Current situation of agriculture

DE

India and other countries

Dr.Ashok K. Panigrahi and Misra Mrs.Kusum


agriculture is more than just farming without chemical fertilizers or synthetic pesticides and is rather a holistic approach to the system of agriculture, restores, maintains and improves the economic sustainability and ecological balance of production of non-toxic, healthy and tasty food or medicine or dye with natural fragrance and color.

In today’s world the most, since organic producers believe in biodiversity, avoid genetically modified, whether plants or seeds or plants or animals. Do not use chemicals or soil fertility or pest control, no chemicals, either for growth or protection, except drugs that even if the situation is very bad and out of control.


OVERVIEW

Organic farming is now practiced in over 100 countries. The harmful effects of agrochemicals to the last decades, the minds of consumers in different countries, who are now ready organic foods or substances bye now changed with a high premium.

makers are now promoting organic agriculture for various reasons such as soil health, support the rural economy and a better environment. The global organic area is estimated at 26 million hectares with 61 standards and 364

CA.


world organic market is estimated at U.S. $ 26,000,000,000th


certified organic surfaces in India is estimated at 2.5 million hectares but the area is much higher uncertified.


historical perspective

Organic farming is practiced in India since the beginning of agriculture in this country and was introduced more than those to the green revolution in this country in the mid-sixties.


A brief mention of organic farming in ancient literature, as the Rigveda, the Ramayana, the Mahabharata and Kautilya Arthshastra etc.

Sir Albert Howard was the first farmer in the industry that India was launched by the British to Indian farmers to teach in the use of agrochemicals, but he ended up in the teaching of agriculture among Indian farmers, developed the Indore process and went continuing to build the bridge between the symbiotic fungus of humus in the soil and plant sap through mycorrhizal associations. He writes in his, a farm will: “Since the industrial revolution in agriculture has become unbalanced, the country is in turmoil, get all kinds of illnesses, the nature spent removing the soil by erosion.”

6 Rigveda 2.500 to 1.500 BC, green manures, use of fertilizers, goat, sheep, cow, etc.

widespread use of chemicals in agriculture in India

Nobel laureate Norman Borlaug

American, the creator of the famous dwarf wheat varieties in Mexico, visited India in 1957. In a press conference, he said, “If I were a member of the Indian Parliament, I jumped from my seat every fifteen minutes and yell at the top of my voice, fertilizers, farmers more manure.” The fact is that between the fifties and sixties, in independent India, there was a gap between demand and production of food. To answer that, the Indian planners under the influence of American institutions such as the Ford and Rockefeller Foundations and the American Specialty Food Norman Borlaug, the idea of the paradigm shift in agriculture, natural chemical, Brides of local high and high yields of the seeds growing in the designed to absorb popularity as a global brand “miracle seeds”, with the ability to agrochemicals at this point of time. This is a global phenomenon and to the global rise in food contributed site immediately. On the day of world production of foodgrains is estimated at 2100 million tonnes and is based primarily on the use of agrochemicals, chemical fertilizers and pesticides. However, the impact of agricultural chemicals, fertilizers and synthetic pesticides can be observed. There were no data published by an agency of the Indian and the U.S. Environmental Protection Agency (EPA). The EPA in 1991 showed that the estimate of methane emissions from rice paddies Indian equivalent to 37.8 tons per year and accused the Indian rice growers by the global buildup of greenhouse gases such as methane as well as greenhouse gas. Therefore, in India set more weight, go to conventional agriculture and the rice is not always limited to 47% of the total arable area (National Agricultural Policy, 2000). The use of artificial chemical fertilizers, especially nitrogen fertilizer always invite pests which lead to agricultural pesticide applications, in particular synthetic pesticides and two of these significantly impact on the environment.


worldwide use of fertilizer (kg / ha)

Korea – Japan 357 kg – 247 kg

Netherlands – Bangladesh 172 kg – 158 kg

Germany – India 153 kg – 89 kg


weird logic of the recommendation of the use of chemical fertilizers:

plant needs 17 essential nutrients in two groups:

1 Macro-nutrients required by plants in large quantities and

2 Micro-nutrients by plants in small amounts

necessary

Whatever the source, the plants absorb nutrients in inorganic form, only the Macro 3 or large primary nutrients absorbed as in -.

nitrogen (N) as ammonia, nitrates and nitrites

phosphorus (P), calculated as P2O5 (phosphorus)
potash (K) K2O (potash)

three secondary macronutrients include substances such as calcium (Ca), magnesium (Mg) and sulfur (S) which is naturally in the soil and fertilizer to find.


Micronutrients or plant nutrients are expected to actually

minor trace elements like iron (Fe), manganese (Mn), zinc (Zn), copper (Cu), boron (B), molybdenum (Mo) and cobalt (Co) and secondary macronutrients to be in the soil and manure disposal. While there is nothing organic to take in the absorption of nutrients by the plants, but plant is certainly influenced by the original source of this nutrient, it is best if it is from the organic source, the availability is low and release delayed but not to take prolonged and nutrients interact. to avoid in the process chemicals to excessive nitrogen fertilizer applications of phosphorus and potassium make up by plants.

state facts

intensive agriculture, as deemed necessary by the growing food demand of growing population, exhaust natural soil fertility and distort the natural balance of the soil.

It is proposed that said inorganic must be selective, to keep the soil plant nutrition necessary. But their worries are never evaluated or supported.

era of green revolution throughout the world, crops have been largely protected through the use of biocides, pesticides, fungicides etc.and their effects have never been evaluated.

use of synthetic pesticides (kg / ha) United States, Japan, Korea, China and India are 1.5, 10.8, 6.6, 2.25 and 0.38 kg, respectively.

use of synthetic pesticides in recent decades become one of the most important contributions of modern agriculture, but the devastating consequences of course.

PROMOTION Organic Agriculture FACTS

promoters to organic fertilizer for the following reasons.



fertilization is 100-160 years.
not ready to claim that accept the fertilizer, global food production improvement.
Set plants at the edge of the road, mountains and deserts of the survivors of the humus biomass years after years, never be used without fertilizer.
fertilizer will benefit in the brain of the industrial lobby, and is not for farmers and consumers and the environment.
plants contain chemicals with heavy metals and other pollutants, that is not well developed for health.
agrochemicals cause disease and death due to excessive nitrates and pesticide residues.
The kitchen is known as being produced by the use of agrochemicals without essential minerals and vitamins, which in turn inhibit the enzyme systems so important for their own body functions required for food additives and drugs.
fertilizers such as urea and DAP contain heavy metals such as lead and cadmium.

excessive and indiscriminate use of mineral fertilizers has damaged soil health damage leads to a deficiency of macro and micro nutrients.

Why organic foods are better cultivated than inorganic foods: –

Organic foods contain more vitamins, minerals, enzymes, trace elements and even anti-cancer antioxidants than conventionally grown food fight, showed a two-year study in Chicago, USA made. It was also observed that the average level of minerals is much higher than in organic food in conventionally grown foods were. In addition, organic food tastes much better and has always followed a more quality, even without refrigeration.
