Courting nitrogen in cover crop, sweet potato pairings

American Society of Agronomy – Some relationships can be complicated. Take the one between sweet potato crops and soil nitrogen, for example. Too little nitrogen and sweet potato plants don’t grow well and have low yields. Too much nitrogen, however, boosts the growth of leaves and branches at the expense of storage roots. That also […]

A faba fix for corn’s nitrogen need?

American Society of Agronomy – Researchers have good news for growers. Farmers raising a nitrogen-hungry crop like sweet corn may save up to half of their nitrogen fertilizer cost. The key: using a faba bean cover crop. Faba bean is an ancient crop increasingly used as a cover crop. Cover crops are grown in the […]

Cover crops to mitigate and adapt to climate change

Penn State – Cover crops long have been touted for their ability to reduce erosion, fix atmospheric nitrogen, reduce nitrogen leaching and improve soil health, but they also may play an important role in mitigating the effects of climate change on agriculture, according to a Penn State researcher. Climate-change mitigation and adaptation may be additional, […]

Tips for improving organic soils

By Laura Rance OrganicBiz editor Fababeans are gaining ground in both organic and conventional cropping rotations because they are a good source of nitrogen for the soil and less susceptible to diseases that affect some of the other pulse crops. But soil scientist and consultant Jill Clapperton said farmers need to be ready for the […]

Boosting nitrogen in organic systems

By John Greig OrganicBiz staff  Agriculture and Agri-Food Canada researchers have validated what organic farmers have known for years — that cover crops reduce nitrogen loss and fix nitrogen for use in subsequent crops. However, they also have found that in order to support a corn-soybean-wheat rotation, more cover crops are needed. Xueming Yang, a […]
