Nutrient losses in soil due to erosion
Narendar Kumar Meena, Ramavtar Gautam, Prabhat Tiwari and Prashant Sharma
The nutrient loss is closely related to erosion. The amount of individual nutrient deteriorates from soil by any factor this nutrient loss use full for plant and crop and affect the water bodies. Soil nutrient lost mainly through the runoff many nutrients are dissolving in rain water or lost. The rate of soil loss is 16.4tonnes/hectare every year, (CSWCTRI), Dehradun. Mainly N2,
Ca, P, Mg, K and organic matter can be lost from agriculture land through soil erosion. Manure and fertilizer can help to protect against nutrient loss low through erosion or runoff. These losses are affected by soil type, vegetative cover and land slope or fertility. Where soil are highly erodible, conservation tillage can reduce soil erosion and runoff, resulting in less surface loss of nitrogen. Soil erosion means detachment, transformation and deposition. Erosion is detachment of soil particle from one place to another place by the action of wind and water. Nutrient loss due to erosion is very harmful effect for crop production reducing regularly or arable land convert in barren land. Annual soil loss of India is 16 tonâ€™s/hectare when permissible limit is 12tonâ€™s/hectare. Water and wind eroded area in India is 93.68 Mha and 9.48 Mha (NBSS & LUP). Active soil erosion occurs due to floods over 140mha of land resulting loss of 6000 MT of fertile soils containing 5.5MT of NPK. Mainly two type of erosion wind and water erosion. Wind erosion mainly found in North-west part of India and water erosion mostly in hilly areas of country. Wind erosion is mainly three typeâ€™s saltation, suspension, or surface creep in witch suspension is more hazards. Water erosion types are splash, sheet, gully erosion in which sheet erosion is more hazards in which fine clay partials and soluble nutrients are remove with water.
