Exploring variations in potential carbon and nitrogen mineralization in managed grasslands among the diversity of soils in North Carolina

open access: yesGrassland Research, EarlyView.
Under steady–state conditions, potential nitrogen mineralization in soil under grasslands is closely tied to potential carbon mineralization. This study provides supporting evidence that field–specific nitrogen fertilizer recommendations could be indicated by using a simple and rapid analysis of soil–test biological activity.

An Unfolding Story: AlphaFold's View on Protein Flexibility

open access: yesHelvetica Chimica Acta, EarlyView.
AlphaFold confidence measures allow for detailed proteome‐wide characterization of protein flexibility. All flexibility measures increased substantially in the evolutionary transition from prokaryota to eukaryota. ABSTRACT The AlphaFold confidence measures are related to conformation distribution of the protein.

Legumes

open access: yes, 2017
Legumes are plants whose fruit is a pod. Most of these plants have bacteria on their roots which fix atmospheric nitrogen, which means nitrogen fertilizers are not necessary for their cultivation. In addition, choosing to add legumes in a cropping system improves soil fertility and reduces fertilizer inputs including on the following crops.
