Description The impact of grazing on physical properties of Vertisol was studied from 1996 to
2000 in the Ethiopian highlands. The study was conducted at two sites with 0-4 %
and 4-8 % slopes at Tero Jemjem watershed in Ginchi, 80 km west of Addis
Ababa. The main objective of this work was to study effect of livestock on soil
microorganisms of the cracking and self-mulching Vertisol. The stocking rate was
moderate grazing 1.8 animal-unit months per hectare (AUM) ha-1, heavy grazing
3.0 animal-unit months per hectare (AUM) ha-1 (3.0 AUM) ha-1 and a control
treatment with no grazing. Soil bacterial content was high in medium grazed
treatments at 0-4% slope in alls sampling seasons. In contrast the soil fungal
content was high in non-grazed plots. Soil nitrifying bacteria was high in clipping
treatments as compared to the rest of the treatments. The soil fungal quantity
differed significantly with sampling seasons; highly significant correlation
coefficient was observed between soil fungal quantities and sampling seasons.
There was also highly significant correlation between soil fungal and soil bacteria
quantity.
