soil pollution effects reduces soil fetility

Agricultural - Reduced soil fertility Reduced nitrogen fixation Increased erodibility Larger loss of soil and nutrients Deposition of silt in tanks and reservoirs Reduced crop yield Imbalance in soil fauna and flo..

Soil is the thin layer of organic and inorganic materials that covers the Earth's rocky surface. The organic portion, which is derived from the decayed remains of plants and animals, is concentrated in the dark uppermost topsoil. The inorganic portion made up of rock fragments, was formed..

The following steps have been suggested to control soil pollution. To help prevent soil erosion, we can limit construction in sensitive area. In general we would need less fertilizer and fewer pesticides if we could all adopt the three R's: Reduce, Reuse, an..

. Its sources are sewage that includes organic matter, industries, agricultural chemicals, oil spill, etc. The major pollutants are the organic matter of the sewer, metallic substances and other inorgaic chemicals from the industries, hot water, oil, inorganic fertilizers and pesticides. ..

The substances/species produced either by a natural source or by human activity, which cause an adverse effect on the environment on being in excess of a desirable limit, are termed as pollutants. Some common examples of pollutants are carbon monoxide, sulphur dioxide,..

>The dangerous effects of pollution are governed by factors like concentration of pollutant exposure to pollutant area / section of population affected type of pollutant and dangers caused by them process of degradation / metabolism of pollutants Ea..

Applying bio-fertilizers and manures can reduce chemical fertilizer and pesticide use. Biological methods of pest control can also reduce the use of pesticides and thereby minimize soil pollution..

(based on soil pH, available water, temperature). As there are large number of varying types of soils in varying climatic situations being used to grow varieties of crops with differing abilities to make use available nutrients, the expressions of crops in terms of their yield p..

Forests are the invaluable wealth of a country and a renewable natural resource. They are beneficial to man in several ways. a) Forests provide fuel wood, timber, paper, bamboo, rayon, cane etc. b) Forests also provide a large number of important products such as essential oils, tannins, resins, g..

Natural resources that are limited in nature and are liable to be degraded in quantity and quality by human activities are exhaustible natural resources. Examples are forests, soil, wild animals, minerals, fossil fuels etc. The understanding of the environment and its proper conservation..
