Abstract

Lebak swamp land presents a promising potential for agricultural development, especially for rice cultivation. However, its utilization faces constraints due to soil acidity and low levels of soil organic matter. This study aims to evaluate the availability and distribution of organic matter content in lebak swamp rice fields in Medasari Village. The research employed a detailed survey method over a 10-hectare area, with one representative soil sample taken per hectare. Laboratory analysis showed that the soil organic matter content ranged from 1.54% to 4.76%, with an average of 2.57%, falling into the low to very low category. The pH of the soil was categorized as very acidic to moderately acidic, ranging from 3.87 to 5.22. The Cation Exchange Capacity (CEC) ranged from 6.66 to 22.5 cmol kg⁻¹, with lower values associated with low organic matter and dominant kaolinite clay minerals. The findings highlight the need for integrated soil management practices, including organic matter addition and liming, to enhance soil fertility and sustain productivity in lebak swamp rice fields.
