The aim of this study was to systematically evaluate the effect of different seasons on dynamical of nutrients and the correlation between them in peat soil as a basic for water management plan. This study examines nutrient dynamics in peat soil facilitated by effective water management planning, focusing on a case study in Perigi, South Sumatra, Indonesia. Employing a combination of field observations and laboratory analyses, the research identifies key nutrient fluctuations in various hydrological conditions. The different sample in each season (wet and dry) was carried out based on the fluctuation of water table between 20cm-80cm to identified the dynamics of nutrients. Results showed the positive correlation between pH and others nutrients which are indicate the influence of ion H+ to enhance bond with other chemicals. The significant result of each nutrient between wet and dry seasons showed that increased rainfall can cause leaching of nutrients like nitrogen, phosphorus, and potassium. It will lead to optimize water management significantly enhances nutrient availability and soil fertility, leading to improved agricultural outcomes. The findings emphasize the importance of sustainable water practices in peatland areas to promote ecological health and agricultural productivity, providing valuable insights for policymakers and land managers.
