What is Fertigation? What are the Pros and Cons?

New technologies in irrigation methods have brought some conveniences and innovations in the application of fertilizers. For example, drip irrigation system has become an indispensable part of modern agricultural production. This system has provided the opportunity for the fertilisers to be administered with irrigation water. In this so-called “fertigation” method, water-soluble fertilizers are delivered to fruit trees by means of a fertilizer tank installed into the irrigation system. Besides fertilizers; hersicides, insecticides, fungicides and growth regulators can also be given via the fertigation technique.

Pros of fertigation include;

Irrigation and fertilizing work is reduced to a minimum. Less water and fertilizer are used. Since unnecessary water and fertilizer are not used, environmental pollution is prevented by avoiding deep infiltration and nutrient washing. The rate of conversion of fertilizer and water into yield is higher. It allows growers to apply fertilizer whenever and however they want. Thus, any nutrient deficiency can be immediately intervened. With acid application, the irrigation system is protected and the pH of the solution is adjusted so that the nutrients are utilized at the highest level.

Cons of fertigation include;

Installation and efficient operation of the system requires know-how and command of the technique. Therefore, technical support should be sought in order to achieve desired result. The initial installation cost of the system is somewhat high. However, return of investment is rather quick. Fertilizers often cause corrosion in metal parts. This problem is eliminated when corrosion resistant materials are used, especially in fertilizer tanks and other equipment that comes into contact with fertilizer.
