The
Uses of our Products As a Fertilizer |
 
 |
| SOP (Sulphate Of Potash) As A Fertilizer: | |
| Potassium Sulphate or Sulphate of Potash (SOP) is a
two-nutrient fertilizer containing 50% K2O equivalent, and 18% Sulphur.
Potassium Sulphate is a water-soluble, neutral salt, and has no effect on soil acidity or alkalinity (pH). Potassium and Sulphur are essential elements vital to many functions within the plant. |
|
| Potassium - (K): | |
| Potassium is an immobile nutrient in the soil, moving
slowly and for only short distance (by diffusion) through moisture
films on soil particle surfaces. It can leach in very sandy or organic
soils, but seldom leaches out of the crop root zones.
Nearly every aspect of plant growth is dependent upon an adequate supply of Potassium (K). Potassium helps to improve plants' disease resistance, tolerance to water stress, winter hardiness, tolerance to crop pests, and increased efficiency of (N) use. Providing adequate amounts of Potassium in fertilizer to meet current crop needs and to build soil (K) levels is critical to sustain profitable crop production. This essential nutrient is required in greater amounts than any other nutrient except (N) and some crops take up more (K) than (N). Only when the soil is adequately supplied with (K) can optimum crop production be sustained. |
|
| Sulphur - (S): | |
| Sulphur fulfils several important functions in the
plant. There can be no protein without (S). This nutrient is needed
to make chlorophyll, enzymes, vitamins and other essential compounds
in the plant. Sulphur deficient plants are often uniformly chlorotic,
stunted, thin-stemmed, and spindly.
Sulphur is present in SOP in the sulphate ion (SO 4) form. The sulphate is metabolized by the plant, and the (S) becomes an integral part of plant compounds, vital to plant metabolism. |
|
| The agricultural advantages of SOP: | |
| * Supplies the crop with both (K) and (S).
* Has the lowest salt index among conventional potash fertilizers. * Preferred for (Cl) - sensitive crops such as potatoes, canola, tomatoes, clover, peas, beans, oats, wheat, alfalfa, tobacco, cool season grasses, ornamental plants, etc. * Compatible with late (K) applications just before planting. Recognition of the increasing needs for supplemental Sulphur in crop production, combined with the established roles of (K) and (S) in plant physiology makes SOP a component of choice in balanced plant nutrition. |
