Florida commercial horticultural production: Constraints limiting water and nutrient use efficiency

Abstract

Application of water and nutrients for horticultural production in Florida can be accomplished through many different methods. Often, the irrigation system that is used determines the potential use efficiency for both water and nutrients. Producers face many constraints, real and perceived, that affect management decisions. This article provides an overview of many of the constraints that are encountered and identifies those management practices that are most effective for overcoming these constraints with respect to commonly used irrigation systems. These constraints include those related to irrigation system design and capabilities, soil factors, cultural practices, management intensity, and economic and regulatory conditions. Ultimately, the goal of this discussion is to determine where future research efforts should be focused and what critical issues may be on the horizon that may affect the Florida horticultural industry.
