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 ...

अनुकूलित उर्वरक: उर्वरको की सर्वोत्तम प्रबंधन क्रि‍याऐं Fertilizer is one of the key inputs in augmenting food grain production. Considering the fact that about 40-50% of the applied fertilizer nitrogen is lost by ammonia volatilization, leaching, run-off and de-nitrification, development of more efficient nitrogen fertilizers such as neem-coated urea needs to be encouraged by providing price incentive to the fertilizer manufacturers. Most of the present suite of fertilizer products were developed more than 40 years ago. Over the past 25 years, no “new” efficient fertilizer product has been developed particularly no product affordable for use on food crops by farmers in less developed countries. New and improved fertilizers are critical to help feed the...

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...
