Organic matter forms humus. It is essential for crop production because it makes the soil fertile. matter Organic has the following advantages: (i) It improves soil structure by forming soil crumbs. (ii) It increases water holding capacity of sandy soils. (iii) It improves aeration of clayey soils.Read more

(i) It improves soil structure by forming soil crumbs.
(ii) It increases water holding capacity of sandy soils.
(iii) It improves aeration of clayey soils.
(iv) During its decomposition, it liberates minerals (inorganic molecules) which enrich the soil.
(v) Biochemicals present in decaying organic matter improve growth of crop plants.
GM or genetically modified crop is the one which has been developed through introduction of some specific genes from other sources, e.g., insect resistant Bt cotton (being grown in India), vitamin A rich Golden rice.

Effective practices towards conserving forests and wildlife are as mentioned below:
(i) The inhabitants of five villages in the Alwar district of Rajasthan have declared 1200 hectares of forest as the Bhairodev Dakav ‘sonchuri’, declaring their own set of rules and regulations. They do not allow hunting and are protecting the wildlife against any outside encroachments.
(ii) In tribal areas ‘Sacred Groves’ have been left untouched by the local people and any interference with them is banned.
(iii) In and around Bishnoi villages in Rajasthan herds of black buck, nilgai and peacocks can be seen as an integral part of the community and nobody harms them.

Various movements have been started against deforestation in different parts of the country. Some the of these movements are as follows:
(l) Chipko Movement: It was started in the Himalayan region by Sunder Lal Bahuguna and successfully resisted deforestation. It has shown that community can play an important role in afforestation with indigenous species. Attempts are now being made to revive the traditional conservation methods or to develop new methods of ecological farming.
(ii) Beej Bachao Andolan in Tehri and Navdanya have shown that adequate levels of diversified crop production without the use of synthetic chemicals are possible and economically viable.

The forests are classified under the following categories:
(i) Reserved Forests: These forests are permanently earmarked either for production of timber or other forest produce. Right of grazing and cultivation is seldom allowed in these forests. In India more than half of the total forest land has been declared reserved forests. These forests are regarded as the most valuable as far as the conservation of forest and wildlife resources are concerned.
(ii) Protected Forests: Right of grazing and cultivation are allowed subject to few restrictions. One-third of forest area consists of protected forests. These forests are protected from further depletion.
(iii) Unclassed Forests: These forests consist of inaccessible forests or unoccupied forests. They belong to both government and private individuals and communities.
