We studied total stored carbon—aboveground and underground—in Larrea divaricata and L. cuneifolia species, which are the dominant species and form extensive shrublands in both extensive geomorphological units in Mendoza: piedmont and lowlands (45,022 km2). In randomly distributed plots...
Long-term interactions between vegetation succession and soil quality in alfalfa fields were investigated in the semi-arid Loess Plateau of China. The successional ecosystem is composed of six different planting-year alfalfa fields (namely, 3–5–9–15–21–25 years). The yield, cover, and height of...
The emphasis on integrated use of organic amendments and fertilizers has made it imperative to study the effect of crop residues and organic manures on urea hydrolysis, which governs the release of N from urea fertilizer. Urea hydrolysis in soils is an enzymatic decomposition process facilitated...
Field experiments were conducted to test the influence of two types of anionic polyacrylamide (PAM) on soil erosion and runoff of sloping land in Jordan under natural rainfall conditions. The two PAMs used in this study, Superfloc A-836 and Superfloc A-870, varied widely in molecular weight...
The legume Dalbergia sissoo Roxb is an important forest tree of the arid and semi-arid regions. The efficiency of Bradyrhizobium (Ds Rhz-9) and Glomus fasciculatum (Thaxter sensu Gerd.) Gerd. and Trappe to promote growth of D. sissoo and the effect of indole acetic acid (IAA) on the tripartite...
Woody species have a discontinuous influence on their immediate vicinity and beyond. Most sampling methods record mean values over the area being sampled, not accounting for information at the scale of pattern created by individual woody plants. This article outlines development and testing of a...
