1. Can Soil Health Metrics Improve Standard Soil Fertility Recommendations?It is commonly speculated that integrating soil health (SH) testing with soil fertility (SF) testing would improve fertilizer recommendation decisions. However, quantified impacts of SH properties, specifically soil biological properties, on fertilizer demand have not been well established. The objective of this research was to explore corn (Zea mays L.) yield response to phosphorus (P) and potassium (K) fertilization as influenced by established SF analysis and common SH metrics....

2. Advancing Precision Nitrogen Management in Agriculture: a Multifaceted ApproachAdvancing precision nitrogen management in agriculture involves achieving a balance between maximizing crop yield and minimizing environmental impact. Traditional nitrogen management approaches often lead to inefficiencies, contributing to environmental issues such as nitrous oxide emissions and nitrogen runoff. Significant challenges persist in quantifying factors influencing nitrogen dynamics in the soil-plant-atmosphere system, including landscape positions, soil properties, weather patterns,... W.
