Macroaggregate disintegration mediates forest gap impacts on MAOC decrease in karst ecosystems

Geoderma
Forest gap disturbances, which are projected to intensify with climate change, threaten the stability of mineral-associated organic carbon (MAOC) in karst soils.

Hotspots of soil organic carbon storage revealed by laboratory hyperspectral imaging [PDF]

, 2018
Subsoil organic carbon (OC) is generally lower in content and more heterogeneous than topsoil OC, rendering it difficult to detect significant differences in subsoil OC storage. We tested the application of laboratory hyperspectral imaging with a variety

Biomarkers evidence shows a preferential occlusion of microbial necromass in mineral-associated and not particle organic matter

Geoderma
Increasing experimental evidence and modeling efforts have found that microbial necromass is highly associated with mineral-associated organic matter (MAOM).

Amazon Basin forest pyrogenic carbon stocks: First estimate of deep storage [PDF]

, 2017
Amazon Basin forest soils contain considerable soil organic carbon stocks; however, the contribution of soil pyrogenic carbon (PyC) to the total is unknown.

Severe nutrient depletion reshapes rhizosphere microbial succession toward necromass recycling under continuous monocropping of Coix lacryma-jobi

Crop Design
Continuous monocropping often leads to progressive soil functional degradation and yield decline, yet the mechanisms by which severe nutrient depletion and stoichiometric imbalance reshape microbial functional reorganization in the rhizosphere remain ...

Plants and microorganisms both contribute to soil organic matter formation through mineral interactions: Evidence from a subtropical forest succession

Geoderma
Understanding the formation and stabilization of soil organic carbon (SOC) is essential for predicting SOC dynamics. Traditionally, it was believed that SOC accumulates primarily through the selective retention of recalcitrant plant lignin components ...

Phosphorus nutrition of mycorrhizal trees [PDF]

, 2010
Globally, phosphorus (P) limits productivity of trees in many forests and plantations especially in highly weathered, acidic or calcareous pro!les. Most trees form mycorrhizal associations which are prevalent in the organic and mineral soil horizons ...

Phytase activity in lichens [PDF]

, 2015
Phytase activity was investigated in 13 lichen species using a novel assay method. The work tested the hypothesis that phytase is a component of the suite of surface-bound lichen enzymes that hydrolyse simple organic forms of phosphorus (P) and nitrogen (

Sediment Bacterial Communities in Nutrient Cycling and in the History of the Baltic Sea [PDF]

, 2013
The Baltic Sea has experienced fresh-, brackish, oxic and hypoxic water phases and its deepest bottom areas are naturally hypoxic. Recently, eutrophication has caused spreading of hypoxic areas and internal feedback mechanisms, such as the release of ...
