Diving Deep into the Process of Fertigation and Chemigation

With rising population all over the globe, agriculture plays a vital role in fulfilling the needs of the people, in terms of food crops and cash crops Fertigation and Chemigation, both are a part of contemporary commercial horticulture and agriculture practices. Both techniques prove their worth for cash crops in gold, which are agrarian crops grown for selling for profit. Both of these processes are environment friendly and also cost-effective at the same time. This blog will help you to understand both the processes, and why both the practices are important for agriculture.

What is Fertigation?

Talking about fertigation, it is the technique of supplying fertilizers with the help of an irrigation system. In this procedure, fertilizers are supplied to the roots of the plants with the help of an injection. Fertigation is put to use for avoiding the imbalance of fertilizers. This process is a part of more innovative technology called Chemigation. The most significant characteristic in fertigation is that the fertilizer injected should be balancing to the yield of crop.

Fertigation is also known by the name of micro irrigation. More than fifty nations all over the world use micro irrigation. In India, this technique is employed in over 10 lakh hectares of land.

There are two types of injection methods used under fertigation, venturi injection and pump injection.

In the former, fertilizers are injected into the root of a plant by generating vacuum. Venturi is used for vacuum creation. This device makes use of water as a motive fluid. The movement of motive fluid through the Venturi makes vacuum encouraging the roots for absorbing fertilizers.

The method of injecting a pulsating stream of liquid with the use of a reciprocating action is known as pump injection. Water or electricity itself powers the engine for ensuring adequate pressure for injection. The chemicals, which are to be injected should be water-soluble soluble and compatible.

Advantages of Fertigation

The main advantages of fertigation are:

• Optimum supply of macro and micro nutrients• Control on irrigation systems• Quality of the crop is better• Better crop yield.

Understanding the Technique of Chemigation

It is a cutting-edge version of fertigation. This makes use of an irrigation system for the distribution of agrichemicals and water as well as pesticides to cropland. In the practice of chemigation, substances that are injected consist of algaecides, fungicides, herbicides, and insecticides. Also, in some cases, soil penetrants, fumigants and pH control chemicals are also delivered through an injection into the root of the plant. Chemigation has a major role to play in decreasing the risks related to the contamination of ground-water and run-off of agro-chemicals.

Summing Up the Scene

It is because of the increasing population of the world, and the risk of water scarcity and growing demand for food, the demand for fertigation and chemigation processes is on the rise. It will reach a value of USD 21,434.8 million, by the end of this decade.
