The back of the photograph proclaims, “Buffalo grass sod with root system exposed showing how the matt of roots forms an erosion resistant net. At the left is a runner which if undisturbed would have started new grass plants at each group of blades. Taken to illustrate an article by Mr. Ivy Howard.”

Photograph of cotton rows growing on the contour on the side of the hill, while alfalfa grows at the bottom of the slope on the Marion Bryant Farm. The back of the photograph proclaims, “The cotton rows are on the contour on the side of the hill, while the alfalfa is at the bottom of the slope. In former years when the cotton was farmed in straight rows up the slope, there was a great deal of washing in the sandy soil of the cotton field and the silt was deposited in the alfalfa, threatening to destroy it. The cotton field was then contoured and since then there has been no damage to the alfalfa below.”

Photograph of a cotton field that is unnecessarily terraced to prevent erosion on the R. O. Haddock Farm. The back of the photograph proclaims, “On long gentle slopes it is not necessary to terrace fields to prevent erosion. Here we have a field, which is planted to cotton on the contour. This slope is very good for the prevention of erosion, but when these cotton rows have a strip of some sown crop at intervals on the contour, erosion is practically eliminated. The sown strip here is maize."

Photograph of a field of cotton on the contour with strips of Sudan on the contour on the intervals on the W. W. Brown farm. The back of the photograph proclaims, "This shows a field of cotton on the contour with strips of Sudan on the contour on the intervals. On long gentle slopes erosion may be prevented by planting the row crops on the contour and then at intervals placing a strip of sown crop that varies in width to take up the irregularities and this will eliminate all short and point rows."

Photograph of a V-shaped patch of sown cane on the B. A. Howard farm, which is used to eliminate any point rows in the field of cotton, which is contoured. The back of the photograph proclaims, "This is a V-shaped patch of sown cane, which is used to eliminate any point rows in the field of cotton, which is contoured. Irregular strips and points such as this one are easily handled by planting them to some sown crop, which can be used for forage or hay. This enables the farmer to use all the land in the field without having a number of short rows when contoured."
