Through their research, scientists developed thresholds of impervious surface around planting sites. In other words, they defined points at which the amount of pavement around a tree reduces its condition. Using these established levels of impervious surface, landscape architects and other landscape professionals can plant trees in a way that reduces pest damage and economic loss.
The Q-biotype whitefly, a significant tropical and subtropical pest, may threaten Florida crops such as tomatoes, squash, beans, watermelons and many other vegetables and ornamentals if immediate measures are not taken to prevent its spread.
Most U.S. homes are full of familiar household products with an ingredient that fights bacteria: triclosan. Most of the triclosan is removed in waste water treatment plants. However, a U.S. Geological Survey found the antibacterial in nearly 58% of freshwater streams. What does that mean for the food and soil irrigated with water from streams?
As Iowa farmers have planted more acres of corn to meet the demand driven by the corn-based ethanol industry, many models predicted that nitrate concentrations in Iowa streams would increase accordingly. However, recent IIHR research based on water monitoring and published in the Journal of Soil and Water Conservation casts doubt on these predictions.
A breakthrough by an Australian collaboration of researchers could make infra-red technology easy-to-use and cheap, potentially saving millions of dollars in defence and other areas using sensing devices, and boosting applications of technology to a host of new areas, such as agriculture.
Don't eat the core, it's poisonous: it's something parents often say to their children before they eat their first peach. Peach pits, which are hidden inside the nut-like husk, do in fact contain amygdalin, a substance which can degrade into hydrogen cyanide in the stomach.
Massive amounts of data require infrastructure to manage and store the information in a manner than can be easily accessed for use. In a paper published May 16, 2016 in Trends in Microbiology, DOE Joint Genome Institute researchers call for the formation of a National Microbiome Data Center to efficiently manage the datasets accumulated globally.

Emissions from farms outweigh all other human sources of fine-particulate air pollution in much of the United States, Europe, Russia and China, according to new research. The culprit: fumes from nitrogen-rich fertilizers and animal waste combine in the air with combustion emissions to form solid particles, which constitute a major source of disease and death, according to the new study.
A team of experts from the Weed Science Society of America found that if weeds were allowed to grow with no control measures, about half of corn and soybean crops across the United States and Canada would be lost, costing growers about $43 billion annually. The team was led by Kansas State University agronomy professor, Anita Dille.
In the basic water cycle, water falls on the land in some type of precipitation (rain or snow). It either is soaked into the ground or runs off into a body of water – storm water or natural. Eventually, it returns to the atmosphere. But the story about water movement in soil is complex. Soil scientists call this topic “soil hydrology.” The Soil Science Society of America (SSSA) May 15 Soils Matter blog post explains how soil texture, soil structure, and gravity influence water movement.
