Abstract

Predictions of 30-year average moisture deficits (MD 30) were carried out by means of kriging and co-kriging in a stratified survey area. Major soil map delineations, as distinguished by a soil survey, showed different internal variability. Stratification resulted in an increase of precision of predictions on strata with low MD 30 variability and a decrease in strata with high MD 30 variability. Use of co-kriging resulted in an average increase of precision of MD 30-maps of about 10%. This study illustrates use of available soil survey information for stratifying a survey area to enhance precision of predictions. -Authors
