Animal dung in the form of dried cakes is also burned for domestic purposes. Animal dung contains vital nutrients. If burnt directly they produce a lot of smoke leading to air pollution. Instead animal dung can be converted into biogas which is a clean fuel. The residue which is rich i..

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 free nitrogen. Thus the process of converting atmospheric n..

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.

It is obtained by heating sugar in the absence of air. Sugar charcoal is the purest form of amorphous carbon. Sugar charcoal becomes activated charcoal when it is powdered to particle size of about 5 µ and heated at about 1000 K in vacuum. Activated charc..

Biofertilizers - Any living organism supplying plant nutrients directly or indirectly is regarded as biofertilizer. They are not synthetically manufactured in factory. Many organisms with a potentiality to supply plant nutrients - have been recognised. Use of biofertilizers has many advantages. The..
