Effects of early fertilization on the performance of Nothofagus dombeyi planted in the Coastal Range of south-central Chile

Native Nothofagus dombeyi growth rates excel in secondary forests and in some plantations, and the species has good timber quality. However, few have reported on the effects of fertilization on N. dombeyi plantations. This is a key matter since fertilization has environmental and financial costs, an...
