  • 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 ...

  • 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 ...

  • Rice Farmers in China use Less Fertilizer, Increase Yield

    “Rice farmers can decrease their nitrogen fertilizer and pesticide use by around 20%, and increase their yield by 10% by using the ‘three controls technology’ (3CT),” says Dr. Xuhua Zhong, crop physiologist at the Rice Research Institute of the Guangdong Academy of Agricultural Sciences (GDRRI).  The meaning of “three controls” is controlling the amount of ...

  • 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, ...

  • Many Countries Reaching Diminishing Returns in Fertilizer Use

    By Lester R. Brown When German chemist Justus von Liebig demonstrated in 1847 that the major nutrients that plants removed from the soil could be applied in mineral form, he set the stage for the development of the fertilizer industry and a huge jump in world food production a century later. Growth in food production during the nineteenth century came primarily from expanding cultivated area. It ...

  • 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 ...

  • 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 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 ...

  • 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 ...

  • Greening Pepsi, from fertilizer to bottles

    Pepsi recently demonstrated its commitment to reducing its environmental impacts up and down the value chain with two rapid-fire announcements about new initiatives. The old-school approach to greening is to focus on operations within the proverbial "four walls." But Pepsi, like other leaders, is approaching sustainability more holistically, with much greater impact. I recently spoke with Tim ...

  • Fertilizer placement affects nutrient leaching patterns

    Controlled-release fertilizers (CRFs) are a widely used method of delivering nutrients to nursery container crops. The fertilizers contain encapsulated solid mineral nutrients that dissolve slowly in water, and are then released into substrates over an extended period of time. Although the use of CRFs is an accepted practice, growers and researchers are always looking for ways to decrease ...

  • 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 ...

  • New Material to Enhance Soils using Manure Waste

    The results of the research group of Valuation of resources from Universidad Politécnica de Madrid suggest an optimal solution to manage the manure from chicken and cattle. Biochar, a material obtained after thermal treatment of this waste through pyrolysis, is an organic fertilizer that applied in ...

  • Crop water use efficiency

    Crop water use efficiency (WUE), or yield per unit of water used, can be improved through irrigation management and methods, including deficit irrigation (irrigating less than is required for maximum yields) and supplemental irrigation (irrigating to supplement precipitation so as to avoid crop failure or severe yield decline). Thus, WUE is key for agricultural production with limited water ...

  • Three Subsidiaries of the World’s Largest Fertilizer Producer to Reduce Harmful Air Emissions at Eight Production Plants

    In a settlement with the United States, three subsidiaries of the Potash Corporation of Saskatchewan (PCS), the world’s largest fertilizer producer, will take steps to reduce harmful air emissions at eight U.S. production plants, the U.S. Environmental Protection Agency (EPA) and Department of Justice announced today. The settlement resolves claims that these PCS subsidiaries violated the ...

  • 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 ...

  • 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 ...

  • New strategy aims to reduce agricultural ammonia

    As concerns about air pollution from large dairies and other concentrated animal feeding operations (CAFOs) continue to mount, scientists are reporting a practice that could cut emissions of an exceptionally abundant agricultural gas—ammonia—by up to 30%. In the May-June 2011 issue of the Journal of Environmental Quality, a team led by Mark Powell, a soil scientist with the USDA ...
