Soil Health- an integral part of the beneficial and sustainable agriculture. भारत की लगभग दो तिहाई आबादी की जीविका का मूल आधार कृषि है। शहरीकरण और औद्योगीकरण के कारण कृषि योग्य जमीन दिन प्रतिदिन घटती जा रही है, साथ ही साथ इसकी गुणवत्ता में उल्लेखनीय कमी आती जा रही है। बीसवी श्‍ादी के उत्तरार्ध में देश मेे हरि‍त क्रांति से कृषि उपज में गुणात्मक बढ़ोत्तरी हुई। जिसके मूल में अधिक उपज देने वाली किस्में, रासायनिक उर्वरक एवं व्यापक पैमाने पर पाक-संरक्षक उपायों का अपनाये जाना था। जिसके दुष्परिणाम कृषि उत्पादन की कमी के रूप में बाद के दशकों में दिखाई देने लगे। जिसका एक प्रमुख कारण मृदा गुणवत्ता में आई उत्तरोतर कमी को...

बायोचर - कृषि का भविष्य The amount of carbon in the soil is a direct indication of good quality of soil. Higher carbon stocks have a direct correlation with increased agricultural yields through improved soil health. In the current scenario of climate change and global warming, much of carbon in atmosphere has to be sequestrated into soil carbon pool so that increasing CO2 in the atmosphere and resulting warming could be reduced. The use of biochar can be a simple yet powerful tool to combat climate change by sequestering much of atmospheric carbon into soil as well as providing an opportunity for the processing of agricultural and other waste into useful clean energy. What is...

समस्याग्रस्त मिट्टी का प्रबंधन कैसे करें For the management of problematic soils,  some general principles has to be considered for proper implementation of the reclamation measures. The total soluble salt concentrations in the root zone have to be decreased to control osmotic effects on plant growth. Maintenance of total soil moisture tension must be ensured at optimum level so that plant roots can absorb an adequate amount of water. Water flows through the soil in the direction of maximum decrease of hydraulic head and the flow velocity is proportional to the hydraulic gradient. The design and layout of drainage system are controlled by this principle. The availability of good quality water is of paramount for...

सेलाइन (खारा) मिट्टी के सुधार की तकनीक Accumulation of excess salts in the root zone resulting in a partial or complete loss of soil productivity is a worldwide problem. Soil salinity has caused heavy loss of national wealth in India. Out of 329 million hectares of land in the country, about 175 million ha (53 %) is suffering from degradation. The extent of this problem area as given by different sources varies from 8.56 M ha to 10.9 M ha. According to Central Soil Salinity Research Institute (CSSRI), Karnal, 1.7 M ha of land is affected by salinity among the 6.7 M ha of salt affected land. World as a whole is...

कृषि‍ फसलों में फास्फोरस उपयोग दक्षता बढ़ाने के लिए रणनीतियां Phosphorus (P), an essential macronutrient for all living organisms, is a vital component for building blocks of genes and chromosomes. In plants, it plays a role in virtually all biochemical processes that involve energy transfer.  It is a constituent of adenosine triphosphate (ATP), which is often termed as ‘energy currency’ of the plant cell. In plant, P is essential for photosynthesis, respiration and root growth, flowering, fruiting, seed setting and seed yield. The total P content in agricultural crops ranges from 0.1 to 0.5%. Phosphorus is taken up by the plant as primary orthophosphate ion ( H2PO4- ) but it is also...

मृदा स्वास्थ्य को नि‍रंतर बनाए रखने के लिए मिट्टी कंडीशनर महत्वपूर्ण कारक  Soil conditioners as a source of plant nutrients has been found beneficial in improving Physical, Chemical and Biological conditions of soil, thereby increased productivity of crops. If the soil had very low pH, P and extractable Si then it is necessary to use soil conditioners for improving soil pH and some elements such as P and Si. Farmers can adopt this technology to improve the crop production.  A soil conditioner is a product which is added to soil to improve the soil’s physical qualities, especially its ability to provide nutrition for plants. In general usage the term soil conditioner is often...

भारत की मृदा व फसलों में बोरोन तथा मोलिब्डेनम की कमी और उर्वरकों के प्रयोग सेे उनमे सुुुुधार   Plants require eight micronutrients for their growth and development. Out of them, Boron (B) and Molybdenum (Mo) are anionic micronutrients found to be deficient in Indian soils and crops. The essentiality of the B and Mo for higher plants was first established by K. Warington in 1923 and by D. I. Arnon and P. R. Stout in 1939 respectively. The information regarding deficiency of B and Mo in soils in India, their role in plant growth and deficiency symptoms and fertilizers containing B and Mo for amelioration is being provided for the benefit...
