  Sustainable scientific methods of farming

Sustainable scientific methods of farming:

Sustainable agriculture involves scientific methods of farming which use renewable resources, rise in yield, avoidance of manmade complex substances termed as Xenobiotics that are employed as insecticides and pesticides which cause pollution to soil and environment. Plant tissue biotechnology and culture as well play a main role in this.

50 ranges of rice and 20 varieties in wheat have been developed in China via using these new methods without damaging the environment. New disease opposed to virus free plants and stress resistant plants are successfully generated. Likewise, transfer of nif (nitrogen fixing) gene to non- leguminous crops will enhance higher yield. Biotechnology and tissue culture that contributed more to sustainable agriculture through giving bio fertilizer, bio pesticides, disease and insect resistant varieties by formation of single cell protein, transgenic crops, production of valuable pharmaceutical products and herbal drugs (Ginseng Vinca, Emetine from Cephalis) through using micro propagation technique.

To finish Sustainable agriculture is an eco-friendly farming system related with production of food when keeping on biophysical resources involving soil, water, and biota along with no adverse influences on the environment. Thus it should

1. Maintain or enhance the production of clean food.
2. Maintain or enhance the quality of landscape that includes soil, water, biota and aesthetics
3. Have minimal influence on the environment.
4. Be economically viable and.
5. Be acceptable to society.

Sustainable farming employs eco-friendly fertilizers, and pesticides and modern technologies, like improved seed, new equipments for low- tillage practices, pest control by using biological control principles and weed control that relies upon crop rotations. Sustainable farms attempt to use wind/solar energy in place of purchased energy and use organic manure and nitrogen fixing legumes like green manures to keep soil fertility thus reducing supply from outside farms. The importance is on keeping the environment without effecting the pollution.

Organic farming is described as production systems that avoid the make use of synthetic growth regulators, fertilizers, pesticides, and livestock feed additives. It relies on crop rotation, legumes, green manures, crop residues, animal manures, and off-farm organic wastes by using mechanical cultivation, biological pest control (bio pesticides) to keep soil productivity and to provide plant nutrients and to control insects, pests and weeds.
