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

Figure 2b. Relationships between pre-crop (a) water-extractable P or (b) acetic acid-extractable P for individual zero P plots and relative sugar yield without fertilizer P. Zero P relative sugar/acre 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. The index in Figure 2b refers to both graphs. Mehlich 3 values for Sites 1 and 2 are estimates based on linear regressions with Bray 2 P for each site.
