Manure injection offers hope, challenge for restoring Chesapeake water quality

2/6/19

Widespread adoption by dairy farmers of injecting manure into the soil instead of spreading it on the surface could be crucial to restoring Chesapeake Bay water quality, according to researchers who compared phosphorus runoff from fields treated by both methods. However, they predict it will be difficult to persuade farmers to change practices.

Recruiting ants to fight weeds on the farm

Harvester ants that eat weed seeds on the soil's surface can help farmers manage weeds on their farms, according to an international team of researchers, who found that tilling less to preserve the ants could save farmers fuel and labor costs, as well as preserve water and improve soil quality.

'Scaring' soybeans into defensive mode yields better plants a generation later

11/13/18

By temporarily silencing the expression of a critical gene, researchers fooled soybean plants into sensing they were under siege, encountering a wide range of stresses. Then, after selectively cross breeding those plants with the original stock, the progeny "remember" the stress-induced responses to become more vigorous, resilient and productive plants, according to a team of researchers.
