Thomas and James T. Midcap Horticulture DepartmentPesticide and fertilizer recommendations often are made on a pounds-per-acre or tons-per-acre basis forfield production. However, greenhouse and nursery operators, landscape professionals and orchardists oftenmust convert these recommendations to smaller areas, such as row feet or square feet per tree or per pot. Pints,cups, ounces, tablespoons and teaspoons often are the common units of measure. Metric units of measure canfurther complicate publication is designed to help growers make these calculations and conversions and to provide otherdata useful in the management, planning and operation of horticultural enterprises.
