Hawaiian educators transform a professional development course to strengthen the teaching of environmental and agricultural science.
Rangelands—During the past century, food production in the United States has achieved a remarkable degree of efficiency and the cost of food has remained low, but some of the conditions that made such a system possible are changing. Rising human population, water shortages, and depletion of fossil fuels all threaten current food production systems. In short, the era of cheap food may well be coming to an end.
Can a computerized machine tend broccoli and lettuce in the fields? With automated cultivation assisting in the battle against weeds, vegetable growers may be able to reduce costs of herbicide and labor without diminishing the crop yield. A new study in Weed Technology examines the economic effectiveness of machine-vision guidance systems that help cultivators accurately till the soil between rows of vegetable crops.
What are the top research questions facing agriculture? Earlier this year, the American Society of Agronomy (ASA) sought out the opinions of its members and leadership to develop a Grand Challenge statement, key questions, and expected outcomes.
Combined mechanisms of transport have important applications—transport of nutrients across cell membranes in plants and animals, the aeration of agricultural soils, performance of chemical reactors, the design of membranes for desalting brackish water, and the design of clay membranes for retaining dangerous chemicals. In a recent article in Vadose Zone Journal, scientists show that the developers of popular models of diffusion have made invalid assumptions.
A 2-year field study in Mississippi evaluated the effect of nitrogen, growth stage (bud formation and flowering), and harvest time (first in mid-July, second beginning of October) on peppermint yields, oil content, and composition.
Food Safety Consortium research at the University of Arkansas Division of Agriculture closes in on how probiotics -- direct-fed microbials -- can be used to fight Salmonella in poultry.
Recent Food Safety Consortium-supported research at Iowa State University shows that antibiotics may be helpful in reducing the pathogen E. coli O157:H7 among swine.
WSU receives federal grant to target genetics of E. coli in cattle.
Scientists have known for a long time that plants grow differently when they are spaced closer together than farther apart. Scientists at the University of Wisconsin-Madison conducted field experiments to determine the effects of early-season light quality on corn productivity.
Some say the world's population will swell to 9 billion people by 2030 and that will present significant challenges for agriculture to provide enough food to meet demand, says University of Idaho animal scientist Rod Hill. Hill and Larry Branen, a University of Idaho food scientist, organized a symposium during the American Association for the Advancement of Science annual meeting Sunday to explore ways biotechnology could provide healthy and plentiful animal-based foods to meet future demands.
