Saturated [K s ], field saturated [K fs ] and unsaturated [K(ψ)] SUMMARY There is increasing interest in the landspreading of slurries, sludges, effluents and fertilisers, resulting from the need to recycle increasing volumes of waste from high production agriculture units, old and new sewage treatment works and industrial facilities. Wastes should be spread only on suitable unsaturated soils a...

The objective of this study was to investigate the effect of two N-fertilizer rates and plant density on herb yield and active substance of feverfew (Tanacetum parthenium Cv.Zardband). The experiment was performed in a factorial trial, RCB design. Three rates of N-fertilizer (0.75 and 150 kg/ha) and plant densities of 10 and 20 cm were applied as treatments, with three replications. After perfo...

A four site monitoring network was established in the Missouri portion of Metropolitan St. Louis during 2008 to characterize spatiotemporal patterns in PM10 arsenic. Arsenic measured at two urban sites in the City of St. Louis was typically higher than arsenic at two suburban sites. Spatiotemporal variability in arsenic is examined by plotting the Pearson correlation coefficient (PCC) against t...
