Abstract

This study was carried out to determine the changes in soil urease enzyme activity and the relationship between its and some properties of soil as a result of application of organic wastes to soils having different pH. The experiment was conducted as a pot experiment under controlled conditions in a greenhouse and 3 repeats with soils having 3 different pH (acid, neutral, alkaline) values. As organic materials; tobacco processing waste (TW), rice husk compost (RHC) and municipal solid waste (MW) were used in four different rates (0.0, 2.5, 5.0 and 7.5%). After a one-month incubation period, the plant was grown in the prepared pots. At the end of the experiment, urease enzyme activity was determined in soil samples taken from pots and the highest enzyme activity was determined in acid soil with 5.0% TW application, in neutral soil with 7.5% MW application and in alkaline soil with 7.5%TW application. Moreover, statistically significant relationships were found between soil urease enzyme activity and soil pH, EC, soil organic matter, and lime content.

Özet

Bu çalışma organik atıkların farklı pH değerlerindeki topraklara uygulanması sonucunda topraktaki üreaz enzim aktivitesindeki değişimleri ve üreaz enzim aktivitesi ile toprağın bazı özellikleri arasındaki ilişkileri belirlemek amacıyla yapılmıştır. Deneme serada kontrollü koşullarda saksıda ve üç farklı pH (asit, nötr, alkali) değerine sahip toprakta üç tekerrürlü olarak yürütülmüştür. Organik düzenleyici olarak kullanılan tütün işleme atığı (TA), çeltik kavuzu kompostu (ÇEK) ve çöp kompostu (ÇK); %0.0, %2.5, %5.0 ve %7.5 şeklinde 4 doz olarak uygulanmıştır. Bir aylık inkübasyon döneminden sonra hazırlanan saksılarda bitki yetiştirilmiştir. Deneme sonrasında saksılardan alınan toprak örneklerinde üreaz enzim aktivitesi belirlenmiş ve asit pH’ya sahip toprakta en yüksek enzim aktivitesi %5.0 TA uygulaması sonrasında, nötr pH’ya sahip toprakta %7.5 ÇK uygulaması sonrasında, alkali pH’ya sahip toprakta ise %7.5 TA uygulaması sonrasında belirlenmiştir. Ayrıca deneme sonrasında topraktaki üreaz enzim aktivitesi ile toprağın pH, EC, organik madde ve kireç içerikleri ile istatistiksel açıdan önemli ilişkiler belirlenmiştir.
