Earthworm is life of soils. It regulates soils productivity, humidity and concentration of water, oxygen, minerals, temperature and pH. The life of earthworm is getting destroyed by application of artificial insecticides, pesticides, herbicides, fertilizers, various types of wastes and acid rain. These killer substances change physical, chemical and biological properties of soils and generate corrosive atmosphere for earthworm. These pollutants change the concentration of natural minerals which are present in soils by increasing the acidic character of soils. The acidic soils develop microbiological corrosion cell with earthworm and it oxidize carbohydrate, protein and fat into CO2, H2O, NH3, glycerol and organic acid. Corrosion reaction increases the temperatures of soils and finally kill earthworm. Heavy metals and gaseous pollutants come into soil by different medium which produce corrosive effect for earthworm. Pyrite ores of industrial area enter into soil to form acid that acid is corroding earthworm. These foreign materials contaminate soil and reduce the fertility of soil. Aloe Vera juice is applied to control the pH values of soils and protect the life of earthworm. The experimental work shows that Aloe Vera has capability to control the physical, chemical and biological parameters of soils and it also enhances the fertility and productivity of soil and protects the life of earthworm by corrosive pollutants. For this work soil samples are taken from the coal area of Jhariya district (in Dhanbad), steel plant area Chas in Bokaro district, urban area of Chak Beyriya in district of Patna and village area of Fulwariy-Tajpur in district of Chapra.
