Tree‐to‐Tree Nutrient Variability in Pecan Orchards

Abstract

Tree‐to‐tree uniformity is desirable for nutrient management in orchards, particularly with the prevalence of nutrient application via fertigation, which makes it very difficult to tailor nutrient distribution for individual trees. The goals of this study were to measure the degree of variability of foliar nutrient concentrations exhibited by pecan trees in an Arizona orchard as well as to determine the importance of different sources of variation.
