Figure 1. For a 4-foot irrigated band within an 8-foot row spacing, the area that receives fertigation is half of the total, or "real estate," area. Thus, the actual band area of the farm equals 50% of the farm area. However, all IFAS-recommended fertilizer rates are given on a "real estate" acre basis. The amount of fertilizer to apply is calculated based on the entire area of the blueberry farm, regardless of the width of the band to which the fertilizer is applied.
