UF/IFAS Extension helps North Florida dairies move into grazing using a perennial grass
North Florida dairy farmers are increasing their use of grazing and hay areas thanks to the hybrid, perennial, warm-season Tifton 85 bermudagrass, tested extensively by the University of Florida’s Institute of Food and Agricultural Sciences’ Forage Extension and Research programs. Yoana Newman, an Extension Forage Specialist with the Agronomy department, described Tifton 85 as a ...

Utilisation of nitrogen and phosphate on dairy farms could be increased
Nitrogen and phosphate are important fertilisers. But excessive amounts often found in fields and pastures end up polluting the ground and surface water. Furthermore, dairy farmers are squandering their profits by wasting these expensive fertilisers. The Koeien & Kansen [Cattle and Opportunities] project set up by two PhD candidates from Wageningen University, part of Wageningen UR, shows how ...

Beast of a weed creeping across Midwest from south
It's a beast of a weed, creeping north into the Midwest from cotton country. Palmer amaranth can shoot up as high as 7 feet, and just one plant can produce up to a million seeds. Herbicide is increasingly futile against it, and the weed's thick stems and deep roots make it hard work to clear by hand. It can slash yields and profits when it gets out of control. Midwestern weed scientists are ...

Effects of chemical fertiliser and animal manure on soil health compared
Fertilising crops with cattle manure can lead to better soil quality than when synthetic fertiliser is used, recent research indicates. The use of cattle manure in the study led to greater soil fertility by encouraging higher microbial activity, and the researchers suggest that it could potentially improve soil’s ability to cope with periods of difficult growing conditions. The complex ...

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 ...

Household compost as good for soil as conventional fertilisers, say EU researchers
Since 2005, conventional disposal of organic waste has been prohibited in Sweden. Instead, this waste is incinerated or separated at source, processed (composted or anaerobically digested) and recycled as fertiliser on crop land. A new study has investigated the use of organic waste from different sources as a fertiliser and found that residue from biogas production is an effective fertiliser. ...

MIT Energy Initiative announces first seed grant winners for energy research
From harnessing microbes to developing new materials, from curbing pollution to harvesting wasted watts, a wide variety of MIT research projects in solar technology, climate change impacts and power transmission were among those chosen to receive more than $1.6 million in the MIT Energy Initiative's (MITEI) first round of campus seed grants. The grants, which range from $30,000 to $150,000 and ...
