  • Agronomy journal turns one hundred

    During 2008 we celebrate the centennial anniversary of Agronomy Journal. Many people have certainly been influenced in some way by the science published during the 100-yr existence of the journal. From Volume 1 up through Volume 98 (2006) there have been more than 30,290 authors who published 15,232 articles totaling 89,056 pages. More than 2545 editors were required to review and edit the papers ...

  • Countryside Coop Opens the Durand Agronomy Facility

    Countryside Coop needed a new plant on the banks of the Chippewa River in Durand, WI. They chose Waconia Manufacturing to provide the receiving and blending equipment. “We were happy with the towers at other locations. In the past WMI has been very reliable and permitted very few challenges”, said Mike Christianson, the Agronomy Division Supervisor for Countryside Coop. He explained ...

  • After 10,000 years of agriculture, whither agronomy?

    The evolution of agriculture within the last 11,000 yr marked the first major inflection point in food yield and changed forever the character of the human condition. The application of technology to agriculture early in the 20th Century induced the next major crop yield inflexion point. Identifying the technological wellspring from which increased rates of productivity will be obtained in the ...

  • 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 ...

  • Damatta Bio Farmer (Cezar Villela), Brazil - Case Study

    EFFECTS OF VARYING COVER CROPS ON SOIL RESPIRATION IN A BRAZILIAN OXISOL A Cover Crop/ Soil Respiration Study in Brazil: Validating gains in soil biology with Solvita CO2 – results after 1 growing season. Brazilian Oxisols are high in clay with low natural fertility. This poses a challenge for growers. To test the potential for soil improvement various grasses and legumes were grown for an ...

  • Assessing the cost, effectiveness and acceptability of best management farming practices: a pluri-disciplinary approach

    The AgriBMPWater project has been imagined and built in a pluri-disciplinary approach and framework, with the study of the object 'BMPs' using several disciplines at the same time (hydrology, economy, sociology, geography and agronomy). The knowledge of the object in each discipline is deepened by a fertile multi-field contribution: borders of disciplines have been broken down, allowing ...

  • Making sustainable intensification work on sound evidence

    Assessing the real-world impact of new agronomic practices depends on good economic studies, says David Spielman. A new narrative is slowly taking hold of today's collective thinking about productivity, growth and poverty reduction in developing-country agriculture: the concept of sustainable intensification. Sustainable intensification hinges primarily on practices and technologies that help ...

  • Assessing agroforestry`s advantages

    Agroforestry, the deliberate placement of trees into crop and livestock operations, can help capture substantial amounts of carbon on agricultural lands while providing production and conservation benefits. However, we currently lack tools for accurately estimating current and projected carbon values in these systems. In North America, windbreaks are an effective carbon-capturing option. Only ...

  • 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 ...

  • Model forecasts long-term impacts of forest land-use decisions

    The drive to develop crops for use as biofuel, continues to raise questions about additional uses of forest land. A cutting edge computer model developed at North Carolina State University offers detailed insight to predict the environmental impact – along with understanding forest ecosystem response to global climate change. “We think the model will help policy makers and forest ...

  • Genetically engineered flax: potential benefits, risks, regulations, and mitigation of transgene movement

    Flax (Linum usitatissimum L.) has been grown for more than 6000 years, primarily for oil and fiber. Advances in plant biotechnology have resulted in flax cultivars with increased herbicides resistance and there is potential to produce transgenic flax with seed oil containing fatty acids with nutraceutical properties. Flax oil is a rich source of -linolenic acid (ALA, 18:3cis9,12,15), a precursor ...

  • Effect of ethylene on fruits and vegetables rotting

    In the latest edition of Bioconservacion's Partner Meeting with all its partners from the post-harvest sector, we had the good fortune to have Professor Emeritus Ron Wills from the University of Newcastle in Australia. Dr Wills, with over 50 years experience researching agronomy, agriculture and post-harvest techniques is undoubtedly a leader in the sector and one of the great experts on ...

  • Understand Crop Nutrients to Optimize Farm Management

    Crop Nutrient Uptake and Removal Farming today is an increasingly complex business. However, when you break down the simplest function of agriculture, it’s all about nourishment. With the global population expected to reach nearly 10 billion by mid-century, nourishing your soil to meet this demand is increasingly essential to what you do. How often does crop nutrient uptake and removal ...

  • Effect of AgraGel T-400 on tomato crops, U. of Valparaiso, Chile - Case Study

    Introduction At present, a great part of vegetable production in Chile is dedicated to industrial agronomy and one of the most important products is the tomato crop for industrial processing. Chile has a capacity of 180,000 tons of tomatoes per year, which is equivalent to 12,000 hectares of crop land. Among canned products tomato paste represents 38%. This is an important employment generating ...

  • Training a New Generation of Sanitation Researchers

    SOIL loves providing opportunities for students in Haiti to work with our team and gain valuable hands-on experience in the sanitation sector to help jumpstart their careers. Over the past six months, SOIL research partner Dr. Rebecca Ryals has been conducting a study on optimal composting conditions at our waste treatment facilities. The study looks at whether using different lining materials ...

  • 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 ...

  • Free and Conjugated Estrogen Exports in Surface-Runoff from Poultry Litter–Amended Soil

    Land application of animal manures such as poultry litter is a common practice, especially in states with surplus manure. Past studies have shown that animal manure may contain estrogens, which are classified as endocrine-disrupting chemicals and may pose a threat to aquatic and wildlife species. We evaluated the concentrations of estrogens in surface runoff from experimental plots (5 × 12 ...

  • Wholesale arable change leads to tight slug control

    "Eight years into implementing a zero-till policy across the farm, we’re seeing improved yields of 10 tonnes per hectare for our first year wheat, and five tonnes per hectare on winter beans. We’ve also noticed that we continue to see year-on-year improvements to soil structure and crop yields. “The winter beans have been extremely valuable in the rotation to ensure nitrogen ...

  • A survey of factors involved in crop maturity

    The time necessary for crops to successfully complete reproduction is species and environment dependent. Lifecycles can be completed in a few weeks or take several years depending on the plant species. Crop development is divided into phenophases that are affected primarily by light and temperature changes, interacting with phytohormones. Some species are influenced more by light and others by ...
