This CNC video features Federico Teixeira, Technical Director of the Agroglobal demonstration fields, explaining leaf sap analysis as a tool for in-season nutrient monitoring in silage maize.
Key Points
- Location: Silage maize plot at Agroglobal’s demonstration fields (Portugal).
- Purpose: Collect leaf samples for analysis to guide supplementary fertilisation decisions in the coming weeks.
- Sampling Method:
- Collect before 9 AM.
- Take the 3rd-oldest and 3rd-newest leaves from multiple maize plants.
- Cut a 10 cm section from the middle of each leaf.
- Package samples (separately for old/new leaves) with minimal air (not vacuum-sealed).
- Send via fast courier to the lab.
- Results: Available in 2 business days.
- Current Status: Second round of sampling; first round revealed micronutrient deficiencies.
- Application: Informed partnering fertiliser companies for targeted adjustments, complementing the initial soil analysis-based fertilisation plan.
- Benefits: Fine-tune nutrition with small doses for optimal vegetative growth, quality, and productivity.
This demonstrates practical use of leaf analysis for precise, data-driven adjustments in maize, aligning with NUTRI-CHECK NET’s focus on improving nutrient efficiency.
