Initially usage of chemical fertlizers boosted agricultural productivity but at the same time it decimated the soil humus and soil organic carbon. Over the time, gradually the productivity has gone down due to humus depletion. Chemical fertilizers application affected the quality of farm product adversely. Decreasing qualitative yield is the serious concern for National Food and Nutrition Security.
The most important element to ensure the fertility of the soil is Humus. Salty residues from artificially synthesised chemical fertilizers is being deposited in soil. The residues are affecting the soil fertility, soil's water absorption capacity, soil's moisture retention capacity and the beneficial microbes in soil. Salty residues from artificially synthesised chemical fertilizers are the main reasons of soil compaction, poor aeration, less soil porosity, crop's inability to absorb the naturally available plant nutrition from soil.National health has been adversely affected due to inferior nutritional quality of farm produce. Farm produce are deficient in nutritional value, micronutrients and vitamins. In addition to chemical fertilizers and toxic cropcare products, GM Seeds have added to the plight. Bees and butterflies are on the brink of extinction.
Initially we failed to asses the damage which chemical fertilizers and toxic crop protection products can cause to our farms/food. We forgot the fact that we are going to eat the same produce which we are producing using toxic chemical inputs . We relied on chemical fertizers & toxic cropcare products and compromised with quality to increase quantity. Sooner than later we will be in difficult situation when we may lose our Vedic Seeds (deshi seeds) completely. Multinational companies have start selling sterile seeds at exorbitant prices and we will have no option other than to buy these sterile seeds at exorbitant prices once we lose our regenerative and reproductive Indian Deshi Vedic Seeds. We must keep the fact in mind that Govt will not be able to control the situation, food security and prises of seeds, as we will not be having reproductive indian vedic seeds. We will be compelled to buy the sterile seeds at exorbitant prices every season.

THE PRESENT CRISIS OF INDIAN AGRICULTURAL SUSTAINABILITY

The continuous use of chemical fertilizers has decimated the 'Soil Humus'. The fertile holy top soil has lost its water retention capacity due to decrease in Soil Humus and Soil Organic Carbon (SOC) content. Now plant nutrition and soil & water pollution due to leaching of fertilizers specially nitrogenous fertilizers has become a serious concern. India's fertile holy top soil in on the verge of becoming barren due to continuous usage of chemical fertilizers and decreasingsoil organic carbon. Quality and quantity of agricultural production is gradually declining.
The ill effects of inferier quality farm produce are visible now. The nutritional value of farm produce has gone down.
CONTINUOUS APPLICATION OF CHEMICAL FERTILIZERS HAS DECIMATED THE HUMUS LEVEL IN SOIL, ADVERSELY AFFECTED THE UNDERGROUND WATER RECHARGING PROCESS AND DEPLETED THE UNDERGROUND WATER LEVEL.
