Phosphorus is a crucial nutrient regularly applied to crops such as corn and soybeans to help them grow efficiently. However, excess phosphorus can be carried by rainwater runoff into lakes and streams, creating potential problems for aquatic environments and the ecosystem services they provide to humans.
A new strain of yeast that could improve the efficiency of making fuel from cellulosic biomass such as switchgrass has been discovered by researchers. Both the yeast strain and the method of its design could help overcome a significant bottleneck in the biofuels pipeline — namely, that the powerful solvents so good at breaking down biomass also sometimes hinder the … Read More
A low-cost method of removing phosphates from tile drainage water has been developed, and may help protect lakes and streams. Using steel byproducts to trap phosphates in simulated tile drainage water, the researchers envision installing a steel-containing cartridge as an add-on to nitrate-capturing bioreactors.
Although researchers and industry personnel have made recommendations to slow the evolution of herbicide-resistant weeds, an understanding of the patterns and causes of the resistance has been limited. A recently published study looking at glyphosate-resistant waterhemp is providing valuable evidence that points to management practices as the driving force behind herbicide resistance, and that herbicide mixing, as opposed to herbicide rotation, is the most effective tool in managing resistance.
