Do the Soil's Physiochemical Properties Fluctuate with Season and Soil Depth in the Ecological Critical Areas (ECA) of Sundarbans, Bangladesh?

Soil physiochemical properties in the Ecological Critical Areas (ECA) of the Sundarbans, Bangladesh, exhibit significant seasonal and depth-related fluctuations. Key parameters such as bulk density (1.05–1.18 g/cm³), pH (7.30–8.54), electrical conductivity (1.05–2.13 ms/cm), and nutrient levels (N: 0.5–0.72 mg/g, P: 0.03–0.06 mg/g, K: 10.5–12.88 mg/g, Na: 16.89–20.53 mg/g) vary across seasons and soil layers, with stock values for available nutrients ranging from 52.5 to 84.96 kg/ha (N), 3.15 to 7.08 kg/ha (P), 1.10 to 1.52 t/ha (K), and 1.77 to 2.42 t/ha (Na). These findings highlight the dynamic nature of ECA soils, critical for aquaculture productivity and dike greening initiatives. The study, conducted in Satkhira district during pre- and post-monsoon seasons, provides actionable insights for sustainable land management in this threatened region.
