Role of Injectors in Drip Irrigation
Date: 21-04-2022What is Drip Irrigation?
The drip Irrigation is the artificial application of water as per the daily need of the plant directly to the plant root zone. Here drip irrigation is a low pressure operation usually having operating pressure of 1 Kg/cm2. Amongst the few brands famous for Drip Irrigation System Manufacturers & Suppliers in India, the Kothari group stands tall for its best quality and highly efficient drip irrigation system.
Need of Injector
Since the plant is a living thing, it needs air, light, water & nutrients. The air & light are natural & we are using drip system for water application. For supplying nutrients, the role of injector is very important in drip system and this needs to be taken into consideration by the drip irrigation system manufacturers.
In order to remove physical and biological impurities, it is also necessary to use the filtration For removing chemical impurities & biological impurities, we need acid treatment. Here, the Injectors play the major role in acid treatment.
