In simple terms: Drought effects on wet soils in inland wetlands and peatlands

Abstract: Soils associated with wet and ephemerally wet environments, i.e. wet soils, cover an area greater than 12.1 million km2; inland wetlands deliver at least Int$27.0 trillion in tangible and intangible benefits. However, due to their intimate association with wet environments, wet soils are at risk of degradation during drought events. This review investigates the …

In simple terms: Earth microbial co-occurrence network reveals interconnection pattern across microbiomes

Abstract: Background: Microbial interactions shape the structure and function of microbial communities; microbial co-occurrence networks in specific environments have been widely developed to explore these complex systems, but their interconnection pattern across microbiomes in various environments at the global scale remains unexplored. Here, we have inferred an Earth microbial co-occurrence network from a communal catalog …

Soil colour – visual health and chemistry

Soil colour conveys a wealth of information. Not only are soil colours a key diagnostic feature of horizonation (and therefore classification) but they can also tell you about soil organic matter, clay mineralogy, salt and carbonate accumulations, and drainage conditions. Most people know that dark brown or black soils are good for growing plants. Why? …

In simple terms: The effect of fire affected Pinus radiata litter and char addition on soil nitrogen cycling

Abstract: In pine forest litters, decomposition rate is directly affected by the pathway the needle followed to the ground, whether that was via programmed apoptosis and abscission or via stress induced loss through branch damage or tree death. Stress induced losses may occur due to fire damage, which leads to a post-fire litter layer composed …

In simple terms: Post fire litters are richer in water soluble carbon and lead to increased microbial activity

Abstract: Under conditions of increased fire season length and area affected by fire, stocks of carbon stored in forests are at increased risk of burning. While much research has investigated the immediate loss of above ground and below ground carbon stocks through combustion during a fire, there has been little research on subsequent organic matter …
