    Abstract : The effects of sheep trampling on a pastured surface soil have been measured in relation to depth to the water table in the range 0-50 cm. Changes in the bulk density and penetration resistance of the top 0-6 cm of soil and changes in the volumetric water retention at 100 cm suction (available water holding capacity) have been determined. Provided the depth to the water table was 40 cm or more, trampling compacted the soil and increased its bearing capacity. This was accompanied by an increased water retention capcity of the compacted 0-6 cm layer. A water table level of 40 cm is recommended as an acceptable drainage criterion for this soil.
