Agriculture in present situations depends on artificial fertilizers. Nutrition and mineral made into granules that helps the farms to purchases them and use it as it is to the crops. The field of fertilizer technology brought number of advanced fertilizers into market to improve the production rate. Even though the most concepts are, well-established medium and low-level farms cannot afford to buy them. Governments provide sufficient subsidies to help farmers. Due to fluctuations in the economy the percentage of dependence on governments cannot guarantee every farmer overall. This give rise to idea of control released fertiliser utilisation.
A private and an innovative farmer need a simple and low cost fertilizer. Therefore, an engineer or technologists have chance in this field to provide solution and earn benefits. Each step of research on this concept will have a value with sufficient rewards.
One problem statement for which regular farms wait for solutions is to get a control released fertiliser that release the nutrition and mineral to the plant with consistence rate. When a regular fertilizer is used as on when it falls on the soil it dissolves into the water and penetrates into soil. Plants and corps roots absorb these nutrition’s but the plant does not use half the percentage of nutrition. The reason for this would be most fraction of all the fertilizer might be lost into water flow out or atmosphere due humidity and rainfalls. Even plant may not use complete composition at once that is why a schedule maintained for applying the fertilizer to a standard agriculture field.
Principle of control released fertiliser working
This problem can be solved when the granule of the fertilizer works out the schedule of releasing of nutrition and minerals with constant rate into the soil. If a pellet is made with a compounds that make potassium, nitrogen, phosphorous and others salts coated on its surface and inside, so that they diffuse out with standard rate into the water and soil where their concentrations maintained at the roots of the crops.
Control released fertiliser decrease the excess use of chemical processed fertiliser and so prevent the soil, air and water pollution directly..
