Long‐Term Active Rather than Passive Restoration Promotes Soil Organic Carbon Accumulation by Alleviating Microbial Nitrogen Limitation in an Extremely Degraded Alpine Grassland

Advanced Science, EarlyView.
Active restoration increases soil organic carbon stocks by reducing microbial nitrogen limitation. Nitrogen availability promotes particulate to mineral‐associated organic carbon conversion by reducing microbial carbon use efficiency. Passive restoration has no effect on soil organic carbon stocks.

Total Nitrogen in Fertilizers

Journal of AOAC INTERNATIONAL, 1968
Abstract A three-laboratory collaborative study was made of the comprehensive nitrogen method and the new Raney catalyst powder method for total nitrogen in fertilizers. Both methods worked quite well and, with minor modifications, they should provide the basis for a broader collaborative stvidy to provide an official method for total ...

Soybean Auxin Transporter PIN3 Regulates Nitrate Acquisition to Improve Nitrogen Use and Seed Traits

Advanced Science, EarlyView.
Xu et al. discovers that switching off auxin transporters in soybean, PIN3a and PIN3b, disrupts auxin flow; this triggers ARF‐STF3/4 signal cascade to activate the nitrate importer NPF2.13 and soil nitrogen acquisition. Multi‐year field trials show edited soybeans maintain yield with higher oil content, offering a potential genetic route to improve ...

Design of Single‐Atom Catalysts Anchored in N‐Doped Biphenylene Using Symbolic Regression for Electrocatalytic Nitrate Reduction to Ammonia

Advanced Science, EarlyView.
A high‐throughput in silico calculations for NO3RR based on transition metal doped and nitrogen decorated biphenylene network are performed. A symbolic regression is designed to capture the hidden descriptors of NO3RR for hyper dimensional system entailing large geometric variability.
