Abstract
Fertilizers have long been seen as an important means of producing the food needed by the population as they replace the nutrients removed by crops and maintain soil fertility. However, the environmental implications of this cause growing concern as evidence increases that application of agrochemicals and fertilizers is reducing the quality of water, particularly in terms of the nitrate content in drinking water. In recent years a significant upward trend in the nitrate content has been recorded, especially in groundwater resources underlying arable land (Ronen et al. 1984). Moreover, recent reports have indicated that the concentration within aquifers can be expected to intensify as a result of the continued accumulation of nitrogen in the soil profile (Jollans 1985, Ronen and Magaritz 1985).
