  • Nitrogen fertilizers` impact on lawn soils

    Nitrogen fertilizers from farm fields often end up in aquatic ecosystems, resulting in water quality problems, such as toxic algae and underwater ‘dead zones’. There are concerns that fertilizers used on lawns may also contribute to these problems. All of the lawns in the United States cover an area almost as large as Florida, making turfgrass our largest ‘crop’ and lawn ...

  • 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 ...

  • Soil and crop management and carbon sequestration

    Research results from management scenarios ranging from those in the South Eastern, Great Plains, and Upper Midwest regions of the US and from Italy are reported in the March-April, 2010 issue of the Soil Science Society America Journal. This group of papers originated from the Soil Carbon Sequestration and Greenhouse Gas Mitigation Symposium that was held jointly by the Soil Science Society of ...

  • Food security depends on sustainable nutrient management of soils

    Food security is being threatened by loss of soil nutrients that are essential for the high yield of crops. A recent study outlines strategies to ensure the sustainable production of food through a holistic approach to soil nutrient management. In response to the rising demand for food from an increasing world population, high-yielding crops are being grown with the help of artificial fertilisers ...

  • 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 ...

  • Fertilizer Use to Surpass 200 Million Tonnes in 2018

    Global fertilizer use is likely to rise above 200.5 million tonnes in 2018, 25 percent higher than recorded in 2008. World fertilizer consumption will grow by 1.8 percent a year through 2018, according to FAO's new report "World fertilizer trends and outlook to 2018." At the same time "the global capacity of fertilizer products, intermediates and raw materials will increase further," the report ...

  • 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 ...

  • Using organic fertilizers could protect against climate change

    Studies show that soil fertilized with organic materials, such as compost, could increase the amount of stored carbon and potentially help slow down greenhouse emissions. Applying organic fertilizers, such as those resulting from composting, to agricultural land could increase the amount of carbon stored in these soils and contribute significantly to the reduction of greenhouse gas emissions, ...

  • Smart farming technique to boost yields, cut fertilizer pollution

    Researchers at Lancaster University are using X-rays to help farmers increase yields and cut water pollution following an unexpected discovery in a pea and bean crop. Plant and Soil Scientists hope to combine two new technologies to provide a rapid "same day" measurement of soil phosphorus availability, enabling farmers and growers to make more informed decisions about fertiliser ...

  • What the Fertilizer Industry Has Been Doing to Reduce Groundwater Pollution

    The fertilizer industry is very concerned and engaged in the issue of nitrate contamination in California's groundwater supplies, according to Richard Cornett, communications director for the Western Plant Health Association in Sacramento, a trade group that represents fertilizer companies, manufacturers and retailers. Regarding a recent UC Davis study on the issue, the fertilizer industry ...


  • Using Liquid Manure to Fertilize Wheat? Consider Timing, Nitrogen Content

    Liquid livestock manure can be a great option as a spring top-dress fertilizer for wheat fields if applied during the appropriate window of time and if it has the right amount of nitrogen, according to research conducted by the College of Food, Agricultural, and Environmental Sciences at The Ohio State University. In a report published in the latest issue of the college’s  ...

  • New Manure Sidedress Method Lowers Fertilizer Costs, Increases Yields

    With corn needing nitrogen, and pigs and cattle producing a lot of it, anything that offers a better way to use their waste to fortify crops should intrigue farmers. Two agriculture experts at The Ohio State University have redesigned a metal tractor attachment so that it allows farmers to put manure on a field while crops are ...

  • Soil phosphorus in an organic cropping system

    Phosphorus is a nonrenewable resource, raising concerns that agricultural practices may deplete reserves. (For one overview discussion of phosphorus, see Phosphorus Famine: The Threat to Our Food Supply in the June 2009 Scientific American.) Organic farming with low phosphorus  inputs can result in deficient levels of plant-available phosphorus (available-P).A group of researchers from ...

  • Liquid corn, fish fertilizers `good options` for organic blackberry production

    Managing soil nutrients in organic production systems presents multiple challenges for fruit growers. The availability and release rate of nitrogen from organic fertilizers, ease of application, and cost are among the important factors that influence choices in organic production. The authors of a new study say that there has been limited information available about the influence of fertilizer ...

  • 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.
