Upcoming Potato Fertilizer Webinar on MicronutrientsBy Wolf Trax
Join a FREE Spudman webinar, “Understanding the Right Micronutrient Tools for Potatoes” on Wednesday, Dec. 7 at noon MT. Potatoes have high nutrient requirements. And because they are often planted into coarsely textured soils, potatoes are often prone to micronutrient deficiencies. Micronutrient 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 sources can provide the nutrition needed – when it’s needed – is important for potato growers. Register here to join the webinar.
Potato Fertilizer Field Trials with Wolf Trax DDP Nutrients
The upcoming Spudman webinar will cover results from independent, third-party field trials. Here is a summary of one fertilizer trial conducted by Holland Agricultural Services in the central portion of the Columbia Basin, near Othello, Washington, in 2014.
The replicated trial was designed to evaluate the role micronutrients play in potato yield, quality and profitability, and compared three fertilizer treatments:
- Grower Standard N-P-K-S with no micronutrients
- Grower Standard N-P-K-S with granular zinc sulfate and granular boron
- 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.
These yield and quality improvements translated to $224 more gross revenue per acre over the Grower Standard practices and $159 more than the granular micronutrients (at $8.50 cwt potato price).

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.
