SOIL HEALTH - SUSTAINABLE AGRICULTURE

Healthy soil is a combination of minerals, rock, water, air, organic matter (plant and animal residue), microorganisms, including bacteria, fungi and protozoa and a variety of insects and worms. This intricate web carries out a process that continually replenishes the soil and maintains long-term soil fertility.For sustained growth, plants require macro-nutrients and trace elements. Macro-nutrients include, nitrogen (N), phosphorous (P), potassium (K), calcium (Ca), magnesium (Mg) and sulfur (S). Trace elements include, iron (Fe), manganese (Mn),copper (Cu) and zinc (Zn). For optimum plant growth, soil must be capable of storing these nutrients and transferring them to the root surface for uptake by plants.CB-RSG plays a major role in this process. It biodegrades non-living organic matter already in the soil thereby building structure and providing abalanced supply of nutrients and trace elements ina form that is readily available to plants. The ongoing degradation of soil organic matter replenishes and maintains long-term soil fertility by providing optimal conditions for soil biological activity."A nation that destroys its soils destroys itself. Forests are the lungs of our land, purifying the airand giving fresh strength to our people."Franklin D. Roosevelt
