Effect of coppice forest clearance on soil moisture, temperature and certain selected soil characteristics

Öz:
The main goal of this study was to assess the effect of coppice forest removal on soil moisture and temperature (e.g., maximum, minimum and mean daily temperatures) along with some selected soil properties. The study was conducted in the Belgrad Forest in Istanbul. A coppice forest plot was selected in the forestland. Half of the plot was cleared as a treatment site while other half was left as a control plot. The plots were 100 m by 100 m in size. Soil moisture and temperature values were recorded at hourly intervals at 1 m and 50 cm soil depths, respectively. Soil samples in disturbed and undisturbed areas were collected at 0–5 cm soil depth and analyzed for saturation capacity (SC), hydraulic conductivity (HC), bulk density (BD), particle density (PD), total porosity (TP), sand silt and clay contents, electrical conductivity (EC), pH, loss on ignition (LOI), and organic matter content (OM). Two-tailed paired student t-test were used to compare means at an alpha level of 0.05. Results revealed that daily soil moisture significantly increased from 32% to 37%, daily temperature from 14.5oC to 15.9oC, daily maximum temperature from 14.6oC to 16.2oC, and daily minimum temperature 14.4oC to 15.7oC following coppice forest clearance. Clearcutting of woody vegetation did not affect the soil sand, silt and clay contents, HD, PD, pH, and EC values in the soil; however, it caused a significant increase from 1.3 g/cm3 to 1.5 g/cm3 in the BD and decreases from 6% to 3% in the OM content, from 17% to 8% in the LOI, from 52% to 46% in the TP, from 51 cm/min to 32 cm/min in the HC, and from 33% to 24% in the SC of the soil.

Baltalık ormanında traşlama kesiminin toprak nem, sıcaklığı ve belirli bazı toprak özellikleri üzerindeki etkisi

Öz:
Bu çalışmanın amacı, baltalık olarak işletilen bir ormanda traşlama kesimin toprak nemi, sıcaklığı ve bazı toprak özellikleri üzerindeki etkisinin araştırılmasıdır. Araştırma İstanbul'da Belgrad Ormanı'nda gerçekleştirilmiştir. Bu amaçla, traşlama kesimin yapıldığı meşe-gürgen baltalık ormanından bir deneme parseli ile traşlama kesilmiş alanın bitişiğindeki kesilmemiş alandan ise kontrol amaçlı bir parsel alınmıştır. Her iki alanda 0-5 cm toprak derinliğinden bozulmuş ve bozulmamış toprak örnekleri alınmış ve örneklerin permeabilite (HC), tekstür, pH, elektriki iletkenlik (EC), organik madde (OM) içeriği, ateşte kayıp (LOI), hacim ağırlığı (BD), tane yoğunluğu (PD), maksimum su tutma kapasitesi (SC) ve toplam boşluk hacmi (TP) analiz edilmiştir. Veriler çift taraflı eşlenikli t-testi kullanılarak α=0,05 seviyesinde değerlendirilmiştir. Araştırma sonuçları, baltalık ormanının traşlama kesilmesinin, günlük ortalama toprak neminin %32'den %37'ye, günlük ortalama toprak sıcaklığının 14,5oC'den 15,9oC'ye, ortalama günlük maksimum toprak sıcaklığının 14,6oC'den 16,2oC'ye, ortalama günlük minimum toprak sıcaklığının 14,4oC'den 15,7oC'ye ve BD değerlerinin 1,3 gr cm3'ten 1,5 gr/cm3'e yükselmesine; buna karşılık toprakların OM içeriğinin %6'dan %3'e, LOI değerlerinin %17'den %8'e TP değerlerinin %52’den %46’ya, HC’nin 51 cm/dak’dan 32 cm/dak’ya ve SC’nin %33’ten %24’e düşmesine yol açtığını göstermiştir. Buna karşılık, sonuçlar baltalık ormanında tıraşlama kesiminin toprakların tesktürü, PD, pH ve EC değerleri üzerinde önemli bir etkisinin olmadığını göstermiştir.
