Investigation of soil chemical properties of Ramsar Bineshki forests in the altitude range of 400 to 1700 meters

Awareness of the condition of soils in forest areas and the study of the effects of various activities on soil properties is very important and effective in forest management. Soil properties change under the influence of various environmental factors such as altitude. The aim of this study was to investigate soil indices at altitudes of 400 to 1700 meters above sea level in a series of Benshaki forest area in Ramsar city in Mazandaran province.

For sampling soil variables in each altitude floor, 3 sample plots of 400 square meters at intervals of 100 meters from each other were identified.

Soil samples were taken from 0-10 and 10-30 cm depths. Soil properties measured include sand content, clay content, nitrogen content, potassium content, carbon and organic matter content and soil pH.

The result of this study showed that the effect of altitude on soil characteristics (percentage of sand, percentage of clay, percentage of nitrogen, potassium, percentage of carbon and organic matter and soil pH) is significant in different altitude classes (P ˂).
