These are typical soils for this area and are found along <br />most of the major drainages in the area. All of these soils are <br />subject to frequent flooding which limits there uses. A high <br />water table can be present in the early spring and recede to a <br />depth of 48 inches as the season progresses. Adjacent irrigation <br />greatly affects the water table. <br />. As mining operations near completion, all slopes should be graded <br />to a 4H:1V. Generally, the flatter the slope, the greater the <br />chances for adequate grass establishment. All top soil removed <br />during preliminary mining operations should be stockpiled and <br />then spread back onto the slopes and worked or mixed into the <br />slopes. All foreign water should be diverted away from the slopes <br />and not allowed to run down the slopes. <br />In order to determine fertilizer needs, it is highly recommended <br />to take a soil sample and have it analyzed by a professional lab. <br />Unless this test shows differently, no less than 40# nitrogen (N) <br />and 40# phosphorous (P2O5) should be applied per acre. Ferilizer <br />should be applied immediately prior to seeding and lightly worked <br />into the soil. The final seedbed should be well settled and firm <br />but yet friable. <br />Grass should be seeded between Nov. 1 and April 30th. No seed <br />should be put into frozen soil. The following mixture should <br />prove adequate for this site: <br />Blackwell Switchgrass 30$ 1.35#PLS/ac. <br />Salado Alkali Sacaton 10$ .10#PLS/ac. <br />Vaughn Side Oats grama 30$ 2.70#PLS/ac. <br />Rosanna Western Wheat. 20$ 3.20#PLS/ac. <br /> Reed Canarygrass 10$ .40#PLS/ac. <br />TOTAL 7.75#PLS/ac. <br />On all slopes of 3:1 or flatter, a good quality grass drill <br />having depth bands, packer wheels and an agitator should be used. <br />
