Abstract
The disadvantages of using utilization quotient (biomass per unit amount of nutrient present in biomass) in comparing nutrient utilization efficiencies of different varieties and species are discussed. A modified approach to the estimation of utilization efficiency is presented. A comparison of efficiencies of two plants calculated by this method gives an index which is the ratio of biomass ratio: tissue nutrient concentration ratio. Theoretical validity and advantages in practical application of this approach are discussed.Keywords
