Nitrogen (N) Nutrient Map - Sample
Interpretation
Nitrogen (N) is one of the most essential macronutrients for crop development. It plays a critical role in chlorophyll synthesis, protein formation, and overall plant vigor and yield potential.
This map displays nitrogen levels in crop tissues, helping detect imbalances that can affect vegetative growth and productivity.
📊 Nitrogen Levels & Interpretation
The numbers shown in this table may change depending on the type of crop analyzed and its consequently stage.
| Level | Range (% in dry matter) | Interpretation |
|---|---|---|
| Critical | < 2.7% | Severe deficiency. Leads to stunted growth, pale leaves, and significant yield loss. Urgent correction needed. |
| Low | 2.7 – 3.13% | Below optimum. Plants may appear healthy but are underperforming, especially in biomass and grain formation. |
| Medium | 3.13 – 3.56% | Balanced nutrition. Supports healthy vegetative growth and reproductive transition. Suitable for most crops. |
| High | 3.57 – 4% | Sufficient to slightly elevated. Promotes strong canopy but should be monitored to avoid excess vegetative growth at the expense of fruit or grain. |
| Over-sufficiency | > 4% | Excess nitrogen. May delay maturity, increase susceptibility to diseases, promote loss of fruit and cause nutrient imbalances (e.g., low potassium or calcium uptake). |
| Irregular Material | — | Crops in this area exhibit heterogeneous nutrient profiles and biomass, indicating great variability in field conditions. Further analysis is recommended to better understand these differences. |
ℹ️ Tip: Nitrogen is highly mobile in the plant and responsive to management. Adjust fertilization based on crop stage, biomass development, and prior N applications.
🌾 Why Use Nitrogen Crop Maps?
Identify hidden N deficiencies early
Support decisions on fertilizer timing and dosing
Balance canopy development vs. reproductive efficiency
Integrate with water and satellite data to track nutrient use efficiency
