Within grazed pastures, urine patches are hot spots of nitrogen turnover, since dietary N surpluses are excreted mainly as urea in the urine. This short-term experiment investigated 13C uptake in microbial lipids after simulated deposition of cattle urine at 10.0 and 17.1 g of urea C m(-2). Confined field plots without or with cattle urine amendment were sampled after 4 and 14 days, and soil fr...

Estuarine sediments are the repository for a wide range of contaminants. Anthropogenic impacts and variations in the belowground biomass of salt marsh plants potentially select for different sediment microbial communities with different functional capabilities, including the ability to biotransform anthropogenic contaminants. There are large differences in both root morphology and the amount of...

Understanding the change in function of biological community under different soil conditions is key to effective quality monitoring and mitigation degradation. Current measures suffer from drawbacks with most techniques having high expense, low throughput or a narrow focus on one component community. The aim this study was assess use volatilomics as method profile microbial compare technique ph...

The Sahel is an ecologically vulnerable region where increasing populations with a concurrent increase in agricultural intensity has degraded soils. Agroforestry offers approach to remediate these landscapes. A largely unrecognized agroforestry resource the are native shrubs, Piliostigma reticulatum , and Guiera senegalensis that varying degrees already coexist row crops. These shrubs improve s...

The cost effectiveness of using exogenous phosphorus to remediate heavy metals in soil, which would alter the structure soil microbial community, had been widely acknowledged. In present study, phospholipid fatty acid (PLFA) technology was taken as breakthrough point, and rhizosphere microorganisms different growth stages (jointing stage maturity stage) Minghui 86 (MH) Yangdao No.6 (YD) rice we...
