I’ve seen a number of petioles this year on potatoes with sky high nitrate levels. In this situation I like to look at a couple key indicator nutrients used in Nitrogen conversion S, Cu, Fe, Mn, Mo, Zn Manganese in this scenario could be addressed... (trending down 2wks in a row). Mn, is a major driver in enzymatic activities of nitrogen assimilation, photosynthesis and chlorophyll production.
