' <br /> recommendations of CDMG, each composite soil horizon sample was analyzed for pH, <br /> electrical conductivity, percent organic matter, texture (percent sand, silt, clay), <br />' estimated lime, nitrate nitrogen, phosphorus, potassium, sodium adsorption ratio <br /> (SAR), calcium, magnesium, sodium, zinc, iron, manganese, copper, selenium, <br /> molybdenum, and boron. Analysis results are presented in Table 3 for each horizon. <br /> Analyses were made using standard extraction techniques for soil analysis. Nitrate <br /> nitrogen, phosphorus, potassium, zinc, 'von, manganese, and copper were analyzed <br />' through an ammonium bicarbonate-DTPA extract. Selenium and molybdenum were <br /> analyzed through use of a hot water extract technique. Boron was evaluated using a <br />' saturated paste technique. <br /> Vegetation Sampling <br />1 <br /> Four vegetation parameters were sampled to evaluate the vegetative condition of the <br /> study area. Vegetation cover, total herbaceous production, species composition, and <br />' woody plant density were the parameters for which quantitative data were collected for <br /> the historic record vegetation community. <br /> V~etation Cover <br />' Vegetation cover was estimated by the use of the point-intercept method. An ocular <br />point frame (ESCO Associates) was used to minimize instrument error and maximize <br /> precision and observer accuracy. Cover transects were 25 meters in length, with two <br /> sample data points collected at 1.0 meter intervals along the transect on opposite sides <br />' of the transect centerline, 1.Sm apart. Transect direction was established randomly. In <br /> no event were transects allowed to extend within ten feet of the study area boundary or <br /> disturbed areas (e.g., two track road, stock pond) to minimize impacts from "edge <br /> effect." <br />For statistical purposes, each cover transect (wmprising 50 data points) served as a <br />sample unit. Data points recorded the first vertical "hit" on vegetation (above or below <br />the instrument), bare ground, rock, or litter. Subsequent "hits" on vegetation were also <br />' recorded. Cover data were recorded and reported by individual plant species. The first <br />interception was used to calculate total cover values. Additional interceptions were <br />used to calculate relative cover of individual plant species and lifeforms. The <br />quantitative cover data also provided the basis for calculation of species composition. <br />' Herbaceous Production <br />Herbaceous production was estimated by the harvest method. One herbaceous <br />' production plot was located and randomly oriented at the end of each cover transect. <br />Additional herbaceous quadrats were located randomly as described above. Herbaceous <br />production plots were 0.50 square meters in area. All current year above ground live <br />' herbaceous plant biomass was clipped within the 0.50 square meter quadrat.
