The new Aquaculture Decision Support Tool (Aqua-DST) will facilitate informed decision-making for aquaculture expansion in the Upper Ayeyarwady River Basin of Myanmar. This includes the Kachin, Magway, Mandalay, Sagaing and Southern and Eastern Shan states/regions. The tool currently covers 37 townships in Myanmar. It incorporates multi-criteria assessments of climate hazards, aquaculture ...
Aquaintech Inc. (AITI) was the first company to successfully develop and market Bacillus spore tablets for use in aquaculture. PRO4000X, our lead tableted product, is widely used in hatcheries, RAS systems, shrimp and fishponds, reservoirs, and discharge and intake canals. PRO4000X was designed to target pond bottoms. AITI is pleased to announce the addition of the TWC Bio-Block (TBB) to its ...
‘New’ Pentair saw net sales rise by 7.2% year-on-year to $732 million in Q1 2018, with the Aquatic Systems division up 8%, Filtration Solutions up 9% (driven by strong growth in China), and Flow Technologies up 4.6%. ...
Ecotoxicity tests that are used to understand the impacts of chemical pollutants on aquatic organisms and ecosystems could be improved by including all life stages of the test animals. ...
But with no concomitant growth in systems or strategies for handling manure, much of the waste winds up in waterways and landfills, or volatilizes to the atmosphere. ...
“It’s important to know which microbes are being lost from soil,” says Acosta-Martínez, a soil microbiologist and biochemist at the USDA-ARS Cropping Systems Laboratory in Lubbock, TX, “because different microbes have different roles in soil ...
Visitors will also be inspired by splashes of color and textures of pitcher plants, blueberries, larch and a host of other species that grow naturally on bogs, while dogwood, rhododendron, azalea and other native woodland plants form a buffer for the aquatic system. "We want to show people that it's possible to have a beautiful garden without a lot of fuss, and ...
A byproduct of many agricultural systems, N2O is a potent greenhouse gas (GHG) with a heat-trapping potential more than 300 times that of carbon dioxide. ...
His study focuses on soil health and cropping systems. He is fluent in English, Spanish, and French. He participated in an internship in South Africa in summer 2011 and will spend a semester in Brazil in spring 2012. ...
Surface water quality is important for the proper function of aquatic ecosystems, as well as human needs and recreation. Pasturelands have been found to be major sources of sediment, phosphorus and pathogens in Midwest surface water resources. ...
To achieve this, a management support system that allows for site-specific evaluation of nutrient-production imbalances is needed. ...
The Journal of Environmental Quality covers various aspects of anthropogenic impacts on the environment, including terrestrial, atmospheric, and aquatic systems. The American Society of Agronomy (ASA) www.agronomy.org, is a scientific society helping its 8,000+ members advance the disciplines and practices of agronomy by supporting professional growth and ...
Scientists at USDA’s Agricultural Research Service and Penn State used computer simulated farms with the support of field research to compare the environmental impact and economic efficacy of using alternative manure application methods in farming systems. The techniques and practices being evaluated included broadcast spreading with and without incorporation by tillage, ...
Solids were removed from the manure slurry in a passive two stage lagoon system, which resulted in the liquid fraction containing less dry matter and a higher nitrogen to phosphorus ratio than whole manure. ...
These nutrients increase the amount of phytoplankton in the water, which depletes oxygen and kills fish and other aquatic creatures. While injecting animal manure slurry into the soil has been proven to be an effective way of reducing greenhouse gas emissions, there has been no research on the possibility of nutrients leaching from the soil and reaching waterways. ...

Stromberger is seeking additional funding from the Environmental Protection Agency in an effort to expand the research into the Great Plains region and to develop a system of management for soils that exhibit enhanced atrazine degradation. ...
Higher concentrations of hormones in waterways have been found to cause physiological and sexual impairment in fish and other aquatic species. However, a study from the University of Delaware that examined estrogen concentrations runoff from agricultural fields fertilized with chicken manure found that it is as much about the application of the manure as it is about the ...
