HS1197: How to Calculate Fertigation Injection Rates for Commercial Blueberry Production

Figure 1. For a 4-foot irrigated bed within an 8-foot row spacing, the area that receives fertigation is half of the total, or "real estate," area. Thus the actual bed area of the farm equals 50% of the farm area. However, all UF/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 bed to which the fertilizer is applied.
