Özet:

 This study examines the relationship between catalase activity in degraded soils and soil properties, and addresses its potential as an indicator of soil health and productivity. Catalase, a key enzyme reflecting microbial activity and soil aeration, has been analyzed in 30 soil samples collected from the disturbed surface layer 0-15 cm depth of erosion-prone areas characterized by rubble accumulation on hill slopes and soil compaction in foot slopes. The soil in the study area is classified as Typic Xerortent. Catalase enzyme activity in the soil samples varied between 10.4 and 48 µl O2 g-1 dry soil. In addition to catalase, the physicochemical properties of the soil were also assessed, including pH, electrical conductivity, organic matter content, and texture. Nutrient contents, including nitrogen 0.046-0.239 g N 100 g-1, phosphorus 1.77-20.05 µg P g-1, and potassium 0.01-3.31 meq K 100 g-1, were also measured. A positive correlation was observed between catalase activity and potassium and phosphorus levels, but the relationship with nitrogen was statistically insignificant. These findings suggest that catalase activity can serve as a biological indicator for the early detection of degradation in soils at risk of erosion. The study provides valuable insights into the impact of erosion on soil biochemistry and highlights the role of catalase in assessing soil health and guiding sustainable land management practices.

 Bu çalışma, degrade topraklardaki katalaz aktivitesi ile toprak özellikleri arasındaki ilişkiyi incelemekte ve toprak sağlığı ve verimliliğinin bir göstergesi olarak potansiyelini ele almaktadır. Mikrobiyal aktiviteyi ve toprak havalanmasını yansıtan anahtar bir enzim olan katalaz, toprak sıkışması ile karakterize edilen ayak yamaçlarındaki ve tepe yamaçlarında moloz birikimi ile karakterize edilen erozyona hassas alanların bozulmuş yüzey tabakasından 0-15 cm derinlik toplanan 30 toprak örneğinde analiz edilmiştir. Çalışma alanındaki toprak Tipik Xerortent olarak sınıflandırılmıştır. Toprak örneklerinde katalaz enzim aktivitesi 10.4 ile 48 µl O2 g-1 kuru toprak arasında değişiklik göstermiş. Katalazın yanı sıra toprak fizikokimyasal özellikleri de değerlendirilmiştir; bunlar pH, elektriksel iletkenlik ve organik madde içeriği gibi özelliklerdir. Azot 0.046-0.239 g N 100 g-1, fosfor 1.77-20.05 µg P g-1 ve potasyum 0.01-3.31 meq K 100 g-1 da dahil olmak üzere besin içerikleri de ölçülmüştür. Katalaz aktivitesi ile potasyum ve fosfor seviyeleri arasında pozitif bir korelasyon gözlemlenmiştir, ancak azot ile ilişki istatistiksel olarak anlamsızdır. Bu bulgular, katalaz aktivitesinin erozyon riski taşıyan topraklarda bozulmanın erken tespiti için bir biyolojik gösterge olarak hizmet edebileceğini öne sürmektedir. Çalışma, erozyonun toprak biyokimyası üzerindeki etkisine dair değerli bilgiler sağlamakta ve katalazın toprak sağlığını değerlendirme ve sürdürülebilir arazi yönetimi uygulamalarını yönlendirmedeki rolünü vurgulamaktadır.
