The discovery by an international team of researchers will support breeding of crops with deeper roots, enabling them to acquire more nitrogen, says Penn State University.
The availability of nitrogen (N) returned to the soil from a cover crop for use by the following crop is a function of residual soil N and N mineralization but environmental factors make it difficult to predict the amount of N that will become available and when it can be used. A new post from the University of Nebraska offer insights to help inform nutrient changes following cover crops.
New study sheds light on previously-unknown hormone pathway, possibly paving the way to the development of crop varieties that use nitrogen more efficiently.
In 2016, test results could be skewed due to when the drought occurred this summer, and may have to be interpreted with some caution, says Michigan State University Extension.
Although a cold front has made it easier to get across wet fields, the University of Tennessee says it's still early for the first nitrogen application in a late winter/early spring split-nitrogen application approach.
