Why Nutrient Availability is Not Determined Only by pH

Most growers are familiar with the chart showing available nutrients according to soil pH. The problem is that the chart is so incomplete it borders on being inaccurate. Nutrient availability is not one dimensional, as the pH diagram makes it appear to be. Additional dimensions include redox and microbial activity.
In this webinar, John will describe nutrient availability from a multi-dimensional chemistry based perspective, and how to develop more accurate perspectives on nutrient delivery.
