Do urban 'heat islands' hint at trees of future?
City streets can be mean, but somewhere near Brooklyn, a tree grows far better than its country cousins, due to chronically elevated city heat levels, says a new study. View More (2012-04-25)
Use less water, producing energy and fertilizer at the same time
Water is a valuable resource. New technologies are making it easier to handle drinking water responsibly, purify wastewater effectively and even recover biogas and fertilizer. Fraunhofer researchers will be showing how this is done at the Hannover Fair (23 - 27 April) in the House of Sustainability (Hall 2). View More (2012-04-19)

Strip-till improves soybean yield
Crop yield can be improved by ensuring adequate nutrient availability. But how should you place the fertilizer and what cropping system gives the best yields? View More (2012-04-13)
Fertilizer use responsible for increase in nitrous oxide in atmosphere
University of California, Berkeley, chemists have found a smoking gun proving that increased fertilizer use over the past 50 years is responsible for a dramatic rise in atmospheric nitrous oxide, which is a major greenhouse gas contributing to global climate change. View More (2012-04-03)
Nitrate in drinking water poses health risks for rural Californians
One in 10 people living in California's most productive agricultural areas is at risk for harmful levels of nitrate contamination in their drinking water, according to a report released today by the University of California, Davis. View More (2012-03-13)

Improved rainwater harvesting system promising
Ridge and furrow rainwater-harvesting (RFRH) systems with mulches were first researched in the flat, lowland, semiarid conditions of northwest China to improve water availability and to increase crop production. View More (2011-12-14)
Researchers gain insight into 100-year-old Haber-Bosch process
For the past 100 years, the Haber-Bosch process has been used to convert atmospheric nitrogen into ammonia, which is essential in the manufacture of fertilizer. View More (2011-11-14)
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. View More (2011-11-07)
Decline in dead zones: Efforts to heal Chesapeake Bay are working
Efforts to reduce the flow of fertilizers, animal waste and other pollutants into the Chesapeake Bay appear to be giving a boost to the bay's health, a new study that analyzed 60 years of water quality data has concluded. View More (2011-11-04)
Crop sensors outdo farmers at choosing nitrogen rates
Choosing how much nitrogen (N) to put on corn fields isn't something farmers take lightly. Many factors go into the decision, including past experiences, the timing of application, yield goals, and results from soil tests. View More (2011-11-01)
Stalemate over organic farming slows progress in effort to combat food insecurity in Central Africa
The polarized debate over the use of organic and inorganic practices to boost farm yields is slowing action and widespread farmer adoption of approaches that could radically transform Africa's food security situation, according to a group of leading international scientists meeting in Kigali this week.
