	  abstract     = {Most agricultural crops cultivated in Brazil are highly
nutrient demanding. Brazilian soils are generally acidic with low base
saturation and available nutrients. Demand for fertilizer application
has increased because the national agricultural sector expansion. To
improve productivity without environmental impact, there is the need
for the utilization of novel procedures and techniques to optimize
fertilizer application. This includes the digital soil mapping and GIS
application applied to mapping in different scales. This paper is
based on research, realized during 2005 to 2010 by Brazilian
Corporation for Agricultural Research (EMBRAPA) and its partners.
The purpose was to map soil fertility in national and regional scales.
A soil profile data set in national scale (1:5,000,000) was constructed
from the soil archives of Embrapa Soils, Rio de Janeiro and in the
regional scale (1:250,000) from COMIGO Cooperative soil data set,
Rio Verde, Brazil. The mapping was doing using ArcGIS 9.1 tools
from ESRI.},
