reduced nitrogen fixation in soil due to soil pollution

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..

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..

Soil Ecological Imbalance - Soil ecology is the study of life in soil in harmony with abiotic factors like air, soil particles, carbonaceous materials etc. In its natural condition, soil has its own equilibrium featured by delicate balance between m..

>Out of 142 million hectares of land, nearly 43 million hectares of land is put to use more rigorously to grow two crops in a year. Remaining land can also be used to grow more crops. But, adverse rainfall distribution will not permit crops two crops in all the area. N atural restoration ..

During rains, when lightning strikes, nitrogen and oxygen of the atmosphere combine to form nitric oxide. This is further oxidized to nitrogen dioxide in the presence of excess of air. Nitrogen dioxide combines with rainwater in presence of oxygen to produce nitric ac..

Different types of crops with differing requirements are grown alternatively in the same soil. Leguminous crops such as pulses, peas, beans, grams, groundnuts etc are sown after the cereal crops such as wheat and maize etc. Wheat crop takes a great amount of nitrogen from the h..

Soil is the medium for plant growth, it provides anchorage to plants. Soil provides nutrients, both major and minor, to plants for their growth and development. Thus, it circulates the nutrients into biological system by means of mineral weathering. Soil harbou..

Environmental Pollution - 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 ..

Nitrogen Cycle - Nitrogen is an essential constituent of animal and plant matter as it forms proteins, which are the building blocks of life. The ultimate source of nitrogen is atmospheric nitrogen but neither plants nor animals are capable of assimilating fr..

Nitrogen and oxygen forms five oxides of nitrogen. Out of which only three, namely; nitrogen dioxide (NO 2 ), nitric oxide (NO) and nitrous oxide (N 2 O) are present in the atmosphere in significant amounts. Of these only NO and NO 2..
