Afforestation Effect with Conifer and Hard Wood Species on some Physical and Chemical Soil Characteristics

Abstract

In long periods, afforestations have great effects on the physical and chemical soil characteristics. Preserving nutritions elements density of the soil in a balanced quantity in afforestated areas in order to consider the constant development principle is necessary and considerable negative changes shouldn’t take place in soil characteristics. This research compares the pure Pinus teada and blended local conifer afforestations on some soil characteristics in Azbarm Siyahkal area. Soil sample taking method was random-systematic and12 blended samples from hardwood afforestation and 12 blended samples also from conifer afforestations were prepared from the depth of 0 to 30 cm and were transferred to the laboratory to determine the physical and chemical parameters (including: soil tissue, special apparent and superficial mass, pH, electrical conductivity, soil saturation humidity percentage, nitrogen, phosphor, potassium. calcium). The results showed that the amount of humidity saturation percentage, Carbon ratio to nitrogen and phospher among pinus teada species, A Ace in nsig gne e and
