Abstract

Fruits and vegetables are valuable and should be managed with fine-scale precision agriculture to counteract spatial variations.
Equipment and operation dynamic response is modeled by time-delayed differential equations.
Transportation delay and time constant should be small relative to management zone transit time to minimize average errors.
Issues related to time-shift compensation and pulse-width-modulation to improve accuracy are discussed.
