Abstract

Soil microorganisms and their activities are considered as important factors in the monitoring and evaluation of soil pollution. In this study, the changes in the microbial properties of the soil such as microbial biomass carbon (Cmic), soil respiration (TS), urease (UA) and β-glycosidase (β-GA) activities of Zn applied at increasing doses to a loam textured soil were evaluated. The experiment was established according to the randomized blocks experimental design with three replications and doses of 0, 75, 150, 300, 600 and 1200 mg kg-1 Zn. To determine the changes in soil microbiological properties, soil samples were taken from each plot every month throughout the year. According to the results of the study; Cmic of soil decreased at higher Zn doses compared to control treatment. On the other hand, TS decreased at low Zn doses and increased at higher doses compared to control. All doses of zinc applied to the soil appear to have negative effects on β-GA. Urease activity was negatively affected by medium and high doses of Zn.

Özet

Toprak mikroorganizmaları ve bunların aktiviteleri toprak kirliliğinin izlenmesi ve değerlendirilmesinde önemli ayraçlar olarak değerlendirilmektedir. Bu çalışmada, tın bünyeli bir toprağa artan dozlarda uygulanan çinko (Zn)’nun toprağın mikrobiyal biyomas karbon (Cmic), toprak solunumu (TS), üreaz (UA) ve β-glikosidaz (β-GA) aktiviteleri gibi mikrobiyal özelliklerindeki değişimler değerlendirilmiştir. Deneme tesadüf blokları deneme desenine göre üç tekerrürlü ve 0, 75, 150, 300, 600 ve 1200 mg kg-1 Zn dozları olarak kurulmuştur. Toprak mikrobiyolojik özelliklerindeki değişiklikleri belirlemek için her parselden yıl boyunca her ay toprak örneklemesi yapılmıştır. Çalışmanın sonuçlarına göre; toprağın Cmic’i kontrol uygulamasına kıyasla yüksek Zn dozlarında düşmüştür. Buna karşın, TS kontrole göre düşük Zn dozlarında düşerken yüksek dozlarda artış göstermiştir. Toprağa uygulanan tüm çinko dozlarının β-GA üzerinde olumsuz etkilere sahip olduğu görülmektedir. Üreaz aktivitesi ise orta ve yüksek dozlardaki Zn’den olumsuz etkilenmiştir.
