Profile Soil Carbon and Nitrogen Dynamics in Typical Chernozem under Long-Term Tillage Use
For the first time in research literature, this report presents the seasonal changes of total organic carbon (TOC), total nitrogen (TN), and TOC:TN ratio in Chernozem solum (0–100 cm) as effected by 14 years of application of conventional tillage (CTu ...

ABSTRACT Landscape planners in semi‐arid and arid regions often plant native shrubs to reduce water and fertilizer use; however, landscape management practices might alter shrub resource use and make them more dependent on irrigation and fertilization. Our objective was to assess whether water and nutrient subsidies in managed landscapes affected plant

Effect of soil health management on soil water storage for climate resilience
Abstract Soil health (SH) management has been promoted to improve climate resilience across agricultural systems. An on‐farm field study was conducted to (1) evaluate the soil water storage (SWS) in SH and conventional (CV) management systems across four paired sites in Minnesota and Wisconsin and (2) to assess the response of these management systems ...

Mollisol Productivity Under Two Management Levels
This article 'Mollisol Productivity Under Two Management Levels' appeared in the International Rice Research Newsletter series, created by the International Rice Research Institute (IRRI). The primary objective of this publication was to expedite communication among scientists concerned with the development of improved technology for rice and for rice ...

Soil, competition, and niche shifts shape the floral mosaic of an annual plant diversity hotspot
Abstract Premise Plant species with affinity for harsh substrates often have well‐defined edaphic (soil) niches and are ideal for exploring questions of community assembly. Vertic clay soils are chemically and physically challenging to plant establishment and productivity, and annual plant communities associated with these soils of the San Joaquin ...

Elevated moisture stimulates carbon loss from mineral soils by releasing protected organic matter
The effect of soil moisture on microbial activity and soil carbon storage remains unclear. Here, via Mollisol incubation experiments, the authors show elevated soil moisture can accelerate total carbon loss by facilitating microbial access to previously ...

Soil physical quality of Mollisols quantified by a global index [PDF]
Indicators synthesizing the state of the structural quality and the function of the porous system are useful for assessing soil production capacity as well as the way it may serve natural ecosystems. This research aimed (i) to determine indicators of the state and function of the porous system, (ii) to use them to derive a global index to characterize ...
