Wolf Trax DDP Nutrients Improve Potato Yield, Quality and Return

The Importance of Micronutrients to Potato Fertilizer

Potatoes have high nutrient requirements. And because they are often planted into coarsely textured soils, potatoes can be prone to micronutrient deficiencies. These deficiencies may reduce plant growth, yield and quality. For example, a lack of boron during the season can reduce tuber size and quality.

Understanding which potato fertilizer sources can provide the nutrition needed – when it’s needed – is important for potato growers.

Potato Fertilizer Field Trials with Wolf Trax DDP Nutrients

In 2014, Holland Agricultural Services conducted fertilizer trials in the central portion of the Columbia Basin, near Othello, Washington. The replicated trial was designed to evaluate the role micronutrients play in potato yield, quality and profitability. It compared three fertilizer treatments:

  1. Grower Standard N-P-K-S with no micronutrients
  2. Grower Standard N-P-K-S with granular zinc sulfate and granular boron
  3. Grower Standard N-P-K-S with Wolf Trax Zinc DDP® and Boron DDP

In general, the fertilizer trial showed that micronutrients can have a big impact on potato yield and quality, and therefore, return per acre.

The above chart shows how both micronutrient treatments increased yield and quality. However, Wolf Trax DDP Nutrients increased the amount of U.S. #1 potatoes by an additional 11 percent compared to granular micronutrients. The Wolf Trax treatment also increased potato size, with the most U.S. #1 potatoes greater than 6 ounces.

At $8.50 cwt potato price, these yield and quality improvements translated to:

  • $224 more gross revenue per acre over the Grower Standard practices
  • $159 more than the granular micronutrients

While this trial focused on zinc and boron, farmers need to select the right micronutrients for their growing conditions. Any combination of Wolf Trax DDP Nutrients can be coated onto dry fertilizer. To see the full line-up of Wolf Trax products, click here.
