Optimal Grazing Exclusion Duration to Enhance Soil Carbon Sequestration in Degraded Grasslands

open access: yesAdvanced Science, EarlyView.
Across China, grazing exclusion reaches the national mean soil organic carbon recovery benchmark sooner in high‐MAP regions (> 500 mm), but recovery is much slower where MAP < 300 mm. Scaling this strategy to 70% of China's degraded grasslands would sequester about 1.52 Pg of soil carbon over 10 years—roughly 17% of annual global fossil‐fuel emissions.

Differences in soil biological activity by terrain types at the sub-field scale in central Iowa US.

open access: yesPLoS ONE, 2017
Soil microbial communities are structured by biogeochemical processes that occur at many different spatial scales, which makes soil sampling difficult.

Assessment of tillage systems in organic farming: influence of soil structure on microbial biomass. First results [PDF]

open access: yes, 2007
Soil tillage modifies environmental conditions of soil microorganisms and their ability to release nitrogen. We compare the influence of reduced tillage (RT) and mouldboard ploughing (MP) on the soil microbial functioning in organic farming.

Microbial biomass carbon and microbial activities of soils receiving chemical fertilizers and organic amendments

open access: yesArchives of Agronomy and Soil Science, 2004
Effect of chemical fertilizers and organic amendments on soil chemical and microbiological properties were studied in soils receiving these amendments over a period of 3 years under tropical conditions. Soil organic C and total N increased in treatments receiving a combination of organic amendments and different doses of chemical fertilizers compared ...

Systematic Engineering of Proteases in Saccharopolyspora Spinosa Reveals Synergistic Enhancement of Spinosad Biosynthesis via Substrate Flux Optimization

open access: yesAdvanced Science, EarlyView.
ARTP mutagenesis yielded Saccharopolyspora spinosa mutant D184 with improved extracellular nitrogen utilization. An integrated workflow of protease genetic manipulation, multi‐omics, and rational synergy design pinpointed a pepP‐clpP‐htpX synergistic triangular combination.

Short-term nitrous oxide emissions from pasture soil as influenced by urea level and soil nitrate [PDF]

open access: yes, 2004
Nitrogen excreted by cattle during grazing is a significant source of atmospheric nitrous oxide (N2O). The regulation of N2O emissions is not well understood, but may vary with urine composition and soil conditions.

Sustainable Phosphorylated Cellulose Nanocrystals: A Dual‐Affinity Platform for High‐Efficiency Enrichment of Intact Glycopeptides and Phosphopeptides

open access: yesAdvanced Science, EarlyView.
AAA ABSTRACT Protein glycosylation and phosphorylation are critical post‐translational modifications (PTMs) governing nearly all cellular functions, yet their analysis remains challenging due to reliance on costly and unsustainable enrichment materials.

Soil microbial biomass carbon and carbon dioxide response by glucose-C addition in black soil of China

open access: yesSoil & Environment, 2019
The soil microbial biomass, atmospheric carbon dioxide and abundance of decomposer are influenced by rate and addition pattern of glucose carbon. The present study was conducted to evaluate the effect of single and repeated additions of glucose-C on ...
