FARM LAND SHAPING FOR IRRIGATION

ABSTRACT : The mainly practical and environmentally way of creating irrigation assets in the coastal area is through harvesting of excess rain water that goes waste as runoff into the sea. It can be done effectively through suitable shaping of the farm land, which involves in modifying the surface of the farm land for harvesting of excess rain water as well as making the land surface suitably shaped for adoption of improved cultivation of diversified crops. The most important intention of these land shaping is for creating irrigation resources through harvesting excess rain water, diversification and multiple crop cultivation encompassing the year Employing innovative land management practices will not only serve the land degradation concerns but also enable to harvest rainwater and diversification of agriculture. A comprehensive study conducted on fertility indicated that the cutting in slope group of 1.5 to 3 % reduced nitrogen content appreciably. It is also seen that in the first two years removal of surface soil created a problem in zinc deficiency. It is therefore, necessary to augment fertility with a higher dose to tune of 1.25 times greater than usual dose.
