Moisture content at high pH value, about 6, is closely corelated to clay content. This procedure circumvents the expensive soil granular analysis of many samples and provides a quick and easy determinant for variations in soil texture. Gravimetric moisture determination under controlled air-dry conditions is relatively cheap (40 working hours for 628 samples) as compared to the external costs of specialized texture analysis (175 Dfl per sample)
