Abstract

This study evaluated the effectiveness of chiseling and elemental sulfur fertilization upon soil moisture and vegetation response on an upland and a swale site with fine loamy, carbonatic, thermic, typic calcixeroll soils in the Ait Rbaa Perimeter of Central Morocco. Ponding infiltration, soil water content on a mass basis of the 0‐to 10‐cm and 10‐ to 20‐cm soil layers, peak season biomass production, and botanical composition were monitored during the two growing seasons following the treatments (1984/85 and 1985/86). Chiseling significantly (p < .001) improved infiltration on both sites, although the improvement was greater on the finer and less stony swale site. The land treatment also increased the average water content of the top 20 cm of soil. In the chiseled treatments, average soil water content decreased with soil depth on the upland site, while it increased on the swale site...
