For many years, the use of fertilizers to enhance crop yields in vegetables and fruits have been used extensively in the US farming industry. However, these same fertilizers can at times not stay on the farming land and “run-off” the land into streams and rivers. The run-off of these same chemicals happens when the fields are exposed to heavy rains. How would you minimize or even prevent the run-off fertilizers into our neighboring water bodies?

Answer:
The efficiency of fertilizer nitrogen can be increased and losses reduced, by matching supply with crop demand, optimizing split application schemes, changing the form to suit the conditions, and use of slow-release fertilizers and inhibitors.Fertilizers replace the nutrients that crops remove from the soil. ... Provide nutrients not available in the soil. Replace nutrients removed at harvest. Balance nutrients for better produce quality and higher yield.Some of the harm chemical fertilizers may cause include waterway pollution, chemical burn to crops, increased air pollution, acidification of the soil and mineral depletion of the soil.Fertilizers provide crops with nutrients like potassium, phosphorus, and nitrogen, which allow crops to grow bigger, faster, and to produce more food. ... To grow, plants require nitrogen compounds from the soil, which can be produced naturally or be provided by fertilizers.Use only the recommended amount of fertilizer. Be sure your spreader is properly calibrated to deliver the appropriate amount. Also be sure to apply fertilizer at the appropriate times during the year. Do not apply fertilizer near ponds, wells, or waterways. The usage of organic fertilizers results in the discharge of nitrate, potassium and phosphates that pollute the water. The contamination of groundwater occurs as a result of leaching due to nitrate. The ground and surface waters are infested with heavy metals, whose concentration poses a threat to humans and animals.Fertilizer contains salts, which draw moisture out of plants. When you apply excess fertilizer to plants, the result is yellow or brown discoloration and root damage. Fertilizer burn symptoms may appear within a day or two, or it may take a couple of weeks if you use a slow-release fertilizer.
