Determination the Effects of the Post-Afforestation Elapse on Soil Properties and Nitrogen Mineralization (Giresun-Şebinkarahisar Case)
Kastamonu University Journal of Forestry Faculty
Aim of study: In this study, it is aimed to reveal the effects of time on some soil properties and nitrogen mineralization potential in scotch pine afforestation areas. Material and methods: The study was carried out in the afforestation areas in Şebinkarahisar Forest Management Directorate. Soil samples were taken from two depth levels (0-15 cm and 15-30 cm Soil samples were taken from afforestation areas (afforested 1, 5 and 20 years ago) and adjacent unforested(control) areas. Some physical
... eas. Some physical and chemical analyzes as well as nitrogen mineralization measurements were done in the soil samples. Main results: It was determined that the period after afforestation has a statistically significant effect on the change of soil properties. Thus, while the sand and C / N ratio decreased with afforestation, clay, bulk density and pH increased. The difference in the effect of the time passed over planting times in terms of net mineralization data in nitrogen mineralization was found to be statistically insignificant. Equal incubation conditions prevented the difference in planting time. Highlights: With the study, changes in soil properties have been revealed through afforestation studies in areas that are sensitive to erosion and the necessity of improving potantial erosion sites has emerged.
