Geotechnologies and Soil Mapping for Delimitation of Management Zones as an Approach to Precision Viticulture

Figure 9

Management zones defined by integration of ten variables (granulometry and nutrients). 1: moderate CSS and low CN; 2: low CSS and moderate CN; 3: moderate CSS and moderate CN; 4: moderate CSS and high CN. CSS = content of clay + silt + fine sand; CN = content of nutrients.
