Repeated use of chemical fertilizers leads to soil salinization due to a decrease in organic matter.
It leads to a risk to soil life, accumulation of mineral salts, and long-term soil degradation.
The seepage of chemicals used in fertilizer manufacturing through the soil leads to the pollution of groundwater and waterbodies.
The gases emitted from nitrogen fertilizers during their decomposition in the soil, as well as those emitted from chemical fertilizer factories, cause global warming, acid rain, and ozone layer destruction.
Increase the alkalinity and salinity of the soil, which causes the death of beneficial microorganisms for the soil and plant, and thus a decrease in soil fertility.
