Abstract

Soil colloids play a critical role in controlling chemical behavior, particularly in tropical sub-optimal drylands dominated by variable-charge soils. However, information on the comparative effects of organic and inorganic amendments on soil charge characteristics across different soil orders remains limited. This study aimed to evaluate the effects of compost, biochar, CaCO₃, and SP-36 on the charge characteristics of tropical dryland soils. Nine amendment combinations were applied to topsoil (0–20 cm) from Andisols (Saree), Inceptisols (Cucum), and Ultisols (Jantho), followed by incubation for 60 days at 25–27 °C under field capacity conditions. Soil charge parameters were analyzed before and after incubation. Results showed that amendment type and rate significantly affected soil charge characteristics, with responses varying among soil orders. Organic amendments (15–30 t ha⁻¹) and SP-36 (2–4 t ha⁻¹) decreased pH₀ and significantly increased cation exchange capacity (CEC) and net negative charge, indicating improved soil reactivity. In contrast, CaCO₃ increased pH₀ and reduced negative charge. These findings support the strategic use of organic amendments to enhance soil fertility and sustainability.
