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

Table 4

Results of ANOVA as a factor of soil classes. LS = Levene statistic; = significance of homogeneity of variances test, %; = significance of statistic, % (ANOVA). Number of samples for the classes of soils and total: CXve1, CXve2, CXve3, PBAcal1, PBAcal2, PBAcal3, RRh1, RRh2, RRh3, and RRh4 and total equal to 8, 10, 22, 6, 15, 7, 11, 4, 8, 17, and 108, respectively.
