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...

मिट्टी में उर्वरकों का प्रबंधन The fertilizers are becoming costly input day by day. Hence it is felt necessary to study the efficient use of this input. So some important points are given here to increase fertilizer use efficiency and to get higher yield. 1. Management of Nitrogen fertilizers in soil Nitrogen is lost from fertilizers by ways as follows: Volatilization Ammonia volatilization is an economic loss to the farmer in terms of both drained fertilizer prices and decreased crop yields. Some important facts are as follows: The ammonia volatilizing capacities of the fertilizers are graded as urea > ammonium sulphate > ammonium chloride > ammonium nitrate. The ammonia volatilizing capacities of the soils are graded as...
