Maize productivity in Central Sulawesi is low, so researchers studied phosphorus fertilizer recommendations for maize crops in different soil nutrient levels. They conducted surveys, tests, and determined P availability classes. The optimal P fertilizer dosages were found to be 76 kg P2O5/ha for low nutrient status, 41 kg P2O5/ha for medium status, and no P fertilizer needed for high to very high nutrient status. This approach can help farmers use fertilizers more efficiently and sustainably, reducing negative impacts on the environment.
