Abstract (English)Studies were conducted in a semi arid area of Kenya to determine the effects of tillage methods and soil management practices on crust strength and thickness during the 1998/1999 cropping seasons. Conventional and minimum tillage methods, surface mulch, incorporated mulch and goat manure were studied. Crust strength and thickness were measured at sowing, mid season and harvest. The results obtained indicate that there were large seasonal changes in the field measurement of crust strength and thickness over the two seasons. There were significant differences in crust strength and thickness between sampling times within the treatments. There was a good relationship between crust strength and thickness at R2 = 0.46. All the soil management practices and tillage methods resulted into a decrease of crust strength and thickness with time. Minimum tillage however had stronger crusts than conventional tillage at. Crust thickness was significantly influenced by tillage methods and the soil management practices.
