Fertigation means applying fertilizers along with irrigation water. All the three major nutrients like nitrogen, phosphorus and potassium and micro nutrients needed for the plants can be given through fertigation. The Fertilizer Use Efficiency increases when the fertilizers are applied through fertigation. In order to carry out the fertigation in a proper and precise manner, the venturi, fertilizer tank and fertilizer injection pump are used. Most of the conventional fertilizers are soluble in water, but to achieve better efficiency water soluble fertilizers are also used in fertigation.
