The study evaluated phosphorus (P) fertilization strategies for the soybean/wheat rotation over three growing seasons (2021/2022 to 2024/2025) in a highly clayey Dystrophic Oxisol. The goal was to determine the most efficient P2O5 rates that maximize yield while maintaining the soil nutrient balance.
