SOIL HEALTH - SUSTAINABLE AGRICULTUREHealthy 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 a balanced supply of
nutrients and trace elements in a 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
air and giving fresh strength to our
people."
Franklin
D. Roosevelt
