We aimed to determine the relationship between biochar properties and colonisation of roots by arbuscular mycorrhizal (AM) fungi in agricultural soil. We used a range of biochars that differed in pH,

This intensifies the thawing for ice and snow, leading to a low/lack snow pack and more rainfall, and resulting in more overland flow, can significantly aggravated soil erosion 2,7. Serious erosion.

The relationships considered were plant taxonomy: soil microbial taxonomy, and plant traits: soil microbial traits. For each experimental treatment combination, we separately assessed whether the.

Even though soil biota play a key role in maintaining the functioning of ecosystems, the vast majority of existing studies focus on aboveground organisms. Many questions about the fate of belowground.

Culture-independent molecular surveys of plant root microbiomes indicate that soil type generally has a stronger influence on microbial communities than host phylogeny. However, these studies have.

We aimed to reveal the seasonal variation of the fungal communities in agriculture systems. We also hypothesized that the stochastic process played a role in the seasonal variation of soil fungal.

We test the common assumption that organic carbon (OC) storage occurs on sand-sized soil particles only after the OC storage capacity on silt- and clay-sized particles is saturated. Soil samples from.
