Use of Biodegradable Nanoclay Polymer Composite (NCPC) for controlled release of nitrogen fertilizer in soil पौधों के विकास के लिए सबसे महत्वपूर्ण तत्व नाइट्रोजन है जिसकी आवयश्कता बड़ी मात्रा में होती है अतः  कमी से बचने के लिए इसे उर्वरक के द्वारा मिट्टी में डालना अति आवश्यक है। वर्त्तमान समय में, किसानों द्वारा अंधाधुन उर्वरकों का  प्रयोग उत्पादन सीमा में वृद्धि के लिए किया जा रहा है। दक्षिण पूर्व एशिया में यूरिया सबसे अधिक उपयोग की जाने वाली उर्वरकों की श्रेणी में है इसका एक कारण इसमें मौजूद उच्च नाइट्रोजन की मात्रा और दूसरा इसके उत्पादन में अपेक्षाकृत कम लागत का होना है। हालांकि, पारम्परिक  उर्वरकों से नाइट्रोजन  का लगभग 40-70% पर्यावरण में ...

सटीक नाइट्रोजन उर्वरक प्रबंधन के लिए आधुनिक उपकरण और तकनीक Food production is commensurate with fertilizer usage. Among the three major fertilizers, nitrogen, phosphate and potassium, application of nitrogenous fertilizers is the maximum. It is reported that China, India and Pakistan together consume approximately 70% of nitrogen fertilizer consumed globally. These figures of nitrogen fertilizer consumption point towards emerging environmental pollution issues. The estimated food production demands would require application of N fertilizer to the tune of 116.0 million tonnes in 2016 and 58% of it would be required in Asia alone of which India’s share would be 30% (FAO Report, 2012). The consumption of N fertilizer in form of urea has increased many...

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...
