5.🍀 LCI – Leaf Chlorophyll Index

Purpose:

• Detect nutrient stress early

• Measure variations in nitrogen uptake

• Support precision fertilization strategies

Observations:

• High LCI values = strong chlorophyll levels, healthy nutrient uptake 🌿

• Low LCI values = possible nutrient deficiencies, often nitrogen-related

Recommendations:

• Apply targeted fertilization in low LCI zones.

• Use LCI insights to guide nitrogen application rates for optimal crop performance.

• Combine with NDRE for a complete view of crop nutrient status.

LCI Color Indices Explained:

🟥 Red / Orange (Very Low LCI):

• Severe nutrient deficiency, especially nitrogen.

• Immediate corrective fertilization required.

🟨 Yellow (Low LCI):

• Early nutrient stress, reduced chlorophyll.

• Monitor closely and consider supplemental feeding.

🟩 Light Green (Moderate LCI):

• Adequate but not optimal nutrient uptake.

• Fine-tune fertilization strategy.

🌿 Dark Green (High LCI):

• Strong chlorophyll activity and healthy nitrogen levels.

• Crops are thriving under current practices.
