Potato Nutritional Specifications at Different Stages:

Nutrient requirements and application rates to kilograms (kg) and grams (g) for your potato fertilization program:

1. Nutrient Requirements:

   • Nitrogen (N): Approximately 39 kg/ha (86 lb/A)
   • Phosphorus (P): Approximately 5.4 kg/ha (12 lb/A)
   • Potassium (K): Approximately 43.5 kg/ha (96 lb/A)
   • Calcium (Ca): Approximately 1.36 kg/ha (3.0 lb/A)
   • Magnesium (Mg): Approximately 2.67 kg/ha (5.9 lb/A)
   • Sulfur (S): Approximately 3.98 kg/ha (8.8 lb/A)
   • Zinc (Zn): Approximately 0.32 kg/ha (0.70 lb/A)
   • Manganese (Mn): Approximately 0.01 kg/ha (0.03 lb/A)
   • Iron (Fe): Approximately 0.24 kg/ha (0.53 lb/A)
   • Copper (Cu): Approximately 0.02 kg/ha (0.04 lb/A)
   • Boron (B): Approximately 0.01 kg/ha (0.03 lb/A)

2. Fertilization Practices:

   • Nitrogen (N): Apply 39 g/m² at planting and 39 g/m² during tuber initiation.
   • Phosphorus (P): Apply 5.4 g/m² prior to planting as basal application or sidedress before tuber initiation.
   • Potassium (K): Adjust based on soil test levels and yield goals. On low K testing soils, consider both broadcast and banded applications.

3. Application Rates:

   • For a 100-foot row, apply one kilogram of 10-10-10 fertilizer (or two kilograms of 5-10-10).

Remember to adapt these recommendations to your specific field conditions and crop requirements. If you have any further questions, feel free to ask Hunter! 🌱🥔🌿
