29 When soil test potassium levels are in the 40-60 lb per acre range, a yield response to potassium application is likely only for high yield production (greater than 4,000 lbs per acre) on sandy soils (depth to clay greater than 15 inches) where subsoil reserves of potassium are less accessible. Potash application can interfere with calcium uptake by the pods. If potash application is necessary prior to peanut planting, it should be incorporated with a disk harrow to reduce the concentration in the pegging zone. In peanut rotations, if the previous crop is fertilized to the medium or high potash level, no potash will be necessary prior to planting peanuts.
30 For virginia-type peanuts and all seed peanuts, at bloom, broadcast 1,500 lbs gypsum per acre (or 750 lbs per acre in a 16 – 18 inch band applied over the row). For Spanish and runner types, at bloom, broadcast 1,000 lbs gypsum per acre if soil test calcium is below 700 lbs per acre.
31 This is a boron sensitive crop. Apply 0.5 lbs boron per acre with the broadcast fertilizer or as a tank-mix foliar treatment 30 – 45 days after planting unless the soil test boron level is sufficient. Do not exceed a total of 0.5 lb boron per acre. This is recommended when the fall soil test boron is less than 2.0 lbs per acre.
52 Use a liquid in-furrow inoculant at planting on land not planted in peanuts within the previous three years.
80 Level of soil test zinc is potentially toxic at the current soil pH level. (When soil pH is less than 5.9 and soil test zinc is greater than 5 lbs zinc per acre, or soil pH is less than 6.0 and soil test zinc is greater than 11 lbs zinc per acre, or soil pH is less than 6.1 and soil test zinc is greater than 21 lbs per acre or soil pH is less than 6.2 and soil test zinc is greater than 31 lbs zinc per acre, or soil pH is less than 6.3 and soil test zinc is greater than 41 lbs per acre, or when soil test pH is greater than 6.2 and soil test zinc is greater than 51 lbs per acre)
649 Apply 0.5 lb manganese (2-2.5 lb manganese sulfate or Tecmangam, or 1.5 lb ManGro DF) with both the 60 and 75 DAP fungicide applications. (If soil test manganese is below the sufficiency value at the current pH or the target pH when lime is to be applied)

652 The soil test manganese is low, however, this is not a manganese sensitive crop, therefore no manganese is recommended. (When soil test manganese is low)
