Economic Development Assistance Program grant to focus on aquaculture, agriculture and environmental technologies.
Following an intense study of agricultural ecosystems near Montreal, a new tool that enables the simultaneous analysis and management of a wide range of ecological services has been developed. Environmental management typically focuses on nature’s resources like food, wildlife and timber, but can miss hidden ecosystem services such as water purification, climate moderation and the regulation of nutrient cycling.
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.
