Fertilizer use not always helpful in revegetation efforts
Companies and communities trying to restore vegetation on damaged northern landscapes should think twice about using fertilizer to stimulate growth according to new research published in the November issue of Arctic, Antarctic and Alpine Research. view more (2009-12-18)
Sustainable fertilizer: Urine and wood ash produce large harvest
Results of the first study evaluating the use of human urine mixed with wood ash as a fertilizer for food crops has found that the combination can be substituted for costly synthetic fertilizers to produce bumper crops of tomatoes without introducing any risk of disease for consumers. view more (2009-09-02)
Improving Swine Waste Fertilizer
Swine production generates large amounts of waste. While this waste contains nutrients that may serve as fertilizer when applied to agricultural fields, the ratio of nutrients in the waste is different than what a crop requires. view more (2008-07-09)
New fertilizer SRM can help control heavy metal content
A new reference material developed by the National Institute of Standards and Technology (NIST) can help the agriculture industry and state regulators monitor the concentrations of several potentially hazardous heavy metal contaminants in fertilizers. view more (2006-10-13)
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. view more (2008-10-02)
Fertilizers help Zimbabwean farmers to increase crop yields
A little bit of manure and fertilizer can considerably improve the perspectives of Zimbabwean smallholder farmers in semi-arid regions. Nitrogen availability was found to be the factor that most limited farmers' efforts to increase cereal yields. Dutch-sponsored researcher Bongani Ncube demonstrated this after four years of research on smallholder... view more... (2007-04-16)
Preventing Soil Erosion in Continuous Corn
With recent increase in the cost of energy and subsequent explorations into alternative energy sources, the increased harvest of corn residue for cellulosic ethanol production is likely in the future. view more (2009-01-13)
Brewing a blast-less fertilizer
Down in the green, rolling hills and farmlands around Lexington, Kentucky, Darrell Taulbee can be found mixing up a batch of his homegrown fertilizer. But he's not looking to grow a better Big Boy or distill a smoother bourbon, he tells us. view more (2007-09-06)
Switchgrass Produces Biomass Efficiently
A USDOE and USDA study concluded that 50 million U.S. acres of cropland, idle cropland, and cropland pasture could be converted from current uses to the production of perennial grasses, such as switchgrass, from which biomass could be harvested for use as a biofuel feedstock. view more (2009-11-24)
New use for human hair
Agricultural crop production relies on composted waste materials and byproducts, such as animal manure, municipal solid waste composts, and sewage sludge, as a necessary nutrient source. view more (2008-12-29)
A Little Nitrogen Can Go a Long Way
Varying the rate of crop production inputs such as fertilizer and seed makes intuitive sense, as farmers have long observed differences in crop yield in various areas of a single field. The availability of spatial yield information from combines equipped with yield monitors has provided a good resource for improved management. view more (2008-09-04)
Bangladesh to dramatically expand technology that doubles efficiency of urea fertilizer use
The Government of Bangladesh has announced that it will expand urea deep placement (UDP)-a technology that doubles the efficiency of urea fertilizer use-to almost 1 million hectares (ha) of rice land, reaching about 1.6 million farm families, in the coming boro or dry season. view more (2007-12-19)
Restoring seagrass beds: Is it for the birds?
Although most people consider bird droppings a nuisance, scientists at the Dauphin Island Sea Lab see them as a rich source of phosphorus, a natural fertilizer for grassbeds which have been destroyed by boat propellers. view more (2006-04-11)
Nutrients in water may be a bonus for agriculture
Agriculture producers may find they don't have to bottle their water from the Seymour Aquifer in the Rolling Plains to make it more valuable, according to Texas AgriLife Research scientists. view more (2008-11-25)
On-farm research shows farmers can use less nitrogen to save money and reduce environmental impact
Ongoing field trials since 2002 by a team that includes 16 farmers, Cornell researchers and Cornell Cooperative Extension field crops educators in 10 counties are showing the value of on-farm research. view more (2007-06-21)
How much nitrogen is too much for corn?
North Carolina State researchers recently discovered a test that quickly predicts nitrogen levels in the humid soil conditions of the southeastern United States. view more (2007-04-24)
Alternative farming cleans up water
Although the addition of nutrients to soil helps to maximize crop production, fertilizer can leach nutrients, polluting the water supply. view more (2007-07-20)
Biodiesel on the wing: A 'green' process for biodiesel from feather meal
Scientists in Nevada are reporting development of a new and environmentally friendly process for producing biodiesel fuel from "chicken feather meal," made from the 11 billion pounds of poultry industry waste that accumulate annually in the United States alone. view more (2009-07-23)
Antibiotic resistant bacteria found in fertilizer
Vancomycin resistant enterococci (VRE) have been found in sewage sludge, a by-product of waste-water treatment frequently used as a fertilizer. view more (2009-05-29)
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... view more... (2008-08-20)
