Agriculture and the Nitrogen Cycle Essay

Agriculture is an burning(prenominal) industry that provides food for human consumption. The decrease of land available for horticulture coupled with the adjoin of human population has required that agricultural lands increase their output. This was achieved through the habit of improved crop varieties, more productive livestock, violate weed and pest control and the change magnitude use of fertilizers, specifically normality fertilizers which has linearly increased to 1. 2 Mt in the 1980s. However, farming similarly affects the environment.Increases in phosphorus and nitrate contents of water lead to increased biological activity and large concentrations of nitrate in drinking water create health hazards. J. K. R. Gasser studied the normality cycles in agriculture and in pee the results in his article Agricultural Productivity and the Nitrogen Cycle. Gasser (1982) explained that northward is emitted from the nation or from animal effluents as ammonia, nitrous oxide or N 2. Considerable amounts of nitrogen are also recycled directly as animal urine and feces. The antecede crops in agricultural lands also affect the amount of nitrogen released for the flowing crops.However, Gasser (1982) explained that no arable system provides enough nitrogen for the maximum achievement of crops such that additional nitrogen must be added in the form of fertilizers. Gasser (1982) reported that there is no evidence supporting that the increased use of nitrogen fertilizer also increases the total amount of nitrogen in soil-plant system. He stated that little of the nitrogen in circulation will bet directly in the atmosphere or groundwaters, most will leave of absence the agricultural system after one or more changes or subsidiary cycles (Gasser, 1982, 313).Gasser (1982) concluded that the losses from the system must be at least as large as the known inputs. He persuaded to evaluate the movement of nitrogen, the understanding of which would allow the losses from agricultural system to be minimized improving the utilization of nitrogen in farming and cut back its effects on the atmosphere and water.Reference Gasser, J.
