The influence of soil dynamics on physical-chemical properties of soils from teak and coconut plantations

Öz

This study investigated the influence of soil dynamics on soil physical and chemical properties in teak and coconut plantations. Soil samples were collected from different depths (0-30 cm, 30-60 cm, 60-90 cm, and 90-120 cm) and analyzed for various physical and chemical properties. The results showed significant correlations between organic carbon (2.23-8.43 g/kg), total nitrogen (0.23-0.83 g/kg), electrical conductivity (90.33-110.33 μS/cm), exchangeable acidity (1.73-2.33 cmol/kg), and available phosphorus (0.61-1.42 mg/kg). The study found that the coconut farm soils tend to be more acidic than the teak farm soils, with pH levels ranging from 4.87 to 5.20. The texture of the soils in both farms varies with soil depth, with sand content ranging from 744.1 to 835.0 g/kg and clay content ranging from 112.0 to 242.5 g/kg. The study also found that both farms have relatively high levels of organic carbon and organic matter, which can help to improve soil fertility and structure. The results have significant implications for soil fertility management, soil salinity management, and sustainable agriculture in tropical regions. The study highlights the importance of integrated soil management practices that consider the interactions between different soil properties. Regular soil testing and monitoring are recommended to maintain optimal soil conditions for plant growth.
