Reply by the Central Pollution Control Board (CPCB) in compliance to the National Green Tribunal (NGT) order dated January 21, 2024 in the matter of ‘News item titled “Feeling anxious? Toxic air could be to blame” appearing in Times of India dated 10.10.2023’. NGT had directed CPCB to file a …
A study examined the dynamics of soil physical and chemical properties under different land use systems in parts of Chambal region of Rajasthan. Soils were sampled at surface (0-15cm) layer under (i) irrigated sorghum/soybean-wheat rotation for over 20 years, (ii) ten-years-old Leucaena leucocephala plantation, (iii) grasslands for >15 years with …
The agriculture department has invited expressions of interest (EOIs) from recognized NGOs, cooperative societies, self help groups and farmers clubs to carry out a soil survey in the state. The project called 'the soil nutrient status of Goa: Major and micronutrients', has been taken up under the central government's Rashtriya …
The evolution of land–atmosphere–ocean models has resulted in the need for hydrologic models applicable to large areas and river basins. Such developments offer new challenges and opportunities for hydrologists to understand the hydrologic response of areas as large as continents. In the present study, the ability of variable infiltration capacity …
State government is trying to decrease area under paddy In order to give a fillip to maize research and cultivation in the state, the Punjab government has approved transfer of 100 hectares in Ladowal near Ludhiana free to the Indian Council of Agriculture Research (ICAR) for setting up a Directorate …
Approximately 1700 Pg of soil carbon (C) are stored in the northern circumpolar permafrost zone, more than twice as much C than in the atmosphere. The overall amount, rate, and form of C released to the atmosphere in a warmer world will influence the strength of the permafrost C feedback …
The potential for regional climate change arising from adoption of policies to increase production of biofuel feedstock is explored using a regional climate model. Two simulations are performed using the same atmospheric forcing data for the period 1979–2004, one with present-day land use and monthly phenology and the other with …
An understanding of the dynamics of soil organic carbon (SOC) as affected by farming practices is imperative for maintaining soil productivity and mitigating global warming. The objectives of this study were to investigate the effects of long-term fertilization on SOC and SOC fractions for the whole soil profile (0–100 cm) …
A field experiment was conducted to (i) examine the diurnal and seasonal soil carbon dioxide (CO2) fluxes pattern in rice paddy fields in central China and (ii) assess the role of floodwater in controlling the emissions of CO2 from soil and floodwater in intermittently draining rice paddy soil. The soil …
Improved understanding of changes in soil recalcitrant organic carbon (C) in response to global warming is critical for predicting changes in soil organic C (SOC) storage. Here, we took advantage of a long-term field experiment with increased temperature and precipitation to investigate the effects of warming, increased precipitation and their …
Nitrous oxide (N2O) is a greenhouse gas that is also capable of destroying the ozone layer. Agricultural soil is the largest source of N2O. Soybean is a globally important leguminous crop, and hosts symbiotic nitrogen-fixing soil bacteria (rhizobia) that can also produce N2O. In agricultural soil, N2O is emitted from …
Flooded rice fields are an important source of the greenhouse gas CH4. Possible carbon sources for CH4 and CO2 production in rice fields are soil organic matter (SOM), root organic carbon (ROC) and rice straw (RS), but partitioning of the flux between the different carbon sources is difficult. We conducted …
Traditional agro-systems in arid areas are a bulwark for preserving soil stability and fertility, in the sight of “reverse desertification”. Nevertheless, the impact of desert farming practices on the diversity and abundance of the plant associated microbiome is poorly characterized, including its functional role in supporting plant development under drought …
Phytolith occluded carbon (PhytOC) which is stable in the soil environment is considered to be an important fraction of soil organic carbon and substantially contributes to the terrestrial carbon sequestration for long periods (millennia). Phytoliths are silica bodies produced by plants as a result of biomineralization process. During this process, …
The present study on the plant nematodes associated with Bt cotton crop growth in northern Karnataka, India covered several aspects like a nematode random survey in Bt cotton-growing areas of the state, nematode community analysis, pathogenicity and biology of a dominant nematode and reaction of Bt cotton cultivars and hybrids …
Microzonation, on a scale of 1:10,000, is being carried out to formulate building codes specific to areas in the city. High damage risk zone — technically termed as Zone IV— is what Delhi has been defined as. In simple words, this means Delhi has the structural make to be the …
Grasslands are structured by climate and soils and are increasingly affected by anthropogenic changes, including rising atmospheric CO2 concentrations. CO2 enrichment can alter grassland ecosystem function both directly and through indirect, soil-specific effects on moisture, nitrogen availability and plant species composition, potentially leading to threshold change in ecosystem properties. Here …
Arid and semi-arid ecosystems cover ~40% of Earth’s terrestrial surface, but we know little about how climate change will affect these widespread landscapes. Like many drylands, the Colorado Plateau in southwestern United States is predicted to experience elevated temperatures and alterations to the timing and amount of annual precipitation. We …
A numerical model of salt marsh evolution shows that competition between mineral sediment deposition and organic matter accumulation determines the net impact of climate change on carbon accumulation in intertidal wetlands.
Temperate climatic condition of Kashmir is well suited for bivoltine sericulture. The sericulture in Kashmir valley sustains on tree type of mulberry. These plants are available on roadside, river bund and the borders of agricultural fields as they can grow under diverse climatic conditions. The present trend is towards establishing …
