • Enhanced Phosphorus Availability: The addition of sulfur is key. As elemental sulfur oxidizes in the soil (a process mediated by soil microbes), it forms sulfuric acid, which helps to acidify the soil micro-environment around the granules. This process significantly improves the dissolution of the rock phosphate, making the phosphorus more readily available for plant roots to absorb.
  • Stimulates Soil Microbes: The sulfur acts as a catalyst, promoting the activity of beneficial soil microbes. These microbes are essential for breaking down organic matter and converting insoluble nutrients like phosphorus into forms that plants can use.
  • Improves Soil Structure: The combination of nutrients and microbial activity contributes to better soil structure, aeration, and water retention, creating a healthier environment for root growth.
  • Long-Lasting & Efficient: This blend reduces the need for frequent fertilizer applications, providing sustained nutrition throughout the growing season.
