Fertigation is a method of fertilizer application in which fertilizer is incorporated within the irrigation water by the drip system. In this system, fertilizer solution is distributed evenly in irrigation. The availability of nutrients is very high therefore the efficiency is more.

Water-soluble fertilizers are fertilizers that can be dissolved in water and added or leached out of the soil easily. With water-soluble fertilizers, it is easy to control the precise amount of nutrients available to plants. Water-soluble fertilizers are best applied through micro-irrigation systems.

Soluble fertilizers usually have N-P-K numbers listed on their label. The N is for nitrogen, the P is for phosphorus and the K is for potassium or potash. Of the 16 (12 of which are contained in water-soluble fertilizers) known elements necessary for plant life, N-P-K, are the three that are of the most important and always listed on water-soluble fertilizers, in that order. Following N-P-K, calcium(Ca) and magnesium(Mg) are the two, second most important nutrients listed on the label. The rest, iron(Fe), sulfur(S), manganese(Mn), boron(B), molybdenum(Mb), zinc(Zn) and copper(Cu) are trace elements or micro-nutrients.

Water-soluble fertilizers are efficiently absorbed by plants.

25-30% of the recommended dose of fertilizer can be reduced by using WSF.

Essential nutrients can be applied uniformly to each and every plant even on daily basis.

Applicable through irrigation water as well as a foliar spray for quick absorption by the plant.

As it is applied to crop requirements, it reduces the accumulation of salts in the soil.
