Oregon Consumer Protection

In this Growers Spotlight we interview Don Wolf, a fertilizer specialist for the Oregon Department of Agriculture (ODA).

Don Wolf is widely regarded as an industry leading watchdog for nutrients and beneficial products. His tests to prove or disprove nutrient and pesticide claims have helped growers carefully separate quality products from those that are dishonest or hyped up.

In this Spotlight, Don discusses consumer protections, safety measures, and the plant nutrition industry. We interviewed Don because we wanted to know Oregon’s standards for nutrients, and why they’re testing their nutrients.

The following was an interview with an industry expert. Growers Network does not endorse nor evaluate the claims of our interviewees, nor do they influence our editorial process. We thank our interviewees for their time and effort so we can continue our exclusive Growers Spotlight service.

What are plant nutrients?

In order to be defined as a nutrient, an element must be necessary for the plant in one of two ways:

  1. The element is part of an essential plant metabolite or constituent (IE sugars).
  2. A plant will die or cease growing/reproducing without said element.

Please note that this says nothing about the optimal amount of nutrients for any given plant, just that a plant will cease to grow/reproduce, or die without the nutrient.
