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 …
This study was conducted to test the hypothesis that spatial variations in soil microbial variables in a Thai rice paddy are accurately described by multivariate profiles of the soil bacterial communities. The authors found that community-level physiological profiles of soil bacterial communities could better describe the population density of Rhizoctonia …
Biomass estimation and productivity studies were conducted in 3, 6 and 9 years old plantations of Dalbergia sissoo in sodic lands of Sultanpur District in Eastern Uttar Pradesh, India. A set of regression equations for biomass production per unit area was also developed to be applied on regional basis.
The Nagaon Paper Mill, a public sector pulp and paper mill, a unit of Hindustan Paper Corporation Limited, is located at Jagiroad, Morigaon district, Assam and generates about 448 tonnes of lime sludge per day as solid waste. Instead of marketed lime, lime sludge waste of the paper mill can …
Cyclone Aila has altered their calculations. Hit by crop failure due to increased salinity caused by sea water surge, the farmers of the Sunderbans were pinning hope on the low-yield but salt-resistant paddy varieties that their forefathers cultivated. Only to realise that the high-yield varieties that they had preferred to …
BHUBANESWAR: Sustainability of crop production depends greatly on soil fertility management. Though organic manures and bio-fertilisers can be supplements it to some extent, scientists feel that there is a greater challenge ahead to meet the projected food grain production by 2025. On the other hand, ever increasing use of fertilisers …
Kolkata: Faced with secondary nutrient deficiency in soil, threatening to drag productivity lower in several districts, West Bengal is preparing a soil map for the state. The state government will concentrate on site specific nutrient management after the soil map is ready. The map, being prepared by department officials, will …
In arid environments such as deserts, nitrogen is often themost limiting nutrient for biological activity. The majorityof the ecosystem nitrogen flux is typically thought to be drivenby production and loss of reactive nitrogen species by microorganismsin the soil. We found that high soil-surface temperatures (greaterthan 50
JAIPUR: The fire raging at the Indian Oil Corporation depot at the Sitapura Industrial Area near here since last Thursday has led to an environmental crisis in the capital city. The thick black plumes of smoke have spread to dozens of villages and residential colonies, hampering visibility and creating panic. …
The knowledge of hydrological variables (e.g. soil moisture, evapotranspiration) are of pronounced importance in various applications including flood control, agricultural production and effective water resources management. These applications require the accurate prediction of hydrological variables spatially and temporally in watershed/basin. Though hydrological models can simulate these variables at desired resolution …
S. Sundar MADURAI: Amid demands to declare Madurai a drought-hit district, here is a tract of around 1,500 acres of land that has little trace of drought-like situation in the district. Greenery here touches the horizon. A variety of cultivated crops makes this land an oasis in the district where …
Soil exhaustion is a major concern particularly in ferruginous soils of the tropics and restoration of soil quality through management of soil organic carbon (SOC) is one of the options to combat the situation. To understand the scope of different systems to sequester organic carbon in ferruginous soils (Typic Rhodustalfs), …
Phosphate-based fertilizers have helped spur agricultural gains in the past century, but the world may soon run out of them. Natasha Gilbert investigates the potential phosphate crisis.
Traditionally agriculturalists of western Madhya Pradesh had adopted practices that made most use of the soil moisture and conserved the ecosystem to ensure a sustainable output. However, from the decade of the 1970s a more intensive agricultural system was introduced involving the use of hybrid seeds, chemical fertilisers and higher …
This study shows the importance of physical, water retention and transmission properties of soils in relation to water management/hydrological studies of paddy fields in the vicinity of Nirjuli (Arunachal Pradesh). Soil samples were collected at varioud depths at Nirjuli village, Modern village, Doimukh and Banderdewa.
The way that industrial agriculture has treated soils has been a key factor in provoking the current climate crisis. But soils can also be a part of the solution, to a much greater extent than is commonly acknowledged. According to our calculations, if we could manage to put back into …
Rain water conservation techniques, like large compartmental bunding and furrow opening in between the crop rows in combination with organic sources were evaluated for their impact on increasing the productivity of cotton+soybean intercropping system.
Computer based programming models are useful analysis tools to understand the watershed planning cum management problem and to find solutions through the best management practices (BMPs) and bio-engineering measures.
Efficient management of nutrients constitutes one of the most important factors to achieve agronomic and environmental targets of intensive crop production systems. Agricultural intensification requires increased uptake of nutrients by crops. The depletion of nutrient reserves from the soil is often a hidden form of land degradation.
