Randomized trial examines microbial characteristics in oil palm plantation soil, suggesting improvements in soil quality.

This study aims to assess how decomposed oil palm leaf litter affects soil microbial characteristics.
Soil samples collected from lower, middle, and upper slope positions at 0-15 cm and 15-30 cm depths.
Soil physical and chemical properties, microbial populations, microbial biomass, and enzyme activities were analyzed across sampled areas.
Descriptive statistics and ANOVA were used for data analysis.
Plantation soils exhibited higher organic carbon, phosphorus, exchangeable bases, and microbial biomass compared to control.
Microbial biomass carbon was 196.8 mg/kg and nitrogen was 29.2 mg/kg in the plantation soils.
Enzyme activities such as dehydrogenase, urease, amylase, and lipase were significantly higher in plantation soils.

Akpan et al. (2026) studied this question.
