Survival and growth of Nothofagus pumilio seedlings under several microenvironments after variable retention harvesting in southern Patagonian forests

Table 1 Nested ANOVAs and means for treatments (AR = aggregated retention, DR = dispersed retention, RT = under the influence area of remnant overstorey trees, D = under woody debris, R = over secondary roads) for the volumetric soil water content (VSW) (percent), crown and debris cover (CC) (percent), global radiation (GR) (watts per square meter), soil acidity (pH), cation exchange capacity (CEC) (milliequivalents per 100 g), soil bulk density (SD) (grams per cubic centimeter), and nutrient soil content of organic carbon (C) (milligrams per cubic centimeter), total nitrogen (N) (milligrams per cubic centimeter), phosphorous (P) (milligrams per cubic centimeter), potassium (K) (milligrams per cubic centimeter), and magnesium (Mg) (milligrams per cubic centimeter)
