SHAC Revitagro Soil Conditioner SOIL ORGANIC MATTER It has been widely acknowledged for many years that the key to soil fertility is organic matter. Soil organic matter often contains many nutrients and trace elements that have been stripped from the soil through human activity. The use of chemical fertilizers, though capable of improving plant growth, is simply not sufficient in replenishing the structure and fertility of the soil. In general, the addition of organic material, and more specifically humic substances, has been shown to improve soil quality and productivity.

FACT: Soil organic matter impacts soil aggregation, tilth and soil water characteristics.

FACT: Soil water holding capacity, permeability, infiltration, and surface crusting are improved with the addition of organic matter to soil.

FACT: Soils high in organic matter tend to be more productive and more biologically active.

HUMIC ACID IN SOIL SHAC Revitagro is an excellent source of Humic Acid. Humates and humic acids act in many important ways to make soil more productive and fertile. • Humates (metal complexes of humic acid) help to supply growing plants with food. They also act in other important ways to make soil more productive and fertile. • Humic substances break up unproductive clay soils, turning them into profitable soils. • Humic substances increase the water holding capacity of soil; therefore, helping plants resist drought. • Humic substances help retain water soluble inorganic fertilizers, releasing them as needed to growing plants, and help prevent nutrient leaching (through chelation). • Humic substances result in increased aeration of soil. • Humates establish a desirable environment for microorganism development in the soil. • Humic acids form stable complexes with metals (ex. chelation of salts), thereby limiting the effects of soil salinity.
