CMS

Calcium, Magnesium and Sulphur are known secondary nutrients. Each is having definite roll to play. It is best of soil conditioner. Green’s CMS play a vital role in supplying the above mentioned nutrients to the plant. The secondary nutrients like sulfur (S), magnesium (Mg) and calcium (Ca), do not always get the recognition of some others, but they are essential and play key roles in the growth and health of plants, animals, and humans. They have been called the “synthesizers” because of their functions in living organisms. Many factors can affect the availability of these three nutrients to plants. The best estimates of their availability can be determined by soil analysis or a combination of soil and plant analyses. However, field observations and deficiency symptoms are also important diagnostic tools.

Calcium plays an important role in lengthening the roots and shoots and there by improving the growth and development in plants Calcium requirement of yielding plant is quite high and it is more during the flower setting and seed ripening. 90% of calcium uptake is during flowering and pod formation stages. An important aspect of calcium nutrition in Coffee and Tea is that the calcium taken up by the plant from soil will remain in the leaf tissues, and will not move from the leaves to the developing pods where its requirement is high. For this reason calcium should be sufficiently available in the podding zone at peg formation stage to pod maturity. To get good yields of quality Crop, adequate amount of calcium should be present in the soil from early flowering of the crop onwards.
