  • Quality Organic Fertilizers & Soil Amendments at an Affordable Price

    Our health starts with our soil. If the soil in our farms and gardens is depleted of life because of chemical and fertilization, the food will be sterile and not healthy. They key to a healthy body, soul, and mind is organically grown food that is full of life. “When the things we put into our bodies are healthy, our bodies are able to utilize the nutrients with very little energy. This ...

  • The Importance of Soil Sampling – Liquid Fertiliser Tanks Store Fertilizer Efficiently

    The importance of soil sampling was reinforced by Farming Life this week. It stated that good productive soils are the foundation of any successful farm system and that the ability of soils to supply nutrients at a time and in an appropriate quantity for grass and crop can be key to determining productivity. Therefore, a farms ability to manage soil fertility levels should be a primary objective. ...

  • Ohio State Agronomy Workshop Jan. 19 to Focus on Soil Fertility

    Healthy soils are a key ingredient to produce strong crop yields, and understanding what nutrients your soils need is a fundamental step in that process, says an educator in the College of Food, Agricultural, and Environmental Sciences at The Ohio State University. Soil fertility is crucial to maximizing yield potential when growing crops, said Amanda Douridas, an Ohio State University Extension ...

  • Measuring calcium in serpentine soils

    Serpentine soils contain highly variable amounts of calcium, making them marginal lands for farming. Successful management of serpentine soils requires accurate measurement of the calcium they hold. Research published this month in the Soil Science Society of America Journal shows that multiple measurement techniques are needed to accurately measure calcium content in serpentine soils. To make ...

  • Writing an equation for soil success

    Soil isn’t one size fits all. It may look the same under your feet – but under a microscope, that’s a different story. A plant’s roots, tiny bugs – these things can tell one soil from another quite easily. Soil scientists typically measure different aspects of soil — how much air it contains, how well it retains water, heat, and more — to ...

  • Fertilization regimen reduces environmental impact of landscape palms

    Palms are an important part of the environment in subtropical and warm temperate climates. Palms' aesthetics and small "footprints" make them desirable in a variety of landscapes throughout the southeastern United States. Unfortunately, palms also have some of the highest nutrient requirements of any plants. Timothy Broschat, a scientist from the University of Florida's Fort Lauderdale Research ...

  • Past, present and future of soil sciences

    The Soil Science Society of America (SSSA) is reporting the results of a recent survey of trends related to the soil science profession. The results suggest that employment opportunities in soil and related sciences are increasing, and students, academics, and employers have a positive outlook for the future of soil science. Despite these positive findings, the survey identified areas to be ...

  • Scientists to map out earth`s soil

    Some of the answers to the world’s greatest challenges -- such as climate change, food security, and water scarcity -- lie right beneath our feet. Responding to these and other critical issues, a group of scientists from around the world have announced an ambitious new plan to digitally map the Earth’s soil and its properties. Scientists, industry leaders, and government officials gathered ...

  • Satellites help map soil carbon flux

    Changes in soil carbon occur with changes in land management. Scientists at Oak Ridge National Laboratory and the University of Tennessee investigated quantifying soil carbon changes over large regions. They integrated remote sensing products with a national carbon accounting framework in a project funded by the U.S. National Aeronautics and Space Administration, Office of Earth Science. Results ...

  • FAO launches new global soil database

    A new database on the world’s soils improves knowledge of the current and future land productivity as well as the present carbon storage and carbon sequestration potential of the world’s soils. It helps to identify land and water limitations, and assist in assessing the risks of land degradation, particularly soil erosion risks, said FAO this week. Derived from the soil database, FAO has produced ...

  • Detailed soil information for Africa now available

    Zoom in on an African village, and see whether the soil is clayey or sandy, or how much nutrients or organic carbon it contains. This is now possible since ISRIC and partners have launched detailed freely accessible soil property maps for Africa. The maps, that can be explored in Google Earth, contain predictions of more than 20 soil properties at six standard depths at 250 meter ...

  • Improved soil water sensors aid in irrigation management

    Agriculture, a large user of water for irrigation, is under pressure to reduce water use. Increased urban population growth has created more competition for limited water supplies. While growers have used soil moisture probes to aid in irrigation management in the past, earlier probes required maintenance or were expensive or inadequate.  New electronic sensors have been developed that require ...

  • When it comes to forest soil, wildfires pack one-two punch

    For decades, scientists and resource managers have known that wildfires affect forest soils, evidenced, in part, by the erosion that often occurs after a fire kills vegetation and disrupts soil structure. But, the lack of detailed knowledge of forest soils before they are burned by wildfire has hampered efforts to understand fire’s effects on soil fertility and forest ecology. New research ...

  • Analyzing long-term impacts of biofuel on the land

    The growing development and implementation of renewable biofuel energy has considerable advantages over using declining supplies of fossil fuels. However, meeting the demands of a fuel-driven society may require utilizing all biofuel sources including agricultural crop residues. While a useful biofuel source, crop residues also play a crucial role in maintaining soil organic carbon stock. This ...

  • Finding the real potential of no-till farming for sequestering carbon

    The potential of no-tillage (NT) soils for increasing the soil organic carbon (SOC) pool must be critically and objectively assessed. Most of the previous studies about SOC accrual in NT soils have primarily focused on the surface layer (<20-cm soil depth), and not for the whole soil profile. The lack of adequate data on the SOC profile is a hindrance to conclusively ascertain the effects of ...

  • Tillage and reduced-input rotations affect runoff from agricultural fields

    A new study from researchers at the USDA Agricultural Research Service provides information about runoff under different management practices and can help farmers choose the practice that is best for them. No-till management practices can reduce soil erosion, but evidence suggests they can also lead to increased runoff of dissolved phosphorus from soil surfaces. Meanwhile, farmers looking ...

  • Nitrogen mysteries in urban grasslands

    Areas of turf-forming species created and maintained by humans for aesthetic and recreational (not grazing) purposes, i.e. “urban grasslands” are an extremely common, but poorly studied ecosystem type. There are over 150,000 km2of urban grasslands in the U.S. and many receive high rates of fertilizer, creating concerns about nutrient runoff to streams, lakes, and estuaries and emissions of ...
