As more and more multibillion-dollar projects for sequestering carbon dioxide (CO2) deep within the Earth seek financial support, human-formed fertile black soils in the Amazon basin suggest a cheaper, lower-tech route toward the same destination. Scattered patches of dark, charcoal-rich soils known as terra preta (Portuguese for "black earth") are …
Tropical forests can capture carbon FORESTS hold the centrestage in climate change. They can reduce carbon emissions up to 10-20 per cent of what has been projected by 2050. The Intergovernmental Panel on Climate Change has said that the greatest potential for carbon capture exists within tropical forests. Based on …
Although soils are generally considered to wet readily, some are actually water-repellent at the surface. This communication presents the recent progress in relating the severity of water repellency to different soil management practices and land uses under the lower Himalayan region of India.
C. Jaisankar RAMANATHAPURAM: It is a dream come true for 33 members of various families of Vedhakaran Valasai near Thiruppullani in the district, as they are about to reap profits by cultivating groundnut and vegetables in their 10.5-acre land, which was barren for the past 30 years, thanks to community …
The present work reports on the habitat characteristics of some weeds of pulses crop field. Reported weeds are more adapted in the Gangetic alluvium soil under certain climatic factors.
In the present study, red lateritic soil and farmyard manure were used in seven compositions for raising seedlings of Albizia amara. The emergence of seedlings increased with increasing the ratio of farmyard manure (67.7 to 89.3%) while pure farmyard manure lodged 71.4%.
A field experiment was conducted at Agronomy farm, S. K. N. College of Agriculture, Jobner to study the effect of compaction on bulk density, hydraulic conductivity and moisture content of soil during kharif seasons of the year 2002 and 2003. The experiment was consisting of three levels of compaction 0, …
Soil moisture is an important component of the hydrological cycle. It contributes significantly to the water and energy flux from the surface of the earth, which in turn drives the atmospheric circulation. In spite of its importance, information on soil moisture is difficult to get. In India, soil moisture-measuring stations …
In drought conditions, forest soils can serve as a small but surprisingly persistent sink for the greenhouse gas nitrous oxide. The effect highlights a research avenue necessary for predicting Earth
POLAND: An ancient technique of plowing charred plants into the ground to improve the quality of soil may also trap greenhouse gases for thousands of years and forestall global warming, which is being caused by the emission of harmful green house gases, a team of scientists and experts working on …
Performance of five year old coppice plants of Dalbergia sissoo was evaluated for biomass production on a sub-standard soil site. The study reveals potential of short rotation coppice system in D. sissoo for obtaining biomass energy and minor timber on sub-standard soil sites.
Regeneration status of a forest indicates its health and a healthy forest ensures good future generations. Sal species which regulates its environment and forms pure stands in Doon Valley. Despite having a wide niche, the species has a great regeneration problem due to various anthropogenic disturbances, limitations of soil moisture, …
This submission highlights ways in which the potential of agricultural mitigation in general, and from smallholder agriculture in particular, may be realized under a future global climate change agreement. It addresses quantifying mitigation and dealing with uncertainty issues associated with soil carbon sequestration, enabling institutional and policy environments required to …
Soil fauna is perhaps the least known frontier of biological diversity. The present study was carried out to observe the changes in the soil faunal diversity subsequent to slash and burn agriculture or shifting cultivation locally called 'Jhumming; or 'Jhum'. These attributes were observed in relation to the density, vertical …
A field experiment was conducted in Allahabad District of Uttar Pradesh to test the possibility of utilizing fly ash, in afforestation of sodic soil with Albizia procera, as a substitute of fertilizers and amendments. Fly ash proved to be a good substitute of rice husk, was superior. Similarly the treatments …
Sikkim is facing great challenge to protect the natural resource from land degradation and erosion. The whole state of Sikkim is hilly and cris-crossed by number of streams. Soil erosion is one of the major problems. The hills of Sikkim mainly consist of gneissose and half-schistose rocks, making their soil …
In a new research, scientists at the University of Toronto Scarborough (UTSC), Canada, have shown that global warming can actually change the molecular structure of organic matter in soil. "Soil contains more than twice the amount of carbon than does the atmosphere, yet, until now, scientists haven
It does kill the nasty bollworm. What about friendly microbes? transgenic crops come with a range of biosafety concerns, which are contested because the discussion of such crops is highly polarized. Researchers of the Indian Agriculture Research Institute (iari), in a recent study, said Bt-cotton may affect soil microbes and …
