Soil textures. Geological formations (Geo.); Depths of soil (D.) range in cm; Soil management (M.) T = Tillage, G=Green natural cover, GT= alternating of green natural cover and tillage, between the inter-rows. L=Levene test; F=Fisher test; bf=Brown Forsythe test; ns = not significant; * and ** = significant per p≤0.05 and p≤0.01, respectively. Within each column, medium values with different letters are significantly different at SNK test (p<0.05).
