Abstract
Methods of application and compositions of foliar fertilizers are specifically chosen to address crop nutritive demands varying with growth stage. Two separately timed applications of foliar fertilizers are described. One corresponds to a bud emergence or seedling germination stage of plant development and the other corresponds to a reproductive or fruiting period of the crop's life cycle. Concentrations of required nutrients are related to the amount removed in crop production. Leaf surface penetration enhancers are added to each foliar fertilizer to increase nutrient uptake by the plants.
