Abstract Hydrothermal sensitivity of soil organic carbon decomposition in relation to global climatic changes is great importance for C cycle an agro‐ecosystem. To assess the sensitivities SOC as affected by different sources and mineral fertilizer Inceptisol, samples from a 5‐year‐old field experiment were collected unfertilized control, 100% NPK, vermicompost, compost, farmyard manure (FM) treated plots analyzed total C, labile fractions mineralization kinetics incubating soils at 25 35°C...
Soil nitrogen (N), phosphorus (P) and potassium (K) are important macronutrients for crop production productivity. Assessment of spatial distribution stock N, P K in soil the need hour judicious nutrient management through precision agriculture. An attempt was made to prepare map available using geostatistical techniques. In total 150 georeferenced surface samples (0–25 cm depth) were collected at 1 km × grid interval three major land use systems viz., crop, plantation agroforestry (like...
The aim of this investigation was to prepare and evaluate organic manures (vermicompost, compost FYM) mineral fertilizers on crop productivity changes in soil carbon (SOC) fertility under a four-year-old maize-wheat cropping system. results demonstrated that yields nutrient uptake by crops increased significantly plots receiving either alone or combination than unfertilized control. Application also enhanced SOC, N, Olsen-P ammonium acetate-extractable K (NH4OAc-K) after both the crops....
Mulberry (Morus indica L.) is a foliage crop cultivated extensively in the North-Eastern India under rainfed condition for rearing silkworm (Bombyx mori L.). An attempt was made through field experimentation to develop soil-cum-nutrient management package mulberry cultivation acid soil condition. Effects of different treatment combinations comprising NPK, farmyard manure (FYM), lime and boron (B) on important properties, yield quality L. var. S1635) leaf were assessed identify best package....
The Meghalaya plateau occupying a major portion of entire state remains as an important part the ancient Deccan plateau. A detailed soil survey (1:10,000 scale) Jirang block Ri-Bhoi district was carried out using IRS-P6 LISS IV and Cartosat-1 images. Typical pedons representing landforms study area viz., denudational hills, inter hill valley plain developed from granite–gneiss occurring under varying land use were characterized, classified assessed. soils deep to very deep, dark grayish...
Availability of safe drinking water is a major concern in many parts the world. While filtration units operating on various principles are available to combat this, most require electricity, which may not be consistently such areas. In present study, we have designed and demonstrated disinfection system that can operate purely gravity, without any electricity. For potassium hydroxide modified copper-impregnated activated carbon (KOH-Cu-AC) hybrid was used as filter medium for disinfection,...
Accurate fluoride measurement in water is required for selecting safe sources or treatment options to lessen its impact on public health. A low-cost, portable device has been developed as a rapid system. It works with an optimal concentration of alizarin red S-zirconium complex (ARS-Zr, the sensor reagent). The LED-phototransistor-based assembly detect changes light absorbance at 527 nm, due monotonically decreasing ARS-Zr increasing water. We have optimised reagent composition device,...
Assessment of organic carbon fractions in soil provides the basis to ascertain vulnerability an ecosystem climate change. In present study, we assessed SOC four pedons under contrasting landforms i.e., denudational low hill, upper plateau, lower plateau and valley Meghalaya India. Results indicated that soils studied were acidic nature, cation exchange capacity base saturation. Further, surface (0-30 cm) high Walkley Black C (WBC) content (0.83-1.13%) located different landforms. The density...
