“#Fitness trackers, environmental sensors prototyped to improve survival in the lobster supply chain ” Credit: Ben Gutzler Miniature fitness trackers for lobsters and devices to monitor the quality of their shipping conditions are being prototyped as part of an initiative to reduce stress points and improve survival in the lobster supply chain for the Maine lobster…
“#Nitrogen fertilizers are not effective in reducing nitrous oxide emissions from drip-irrigated cotton fields” Credit: CC0 Public Domain Agriculture is the major source of greenhouse gas nitrous oxide (N2O) emissions. Application of polymer-coated urea and urease and/or nitrification inhibitor has the potential in reducing soil N2O emissions. Drip irrigation is an effective water-saving strategy for…
“#The quality of Nigerian home-grown rice is poor: Here’s why” A rice farm in Nigeria.
