396 Nutrients Spatial and Temporal Variability Management

Oral Session
S04 Soil Fertility & Plant Nutrition High spatial nutrient variability exists in many fields due to natural causes or management practices. Also, climate and management practices may introduce high temporal variability for some nutrients. Information will be presented focusing on traditional and precision agriculture diagnostic tools and practices that can be used to assess nutrient variability better and improve nutrient management.
