  • Simulated Seawater Flooding Decreases Growth of Vegetable Seedlings

    Crop production in coastal areas is threatened by seawater intrusion, which increases soil salinity. Excessive salinity in soil and irrigation water, in combination with waterlogging, can significantly affect the growth and quality for agricultural crops, especially those vegetables that are sensitive to salinity. A new study determined salt-tolerant vegetable seedlings for coastal area ...

  • Gauging the impact of climate on U.S. agriculture

    Original story at MIT News To assess the likely impact of climate change on U.S. agriculture, researchers typically run a combination of climate and crop models that project how yields of maize, wheat, and other key crops will change over time. But the suite of models commonly used in these ...

  • CSIRO aiming to lead the world in agricultural modelling

    The joint venture has been formed to further develop the Agricultural Production Systems Simulator (APSIM) – a computer simulation model which takes into account many of the factors affecting a farm’s success, including different plant, soil and management approaches, to inform on-farm management decisions. APSIM has a broad range of applications including: farming systems design, assessment of ...

  • How much water is used for irrigation in European agriculture?

    Agriculture plays a large role in the management of water in the EU. However, there is little consistent information on water use in irrigation. New EU supported research has estimated how much water is used for irrigation in European countries, providing a framework to analyse agricultural pressures on water quantity. Water scarcity is an increasing problem in the EU and the situation is ...

  • Climate impact on agriculture could lead to calamity

    New research predicts that climate change will transform agriculture, with a drop in yields of up to 18% by 2050 in terms of calories harvested. By then, the global population will have risen by more than 18%, so the consequences could be calamitous. That’s the worst projected outcome. By the same date, the researchers say, yields in terms of calories could have risen by 3%, but that would ...

  • Climate change to shift global spread and quality of agricultural land

    New areas of land suitable for agriculture will open up under climate change’s effects, new research predicts, particularly in far northern regions of the world. However, the overall quality of land for farming will decline and many regions, including Europe, could lose large areas of suitable land. Demand for agricultural products is expected to rise by 70–110% by 2050. This is ...

  • Interactive Center Brings Agriculture History, Innovation & Exploration to the Public

    The young and young at heart will be at home inside the IQhub, a 9500-square foot center for agriculture history, innovation and exploration. The facility features 23 museum-quality exhibits chronicling the changes in agriculture over roughly four-hundred years. Beginning with Squanto's interactions with the pilgrims and the contribution made when he taught them to plant seeds alongside fish for ...

  • Holistic study approach expands understanding of agricultural chemicals in the environment

    An understanding how environmental processes and agricultural practices interact to determine the transport and fate of agricultural chemicals in the environment is essential for effectively addressing the widespread degradation of surface and ground waters from past, present, and future agricultural activities. While considerable research has been conducted at field or smaller scales, the ...

  • OSU Agriculture Safety and Health Professionals Offer Grain Handling Safety Tips

    With grain harvest well underway statewide thanks to favorable weather conditions throughout the region, growers are reminded that taking extra precautions when handling grain can lessen the potential for injury. When working around grain storage facilities, incidents such as slips, trips, falls, severe trauma injuries, entanglement or engulfment can happen in a fraction of a second, said Kent ...

  • North Africa and the Middle East through to the year 2050: towards a greater dependence on agricultural imports

    The North Africa and Middle East region (NAME) currently suffers from one of the highest food dependence levels in the world. On 28 October 2015, INRA presented the results of a study, commissioned by Pluriagri*, which was able to simulate the potential trajectories of the region's agri-food system between now and 2050. Based on a retrospective analysis (1961-2012), the experts (agronomists, ...

  • Integrating animal and crop production can reduce nutrient leaching from agricultural fields

    Nutrient leaching, the movement of plant nutrients from soil to water, can have negative effects on aquatic ecosystems due to eutrophication, which reduces the oxygen available in water, causing species and habitat loss. Ecological Recycling Agriculture (ERA), which is based on ecological principles and integrates crop production and animal husbandry, may limit this effect. This study ...

  • 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 ...

  • 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 ...

  • Identifying pollution hotspots in the landscape

    Water pollution due to excess sediment and nutrients is a serious problem in the U.S. Billions of taxpayer dollars are spent each year on conservation programs to reduce agriculture’s contribution to this pollution. The vast majority of agricultural conservation subsidies are given to the first qualified landowner who requests them, although it is widely recognized that some portions of the ...

  • Tracking phosphorus runoff from livestock manure

    Nutrient runoff from livestock manure is a common source of agricultural pollution. Looking for an uncommon solution, a team of scientists has developed an application of rare earth elements to control and track runoff phosphorus from soils receiving livestock manure. In addition to reducing the solubility of phosphorus, this method shows particular promise for researchers interested in tracking ...

  • America`s Emerging Bioeconomy

    AMES, Iowa, August 30, 2007 (ENS) - Robert Anex wants to know what would happen if the increasing demand for ethanol prompts American farmers to decide against crop rotation and plant corn on the same fields, year after year. This spring farmers responded to the ethanol industry's demand for grain by increasing their corn acreage by 19 percent over last year, according to U.S. ...

  • Analyzing long-term impacts of biofuel on the land

    The growing development and implementation of renewable biofuel energy has considerable advantages over using declining supplies of fossil fuels. However, meeting the demands of a fuel-driven society may require utilizing all biofuel sources including agricultural crop residues. While a useful biofuel source, crop residues also play a crucial role in maintaining soil organic carbon stock. This ...

  • Tool helps farmers anticipate their future climate

    Marginalised farmers in the developing world may soon be able to 'see' into the future through a tool that will help them adapt to climate change by simulating how their crop production will be affected 20 years from now. The open ...
