Abstract
The soybean-wheat succession in subtropical and tropical regions has proven to be a viable strategy for improving soil physical, chemical, and biological properties. Among soil management practices, the method of phosphorus (P) application can significantly influence grain yield (GY) and production costs. This study aimed to evaluate the effects of broadcast and banded P applications on soil chemical attributes, GY, yield components, and nutrient export in a soybean-wheat succession system. The experiment was arranged in a randomized block design with a 2 × 4 factorial scheme, consisting of two P application methods (broadcast and banded) and four P rates (0, 26, 52, and 87 kg ha−1), with four replicates. Two consecutive crop cycles were assessed. Soil chemical properties were influenced following the soybean cycle, with notable changes in organic carbon (OC) and P available, while after wheat, significant effects were observed on OC, P, Al3+, H+Al (potential acidity), and cation exchange capacity (CEC). In soil under no-till management with adequate available P levels, increasing P rates enhanced GY only in soybean. No significant differences were observed between broadcast and banded P application in the soybean-wheat succession cultivated in a Typical Oxisol. However, the highest P rate (87 kg ha−1) resulted in greater N, P, and K concentrations in soybean grains and increased N and Zn concentrations in wheat grains. Additionally, the Mehlich-1 and ion exchange resin extractants effectively predicted GY in soybean.
