The infiltration rate was measured by double ring infiltrometer using the water ponding method. Large clods of bulk samples were broken by hand into smaller segments along natural cleavages prior to air drying. The aggregates were sieved using the wet sieving technique. Soil water stable aggregates were assessed according to methods described by Cambardella and Elliott (1993) and expressed as aggregates N1.0 mm. The remaining soil was ground and sieved through a 2-mm sieve, and 50 g of the sieved soil was used for particle size analysis by the hydrometermethod . Organic carbon content was determined by Walkley and Black method. Total N was measured with the Kjeldhal method and available P by ammonium acetate extraction, colorimetrically. Surface
stoniness, vegetative cover and soil macro fauna were measured using 1m2 quadrate at each sampling site.
