Photograph of young purebred bull calves on Dallis grass-white clover summer pasture. Through the last several years this field has come into a solid stand of Dallis grass and white clovers. Seeding has occurred mainly from droppings from areas previously established with Dallis grass and clovers. Also seeds have beebn spread by feeding Dallis grass-clover hay. One ton of lime each 8 years and 300 pounds of super-phosphates each 3 years are being applied to this field. This pasture, according to Mr. Wyatt, has a carrying capacity of a cow and a calf per acre. This farm unit consists of some 90 acres of Bermuda base pasture and 10 acres of Dallis grass pasture. The pasture supports some 50 purebred beef cows for some 10 months per year. Land Capability Class I 7-FC. Slight erosion.

Photograph of a cow grazing on Big Hop Clover, which was seeded over with Bermudagrass on the Dick Elliott farm south of Soper. The back of the photograph proclaims, "Cow grazing Big Hop Clover which was seeded over Bermudagrass Note stand of Clover and excellent condition of the cow. On the Dick Elliot farm south of Soper."

Photograph of flood damage to agricultural land. Field was retired from cultivation and prepared for seeding and sodding to Bermuda and bur clover. Before operations were completed 4 1/2" of rain fall and runoff from this rain together with overflow water of Crowder Creek, tributary of Muddy Boggy River, caused heavy loss of topsoil frombare field.

Photograph of front view of a easy -flow fertilizer spreader adapted fro Bermudagrass seeding. Holes are adjusted to plant 4-24 inch rows. Seed is mixed with 5-10-5 fertilizer and planted at the rate of 2 lbs. of seed and 200 lbs of fertilizer per acre. The seed is dropped in small furrows that are made by spring-tooth harrow teeth. Press-wheels train in the furrows. Cost of this conversion is about $65 worth of material plus labor.
