The 106 Soil Units form 26 Soil Groups. The FAO soil map was a very simple classification system with units very broad, but was the first truly international system, and most soils could be accommodated on the basis of their field descriptions. The FAO soil map was intended for mapping soils at a continental scale but not at local scale.
The field guide and the horizon and layer symbols are newly added to the WRB Manual and are meant to replace the FAO Guidelines for Soil Description (2006) for the use with WRB. Annex 4 is a soil description sheet. It is a separate document in the form of an excel file to fill in the surveyed field characteristics.

FAO stated that Land suitability is the fitness of a given type of land for a defined use. The land may be considered in its present condition or after improvements. The process of land suitability classification is the appraisal and grouping of specific areas of land in terms of their suitability for defined uses.
Statistics are at the core of the work of the Food and Agriculture Organization of the United Nations (FAO), its mandate and strategic goals. Article I of its Constitution states that “The Organization shall collect, analyse, interpret and disseminate information relating to nutrition, food and agriculture.
The Unified Soil Classification System (USCS) is a soil classification system used in engineering and geology to describe the texture and grain size of a soil. The classification system can be applied to most unconsolidated materials, and is represented by a two-letter symbol. Each letter is described below (with the exception of Pt):
ISRIC is a regular member of the ISC World Data System, and is known as WDC-Soils since 1989. [4] ISRIC's main open access databases include WoSIS, [ 5 ] a large database of quality-assessed and standardised soil profile data for the world, that has been used for producing soil property maps at 250 m resolution, with quantified uncertainty,for ...
Soil texture triangle showing the USDA classification system based on grain size. For soil resources, experience has shown that a natural system approach to classification, i.e. grouping soils by their intrinsic property (soil morphology), behaviour, or genesis, results in classes that can be interpreted for many diverse uses.
