Dumping of solid wastes / empty containers scrap metals, glass bottles, plastic containers; these lenders the environment to be useless for agricultural purposes;
Excessive use of inorganic fertilizer on the farm; lowers the organic content of the soil reducing the water retention ability; decreases organic matter content making the soil uninhabitable by micro and macro organisms in the soil; making the soil to reduce soil fertility;
Excessive use of pesticides; this kills intended beneficial soil organisms both micro and macro organisms resulting to reduction in soil fertility;
Agrochemicals like pesticides / fungicides / herbicides alters the soil pH; resulting in poor plant growth;
Continuous use of chemicals in the farms / aerosols / agrochemicals precipitate in the soil and are taken up by plants; their concentration build up in the plants increasing to toxic levels;
Heavy metals contained in agrochemicals in the soil are not used by plants hence accumulating in the soil; and eventually make it inhabitable by micro-organisms;
Air pollutant like sulphur (IV) oxide and nitrogen (IV) oxide forms acid rain; the acid rain alters the soil pH causing poor growth of plants;
Radioactive wastes dumped in the soil; cause death of micro-organisms in the soil;
Oil effluent in the soil; they kill soil organisms / prevent root from taking oxygen and absorption of water;
