phosphate clay products for use as soil wetting agents, methods of delivering soil phosphates and phosphate clay coatings for water retention purposes

摘要

summary “phosphate clay products for use as soil wetting agents, methods of delivering phosphate clays to the soil and phosphate clay coatings for water retention purposes” are phosphate clays and the use of phosphate clays as a wetting agent of soil. Phosphate clays as wetting agents assist in water retention in sandy soil, and / or in preventing or reducing nutrient leaching. Due to its unique particle size and shape, phosphate clay exhibits high absorption and retention qualities. Additionally, phosphate clay is readily available as a byproduct of a phosphate ore. Phosphate clay wetting agents increase the effectiveness of water applied to the soil, thereby reducing the amount of runoff and reducing the amount of water required to perform sufficient irrigation. phosphate clay wetting agents can be delivered to the soil as a spray product, spray product, soil correction, fertilizer or seed coating or fertilizer composition.
