Phosphorus cycling exerts significant influence upon soil fertility and productivity - processes largely controlled by microbial activity. We adopted phenotypic and metagenomic approaches to investigate phosphatase genes within soils. Microbial communities in bare fallowed soil showed a marked capacity to utilise phytate for growth compared with arable or grassland soil communities. Bare fallow...

The paper provides data on the fl oristic composition of vegetation in anthropogenic habitats suitable for Erigeron × huelsenii, a spontaneous hybrid between the alien E. canadensis and native E. acris s. str. The study is based on 21 phytosociological relevés (vegetation plots) of 5×5 m size made in 2013–2014 in the Polish part of the Lithuanian Lakeland (north-eastern Poland) using the Braun-...

The levels of 16 polycyclic aromatic hydrocarbons (PAHs) were investigated in 27 upper layer (0-25 cm) soil samples collected from the Dagang Oilfield (China) in April 2013 to estimate their distribution, possible sources, and potential risks posed. The total concentrations of PAHs (∑PAHs) varied between 103.6 µg·kg(-1) and 5872 µg·kg(-1), with a mean concentration of 919.8 µg·kg(-1); increased...

We investigated whether the proportion of remotely sensed arable fields increased along a tsetse eradication gradient in the Sebungwe region. We also investigated whether and to what extent this increase in arable fields affected the distribution of the African elephant (Loxodonta africana) between the 1980s and 1990s. Results showed a relatively higher increase in the proportion of arable fiel...

There is currently a significant focus on oil organic carbon, as interest in mitigating climate change by increasing soil carbon stocks leading to efforts include this within farming and the trade of CO2 certificates. In addition, controls many other functions, such productivity. However, results from long-term field experiments suggest that an ever-increasing content soil, at some point, will ...
