  • 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 ...

  • New Tool Offers Growers Easy Option to Measure Soil Organic Matter Content

    Researchers with Ohio State University's College of Food, Agricultural, and Environmental Sciences have developed a new tool that allows farmers to easily predict soil organic matter content and can help them make decisions about whether or not to sell crop residue. The tool can benefit growers by providing information for more timely planting and harvesting, reducing operating costs, increasing ...

  • Soil biodiversity: functions, threats and tools for policy makers

    Human societies rely on the vast diversity of benefits provided by nature, such as food, fibres, construction materials, clean water, clean air and climate regulation. All the elements required for these ecosystem services depend on soil, and soil biodiversity is the driving force behind their regulation. With 2010 being the International Year of Biodiversity and with ...

  • Global warming changing organic matter in soil

    New research shows that we should be looking to the ground, not the sky, to see where climate change could have its most perilous impact on life on Earth. Scientists at the University of Toronto Scarborough have published research findings in the prestigious journal, Nature Geoscience, that show global warming actually changes the molecular structure of organic matter in soil. 'Soil contains more ...

  • A little nitrogen can go a long way

    Varying the rate of crop production inputs such as fertilizer and seed makes intuitive sense, as farmers have long observed differences in crop yield in various areas of a single field. The availability of spatial yield information from combines equipped with yield monitors has provided a good resource for improved management. So, optimizing inputs to match yield potential of different areas ...
