Fertigation is a new farming technology that connects irrigation and fertilization. Fertigation technology uses a pressure system, to combine solvent solid or liquid fertilizers with irrigation water, according to the nutritional needs of the crop, and through the help of a controllable pipeline system.
The fertilizer has been integrated into the irrigation water, it then evenly, regularly, and quantitatively waters the growth and developmental root zone of the crops, through the pipeline and the drippers. Advanced greenhouse fertigation systems & technology allows the root-soil to remain loose and to maintain the appropriate water content.
It also allows farmers to design the fertigation system according to the characteristics of different vegetables, the soil environment, the current nutritional state of the crops, the water demand of vegetables in different growth periods, and fertilization cycles so that the crops receive a proportional amount of water and nutrition regularly and quantitatively.
This technology is suitable for fixed water sources such as wells and reservoirs. It should also be promoted and applied in areas that have good water quality, that are in line with micro-irrigation requirements, and that have already set up or had the conditions to set up micro-irrigation facilities. It is mainly applicable to agriculture, horticulture, cultivation of large-scale industrial crops such as cotton, as well as other economically viable crops.
Fertigation systems save 50-70% more fertilizer than conventional fertilization systems; also, it greatly reduces the water pollution problems that arise from excessive use of fertilizers in agriculture and horticulture.
