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...

नाइट्रोजन उर्वरकों के सुरक्षित और लाभदायक उपयोग के लिए सर्वश्रेष्ठ प्रबंधन पद्धतियां Indian agriculture has witnessed a tremendous fourfold increase in food production over the past three decades. This enhanced food grain production later known as ‘green revolution’ could be mainly attributed to the introduction of high-yielding, input responsive cultivars of wheat and rice in the mid-1960s and to the increased availability and use of chemical fertilisers, especially the nitrogenous (N) fertilizers. Nitrogenous fertilizers supply N which is very essential for plant growth and development and mainly supplied to the crop plants in the form of urea, Diammonium phosphate (DAP) etc. When N fertilizers are used correctly they are very beneficial, but...

Fertilizers use efficiency to increase profit उर्वरको का सही समय व सही तरीके से उपयोग निष्चित ही इसकी उपयोग क्षमता बढ़ाता हैं। परिस्थिति अनुसार व फसल अनुसार उर्वरक देने से उपज मे भारी वृध्दि होती हैं। फसल की आवष्यकता के तत्वों को फसल में देने का अलग - अलग समय निम्नानुसार हैं। नत्रजन :- पौधो को नत्रजन की आवष्यकता वृध्दि के आरम्भ मे कम वृध्दि के समय अधिक व वृध्दिकाल व परिपक्कता के समय के बीच कम होती। अत: नत्रजन के उर्वरक की कुछ मात्रा बुआई के समय व शेष मात्रा वृध्दिकाल तक देते हैं।जो फसलें 4-5 महीने में पकती हैं उनको नत्रजन की कुल मात्रा दो बार में, जो 9 - 12 महीने...

वर्मीकम्पोस्ट - खाद या उर्वरकों की रानी  Vermicompost is an organic manure (bio-fertilizer) produced as the vermicast by earth worm feeding on biological waste material; plant residues. Vermi casts are popularly called as 'Black gold'. This compost is an odorless, clean, organic material containing adequate quantities of N, P, K and several micronutrients essential for plant growth. Vermicompost is a preferred nutrient source for organic farming, which enriches soil quality by improving its physicochemical and biological properties. It is eco-friendly, non-toxic, consumes low energy input for composting and is a recycled biological product. Vermicompost is becoming popular as a major component of organic farming system. Base materials required for Vermi composting: Crop residues ,tree leaves and...
