, Sorptivity, the most important variable affecting management of early infiltration processes, is significantly influenced by the initial water content (in addition to several other soil properties). 20 to 1500 kPa. In general, decreased soil water pressure resulted in increased sorptivity down to -100 KPa, while further decreases in soil water pressure affected sorptivity adversely. Measuring and Scaling Dynamic Soil Properties in Soil Survey
, Map-unit design includes decisions about the types of map units (consociations, associations, or complexes) used as well as the arrangement and composition of those map units. The individual map-unit components have their own scales-how finely are taxonomic classes defined, or how many different slope classes should be recognized. In the NCSS, soil property information is then attributed to map-unit components using available data and expert knowledge. Decisions about the inclusion of data (is it part of the central concept?) and rules-of-thumb about appropriate property classes impact the values (low-representative value (rv)-high) populated in available databases such as SSURGO. Currently, the NCSS uses the Soil Change Guide to organize the collection of use-dependent properties under the name Dynamic Soil Properties (DSPs)
