Abstract:
Soil water content under natural, thinned and clearcut stands of ponderosa pine was compared among treatment, depth of measurement, and date of measurement. Comparisons were made for the complete study period, February to September, 1966, and for the growing season, June to September, 1966. Actual soil water content and soil water content expressed as differences from a base date water content, were used in the comparisons. The soil water content at maximum recharge, March 19, 1966, and the first reading date of the growing season0 June 8, 1966, were used as base readings. The study was conducted on White Mountain Apache Tribal lands in cooperation with the U. S. Bureau of Indian Affairs. Study sites were located approximately five miles east of McNary, Arizona. The soil water data was determined using a neutron probe and standard manufacturer's calibration curves. Split-split plot analyses of variance and the Duncan' s New Multiple Range Test were used to statistically analyze the data. It was concluded that the removal or reduction of ponderosa pine stand density produced a significant annual decrease in soil water loss, with the greatest differences occurring during the spring snow melt and soil recharge period. For the summer growing season, precipitation was quickly lost by evaporation and transpiration and there were no significant differences in soil water losses due to the presence or non-presence of the pine stands.
