Jodi and Sarah explore the crucial distinction between mobile and non-mobile nutrients in soil. Understanding how these nutrients behave not only aids in effective soil sampling but also enhances soil fertility management, providing fertilizer users with the knowledge they need to maximize returns on their fertilizer dollars. 

They cover
• Mobile vs. non-mobile nutrients
• Nutrient behavior based on soil charge 
• Cation exchange capacity (CEC) and nutrient adhesion 
• Sampling strategies for mobile vs. non-mobile nutrients
