Abstract
Mississippi’s agriculture faces challenges from high rainfall, bedded cropping systems, and varying soil testing methods. Many producers apply phosphorus (P), potassium (K), and sulfur (S) in the fall to reduce spring workload and rain-related delays. While fall fertilization raises concerns about yield losses, research indicates minimal differences in soybean (Glycine max L.) yield between fall and spring applications. Raised beds also limit cover crop (CC) establishment despite their potential benefits. We explored strategies to integrate CCs into bedded systems while assessing bed stability and residue management during soybean production. Additionally, Mississippi’s use of two soil nutrient extraction methods highlights the need for correlation and calibration. Our studies aim to refine fertility management, optimize CC use, and improve soil test interpretation to enhance soybean production in the region.
