  • 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 ...

  • 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  ...

  • 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 ...

  • 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 ...

  • Urine as a Commercial Fertilizer?

    The Bill & Melinda Gates Foundation supports joint project by Swiss aquatic research institute and South African water utility The separate collection of urine provides innovative opportunities for the improvement of sanitation and the recycling of nitrogen, phosphorus and potassium. Urine separation is an excellent sanitation solution, particularly in places where classic sewer-based ...

  • 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 ...

  • Bringing nitrogen out to pasture

    Cows in Brazil might start bellowing "leguuume" rather than "moo." That's because Jose Dubeux Jr. wants to plant more legume trees in cow pastures. Dubeux is an assistant professor of Agronomy at North Florida Research & Education Center. Growing up, Dubeux spent a lot of time on his grandparents' farm in Brazil. There he developed a passion for livestock operations and the grasslands on ...

  • 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 ...

  • 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 ...

  • 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. After assessing the efficiency of leaf nitrogen uptake of the two studied species, the researcher team from Universidad de Alcalá and Politécnica de Madrid concluded that this ...

  • 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 ...

  • Nitrogen use by warm-season grasses for biomass production

    Perennial, warm-season grasses are being evaluated as potential renewable energy crops. These species are well-suited for the production of biomass for energy applications because they utilize C4 photosynthesis and are perennial. Grasses that employ the C4 photosynthetic pathway use water, nitrogen (N), and solar radiation more efficiently than plants having the C3 pathway, and therefore are ...

  • 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 ...

  • EU Nitrogen Expert Panel presented to the European Parliament

    The “Forum on Fertilizers and Nutrients for Growth” took place in the European Parliament on the 9 December 2014. The meeting was chaired by Julie Girling (ECR, UK) alongside Vice-chairs Peter Jahr (EPP, Germany) and Jan Huitema (ALDE, the Netherlands) who together managed and contributed to a lively debate. Pierre Bascou, Director, DG Agriculture and Rural Affairs and member of the ...

  • Living mulch, organic fertilizer tested on broccoli

    Cover crops provide many benefits to agricultural production systems, including soil and nutrient retention, resources and habitat for beneficial organisms, and weed suppression. In regions where short growing seasons can hinder the establishment of productive cover crops between cash crop growing periods, living mulch systems may provide vegetable crop growers with opportunities to establish ...

  • Research to restore the fertility of earth`s soils

    In keynote addresses at the FAO Workshop on Sustainable Agriculture in Riyadh, Saudi Arabia on April 28 and April 29, 2009, soil fertility experts from the Nutrition Security Institute, (NSI) a non-profit organization located in Bellevue, Washington, presented advances and understandings in biotic soil fertility as a proven solution to the serious problems facing global agriculture. Their dual ...

  • 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 ...
