Agro - chemicals and their effects Green Revolution was an intensive plan of the 1960s to increase crop yields in developing countries by introducing higher-yielding strains of plant and new fertilizers. The scheme began in Mexico in the 1940s, and was successfully introduced in parts of India, se Asia, the Middle East, and Latin America. Non-target organisms include all organisms except for the pest to be controlled. Examples of non-target organisms would be mammals, fish, birds, reptiles and other insects. Use of inorganic fertilizers and pesticides has increased manifold for enhancing crop production, in the wake of green revolution. Pesticides, Herbicides, Fungicides.,etc are being increasingly used. These are also very toxic to non - target organisms, that are important components of the soil ecosystem.
Green revolution in India The Green Revolution in India refers to a period of time when agriculture in India changea to an industrial system aue to the adoption of modern methods and technology such as HYV seeds tractors, irrigation facilities, pesticides, fertilizers etc Green revolution was started by Norman Borlaug. The key leadership role played by the Indian agricultural scientist M.S.Swaminathan together with many others including GS Kalkat, M.S.Swaminathan earned him the popularly used title 'Father of Green Revolution of India'. The green revolution allowed developing countries, like India, to try to overcome poor agricultural productivity. Within Inaia, this startea in the early 1960s and led to an increase in food grain production, especially in Punjab, Haryana and Uttar pradesh (especially Western UP) during the early phase . The main development was higher-yielding varieties of Wheat,2l for developing rust resistant strains ofwheat. 121
So can they undergo Bio magnification??? Bio magnification, also known as bio amplification or biological magnification, is the increasing concentration of a substance, such as o toxic chemical, in the tissues of tolerant organisms at successively higher levels in a food chain. For example, spraying a marsh to control mosquitoes will cause trace amounts of DDT to accumulate in the cells of microscopic aquatic organisms, the plankton, in the marsh. In feeding on the plankton, filter- feeders, like clams and some fish, harvest DDT as well as food.
Let's know about Ramesh Chandra Dagar, a farmer in Sonipat, Haryana. Ramesh Chandra Dagar???
He includes bee - keeping, dairy management, water harvesting, composting and agriculture in a chain of processes, which support each other and allow an extremely economical and sustainable venture. He helped on the practice of integrated organic farming as he was enthusiastic about spreading this information. Dagar has created the Haryana Kisan Welfare Club, with a current membership of 5000 farmers.
Effective methods??? Integrated organic farming is a cyclical, zero waste procedure, where waste products from one process are cycled in as nutrients for other processes. This allows the maximum utilisation of resource and increases the efficiency of production.
Other alternatives, Use of cattle excreata (dung) as manure instead of chemical fertilizers for crops. Crop waste is used to create compost, which can be used as a natural fertilizer or can be used to generate natural gas for satisfying the energy needs of the farm
