  • Soil and crop management and carbon sequestration

    Research results from management scenarios ranging from those in the South Eastern, Great Plains, and Upper Midwest regions of the US and from Italy are reported in the March-April, 2010 issue of the Soil Science Society America Journal. This group of papers originated from the Soil Carbon Sequestration and Greenhouse Gas Mitigation Symposium that was held jointly by the Soil Science Society of ...

  • Crop management to reduce biofuels` carbon debt

    It is widely considered that using biofuels produces less greenhouse gas (GHG) emissions than using fossil fuels. However, there are concerns that the possible effects of land use change (LUC) may outweigh these benefits. New research looks at the effects of sustainable crop management as a means of reducing the negative impacts of LUC. Biofuels form an important part of the EU's strategy for ...

  • Impacts of tillage on soil and crops

    The increasing popularity of reduced tillage on crops has not only been an important development in combating soil erosion, but it has also been associated with increasing organic material and producing high crop yields. For peanut crops, however, reduced tillage has not gained a large acceptance as a viable practice, as findings of inconsistent yields have not encouraged farmers to make a switch ...

  • Soil phosphorus in an organic cropping system

    Phosphorus is a nonrenewable resource, raising concerns that agricultural practices may deplete reserves. (For one overview discussion of phosphorus, see Phosphorus Famine: The Threat to Our Food Supply in the June 2009 Scientific American.) Organic farming with low phosphorus  inputs can result in deficient levels of plant-available phosphorus (available-P).A group of researchers from ...

  • Cover Crops Add to Farm Sustainability

    A potentially record-setting U.S. corn harvest is underway. Many farmers can attribute the use of cover crops as one of multiple best management practices (BMPs) that help them increase yield year after year. Combined with BMPs of The Fertilizer Institute’s 4R Nutrient Stewardship program that promotes the application of nutrients at the right source, right rate, right time and right place, ...

  • Reality check for `miracle` biofuel crop

    The hardy jatropha tree as a biofuel source may not be the panacea for smallholders that some have claimed, say Miyuki Iiyama and James Onchieku. It sounds too good to be true: a biofuel crop that grows on semi-arid lands and degraded soils, replaces fossil fuels in developing countries and brings huge injections of cash to poor smallholders. That is what some are claiming for Jatropha curcas, ...

  • Yield projections for Switchgrass as a Biofuel Crop

    While scientists have conducted numerous studies on production of biomass from biofuel crops, such as switchgrass, no one has yet compiled this information to evaluate the response of biomass yield to soils, climate, and crop management across the United States. A team of researchers from Oak Ridge National Laboratory and Dartmouth College published just such a study in the July-August 2010 ...

  • Basic food crops dangerously vulnerable

    In the case of wheat, for instance, as a deadly new strain of Black Stem Rust devastates harvests across Africa and Arabia, and threatens the staple food supply of a billion people from Egypt to Pakistan, the areas where potentially crop and life-saving remnant wild wheat relatives grow are only minimally protected. “Our basic food plants have always been vulnerable to attack from new strains of ...

  • Preventing rangeland erosion: Developing better management practices in Iran

    The rangelands of Iran have one of the world’s longest history of agriculture development, with a deep tradition of technological developments and knowledge of the soil that has produced centuries of fertile crops. Currently, however, new pressures to feed an increasing population of humans and livestock in the region has taken its toll on the land, as evidence now suggests that the soil is ...

  • Crop performance matters when evaluating GHGs

    Measuring the emission of greenhouse gases from croplands should take into account the crops themselves. That’s the conclusion of a study in the September-October issue of the Journal of Environmental Quality, which examined the impact of farm practices such as tillage on the greenhouse gas, nitrous oxide (N2O). Expressing emissions per unit of crop yield rather than on a more conventional ...

  • GWorkS-model simulates crop operations in greenhouses

    Wageningen UR Greenhouse Horticulture and Wageningen University, group Farm Technology developed a simulation model for labour in greenhouses. Global competition urges growers to continuously improve labour efficiency and to innovate  crop operations in order to control labour costs and to offer appealing jobs and healthy work conditions in greenhouses. Computer simulation was used to ...

  • National Survey on Cover Crops Seeks Farmer Participation

    Farmers are invited to share their thoughts on cover crops—whether or not they use cover crops themselves—in a national survey, now in its third year of collecting valuable data on the increasingly popular management practice. The results, which will be released this summer, will help growers, researchers, agricultural advisors, ag retailers and policymakers more effectively address ...

  • Paul Tracy elected to certified crop adviser board

    Dr. Paul W. Tracy of Columbia, MO, has been elected to the position of Vice-Chair on the International Certified Crop Adviser (ICCA) Board. He will begin his term in January 2011, and he will become chair in January of 2012. Tracy succeeds Russell Duncan of South Carolina, who will become Chair of the ICCA Board in January 2011. Tracy received a B.S. degree in agriculture from Montana State ...

  • Forage crop promising as ecologically friendly ornamental groundcover

    A new, ecologically friendly groundcover for warm-weather landscapes is on the horizon. Rhizoma peanut, a warm-season perennial native to South America, has been used almost exclusively as a forage crop in the United States since the 1930s, but a study in the July HortScience says the perennial has potential as an ornamental groundcover or turf alternative. "Rhizoma peanut is grown in U.S. ...

  • Squeezing more crop out of each drop of water

    Studies in China and Colorado by Agricultural Research Service (ARS) scientists and cooperators have revealed some interesting tactics on how to irrigate with limited water, based on a crop’s critical growth stages. Laj Ahuja, research leader at the ARS Agricultural Systems Research Unit in Fort Collins, Colo., and colleagues conducted the studies. As one example, with wheat in China, they found ...

  • Cardamom crops affect forests, studies say

    Cultivation of cardamom, a high value spice crop, can take a toll on evergreen forests in tropical countries, independent studies in Sri Lanka and India have shown. Apart from disturbing biodiversity, cardamom ...

  • Cassava`s huge potential as 21st Century crop

    Save and Grow, an environmentally-friendly farming model promoted by FAO, can sustainably increase cassava yields by up to 400 percent and help turn this staple from a poor people's food into a 21st Century crop, FAO said today. In a newly-published field guide detailing Save and Grow's applications to cassava smallholder production, FAO noted that global cassava output has increased by 60 ...

  • Coffee pest spreading to other crops in East Africa

    East Africa's horticulture could face a severe crisis due to 'species jump' — whereby a disease moves from a known host to new and unusual ones — affecting fruits, vegetables, and medicinal and ornamental plants. Researchers in Uganda have discovered that the Black Coffee Twig Borer, a devastating coffee pest, has crossed over from Robusta coffee to about 40 plant  ...

  • Governments Invest $7 Million into Crop Research

    Today Saskatchewan Agriculture Minister Lyle Stewart and Member of Parliament Kelly Block (Saskatoon-Rosetown-Biggar), on behalf of Federal Agriculture Minister Gerry Ritz, announced nearly $7 million in funding for 46 crop-related research projects. “Our Government is proud to support crop research projects that benefit Saskatchewan farmers through improved yields and disease ...

  • Pakistan needs a new crop forecasting system

    Pakistan's outdated crop yield forecasting system needs a revamp, says Ibrar ul Hassan Akhtar. Like most developing countries, Pakistan is staring at the spectre of food insecurity, with its food production out of sync with population growth. The food availability scenario is further ...
