Acid sulfate soil isuse asan alternative in optimizing suboptimal land to achieve corn self-sufficiency. Balanced fertilization plays an important role in efforts to improve corn yields. This study aimed to determine the effect of planting methods and optimal dose of fertilization. This research was carried out in potential acid sulfate soils with B type overflow. This study was arranged in factorial Randomized Complete Block Design (RCBD) consist of 2 factors. The first factor was the planting method consistof Zigzag, Legowoand Conventionalplanting methods. The second factor was the fertilizer types comprising NPK phonska 450 kg ha-1+ urea 300 kg ha-1+ SP36 300 kg ha-1, NPK mutiara 450 kg ha-1+ urea 300 kg ha-1+ SP36 300 kg ha-1, Urea 450 kg ha-1+ SP36 300 kg ha-1+ KCl 300kg ha-1, and NPK phonska 300 kg ha-1+ SP36 300 kg ha-1. The results showed that the application of different types of fertilizer and planting methods could improve pH in all treatments from very acidic to acidic. pH, EC, and Ehof acid sulfate soils at 70 and 100 days after planting (dap) were not affected by the interaction between different types of fertilizer and planting methods. Total N content in Zigzagplanting method was significantly lower compared to in Conventionalplanting methods. Meanwhile, available P increased to very high. The Exchangeable K content was only increased in the fertilizer treatment with the addition of KCl reaching a value of 0.42 cmol + kg-1at 30 dap. Zigzagplanting method significantly increased corn yield to 31% higher than in Legowoplanting method and 16% higher than in the Conventionalplanting method. The application of fertilizer with a mixture of KCl significantly increased corn yield to 26.25%. Therefore, the Zigzagplanting method and fertilizer with KClmixture are recommended for corn cultivation in acid sulfate soils.
