Nutrients Plants Require for Growth University of Idaho

Potassium is mobile in plants (table 2). Potassium deficiencies can be diagnosed by looking at the older plant tissue. Deficiencies appear along the outer margins of older leaves as streaks or spots of yellow (mild deficiencies) or brown (severe deficien cies). Potassium plays several roles in plants.

Interaction between MicroNutrient and Primary Nutrient ...

Iron plays an antagonistic role in relation to zinc in the rice plant and in waterlogged rice soils. The ferrous (Fe2+) iron can compete with zinc (Zn2+) in the uptake process for the formation of chelates or other reactions. Manganese interferes with the translocation of Fe from the roots to shoots.
