3.5 Tiny Bytes: Understanding Plant Nutrient Mobility

Awareness of nutrient mobility in plants drastically improves in-field diagnosis of crop issues. In this episode, we dive deep into plant nutrient mobility and how nutrient mobility impacts visual symptoms in the field.
• Discussion on the concept of nutrient mobility 
• Insights into mobile vs. immobile nutrient deficiencies 
• Importance of tissue testing for accurate diagnoses
Relatively immobile nutrients (symptoms will appear on newest leaf tissue): S, Zn, Fe, Cu, B, Ca, Mn, Mo, Ni
Relatively mobile nutrients (symptoms will appear on oldest leaf tissue): N, P, K, Mg
