A multivariate approach to plant mineral nutrition: dose–response relationships and nutrient dominance in factorial experiments
Canonical variates analysis was used to compare the effects of fertilization on the concentrations of five mineral elements (N, P, K, Ca, and Mg) in young shoot tissues of six tundra plant species of three different growth forms. There were two specific objectives: (i) to determine whether it was po...
