  • Traditional rice helps beat soil salination

    Rohana Rosairo has hung a sprig of paddy rice over his front door, a good omen for prosperity from the first harvest he reaped a few weeks ago from a long unused field. Rosairo's field, across a dirt track from his home, was just a mass of weeds until April when he cleared the plot and planted seed paddy. 'My father used to grow rice here, but he stopped a long time ago,' he said. High salinity ...

  • Some but not all plants can defend themselves against disease on saline soil

    Some plants with resistance against a specific disease are also able to defend themselves effectively when they are stressed due to, for example, drought or saline soil. At the same time, the resistance of other plants no longer functions in these very same conditions. Although this had been assumed for some time, Wageningen scientist Christos Kissoudis is the first person to show why. As a ...

  • The importance of measuring and monitoring soil moisture

    Crop irrigation uses more than 70% of the world’s water, and thus, improving irrigation efficiency is decisive to sustain the food demand from a fast-growing world population.* In future measuring and monitoring soil moisture will get more and more important to meet the needs of an increasing demand for food. Eijkelkamp offers solutions with a wide range of ...

  • Improved soil water sensors aid in irrigation management

    Agriculture, a large user of water for irrigation, is under pressure to reduce water use. Increased urban population growth has created more competition for limited water supplies. While growers have used soil moisture probes to aid in irrigation management in the past, earlier probes required maintenance or were expensive or inadequate.  New electronic sensors have been developed that require ...

  • AUS$28.5m Govt funding for soil carbon projects

    The Rudd Government has announced more than AUS$28.5 million in funding to support 137 local and community groups with environmental and sustainable farming projects under Caring for our Country. Environment Minister, Peter Garrett and Minister for Agriculture, Fisheries and Forestry, Tony Burke, said grants of between AUS$80,000 and AUS$400,000 would assist catchment management bodies, farmer ...

  • 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 ...

  • Identifying future soil science research needs

    Soil is subjected to a growing number of human-caused dangers from contamination, urbanization, desertification, salinization, mismanagement, and erosion. The soil ecosystem provides services necessary to manage and maintain a healthy and stable planet. Soil is key to carbon sequestration, nutrient cycling, water purification, and waste treatment. The Soil Science Society of America (SSSA) has ...

  • Genetic change could make crops thrive on salty soils

    Scientists have genetically modified plants to tolerate high levels of salt — offering a potential solution to growing food in salty soils. The researchers inserted a gene to remove salt — in the form of sodium ions — from water taken up by the plant before it reaches the leaves, where it does most damage. The research was published in The Plant Cell this month (7 July). High salinity reduces ...

  • Global plans of action endorsed to halt the escalating degradation of soils

    Urgent action is required to improve the health of the world's limited soil resources and stop land degradation, so as to ensure that future generations have enough supplies of food, water, energy and raw materials, government representatives and experts meeting at FAO warned today. The Global Soil Partnership has endorsed a series of action plans ...

  • Greater focus on soil health needed to feed a hungry planet

    More attention to the health and management of the planet's soils will be needed to meet the challenge of feeding a growing world population while coping with climate change and increased scarcity of natural resources, FAO Deputy Director-General Maria Helena Semedo today told a group of leading soil scientists and research organizations gathered at the UN agency's Rome headquarters to mark World ...

  • World Soil Day hails symbiotic role of pulses to boost sustainable agriculture

    Soil and pulses can make major contributions to the challenge of feeding the world's growing population and combating climate change, especially when deployed together, according to Soils and Pulses: Symbiosis for Life, a new report by the UN Food and Agriculture Organization released on  ...

  • Soil science society of America announces 2010 award recipients

    The Soil Science Society of America (SSSA) will present the following 2010 Awards during their Annual Meetings on Oct. 31-Nov. 3 in Long Beach, CA, www.acsmeetings.org. Kirk Scheckel – Marion L. and Chrystie M. Jackson Soil Science Award. Kirk Scheckel is a research soil scientist in the National Risk Management Research Laboratory of ...

  • Free Software Lets You Use HydraProbe to Determine Soil Water Retention Curve

    The Soil Water Characteristics software is a hydraulic properties calculator, developed by the USDA and Washington State University. It estimates soil water tension, conductivity and water holding capability based on the soil texture, organic matter, gravel content, salinity, and compaction. The software is for Windows-based PCs and is available for free ...

  • Strategic organic matter throughput helps to build soil carbon and boost crop yields

    Potential improvement in crop yields and reduced greenhouse gas emissions were among the benefits of increased soil organic matter throughput according to the findings of a project funded by growers and the Australian Government through the Grains Research and Development Corporation (GRDC) and the Victorian Department of Primary Industries (DPI). The relationships between organic matter inputs ...

  • Scientists search for solutions to Iraq`s salty farmland

    The high level of salt threatening two-thirds of Iraq's irrigated farmland — as well as many other countries — is being targeted by a group of Iraqi and international researchers and policymakers. The Iraq Salinity Project aims to develop long-term strategies to manage salinity in central and southern Iraq. It is coordinated by the International Center for Agricultural Research ...

  • GRDC to advise farmers on overcoming subsoil constraints

    Workshops are being held in northern New South Wales and Queensland in July and August to help advisors and grain growers identify and manage the impact of subsoil constraints. These include sodicity, salinity, alkalinity, acidity, subsoil nutrient deficiencies and toxicities and soil compaction, and cost growers around $80/ha in forgone income across the region. The workshops have been ...

  • Helping canneries make better use of leftover water

    With the help of a well-stocked kitchen cupboard, a can opener, and a microwave oven, a steaming-hot bowl of your favorite tomato soup can be ready to savor in just minutes. For decades America's canneries have helped make soups—as well as vegetables, fruits, juices and other familiar foods—more convenient for us to enjoy. Now, Agricultural Research Service (ARS) scientists are helping canneries ...

  • Salt-tolerant wheat a breakthrough for better yields

    Australian scientists have successfully carried out field trials of a salt-tolerant durum wheat, boosting grain yield by 25 per cent in salty soils. Durum is one of the most widely grown cereals in the world, but in saline soils it is vulnerable to salt build-up in the leaves, which can hinder growth and reduce yields, threatening food security. The researchers at the University of Adelaide ...
