Urine contains about 50 % of the phosphorus (P) and about 90 % of the nitrogen (N) excreted by humans and is therefore an interesting substrate for nutrient recovery. Source-separated urine can be used to precipitate struvite or, through a newly developed technology, nitrified urine fertilizer (NUF). In this study, we prepared (33)P radioisotope- and stable (15)N isotope-labeled synthetic NUF (...

Viola calcarata L. and dubyana Burnat ex Gremli belong to the V. complex in section Melanium (Violaceae family). For first time, essential oils (EOS) obtained by hydrodistillation from dried flowers, were analyzed GC/MS SPME-GC/MS describe their volatile chemical profile. Differences qualitative quantitative composition between two violets have been found. A total of 43 compounds identified amo...

Biochar has many potential benefits in agroecosystems such as increasing productivity of crops and modifying soil nutrient content. is sourced from waste materials which could easily sustainably remedy current challenges concentrated agricultural operations that use manure-based fertilizers. However, relatively little known about its effects on forage species conjunction with manure or biochar ...

negatively affected by disturbance. meadow barley (Hordeum brachyantherum Nevski) (Hickman 1993). Purple needlegrass, blue wildrye, bluegrass and California melic are droughttolerant species that typically occupy well-drained upland sites. In contrast, creeping wildrye and meadow barley are less drought-tolerant and typically grow in the moist soils of seeps, streams and wetland margins (Walker...

Phytoremediation uses plants and their associated microorganisms in conjunction with agronomic techniques to remove or degrade environmental contaminants. The objective of the field study was to evaluate the effect of vegetation establishment plus fertilizer addition on the biodegradation of alkylated polycyclic aromatic hydrocarbons in a crude oil-contaminated soil. Four replications of the fo...
