Book (stand-alone)BulletinSoil survey interpretation and its use 1967
Also available in:
No results found.This soils bulletin brings together some of the methods which have been developed and tested in countries that have active programs of making and using soil surveys, and a summary of some of the principles of soil survey interpretation. It is mainly addressed for the soil scientist who is making and interpreting a soil survey, or who is re-interpreting a soil survey already completed. Methods are suggested, with examples, for comparative ratings of soils, capability grouping of soils for the com mon crops, estimating yields of crops on different kinds of soil under defined sets of other growth factors, groupings of soils for range and for woodland management, and use of soil maps and reports in engineering work that involves soils as foundations or as construction material. There are also brief discussions of soil maps for planning, use of soil maps in appraisal of land, and the preparation and use of general soil maps. -
