The Level of Luvisols Biochemical Activity in Midfield Shelterbelt and Winter Triticale (xTriticosecale Wittm. ex A. Camus) Cultivation
Jaskulska, Renata
This study aimed to evaluate the usage of Luvisols under the midfield shelterbelt and in the cultivation of winter triticale, together with the influence of physicochemical properties on enzymatic activity. Soil samples were collected in spring, summer, and autumn from the depth of 0–15 cm along the following measurement transect: midfield shelterbelt (S), the border between the shelterbelt and the triticale field (B), cultivated field at a distance of 50 m from point B (F₅₀), and cultivated field at a distance of 100 m from point B (F₁₀₀). The activities of dehydrogenase (DHA), acid phosphatase (PAC), and alkaline phosphatase (PAL) were determined, and a water retention curve (pF) was established. The pH, soil organic carbon (SOC) content, and total nitrogen (Nₜₒₜₐₗ) were also measured. The analysis of the activity results for DHA, PAC, and PAL showed that the triticale soil had a higher level of enzyme activity than the midfield shelterbelt soil during the entire growing season. The soil under the triticale cultivation was slightly acidic, and the shelterbelt soil was very acidic. It was observed that the timing of soil sampling had an impact on the activity of the studied enzymes. The highest levels of DHA, PAC, and PAL activity were found in summer. The midfield shelterbelt demonstrated greater water retention than the winter triticale. The SOC content and Nₜₒₜₐₗ were higher in the shelterbelt than in the winter triticale field.
