Describing Surface Soil Properties Their Seasonal Changes and Implications for Management 1

  1. R. B. Grossman and
  2. F. B. Pringle2


A number of aspects of field and field office documentation that pertain particularly to cultivated soils are discussed. These include position laterally in the tillage-determined configuration, ground surface cover, soil roughness, definition of sub-zones of the tillage zone, kinds and measurement of cracks, soil consistence, water state classes, infiltration rate, bulk density, and aggregate stability. A record is described for use-dependent temporal agronomic information. The record is specific to a soil survey area, provides a vehicle for locally knowledgeable people to assign values, and joins together the use and time invariant information from soil survey documentation with use-dependent temporal quantities.
