Level 4 Data Summaries

Key Findings (Brief)

The result from the study found that soil texture is a major factor that affects soil erosion. Soil erosion from the Mulei was higher than from the other two sites even if the site was only conducted on an intermediate slope. The difference from Mulei and the other sites is the soil texture is fine to very fine sand to sandy loams, that can allow the transport of the soil material.

  • Soil movement ranged from 42.3 to 227 tonnes/ha.
  • Soil texture was important for the amount of soil being moved.
  • There is an increase in the soil texture for sites 1 to 3 ranging from heavy loam to sandy clay loam at site 3.
  • Slope effect is more evident during 1976 / 77 monitoring period. Sites 2 and 6 lost appreciably more soil than their paired lower slope sites 1 and 5.
  • Movement of soil down the slopes was a noticeable feature of both seasons.
  • Early in the season (periods 1 - 2) soil moved from the higher slope positions and deposited in the lower sections, the degree of this depends on the amount and intensity of rainfall.
