Abstract: A process of improving the nutrients of sub soil by digging a portion of land called as trench to a width and length in the same land to receive the volume of the soil required to put the bed on the complete land as the top layer. In one embodiment, the present invention relates to a novel process of improving soil fertility leading to high yields of cereals traditionally grown crop like rice in said agri-zone. In another embodiment, it describes the high yield production of non-traditional cereal crop like wheat. Both the system production warrants low or no inputs like chemical based fertilizers and pesticides. Higher yields coupled with high nutritional levels as a result of restoration of fertility levels in depleted soils are main results of the innovative process.
