He oversaw the growth of soil survey interpretations for farming and non-farming works by using, initiated an internationally renowned soil geomorphology research system, and directed the development of a completely new soil classification method, released in 1975 as Soil Taxonomy: A Fundamental Technique of Soil Classification for Building and Interpreting Soil Surveys.

Reconnaissance soil surveys give information and facts for in depth soil surveys and wide land use setting up and agricultural growth. (iii) Specific-Reconnaissance Soil Survey: It is actually a combination of reconnaissance and specific soil surveys which is undertaken for comprehending distribution การสํารวจชั้นดิน of simple soil lessons of collection as well as their phases. (iv) Semi-Comprehensive Soil Survey: This sort of soil survey comprises incredibly detailed analyze of some chosen strips chopping throughout a lot of aerial-Photograph-interpretation (API) units for creating correlation between API units and soils. This sort of soil survey supplies satisfactory information about a variety of styles of soils, which includes problematic soils. Not too long ago There are 2 other types of soil survey have already been recognised i.e. exploratory and speedy reconnaissance soil survey. These cause the preparation of compact scale soil maps that happen to be essential for macro stage preparing for diversified agro-based advancement programmes. Soil Mapping Unit: The distribution of different soil series over the landscape is usually intricate and necessitates some simplification for mapping. This can be achieved by the use of a mapping device, which can be the smallest location of a map that may be delineated by only one boundary at the size utilised. In large scale maps, basic mapping models (narrowly outlined soil series) are delineated to achieve a purity of 80 for each cent or even more in that unit. But การสํารวจดินแดน given that the map scale decreases (from one: 25,000 to one: fifty,000. or one: one,00,000), sophisticated mapping units are used. Procedures used in Soil Survey:
