We used potassium hydroxide (KOH) to induce rapid soil pH changes and then observed microbial community change over 48 hours in anaerobic conditions before measuring denitrification enzyme activity (DEA). Soil pH was elevated from 4.7 to 6.7, 8.3 or 8.8, straddling...

The ongoing evolution of tracer mixing models has resulted in a confusing array of software tools that differ in terms of data inputs, model assumptions, and associated analytic products. Here we introduce MixSIAR, an inclusive, rich, and flexible Bayesian tracer...

Exogenous calcium is able to maintain photosynthesis level under low night temperature (LNT) stress. Nevertheless, the mechanism for supplementary calcium to mitigate photosynthesis barriers under LNT has not been as clear as expected so far. This study mainly...

Semi-selective enrichment, followed by PCR screening, resulted in the successful direct isolation of fast-growing Rhizobia from a dryland agricultural soil. Over 50% of these isolates belong to the genus Neorhizobium, as concluded from partial rpoB and near-complete...

Background: Glomalin-related soil protein (GRSP) and soil organic carbon (SOC) contribute to the formation and stability of soil aggregates, but the mechanism by which global atmospheric nitrogen (N) deposition changes soil aggregate stability when it alters the...

Most cropland in the U.S. is characterized by large monocultures, whose productivity is maintained through a strong reliance on costly tillage, external fertilizers, and pesticides ( Schipanski et al., 2016 ) . Despite this, farmers have developed a regenerative...
