SS-AGR-348: Phosphorus Fertilizer Recommendations for Sugarcane Production on Florida Organic Soils

Figure 3c. Relationships between pre-crop Mehlich 3-extractable P and relative sugar yield for (a) individual zero P plots, (b) mean relative sucrose, and (c) minimum relative sucrose. Zero P relative sugar/acre for individual plots was determined by dividing tons sugar/acre (TSA) of each zero P plot by the corresponding highest TSA for all P rates in that replication. Relative sugar/acre values for (b) and (c) are the mean and minimum values of each Mehlich 3 P increment of 1 g P/m3 of data in (a). Mehlich 3 P values for Sites 1 and 2 are estimates based on linear regressions with Bray 2 P for each site.
