Fertigation is the practice of providing water-soluble fertilizers through water to increase the productivity of crops.
The use of plastic mulch is very effective as drip irrigation is applied directly to the roots of the fertigation crops.
Proper fertilization is essential to reduce nutrient loss and increase crop production. The amount of water required to evaporate inside the greenhouse can be predicted by the amount of water required.
The efficiency of normal irrigation is 33%, that of sprinkler irrigation is 7 5% and that of sprinkler irrigation is 90 - 95%. Completely water-soluble nutrients can be provided by fertigation.
However, nitrogen and potash are best suited for plants as they are readily available. The fermentation of the elements does not cause clogging problems as the water in Kerala is acidic. All soluble elements are suitable for fertigation.
Therefore, when the focus is mainly pherttigesan valannalil use of nitrogen fertilizer, the price and other elements contained in it, and the need for .pherttigesanu (N) sources of ammonium nitrate, calcium nitrate, ammonium sulfate, urea, potassium nitrate and ksarattinre (K) shall be the main source of Po Tasyam chloride, potassium nitrate, potassium sulfate and a. Phosphorus (Future)
Diluted phosphoric acid or mono ammonium phosphate may be given for fertigation. Rock phosphate and super phosphate can be applied in bedding.
The total amount of phosphorus in the soil in Kerala is generally high. Phosphorus (Phosphorus) fertilizer should be applied on the basis of the amount of water soluble / available phosphorus available to the plant.
Based on the above facts, the method of temporary fertigation has been prepared. (See table) The schedule provided herein is not the same for all policy houses.
Depending on the nutrient status of the soil and the seed sown in the different poly houses, fertilization can be done only on the basis of expert advice.
