Is biomass production profitable?
Cellulosic ethanol has emerged as a leading candidate biofuel that could contribute significantly to meeting U.S. liquid fuel demand while reducing net greenhouse gas emissions. Feasibility of large-scale cellulosic ethanol production depends not only on the development of cost effective processing methods, but also on the availability of large quantities of cellulosic biomass for conversion to ...

Nitrogen mysteries in urban grasslands
Areas of turf-forming species created and maintained by humans for aesthetic and recreational (not grazing) purposes, i.e. “urban grasslands” are an extremely common, but poorly studied ecosystem type. There are over 150,000 km2of urban grasslands in the U.S. and many receive high rates of fertilizer, creating concerns about nutrient runoff to streams, lakes, and estuaries and emissions of ...

Using rotation crops to improve soil quality
Soil quality issues are being researched within two crop rotation experiments that started in 1994 at Narrabri. They compare several crop rotations that include or exclude legume phases. The data presented here relate to the most recent 2-year cycles of these experiments. Following cotton harvest at the end of the previous cycle, rotation crops are sown (winter cereal, faba beans (grain) or vetch ...

Mysteries of soil and nitrogen to be probed at Jamestown
Making better use of soil moisture and nitrogen will be a major focus of the Grains Research and Development Corporation (GRDC) Update at Jamestown on August 19. GRDC Southern Regional Panel chair David Shannon said improving efficiencies in the use of moisture and nutrients was an important investment for the GRDC and keenly sought by growers in South Australia’s Mid North. “While the ...

Soil carbon storage is not always influenced by tillage practices
The practice of no-till has increased considerably during the past 20 yr. Soils under no-till usually host a more abundant and diverse biota and are less prone to erosion, water loss, and structural breakdown than tilled soils. Their organic matter content is also often increased and consequently, no-till is proposed as a measure to mitigate the increase in atmospheric carbon dioxide ...

Improving livelihoods for poorer forest dwellers in Nepal
Community forestry in Nepal claims to be a successful model of participatory, community-based forest management, and there is considerable evidence that it is improving forest protection and regeneration. However, community forestry makes only a limited contribution to improving rural livelihoods. New research suggests that social factors may be limiting the access of poorer households to ...
