Photograph of a close-up of vegetation clipped from 10 sq. ft. deferred pasture (left) and overgrazed pasture (right). The back of the photograph proclaims, "Close-up of vegetation clipped from 10 sq. ft. deferred pasture on left. Overgrazed (1948) on right (Note Weed Growth). No fence between pastures since Oct. last year. Air dry weight for deferred clipping on ac. basis – 4140.9# - 3.1% weeds. Air dry weight overgrazed per acre basis – 2360.5# - 19% weeds by wt. Both pastures meadow until 1948. One year's grazing (over) results against deferred."

Photograph of an UNIDENTIFED man standing in a cornfield planted with vetch. The back of the photograph proclaims, “Corn following 4 crops of vetch. Land prepared for alfalfa last fall – too dry – so corn planted this spring. Vetch was used for pasture. Cut for hay one year yielding 70 bales per acre. Says vetch good pasture and will graze on head per acre during favorable growing season of fall or spring. Johnson grass killed with one deep and one shallow planting in dry weather.”

Photograph of agricultural terraces. Collective terrace outlet sprig sodded to Bermuda grass in March, 1949 and planted to cotton in May, 1949. Cultivation of cotton results in the cultivation of Bermuda grass. The width of the strip is 160 feet and will be fenced and utilized as pasture after grass is well-established and the terraces are constructed. TX-45, 717.

Photograph of the harvesting of 35 acres of King Ranch bluestem grass on the A. E. Bryant farm /ranch. A combine with a spike-tooth cylinder was used. Two days were required to harvest the grass. Mr. Bryant estimates he harvested 1500 pounds of clean seed. Planting was made in the spring of 1947. A good seed crop was harvested in June, a light crop in July and a good yield will be harvested in October. From 2 harvests in 1948 a total of 2500 pounds of seed were harvested. Mr. Bryant needs the following adjustments on his combine for harvesting the crop: the cylinder set at a speed of 1080 rpm; the header set high [unclear] off the air; a ¼ to 3/8 inch clearance on the cylinder; and the reel set forward and down. This is a perennial grass that appears to have a wide adaptation as to soil & rainfall. Note that the grass is waist-high. Planted in 3 feet rows (105 pounds on 35 acres). It has been kept in rows as row plantings tend to yield more than drilled plantings. Bryant has obtained good results by [unclear] dressing this grass with 100 pounds of ammonium sulphate …

Photograph of two UNIDENTIFIED men standing in a class III rangeland. The back of the photograph proclaims, “Class III range land. Blue grama grass is very low state of vigor. Invaders are numerous including muhly grass, fluff grass, three-awn, and perennial broomweed. Erosion, moderate to severe indicating that permanent damage is occurring. Recovery on this type of range will be slow, although much change toward the more desirable species can be expected when the use of range is based upon preserving the grama grasses.”

Photograph of class IV Land Clearance, Cultivation & Brush and Weed Control. Blue grama practically all gone. Most of the sparse vegetation is annual, principally 6-week grama, false buffalo and goat hand, although still remains traces of blue grama, tobosa and burro grass with a scattering of Sphaeralcea angustifolia. Severe erosion. Maria Silty Clay Loam. TX-40, 445.
