Soil Particle Density Protocol [PDF]
, 2003 The purpose of this resource is to measure the soil particle density of each horizon in a soil profile. Students weigh a sample of dry, sieved soil from a horizon, mix it with distilled water and then boil the mixture to remove any air. The mixture cools

Technical Guidance Sheet (TGS) on normal levels of contaminants in English soils : copper (Cu) : technical guidance sheet supplementary information TGS03s, July 2012 [PDF]
, 2012 Both the NSI (XRFS) and G-BASE data sets are derived from a soil sample that has been aggregated (composited) from a number of subsamples collected over the area of a site, rather than a single point sample.

Data documentation for the bare soil experiment at the University of Arkansas [PDF]
The reflectivities of several controlled moisture test plots were investigated. These test plots were of a similar soil texture which was clay loam and were prepared to give a desired initial soil moisture and density profile. Measurements were conducted

Long-term fate of sewage-sludge derived cadmium in arable soils [PDF]
, 2003 The focus of this work was to improve knowledge of the long-term fate of cadmium supplied to arable soils by sewage sludge. Emphasis was placed on measured and modelled changes in the solubility and mobility of cadmium, resulting from long-term turnover ...

Морфогенетична и химична оценка на почви, третирани с утайка от Софийската пречиствателна станция
Почвознание, агрохимия и екология, 2013 Soils from the South-West of the Kremikovtsi terrain were studied in 2010. A soil profile from an arable land (fallow) treated with 4.2 t/da sludge from the Sofia Waste Water Treatment Plant (WWTP) and another control profile – untreated with sludge ...

Does Wheat Cultivar Choice Affect Crop Quality and Soil Microbial Communities in Cropping Systems? [PDF]
, 2008 Wheat (Triticum aestivum L.) cultivars may have differential effects on soil microbial communities and the breadmaking quality of harvested grain. We compared six Canadian spring wheat cultivars under organic and conventional management systems for yield,

Uncertainty in the determination of soil hydraulic parameters and its influence on the performance of two hydrological models of different complexity [PDF]
, 2009 Data of soil hydraulic properties forms often a limiting factor in unsaturated zone modelling, especially at the larger scales. Investigations for the hydraulic characterization of soils are time-consuming and costly, and the accuracy of the results ...
