Abstract (2. Language): 
The objective of our study was to determine soil urease and B-Glucosidase enzyme activities in soil samples taken from three different depths (0-5 cm, 5-15 cm and 15-30 cm) and under different type of vegetation (apple, pine, clover, wheat and followed land). Highest activities, both urease and B- Glucosidase were determined in soil samples representing parcels planted with clover. Enzyme activity showed increase in parcels which have high level of organic matter and total nitrogen. Urease enzyme activity was found higher than B -Glucosidase activity in all samples. As the soil deepens, significant increase was monitored in urease activity (P<0.01), whereas, decrease was recorded in B-Glucosidase activity. We conclude that urease and B -Glucosidase activities were significantly effected by vegetation types and soil depth.

Abstract (Original Language): 
Farklı vejetasyon uygulaması altındaki toprak örneklerinde (yonca, buğday, elma, çam ve nadas) ve üç farklı derinlikte (0-5, 5-15, 15-30 cm) üreaz ve B-Glikozidaz enzim aktiviteleri araştırılmıştır. Yonca ekili parsellerden alınan toprak örneklerinde her iki enzim aktivitesinde de en yüksek değer saptanmıştır. Toprak organik maddesi ile toplam azotu yüksek olan parsellerde enzim aktiviteleri de artmaktadır. Üreaz aktiviteleri, B- Glikozidaz aktivitelerinden bütün vejetasyon uygulamalarında yüksek bulunmuştur. Toprak derinliği arttıkça üreaz aktivitesinde önemli düzeyde artma (P < 0.01), B-Glikozidaz aktivitesinde ise azalma gözlenmiştir. Farklı derinlikle beraber farklı vejetasyon uygulamalarında üreaz ve B- Glikozidaz aktiviteleri önemli ölçüde etkilenmiştir (P < 0.01).
