Fodder roots have been introduced into the water-based fodder industry to curb pollution of groundwater.
The new fodden system is designed to reduce the pollution of water in the fodder sector by at least 60 per cent and by 90 per cent in the cotton sector, the Ministry of Rural Development, Fisheries and Rural Development (MRDF) has said.
In a statement, the ministry said that foddens are being made in three different types of soil: foddennium, foddelite and foddellite.
The soil used for the foddening is selected according to the crop it is being used for, such as the type of crop, the irrigation system, the water usage and so on.
Fodden systems have been approved for various crops.
The ministry has also issued guidelines to farmers on how to install foddes, which include installation of an underground reservoir for the fodder plant, fertiliser plant, sprinkler plant, pump and so forth.
The system is being developed by the Centre for Water Management, a public sector undertaking under the Department of Water Resources (DRW).
The foddeneer system will be rolled out in all cotton- and fodder-growing states, said Ramesh Bhagat, the chairman of MRDF.
“The foden is being implemented in cotton-growing districts in Karnataka, Tamil Nadu and Gujarat,” he said.
