Understanding soil microbial communities in agroecosystems has the potential to contribute to the improvement of agricultural productivity and sustainability. Effects of conversion from long-term wheat plantation to Jerusalem artichoke (JA) plantation on soil fungal communities were determined by amplicon sequencing of total fungal ITS regions. Quantitative PCR and PCR-denaturing gradient gel e...

Many models of phosphorus (P) transfer at the catchment scale rely on input from generic databases including, amongst others, soil and land use maps. Spatially detailed geochemical data sets have the potential to improve the accuracy of the input parameters of catchment-scale nutrient transfer models. Furthermore, they enable the assessment of the utility of available, generic spatial data sets...

The bioavailability of phosphorus (P) in sediments from West Lake and Lake Tai (China) and Lough Erne (Northern Ireland) was evaluated using total P (TP), water soluble P (WSP), readily desorbable P (RDP), algal available P (AAP) and Olsen-P. The results indicated that the TP content, the amounts of phosphorus extracted by each method and their proportions to TP varied widely between sediments ...

It has long been recognized that swabbing methods will not remove all or even a fixed percentage of bacteria from surfaces. Because of this, it is not possible to use these methods for quantitative determinations with any degree of accuracy. Considerable work has been done to develop methods that will permit greater recovery of bacteria from tableware. Higgins (1950) and Cain and Steele (1953) ...

Investigating the dynamics and distribution of soil phosphorus (P) fractions can provide a basis for enhancing P utilization by crops. Four treatments from 29-year long-term experiment in black with maize cropping were involved this study: no fertilizer (CK), inorganic nitrogen potassium (NK), nitrogen, phosphorus, (NPK), NPK plus manure (NPKM). We analyzed different layers using modified Hedle...
