🌽 Potassium (K) Nutrient Map - Sample
Reproductive Stage Interpretation
Potassium is a key macronutrient that plays a critical role in water regulation, enzyme activation, sugar transport, and stress resistance in crops. Its availability is essential throughout the growing cycle, particularly during reproductive stages to support grain or fruit filling.
This map shows the distribution of potassium levels (%) in crop tissue, allowing for targeted interpretation and action.
📊 Potassium Levels & Interpretation
| Level | Range (%) | Interpretation |
|---|---|---|
| Critical | < 1.7% | Severe deficiency. May lead to poor water balance, weak stalks, marginal leaf burn, and reduced yield. Requires immediate correction. |
| Low | 1.7 – 2.1% | Suboptimal for high-demand stages. Crops may underperform under stress or during grain fill. Fertilization should be considered. |
| Medium | 2.11 – 2.4% | Balanced level for most crops. Supports normal growth and efficient nutrient/water use. |
| High | 2.41 – 2.655% | Well-nourished condition. No need for additional potassium at this stage. |
| Over-sufficiency | > 2.65% | Excess levels may lead to antagonism with magnesium (Mg) and calcium (Ca), potentially causing secondary deficiencies. Monitor balance. |
| Irregular Material | — | Unreliable data. Likely caused by sampling artifacts or extreme localized variability. Reassessment may be needed. |
