  • 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 ...

  • Nitrogen applied

    Combating soil erosion is a primary concern for agricultural producers in the United States, and many have incorporated conservation tillage systems in their effort to maintain a profitable crop output. Cover crops are an important tool in this cycle, and while it is known that using nitrogen fertilizers can increase these crops biomass, the resulting levels of nitrogen for the following cash ...

  • Nitrogen fertilizer works way into sea and destroys marine habitats - EC

    Substantial increases in the flow of nitrogen into the sea have raised concerns about marine pollution. New research shows that commercial fishing is playing an important, but now declining, role in transferring this nitrogen back onto land. Enormous amounts of nitrogen fertilizer are applied to agricultural land to increase crop productivity. However, the use of such fertilisers can be damaging ...

  • 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  ...

  • Soil nitrogen test measures microbial nitrogen

    Contrary to the prevailing view, cereal crops derive the majority of their nitrogen from the soil, not fertilizer. Soils differ considerably in microbial activities that determine nitrogen-supplying power, and these differences must be taken into account if nitrogen fertilizers are to be used efficiently. The Illinois Soil Nitrogen Test (ISNT) was developed for this purpose, and involves ...

  • Fertilizers – a growing threat to sea life

    A rise in carbon emissions is not the only threat to the planet. Changes to the nitrogen cycle, caused in large part by the widespread use of fertilizers, are also damaging both water quality and aquatic life. These concerns are highlighted by Professor Grace Brush, from Johns Hopkins University in Baltimore, USA, in her historical review1 of landscape changes around Chesapeake Bay, a large ...

  • Nitrogen recommendations based on crop reflectance

    Nitrogen fertilizer is usually applied in greater quantities to corn than almost any other crop. But when it’s applied in excess of requirements, loss of the excess fertilizer to the environment can contribute to degraded water quality. One of the challenges to making an appropriate nitrogen fertilizer recommendation is the potential variability in soil nitrogen availability that may occur ...

  • Dangerous nitrogen pollution could be halved

    The most important fertilizer for producing food is, at the same time, one of the most important risks for human health: nitrogen. Chemical compounds containing reactive nitrogen are major drivers of air and water pollution worldwide, and hence of diseases like asthma or cancer. If no action is taken, nitrogen pollution could rise by 20 percent by 2050 in a middle-of-the-road scenario, according ...

  • Hydrolyzed fish fertilizer tested in organic vegetable production

    In the production of organic vegetables, nitrogen is important, yet can be quite costly to manage. Nitrogen management is even more challenging when production practices call for the use of polyethylene mulch combined with fertigation. The authors of a new study published in HortScience have found that hydrolyzed fish fertilizer holds promise as an "economically feasible" nitrogen source for ...

  • Less nitrogen could increase profit & sustainability

    More fertilizer doesn't always mean more profit. That's one conclusion from a 10-year study conducted by Agricultural Research Service (ARS) scientists at the agency’s Soil Plant Nutrient Research Unit in Fort Collins, Colo., and colleagues at Colorado State University. From 1998 to 2008, the researchers evaluated and compared potential management strategies for reducing nitrogen and nitrate ...

  • A new innovative way to fertilize through leaves

    Various nitrogen sources were tested in this study in order to fertilize pine leaves and oak leaves instead of using the traditional fertilization which is based on the nitrogen absorption through the root.
