Soil & Fertilizers

Importance of Soil test in Soil fertility भूमि की उर्वरता किसी भी राष्ट्र के लिए बहुत महत्व रखती है किसी भी देश की सभ्यता का अंदाजा वहां के भूमि के सदुपयोग या दुरूपयोग से लगाया जा सकता है। हमारी जनसंख्या दिन पर दिन बढती है। जबकि हमारी कृषि योग्य भूमि सिकुडती जा रही है। हमारे पास ऐसा कोर्इ साधन नहीं है। जिससे कि हम भूमि का क्षैतिज विस्तार कर सके अब यह हमारे ऊपर निर्भर करता है। कि हम इनका उपयोग किस प्रकार करे क्योंकि ये हम सभी जानते है। कि सभी वनस्पतियों तथा प्राणियों का जीवन इसी पर टिका हुआ है। आज के युग में जब कृषि भी एक व्यापार...

मृदा मे सूक्ष्म पोषक तत्‍‍‍‍‍‍‍वाें की वर्तमान स्थिति और फसलों पर उनके लक्षण Micro nutrients are essential for the normal growth of plants. Deficiencies of micro-nutrient drastically affect the growth, metabolism and reproductive phase in plants, animal and human beings. Wide spread deficiencies of micronutrients has been found in Indian soils. About 3 billion people in the world are affected with micronutrient malnutrition. Crop plants requires 17 nutrient elements viz. C, H, O, N, P, K, Ca, Mg, S, Fe, Cu, Mn, Zn, B, Mo, Cl and Ni for completing their life cycle. Out of these last eight elements are micro nutrients that are needed in very less amount for crops...

वर्मीकंपोस्ट - उत्पादन और क्रि‍याऐं। Vermicomposting is a method of preparing enriched compost with the use of earthworms. It is one of the easiest methods to recycle agricultural wastes and to produce quality compost. Earthworms consume biomass and excrete it in digested form called worm casts. Worm casts are popularly called as Black gold. The casts are rich in nutrients, growth promoting substances, beneficial soil micro flora and having properties of inhibiting pathogenic microbes. Vermicompost is stable, fine granular organic manure, which enriches soil quality by improving its physiochemical and biological properties. It is highly useful in raising seedlings and for crop production. Vermicompost is becoming popular as a major component...

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...

नाइट्रोजन उर्वरकों के अधिक उपयोग के कारण भूजल प्रदूषण After independence our nation's primary aim was to achieve self-sufficiency in the food production. To achieve this aim we incorporated the primary means of maximizing the yields of agricultural crops through use of fertilizers, pesticides and other chemicals besides improving the inherent quality of the seeds. Though it helped our nation in producing the food for ever-increasing population but the unsustainable path used to maximize the yield caused some grave concerns like that of groundwater pollution. Nearly five decades after the Green Revolution the sustainability of Indian agriculture, and thereby the country's food security, are both facing a serious challenge. Water is vital...

बायोडैनेमिक खेती और इसकी तैयारी के तरीकों Biodynamic Farming is a view of agriculture, based on a holistic and spiritual understanding of nature and humans role in it, which considers a farm as a self-contained evolving organism, relying on home-produced feeds and manures with external inputs kept to a minimum. Preparation The first group of preparation material includes 6 different herbal substances; they are numbered 502-507 and are added in small amounts to manures and composts. So they are collectively called as compost preparations. These numbers are arbitrary, having been chosen by those who first produced the preparations. The second group includes the sprays; they are numbered as 500 and 501. Although not...

How to make quality compost from garbage?  भारतीय कृषि क्षेत्र में पिछले चार दषकों से फसल उत्पादन में जो वृध्दि आई है, इसका मुख्य कारण उन्नत तकनीकों को अपनाया जाना और अधिक मात्रा में रासायनिक उर्वरकों और कीटनाषकों का प्रयोग है। अपनी जरूरतों को पूरा करने के लिए इन कृत्रिम पदार्थों का भारी मात्रा में प्रयोग किया जा रहा है। मिट्टी की स्थिति की अनदेखी की जा रही है। इसके कई दुष्परिणाम हमारे समक्ष धीरे-धीरे प्रकट हो रहे हैं। मिट्टी के प्राकृतिक गुण्ा धीरे-धीरे समाप्त होते जा रहे हैं। इसके अलावा प्राकृतिक गुण के अभाव में उत्पादन लागत में वृध्दि हो रही है। मिट्टी में जीवांष या कार्बनिक पदार्थों की कमी...
