India is a semi-arid country. Certain places receive the maximum rainfall in the world, while other places have the driest spell. Irrigation is one of the biggest concerns in our country where sometimes there is an overflow of water, while other times there is non-availability of water. Farm produce on the other hand needs a continuous supply of water to the roots.
This irregular water supply problem leads to crop failure and it hampers the country in several ways. Farmers are the backbone of the country and work hard to have better produce but the irregularity of rains create a lot of problems. With the current increase in global warming, irregularity has increased a lot.
We propose a hydrogel that can hold water up to 1000 times of its initial capacity and is salt tolerant for the high salty soil in India. It is one of the best-achieved water holding capacities. It essentially holds water where there is plenty of water available and releases it slowly.
The hydrogel can decrease the requirement of water in irrigation by 30% as well as giving a better yield from the crop by 10-15 % depending on different crops grown. In areas of water scarcity and the water-intensive cropping cycle, it is very beneficial. The hydrogel once implemented in a farm is capable of giving good results for 3 years and hence saves a lot of cost for the farmers in India.
