-Air pollutants e.g. sulphur IV oxide fumes form sulphuric acid with rain water. The acid
rain alters soil pH therefore affecting plants that cannot tolerate acidic soil
- most aerosols sprayed to control pests and diseases precipitate in the soil and are taken up
by plants which make its concentration many times higher, increasing the toxicity in the
plants which absorb them
-petroleum products due to spillage by oil tankers making it impossible for plant roots to
obtain oxygen in oil saturated soils, therefore plants are killed
- agrochemicals and inorganic fertilizers contain heavy metals that are not used up by
plants and eventually soil microorganisms cannot inhabit the soils
- organic matter slows down, life ceases and soil becomes exhausted
- community, household wastes and industrial wastes disposal is a major problem in big
towns and cities. commodities packaged in metal tins, rubber, plastic containers, scrap
metal, glass bottles, different types of paper are nuisance to the environment, rendering it
useless for agricultural purposes
