crop management system News

  • 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 ...

  • 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 ...

  • 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 ...

  • Energy crops and their environmental implications

    Interest in producing cellulosic ethanol from renewable energy sources is growing. Potential energy crops include row crops such as corn, perennial warm-season grasses, and short-rotation woody crops. However, impacts of growing dedicated energy crops as biofuel on soil and environment have not been well documented. This review article looks at the impacts of growing warm-season grasses and ...

  • Crop water use efficiency

    Crop water use efficiency (WUE), or yield per unit of water used, can be improved through irrigation management and methods, including deficit irrigation (irrigating less than is required for maximum yields) and supplemental irrigation (irrigating to supplement precipitation so as to avoid crop failure or severe yield decline). Thus, WUE is key for agricultural production with limited water ...

  • 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    Pakistan's outdated crop yield forecasting system needs a revamp, says Ibrar ul Hassan Akhtar.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 ...

  • Crop Protection China News 1014

    Crop Protection China News 1014 Gas leak at a factory in Nanjing, China, induced a disastrous explosion on 28 July. At least 10 people were killed and more than 100 were injured. High attention and awareness have been aroused by the accident and people could not help but think why so many chemical factories ...


  • Nitrogen recommendations based on crop reflectance

    Nitrogen fertilizer is usually applied in greater quantities to corn than almost any other crop. But when it’s applied in excess of requirements, loss of the excess fertilizer to the environment can contribute to degraded water quality. One of the challenges to making an appropriate nitrogen fertilizer recommendation is the potential variability in soil nitrogen availability that may occur ...

  • 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, ...

  • Food producers to benefit from innovative crop irrigation systems

    A four year research project led by Cranfield University aims to improve energy and water efficiency and crop quality through developing an innovative approach to irrigation practices. Rising energy costs, increasing water regulation and supermarket demands for premium quality produce are forcing growers to address the impacts of irrigation on crop quality whilst simultaneously reducing energy ...

  • Crop residues provide valuable protection for soil

    Removing wheat and sorghum crop residue after harvest, such as stalks, stubble and leaves, may cause more harm than good according to new research. Results indicate that removing residue can increase nutrient and sediment levels in water runoff, and decrease organic carbon stored in the soil. Crop residue left after harvest performs several ecosystem services. In particular it protects the soil ...

  • 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 ...

  • 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 ...

  • Potentially harmful effects of nanomaterials on soybean crops

    A new study has examined contamination of fully grown soybean plants by two nanomaterials – nano-cerium oxide and nano-zinc oxide. The results could be concerning, as they indicate that the nanomaterials are absorbed by plants, possibly affecting growth, yield, and the fixation of nitrogen in soil, an important ecosytem service. With the rapid expansion of nanotechnology, there is ...

  • 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 ...

  • 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 ...

  • In-crop nitrogen key to summer sorghum yields

    With the summer cropping season on our doorstep, growers are weighing up their planting options against the market, seasonal conditions and gross margin calculations. For many the summer cropping rotation will include sorghum and maximising crop yield and profitability will be a key driver of all pre-plant and in-crop agronomic decisions. Recent research funded by the GRDC, Queensland Alliance ...

  • Specialty Crops Focus of Feb. 7 Conference

    A conference for fruit and vegetable growers is set for Feb. 7 at the Oasis Conference Center, 902 Loveland-Miamiville Road in Loveland. The Southwestern Ohio Specialty Crop Conference offers “a little something for everyone,” said Greg Meyer, Ohio State University Extension educator in Warren County and event organizer. The ...

  • Sustainable crop protection - what’s around the corner?

    With sustainable usage likely to be a continued focus following the Brexit result, stringent safety criteria is only likely to increase the pressure on pesticide use in the UK, explains David Chandler from the Crop Centre at the University of Warwick. “We’ve experienced ten years of decline in the number of actives available to the industry, and products are not getting easier to ...

  • 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 ...
