How are inorganic fertilizers bad for the environment?
●Many types of inorganic fertilizers are highly acidic, which in turn often increases the acidity of the soil, thereby reducing beneficial organisms and stunting plant growth. By upsetting this natural ecosystem, long-term use of synthetic fertilizer can eventually lead to a chemical imbalance in the recipient plants.
How does fertilizer leach out of the soil?
Plants have the capacity to absorb only a given level of nutrition at a time leaving the rest of the fertilizer to leach. Leaching is not only hazardous to groundwater sources but also to the health of subsoil where these chemicals react with clay to create hard layers of soil known as hardpan.
How are fertilizers used to increase plant growth?
Chemical fertilizers or inorganic fertilizers are manmade soil enhancers used to raise the level of nutrients found in soil. The natural nutrients found in the soil essential to plant growth, such as nitrogen, phosphorus and potassium, are manufactured synthetically from inorganic material and applied to soil in the form of chemical fertilizers.
