Abstract
Mixed plantations of nitrogen fixing trees is one method of improving soil fertility after successive harvests of fast growing trees. Soil properties were studied in 7- year old pure and mixed plantations of Populus deltoides Marsh. and Alnus subcordata C.A.Mey near Chamestan in north of Iran(Caspian region). Total nitrogen was higher in 15-30 cm soil layer under pure Alnus subcordata forest as compared with a mixture of 67% Populus: 33% Alnus ar 50% Populus: 50% Alnus or 33% Populus: 67% Alnus or 50% Populus: 50% Alnus. However, soil pH, EC, organic matter, available P, K, Ca, and Mg were statistically the same in these pure and mixed plantations. Finally, we can conclude that the use of mixed plantation of A. subcordata as a nitrogen fixing tree with P. deltoides on soil physico- chemical properties up to 7 years of age.
