There are growing concerns about the environmental impact of intensive agricultural production including citrus cultivation on our natural resources, i.e., water resources. In addition to enhancing citrus tree growth, fruit yield, and quality of citrus orchards, the properly adopted citrus best management practices (BMPs) should help protecting our environment. Thus, the goals of citrus BMPs are to integrate different approaches to optimize irrigation water and minimize surface- and sub-surface transport of nutrients and pesticides, and control citrus related pests, weeds, and disease attack. This article reviews the major citrus BMPs including: i) citrus irrigation management, ii) citrus nutrient management, and iii) citrus pests, weeds, and disease control. Environmental impact of citrus cultivation on our water resources, if the recommended BMPs are not properly adopted, are also discussed. The information presented in this article should help scientists, professionals, and citrus growers adopt the recommended BMPs for sustainable citrus cultivation.
