Earth Oyster Shell
Helps prevent calcium deficiencies that can hinder plant development.
Oyster Shell is a natural, high-quality source of calcium, an essential nutrient for plant health. Sourced from ancient oyster shells, it is carefully harvested and ground into small, medium, and coarse particles. These irregular shapes allow for a sustained release of calcium, helping prevent deficiencies that can affect plant growth. Additionally, Oyster Shell improves soil structure and promotes optimal tilth, contributing to overall soil health.
