HUMIC ACID TRIAL ON CLAY AND SANDY SOIL _ GRAND HUMUS PLUS

Clay soils have the smallest particle size of all soils. Soils with high clay content are prone to becoming dense and compact, so much so that they may resist plant rooting. Humic Acid has several effects on clay soil. It isolates and removes the salts from the clay particle, re-imparting a negative charge to the face of the particle. It loosens soil and allows the plant roots to penetrate and move deeper. Long-term use of humic acid has been shown to create a less dense, better drained soil capable of significant yield increases.
