TAILIEUCHUNG - Effect of conservation agriculture on soil physical health

Anthropogenic activities have been the main cause of perceived global warming later in the middle of 20th century. Tillage intensive and highly mechanized traditional agriculture production system has been identified responsible for soil erosion hazards, surface and groundwater pollution, and more water consumption. As a result, the agricultural production system is becoming unsustainable. To achieve the food security of an ever growing population and alleviate poverty besides maintaining agricultural sustainability in the existing situation of degrading natural resources, undesirable effects of climatic inconsistency, rising price of inputs and unstable market prices of food, most of the Asian countries have to face these major challenges. | EXCELLENT PUBLISHERS International Journal of Current Microbiology and Applied Sciences ISSN 2319-7706 Volume 7 Number 02 2018 Journal homepage http Review Article https Effect of Conservation Agriculture on Soil Physical Health Vikas Rai1 Pragati Pramanik1 Pramila Aggarwal1 Prameela Krishnan1 and Ranjan Bhattacharyya2 1Division of Agricultural Physics ICAR-Indian Agricultural Research Institute New Delhi India 2Center for Environment Science and Climate Resilient Agriculture ICAR-Indian Agricultural Research Institute New Delhi India Corresponding author Keywords Conservation agriculture Zero tillage Hydrothermal regimes Climate change Conventional tillage Article Info Accepted 04 January 2018 Available Online 10 February 2018 ABSTRACT Anthropogenic activities have been the main cause of perceived global warming later in the middle of 20th century. Tillage intensive and highly mechanized traditional agriculture production system has been identified responsible for soil erosion hazards surface and groundwater pollution and more water consumption. As a result the agricultural production system is becoming unsustainable. To achieve the food security of an ever growing population and alleviate poverty besides maintaining agricultural sustainability in the existing situation of degrading natural resources undesirable effects of climatic inconsistency rising price of inputs and unstable market prices of food most of the Asian countries have to face these major challenges. As a result a drastic change in agricultural practices is required for achieving desirable productivity while nourishing the natural resources. In this situation to address the sustainability of agriculture globally the concept of Conservation agriculture CA evolved. CA system is very effective natural physical protection against weather rainfall wind dry or wet periods and improving soil physical health like reducing bulk density BD and penetration .
