Abstract
Carbon (C), oxygen (O), and hydrogen (H), taken up in the form of carbon dioxide (CO2) and water (H2O), are the most important nutrients for tree fruit growth and development, representing more than 95 percent of the tree dry matter. The rest of the nutrients represent the other five percent, and their uptake occurs mainly through the roots, between bloom and the rapid vegetative growth phase. In most perennial tree fruit, initial spring growth and early fruit development rely on reserves accumulated the previous season. Thus, fall nutrient management strategies have had positive effects on building those reserves in apples and cherries. However, the effectiveness of fall sprays will depend on the overall tree health, deficiency level, and demand. This publication presents some considerations to decide whether fall sprays are needed.
