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 …
there has been a long-standing debate on whether organic agriculture can ensure global food security. Even some advocates of organic are not sure about this. A recent study claims organic farming can produce as much food as chemicals-based farming does. The study says organic methods of food production can contribute …
A research team at the University of Minnesota in USA found antibiotics in plants. The root of the problem was in the soil: manure from animals that were administered antibiotics. The plants tested included tomato, lettuce and potato. Given this, says the research team led by Satish Gupta, a shift …
lakkhan Raghuwanshi had a bad harvest last monsoon. The farmer from Shyampur village, Guna district, cultivated soyabean, wheat and chana in 121 hectare (ha), of which he sowed soyabean in 61 ha. Despite the high-quality seeds sowed, the yield was a meagre 15 quintals per ha. "I got my land …
Rainfed agriculture productivity has constrained even in watershed areas after the termination of the watershed development activities in most places in India due to lack of exit mechanism and social regulation on use of groundwater. Under high risk, low productivity and fragile rainfed farming situation, 'water bodies' are found to …
Deoiled cakes are the residues left after the oil is extracted from the oil containing seeds. They are one of the important organic source for plant nutrients. The deoiled cakes to large extent are used as concentrated organic manures. They contain nitrogen, phosphorus, potassium along with a large percentage of …
Soil is a major component of any aquatic environment, which not only holds water for aquatic animals but also enriches the water body with various nutrients required for biological production.
A field experiment under runoff plots was conducted at Devala, Gudallur taluk of the Nilgiris from 2001 to 2003 to evaluate the impact of vegetative barriers and mechanical measures on erosion losses on 25 per cent sloping land under cultivation of cassava.
In India, chemical degradation of lands is taking place at an annual rate of 0.15-Mha. This is about 10 per cent of the annual global rate of about 1.5-Mha. Due to this, about 3.22 per cent of land area in the country has already become salt affected. Literature search reveals …
a new study in a high carbon content paddy field of West Bengal has questioned India's projected methane emission levels, suggesting that if rigorous research is carried out in the eastern and north-eastern parts of the country on high carbon agricultural land, our methane emission figures might actually go up …
The hot arid regions of India in economically and environmentally disadvantaged part of the country with unique problems. These, ecosystems are highly fragile and large liabilities causing severe impediments in development programmes. Despite of hostile conditions, Indian hot arid zone are fairly well vegetated and tree species diversity perhaps much …
In India 18,289 hectares of land is under various type of land degradation due to coal mining in which 1100 ha is by overburden dump. With the increase demand of coal and its opencast mining degrade 1400 ha of fertile land every year. This deterioration in the fertility is due …
A study was conducted to work out the effects of leguminous crops with mulberry in Doon Valley under irrigated conditions. The work was conducted for three consecutive years (2001-2003) in S-146 variety of mulberry plantation. Dec 2006
Studies conducted on Ardu (Ailanthus excelsa) based agrisilvi system of agroforestry during 1999-00 to 2001-02 have indicated beneficial effect of Ardu on environment and soil health. Dec 2006
Soil profiles of Kathmandu urban area exhibit significant variations in magnetic susceptibility and saturation isothermal remanence (SIRM), which can be used to discriminate environmental pollution. eprints.lib.hokudai.ac.jp/dspace/handle/2115/38429
Farmers's wisdom of soil taxonomy and fertility management dynamics is based on trial and error, problem solving and group approach to manage the natural resources. The farmers' knowledge of defining the soil taxonomy and fertility management practices is compatible to their adaptive skills and rich source of location-specific ecological information. …
Measurement of unsaturated hydraulic conductivity in vadose zone is a very difficult task. It is estimated using mathematical or empirical relations. The unsaturated hydraulilc conductivity with respect to water content or suction is estimated using standard empirical relations. These empirical relations use saturated hydraulic conductivity (Ks) as one of the …
the use of combine harvesters in India for rice and wheat is generating millions of tonnes of crop residue every year. To dispose the waste, farmers usually burn it. This causes significant loss of nutrients in the soil and destroys its microbes, besides adding to greenhouse emissions, a study by …
The rice-wheat annual double cropping system occupies an estimated 0.5 million hectares in Nepal where it provides food for about 23 million people. Current production levels of both rice and wheat are far below their reported potential with N-deficiency being the major production constraint. Pot and field experiments were conducted …
The paper describes the effect of rains on vegetal cover, different traditional practices and soil properties in the dry and monsoon period. Seven landuse systems i.e. open pine forests, tea plantation, rainfed agriculture, degraded land, grassland, recently restored site and a bare land were identified in the Bhetagad watershed of …
china’s agricultural revolution has come at a cost. With farmers abandoning the millennia-old tradition of growing rice in favour of fruits and vegetables, the soil quality has declined owing to the application of too much fertiliser. This is causing a profound and detrimental affect on the agricultural produce. These are …
