B. Use a balanced fertility program based on soil testing that maintains adequate levels of phosphorus, potassi-um, calcium, magnesium and micronutrients. C. Avoid high levels of potassium fertilizer in the upper 4 inches of soil. This can lead to increased incidence of unfilled pods (pops) and pod rot that will affect peanut quality and yield.

Under normal conditions, there should be some leftover N in the soil, which means a reduction in spring N fertilizer applications may be warranted next season. However, too much rain and saturated soil conditions can reduce last season s remaining N. When soils are saturated, significant

Zn uptake. High phosphorus (P) can also decrease concentration uptake of Zn. This interaction is most common in soils that are marginally deficient in Zn. The addition of fertilizer P to soils adequate in Zn will not induce a Zn deficiency. Plant physiological factors may also contribute to the onset of Zn deficiency associated with high P levels.

Treatments were starter nitrogen (N) and diammonium phosphate, and starter N only. Significant treatment differences were not observed for corn or cotton yields (Figure 1, page 2) (Cahill et al., 2008).
