Today the Yuma branch stations combined are composed of 514 acres (Yuma Valley 274 acres and  Yuma Mesa 240 acres). This acreage was obtained by The University in four different parcels at four different times (A,B,C & D).

A) The Yuma Mesa citrus Farm - 160 acres. The land was purchased with state funds in 1919, located seven miles south of Yuma Mesa. The soil is classified as a superstition fine sand and is farmed predominately in citrus and legumes. Adequate irrigation water is available and is purchased from  the Unit B Irrigation and Drainage District on contract. One hundred and seven (107) acres of this farm is leveled and in crop, the balance being too rough to be leveled economically.

B) The Gila Project Farm - 70  acres. This land was deeded to the University in 1938 by the Bureau of Reclamation. The land was donated to assist in "research on water conservation and crop economics". The research conducted here was to help pave the way for passages of the Yuma Mesa Division on the Gila Product Bill before Congress and the ultimate development of that 25,000 acre project. The soil is classed as superstition fine sand and is best adapted for cropping in citrus and legumes. An adequate water supply is provided by Yuma Mesa Irrigation and Drainage District, whose source of water is the Imperial Dam on the Colorado River. This farm is located adjacent to the Yuma Mesa Citrus Farm.

C) The Yuma Valley Farm - 160 acres. This farm was purchased in 1954  from state funds, the site was selected cooperatively by a committee from the Yuma County Agricultural Research Council and Experiment Station Representatives. The elevation is 100.7 feet above the sea level. In October 1954, Yuma area farmers completely leveled 80 acres of this farm at no cost to the University.

The soil is classed as Gila silty clay loam. Many who work this land would delete the word loam from the classification. It is very fertile land, but the lack of soil uniformity limits the acreage available for research projects. This farm has an adequate water supply which is available when need and previously schedule with the Water District. The Yuma Valley project has the second oldest water right on the river, dating back to 1905.

D) The Sturges Farm - 114 acres. In 1959, Mr. Steve Sturges, a prominent Yuma farmer, donated a state lease to the University for research purposes. Mr. Sturges had a long term lease, with a 45 acre cotton allotment, which he gave up to further the research potential of the experiment station. We are all grateful for this faith in our work and for his generosity.

This farm is located ¼ mile north of the other Yuma Valley Farm. It is classed as Gila silt loam and is very productive and uniform land . Adequate water is supplied by The Yuma Valley Irrigation District.
