. _. ,~ <br />• Soils Report--Snowmass Coal Company, Alfalfa Planting <br />Six samples of soil were presented for analysis in November, 1987 from <br />Snowmass Coal Company. The samples represent an area that will be planted <br />to alfalfa in the spring of 1988. The samples were air-dried, ground to <br />pass through a 1 mm sieve, and subjected to various cnemical and physical <br />analyses. A separate sub-sample caas kept unground for textural analysis. <br />Fertility Characteristics <br />The fertility of the soil samples are presented in Table 1. A surpcising <br />amount of residual nitrate-nitrogen was found, and sample number 6 tested <br />in the "high" range. All other values were in the "medium" range. Phosphorus <br />tested low to medium, and potassium tested medium. Most phosphorus values <br />were in the medium range. Aficro-nutrient levels (iron, zinc, manganese, and <br />copper) are high. Fertility recommendations will be given in a later section <br />• of this report. <br />Salinity Characteristics <br />Salt contents of the soil samples are relatively low and should not <br />present any cause for concern if the area is well-drained and irrigated <br />properly. The pH's of the soils are slightly basic, and indicate a normal <br />situation for the area. The sodium adsorption ratios are quite low. <br />Physical Characteristics <br />The organic matter content of the soils is relatively higi~ which indi- <br />cates that the area supported good vegetative growth at one time. The texture <br />is a silt loam, and should not present any difficulty with respect to tilth. <br />Slightly heavier soil is represented by samples 5 and 6. Some crusting may <br />be encountered. The saturation percentages reflect the texture. <br />• <br />
