Effect of Fertilizers On The Environment One of the biggest challenges of the modern agriculture is to provide food for the world's increasing population, while minimizing the strain on the environment. Fertilizers misuse can have adverse effects on the environment, such as: Contamination of groundwater and surface-water Soil structure damage and increased soil erosion Polluted food-products Air pollution Groundwater Contamination Fertilizers accumulated in the soil, may leach into its lower layers and eventually reach the groundwater. The rate, in which the excess nutrients leach, depends on several factors, such as soil type, the nutrient electric charge, the nutrient concentration etc.   Nitrates (NO3), being highly soluble, have the highest potential of reaching groundwater. Leaching of Nitrate from agricultural fields can increase Nitrate concentration in the groundwater to levels unacceptable for drinking water quality. Unused fertilizers can also be washed to lakes, rivers and reservoirs and lead to growth of algae and weeds. Salinity Buildup And Damage To Soil Structure When accumulated in soil, excess fertilizers increase salinity build-up and reduce soil fertility. Subsequently, soil structure is damaged and soil erosion is promoted.   Smart! contributes to a greener planet, promoting compliance with modern standards for environmental protection and helps growers to use fertilizers accurately and efficiently, preventing over-fertilization and its negative impact on the environment.
