4. When to Apply Fertilizer?

Timing is everything in potato farming. Explore the optimal periods for fertilizing your crop, considering different growth stages and avoiding the risks of over-fertilization.

The timing for fertilizing potatoes falls into three key stages:

Pre-planting (1-2 weeks before planting):

  • This is the main fertilization stage. Apply a balanced all-purpose slow-release fertilizer or well-aged compost (1-2 pounds per 10 square feet) to the planting bed and mix it well into the soil. This provides a base of nutrients for the early growth of the potato plants.
  • Consider adjusting the soil pH to a slightly acidic range (6.0-6.5) if necessary, as potatoes prefer this for optimal nutrient uptake.

Side-dressing (6-8 weeks after planting):

  • When the potato plants are about 6 inches tall, you can provide an additional boost of nitrogen to support leaf growth and canopy development. Use a nitrogen-rich fertilizer, like ammonium nitrate, and apply it in a band along the sides of the rows, keeping it away from the stems to avoid burning.
  • Alternatively, you can side-dress with compost tea or diluted fish emulsion.

Maintenance (optional):

  • In nutrient-deficient soils, further side-dressing every 3-4 weeks with a balanced fertilizer or organic matter may be beneficial. However, stop fertilizing at least 4-6 weeks before harvest to allow the tubers to mature and prevent excess nitrogen from affecting their storage quality.

Additional factors to consider:

  • Variety: Early and maincrop potatoes might have slightly different timing needs. Early varieties mature faster, so adjust the side-dressing timing accordingly.
  • Weather: Avoid fertilizing during heavy rain or windy conditions, as nutrients can be washed away.
  • Soil test results: If you have conducted a soil test, adjust your fertilization plan based on the specific nutrient needs of your soil.

5. Application Methods

Discover various methods of applying fertilizer, including topdressing, side-dressing, and soil incorporation, each tailored to different stages of potato growth.
