This research investigates the influence of two organic amendments, Mango leaf and Bitter leaf, on the potassium content in swampy and clay soils. Potassium plays a crucial role in supporting microbial activity during bioremediation, making it an essential nutrient in hydrocarbon-contaminated environments. The study explores the temporal variation in potassium concentrations in soils treated with powdered Mango leaves, Bitter leaves, yeast, and NPK fertilizer over a period of 84 days. The results show an increase in potassium levels in both swampy and clay soils treated with Mango leaf and Bitter leaf, highlighting the potential of these organic amendments to promote soil nutrient replenishment and support bioremediation processes.
