  • Light and moisture competition effects on biomass of red clover underseeded to winter wheat

    Red clover (Trifolium pratense L.) use as an underseeded cover crop in winter cereals has declined due to inability of growers to consistently establish uniform stands. The objective of this study was to assess the effect of light and soil moisture competition on underseeded red clover establishment and end of season dry matter production. Field trials were conducted at multiple locations in 2005 ...

  • Spatial analysis of early wheat canopy normalized difference vegetative index

    Efficient use of real-time canopy sensors requires knowledge of the scale (resolution) of variation in the measured canopy property. Knowing the amount of needed optical data requires estimation of the optimal combination of physical sensor density (number of sensors along the applicator boom) and sensor output density (sensor readings per unit distance along the travel path). The objective of ...

  • Spatial analysis of early wheat canopy normalized difference vegetative index: determining appropriate observation scale

    Efficient use of real-time canopy sensors requires knowledge of the scale (resolution) of variation in the measured canopy property. Knowing the amount of needed optical data requires estimation of the optimal combination of physical sensor density (number of sensors along the applicator boom) and sensor output density (sensor readings per unit distance along the travel path).

  • Chemical composition of residue from cereal crops and cultivars in dryland ecosystems

    Cropping systems in the dryland farming region of eastern Washington State are dominated by winter and spring wheat (Triticum aestivum L.) and spring barley (Hordeum vulgare L.). Excessive levels of residue may be an obstacle in the adoption of conservation farming systems. Decomposition of cereal crop residues is associated with fiber and nutrient content, and growers have observed differences ...

  • Measuring grain protein concentration with in-line near infrared reflectance spectroscopy

    The advent of near infrared (NIR) on-combine sensors gives growers the opportunity to measure the grain protein concentration of wheat (Triticum aestivum L.) during harvest. A study consisting of three sequential experiments (laboratory bench, combine test stand, and field) was conducted to evaluate the performance of an in-line, NIR reflectance spectrometer, referred to as the ProSpectra Grain ...

  • Temporal yield variability under conventional and alternative management systems

    Year to year variation in yield is an inherent risk associated with crop production and many growers rely on intensive mechanical or chemical inputs to preserve crop yield in the face of fluctuating environmental conditions. However, as interest grows in alternative crop management systems which depend less on external inputs, determining the degree to which management systems can impact the ...

  • One crop, two ways, multiple benefits

    Nitrogen fixation is one of the best examples of cooperation in nature. Soil microbes – naturally occurring bacteria in the soil – work with plants to pull nitrogen from the air. They turn the nitrogen into a form the plant is able to use. In return, the plant lets the microbes eat some of the sugars it makes. Faba beans (also called fava beans) are one example of plants that work ...

  • Ethanol Fundamentals

    What’s Ethanol? Ethanol is an alcohol-based alternative fuel produced from crops such as corn, barley, and wheat or from 'cellulosic biomass' such as trees and grasses. Brazil and the US together account for nearly 70% of global ethanol production. Virtually all US ethanol requirements today are satisfied by domestic production. Today All gasoline vehicles are capable of operating on ...

  • Growing demand for soybeans threatens Amazon rainforest

    Some 3,000 years ago, farmers in eastern China domesticated the soybean. In 1765, the first soybeans were planted in North America. Today the soybean occupies more U.S. cropland than wheat. And in Brazil, where it spread even more rapidly, the soybean is invading the Amazon rainforest. For close to two centuries after its introduction into the United States the soybean languished as a curiosity ...

  • Lindsay Irrigation advances Watertronics AG Pump Stations case Study

    When AJ Ochoa, a fourth generation Othello, Wash. farmer pushed one button to start his new Watertronics® agricultural pump station, he became one of the first irrigators in the world to reap the benefits of a fully integrated pump and center pivot water control package. Even more important to Ochoa, he began realizing immediate and substantial reductions in energy, water and labor costs. ...

  • What is it about this soil that protects plants from devastating disease?

    Figuring out why certain soils keep plant parasites at bay could be a boon for agriculture around the globe Plants around the world are constantly under attack — often with big implications for humans. In the 1960s, millions of elm trees in Britain, France and the U.S. fell victim to Dutch elm disease, which clogs the vessels that carry life-giving water to the trees’ leaves. ...

  • California company closes the composting loop

    BEFORE we made our first ton of compost, we had already talked to farmers to determine what they needed in a soil amendment,” says Roger Van Der Wende, Vice President, Supermarket Division, Community Recycling & Resource Recovery, Inc. (Community) in Sun Valley, California. Considering the fastidious navigation the company has done to advance in a previously uncharted realm of resource ...

  • Building a Safe Pesticides Industry with Bioproducts and Biomethods

    Three publications on my desk are the motivating factors behind this issue’s Compost Users Forum. The first is our own Compost Science & Utilization (Summer, l999), a journal that reports research throughout the world dealing with the process and product of compost making. The initial report in this issue is titled: “Prospects for Composts and Biocontrol Agents as Substitutes for Methyl ...

  • The complex nature of GMOs calls for a new conversation

    An honest discussion of genetically modified organisms must move beyond narrow concepts of human health to the wider social and environmental impacts of engineered crops. The GMO debate is one from which I’ve kept a purposeful distance. For one thing, it’s an issue that has already garnered more than its fair share of attention. For another, when you consider that many ...
