3.0 Results <br />• phosphorus. Only one sample contained concentrations of phosphorus that were high enough to be <br />considered marginal. <br />Based on the results of the soil analysis, phosphorus fertilizer recommendations were developed for <br />future programs (Table 12). For soils having low concentrations of phosphorus, an application of <br />phosphorus (as phosphate or PZOS) at a rate of 60 lbs/acre is recommended. For soils having <br />magginal concentrations of phosphorus, an application rate of 30 Ibs/acre phosphorus is <br />recommended (Table 12). Organic materials such as manure or biosolids can provide significant <br />amounts of phosphorus to soils. <br />3.5.6 Potassium <br />Concentrations of potassium in soil samples ranged from 111 ppm to 338 ppm. Concentrations of <br />potassitun ranging from 60 to 120 aze considered medium. Only two soil samples were found to <br />contain marginal concentrations of potassium. All other soil samples were found to have high <br />concentrations of potassium. <br />For soils having potassium levels below between 60 and 120 ppm, application ofpotassium (as Kz0) <br />at a rate of 401bs/acre is recommended. One of the most common sources of potassium is potash. <br />3.5.7 Zinc, Iron, Manganese, and Iron <br />• Concentrations ofmicro-nutrients, including zinc, iron, manganese, and iron were also measured in <br />all soil samples. In general, soil samples were found to have adequate concentrations of micro- <br />nutrients. One sample (SS6) had slightly low concentrations of zinc at 0.85 ppm (I.0 ppm is <br />generally considered adequate). However, this zinc concentration is not considered to be low enough <br />to affect revegetation success. <br />RevegetationSurveyReport•RPI'(b26)Revl.dodseptember b, ?001 14 <br />
