Dairy farmers in the Northeast can improve water quality and boost the profitability of their operations by changing the timing and method of applying manure to their fields in the fall, along with planting rye as a cover crop between corn crops -- or by double-cropping rye and corn, according to Penn State researchers.
A new strategy being rolled out in China relies on the idea that farmers can harvest much more than crops. The idea is that well-managed, diverse agricultural lands can provide flood control, water purification and climate stabilization, among other valuable services.
A Virginia Tech professor was part of an international team of researchers that discovered new advances about the major ecological patterns driving the changes in soil biodiversity that occur over millions of years.
Crops just can't do without phosphorus. Globally, more than 45 million tons of phosphorus fertilizer are expected to be used in 2019. But only a fraction of the added phosphorus will end up being available to crops.
In south Florida, for example, "it is thought that less than twenty percent of phosphorus applied as fertilizer is taken up by plants before it becomes unavailable," says Mary Tiedeman, a researcher at Florida International University.
