  • Simulating the Effect of Climate Change on Agriculture

    Increased atmospheric CO2 levels and climate change are believed to contribute to extreme weather conditions, which is a major concern for many. And beyond extreme events, global warming is also predicted to affect agriculture.1,2 While climate change is expected to affect agriculture and reduce crop yields, the complete ...

  • Strengthening the world’s long term soil research base

    Imagine the science of climatology, if long-running weather stations were uncoordinated and operated independently with little cross-site comparison. Such is the present state of the long-term soils research base. The world’s long-term soil experiments are not well organized or even inventoried, and these studies are unknown to most scientists and to most of humanity. In the coming decades, ...

  • Weighing lysimeters for evapotranspiration research on clay soil

    Local crop evapotranspiration (ET) measurements are needed for northeastern Louisiana. Objectives were to install, calibrate, and assess soil water characteristics of paired weighing lysimeters at Saint Joseph, LA. Installed in 2005, the lysimeters have inner tanks 1.5 m long, 1.5 m deep, and 1.0 m wide that rest on load cells within outer tanks. The inner tanks contain refilled Sharkey clay ...

  • “Soil Health” And Compost

    In my quest to better understand how compost improves the chemical, physical and biological attributes of soil, I came across a training course created by the Rodale Institute, with support from the Northeast Region Sustainable Agriculture Research and Education (SARE) Program called “An Introduction to Soil Health.” The course emphasized that if we can improve the overall quality of ...

  • Arsenic in irrigated paddy soils

    Natural arsenic pollution of drinking water has been reported from over 70 countries world-wide, affecting an estimated 150 million people (Ravenscroft et. al., 2008). About 50 million of these people live in Bangladesh, 30 million in India and 33 million in six other countries of south and south-east Asia. It has recently been recognised that arsenic-contaminated groundwater used for irrigation ...

  • Sustainable Soil Health

    “A Nation that destroys its soil destroys itself.” – Franklin D. Roosevelt. We have learned some harsh lessons about how to treat our soil. While most of us are aware of the problems of the past, some agricultural operations in the world are not heeding those lessons. We all know that healthy soil is essential to feed the ever-increasing ...

  • Playing hide and seek below the soil

    Below the soil of a diverse grassland area you’ll find a jungle of plant roots. It is also home to a wide variety of bacteria and fungi, of which some are pathogenic and looking for a host in the tangle of roots. It appears that this is much more difficult when there is a larger diversity of plants as the host plant is more able to hide among the varied crowd. Greater plant diversity ...

  • Harvesting Corn Stover and Soil Quality

    Corn stover, left in fields after corn grain harvest, has been identified as a potential feedstock to help supply biofuel needed to offset a portion of the 14 million barrels of oils consumed daily by the U.S. transportation sector. It was projected to supply 256 million tons of the 1.4 billion tons of biomass (232 million Mg out of 1.3 billion Mg) estimated to be available each year. Corn stover ...

  • It is vital to reinvigorate organic farming research

    Organic farming can deliver food sustainably, but only with compelling science to boost its use, argues Ged Buffee. With increased yields and ecological stability becoming critical concerns for agricultural development, there's ...

  • Soils, souls and agricultural sustainability: the need for connection

    Sustainability is a contested term, and has much in common with justice and liberty in meaning very different things to different people. Typically it is the vision of the developed North that has dominated. This paper describes some of the results of a long-term research project based in Kogi State, Nigeria, designed to explore agricultural sustainability, and in particular how a Northern-based ...

  • Non-chemical Pre-plant Soil Disinfestation

    The battle with pests, diseases and weeds is an everyday problem for every farmer. Due to the fact that 40% of the world’s food production is lost due to pests and diseases, farmers need to manage crop protection. An excellent example of the need for pesticides is cotton. It is a crop that is affected by various pests. Cotton farming accounts for more than 25% of all insecticides and 12% of ...

  • Relationship between distribution uniformity and soil moisture content

    Tests on a sand-based green suggest that soil moisture measurements and hand watering are critical to mitigating localized dry spot. Providing a putting surface with uniform playing conditions and aesthetics is a critical component to successful golf course management. A condition that regularly disrupts putting green uniformity is localized drying or localized dry spot (also known as LDS) (3). A ...

  • Engaging High School students in soil science inquiry

    In April 2007, teacher Irka Elsevier and then-graduate student Biance Moebius-Clune began their second inquiry unit designed to enable high school students to better understand soil science concepts through their own research and experiments. Moebius-Clune was an NSF fellow in the Cornell Science Inquiry Partnerships (CSIP) program, which allowed the pair to develop inquiry curriculum to guide ...

  • An assessment of the suitability of backyard produced compost as a potting soil

    Current scientific knowledge of compost is largely derived from research into commercially produced green compost. This has shown that such compost tends to have high pH, high conductivity, and potential for organic and/or mineral pollutants and therefore can be problematic for use in growing media at high inclusion rates. Little work has been undertaken at an amateur composting scale and it is ...

  • Nitrous oxide emission from agricultural soils

    Anthropogenic nitrogen loading, particularly fertiliser usage in agricultural soils is thought to be a potentially important source of nitrous oxide (N2O) emission, which can be controlled by properly managed fertiliser usage. In this research, laboratory scale experiments were conducted to evaluate N2O production and emission from ...
