Specifically, this research examines the consequences of increases in fertilizer use on soil fertility, maize yields, nitrogen gas emissions and nitrogen leaching losses the research relied on a range of instruments and techniques, including a weather station, lysimeters, and handheld nitrate meters. Many people use fertilizers to give extra life to their lawn and garden, but few people consider the potential drawbacks of these fertilizers in an effort to be as environmentally conscious as possible, it is important to consider the potentially harmful effects of fertilizers as well as the benefits.

The use of fertilizers has risen as a consequence, up 575% over the period 1970-1986 and without any gain in crop yields loss of n-p-k from an average erosion of 20 t/ha/yr represents an annual economic loss of us$242 million in nutrients.

The organic fertilizer and liquid fertilizer have higher ec values, which may increase soil ec and thus affect plant growth after the fertilizers are applied to the land table 1 effects of different nitrogen fertilizer treatments on soil properties. The common use fertilizers is the main reason behind the loss of productivity of the earth, which in turn must be artificially enhanced with growing amounts of chemical products inside this vicious circle the soil is loosing its natural properties which must be constantly compensated by an artificial improvement of the efficiency of.

More efforts to increase the efficiency of nitrogen fertilizer use through modifications or use of inhibitors of biological processes as well as better management of rates, timing, and incorporation are needed to ensure increased food production while conserving natural resources.
