1. Crop Potassium Uptake and UtilizationCropping systems currently face dual challenges of maximizing yields in a sustainable approach. The importance of a balanced nutrition is critical for increasing crop production. In the past decades, comprehensive studies were performed for nitrogen (N) in corn and for phosphorus (P) in soybean. From a physiological standpoint, a synthesis-analysis on potassium (K) content, utilization, interaction with other nutrients and final impact on yield is relevant and needed for properly understanding scientific... |
2. Individual Leaf Selection to Best Represent Whole-plant Nutrient Status in Modern Corn Cropping SystemsIn modern corn cropping systems, fertilization is often required to maintain plant health. Tissue sampling is commonly utilized to evaluate plant nutrient status and determine fertilizer treatment needs. Recommendations exist on which partition/leaf to select for accurate representation of the whole-plant. Recommendations change with growth stage, suggesting to sample the whole-plant at early-vegetative stages, the top-collared leaf at late-vegetative stages, and the ear-leaf during reproductive... B.
