  • Life cycle study demonstrates the long-term costs of everyday crops

    The environmental and economic costs of a selection of common crops have been determined by a new study, which hopes to improve agricultural sustainability assessments in Europe. The researchers used life cycle analysis on organically farmed tomatoes and pears, and intensively farmed wheat, apples, and lettuce to show the overall impact of agricultural methods. Agriculture accounts for 45% of ...

  • 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 ...

  • The future of cover crops

    Winter cover crops are an important component of nutrient cycling, soil cover and organic matter content. Although its benefits are well documented, cover crop use in farming systems is relatively low. Research has shown that time and money are the two primary reasons why farmers are hesitant to adopt the technique. Developing innovative and cost-effective crop cover systems could increase the ...

  • Cover crops reduce erosion, runoff

    Cover crops may be more effective at reducing soil erosion and runoff after maize harvest than rough tillage, according to scientists from the Université Catholique de Louvain, in collaboration with the Independent Center for the Promotion of Forage (CIPF). The three-year study, supervised by Charles Bielders and conducted by Eric Laloy, measured erosion and runoff losses from silt loam ...

  • Forest fires help power the nitrogen cycle

    When fire burns down a forest, nitrate levels go up, and the effects are persistent, according to recent research from University of Montana scientists. They found that charcoal deposited during fire events has the potential to stimulate the conversion of ammonia to nitrates, an important step in the nitrogen cycle. Led by Patrick Ball, the research team found that a type of bacteria that ...

  • Soil carbon cycling and the global carbon balance

    Like most things that exist underground, plant roots are out-of-sight and easily forgotten, but while flowers, leaves, and other aboveground plant parts are more familiar, plant roots are equally deserving of our appreciation. Beneath every towering tree, tasty crop, and dazzling ornamental lies a root system that makes it all possible. Roots provide anchor and support for plants, extract water ...

  • Hawaii is genetically engineered crop flash point

    You can trace the genetic makeup of most corn grown in the U.S., and in many other places around the world, to Hawaii. The tiny island state 2,500 miles from the nearest continent is so critical to the nation's modern corn-growing business that the industry's leading companies all have farms here, growing new varieties genetically engineered for desirable traits like insect and drought ...

  • Rising heat hits Indian wheat crop

    Researchers in the UK have established a link between changing climate and agriculture that could have significant consequences for food supplies in South Asia. They have found evidence of a relationship between rising average temperatures in India and reduced wheat production, which was increasing until about a decade ago but has now stopped. The researchers, Dr ...

  • 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 ...

  • GM crops can thrive as climate warms

    Genetically engineering photosynthesis in plants could take advantage of rising global temperatures and increased levels of carbon dioxide, US scientists say. They believe this could achieve much higher yields on the same amount of land and help to stave off the prospect of widespread hunger as human populations increase. Researchers at ...

  • GM crops could reduce need for herbicides

    Analysis of large-scale European field trial data reveals that lower quantities of herbicides are applied to crops genetically modified for herbicide-resistance compared with conventionally grown crops. However, the data also suggest that biodiversity may be reduced if genetically modified (GM) crops are grown widely. Transgenic crops are currently grown in 22 countries across the world, ...

  • 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 ...

  • 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 ...

  • Some plants are more sensitive to herbicides during reproductive stages of life cycle

    This study assessed the effects of herbicides on non-target plants in Denmark and Canada. The findings showed that some plants are more sensitive to herbicides in the reproductive stages of their life cycle and can experience delays in flowering and reduced seed production. The authors say future ecological assessments should consider reproductive outcomes. Herbicides are some of the most widely ...

  • Kenyan Professor promotes indigenous crops to solve Africa’s food crises

    In Kenya, a devastating cycle of drought and flood reflects the worst that climate change has to offer. These and other more insiduous impacts of warming temperatures threaten the health and survival of the nation's poorest and most at-risk inhabitants, namely women and children. The average yearly income in Kenya is less than US$1,000, 60 percent of the population is below poverty level, and ...

  • In organic cover crops, more seeds means fewer weeds

    Farmers cultivating organic produce often use winter cover crops to add soil organic matter, improve nutrient cycling and suppress weeds. Now these producers can optimize cover crop use by refining seeding strategies, thanks to work by an Agricultural Research Service (ARS) scientist. In moderate climates, suppressing weeds in winter cover crops is important because weeds that grow throughout ...

  • Soil biodiversity reduces nitrogen pollution and improves crops’ nutrient uptake

    Increased soil biodiversity can reduce nitrogen pollution, improve nutrient uptake by plants and even increase crop yields, new research suggests. The two-year study found that levels of nitrogen leaching from soil with an abundant soil life were nearly 25% lower than for soil with a reduced level of soil life. Practices which enhance soil biodiversity such as reduced tilling, crop rotation and ...
