🌽 Zinc (Zn) Nutrient Map - Sample
Reproductive Stage Interpretation
Zinc (Zn) is a vital micronutrient required in small amounts, but its impact on plant growth and yield is significant. It is essential for enzyme activity, protein synthesis, and hormone regulation (especially auxins), which are crucial for root development and grain formation.
This map highlights the spatial distribution of zinc availability across your field, guiding strategic interventions where deficiency might limit yield potential.
📊 Zinc Levels & Interpretation
| Level | Range (mg/kg) | Interpretation |
|---|---|---|
| Critical | < 15 mg/kg | Severe deficiency. Likely to cause stunted growth, leaf discoloration (especially interveinal chlorosis), and poor flowering or fruit set. Immediate correction needed. |
| Low | 15 – 43 mg/kg | Suboptimal. Early signs of deficiency may occur under high demand or stress. Supplemental Zn may be beneficial, particularly in corn, wheat, and legumes. |
| Medium | 44 – 72 mg/kg | Adequate levels. Supports healthy plant development and yield. Regular monitoring advised under intensive cropping systems. |
| High | 73 – 100 mg/kg | Optimal to high. Generally beneficial, though unnecessary supplementation should be avoided. |
| Toxic | > 100 mg/kg | Risk of toxicity. May interfere with phosphorus uptake and root function. Evaluate soil balance and application rates. |
| Irregular or Minimal Surface Material | — | Areas where soil or biomass conditions may have compromised sample quality. These zones require visual validation or resampling. |

💡 Tip: Zinc deficiency is common in high pH (alkaline) soils, especially in calcareous regions. Zinc maps are particularly important for crops like corn, sorghum, citrus, and legumes, which are more sensitive to its availability.
