  • Effects of chemical fertiliser and animal manure on soil health compared

    Fertilising crops with cattle manure can lead to better soil quality than when synthetic fertiliser is used, recent research indicates. The use of cattle manure in the study led to greater soil fertility by encouraging higher microbial activity, and the researchers suggest that it could potentially improve soil’s ability to cope with periods of difficult growing conditions. The ...

  • Sensor-based Irrigation Systems Show Potential to Increase Greenhouse Profitability

    Wireless sensor-based irrigation systems can offer significant benefits to greenhouse operators. Advances in sensor technology and increased understanding of plant physiology have made it possible for greenhouse growers to use water content sensors to accurately determine irrigation timing and application rates in soilless substrates. The wireless sensor systems provide more accurate measurements ...

  • Merry Christmas and a successful New Year!

    Learning is a life-long process, but in some countries not everybody achieves the minimal education to cope with the challenges of daily life. Being able to read, write and calculate budgets provides individuals with the opportunity to understand the instructions for using seed and fertilizers, avoid signing misleading contracts with money-lenders, and to open a bank account. According ...

  • Crop management: how small do we go?

    The use of on-the-go crop and soil sensors has greatly increased the precision with which farmers can manage their crops. Recently released research in Agronomy Journal questions whether more precise management is necessarily more efficient. They discovered that the law of diminishing returns applies to precision agriculture, calculating how large of an application area is optimal for precision ...

  • New software helps farmers manage nutrients

    University of Missouri Extension has released a new Web-based application to help farmers manage soil nutrient needs on farms. Nutrient management helps farmers set rates and timing of fertilizer applications, said John Lory, MU Extension nutrient management specialist. Plans are required for some farms in cost-share programs and permitted animal feeding operations. The free MMPTracker tool is ...

  • UF/IFAS researchers use pigs to root out problem weeds

    Sometimes, the old-fashioned ways are the best ways. Back before chemical pesticides and herbicides, farmers had to come up with ways to kill the weeds that took over their fields. One method used “back in the day” was letting pigs loose in fields that were not being used for crops for a season and allowing the pigs to do what they do naturally: dig up the roots of weeds and ...

  • Study probes sources of Mississippi river phosphorus

    In their eagerness to cut nitrogen and phosphorus pollution in the Mississippi River and Gulf of Mexico, people have often sought simple explanations for the problem: too many large animal operations, for instance, or farmers who apply too much fertilizer, which then flows into waterways. But according to new modeling research that examined phosphorus loading from all 1768 counties in the ...

  • Crop performance matters when evaluating GHGs

    Measuring the emission of greenhouse gases from croplands should take into account the crops themselves. That’s the conclusion of a study in the September-October issue of the Journal of Environmental Quality, which examined the impact of farm practices such as tillage on the greenhouse gas, nitrous oxide (N2O). Expressing emissions per unit of crop yield rather than on a more conventional ...

  • Bion Announces Kreider Farms Project Sampling Results

  • Life cycle study demonstrates the long-term costs of everyday crops

    The environmental and economic costs of a selection of common crops have been determined by a new study, which hopes to improve agricultural sustainability assessments in Europe. The researchers used life cycle analysis on organically farmed tomatoes and pears, and intensively farmed wheat, apples, and lettuce to show the overall impact of agricultural methods. Agriculture accounts for 45% of ...

  • Simple method to estimate soil carbon stocks in grassland

    Storage of carbon in soil helps to keep land fertile and regulates the climate, and is therefore an important ecosystem service. However, mapping of soil carbon stocks currently uses unreliable measures. This study used data from a national survey of English grasslands to show that soil carbon stocks can be accurately predicted using simple measures of soil and climatic conditions. Two to three ...

  • New ORNL tool gets handle on cropland CO2 emissions

    For the first time, farmers have data that tracks at the county level on-site and off-site energy use and carbon dioxide emissions associated with growing crops in the United States.
