 Biographical Note

Lyman Sessions Willardson was born in Ephraim, Utah on May 10, 1927 to Lyman Young Willardson and Alice Sessions. He attended Snow Junior College graduating in 1948 with an Associate of Science degree in engineering. On October 8, 1948 he married Vivian Berrey in Evanston Wyoming and together they had six children. Lyman obtained a Bachelor of Science degree in Civil Engineering with a speciality in irrigation from Utah State Agricultural College in 1950. After graduation, Lyman worked for the U.S. Soil Conservation Service in Logan while working towards a master's degree. In 1952 he moved with his family to the Dominican Republic to accept a position as an irrigation engineer with the United Fruit Company. He joined the Agricultural Experiment Station of the University of Puerto Rico where he conducted irrigation and drainage research from 1954 to 1957. He returned to Logan, Utah as a research irrigation engineer with Utah State University. In 1965 he attended Ohio State University completing a Ph.D. in agricultural research. He then moved to Imperial Valley in California where he continued to work in irrigation and drainage engineering research for the Agricultural Research Service in the USDA. In 1974 Willardson returned to Logan becoming a professor of Irrigation and Drainage Engineering at Utah State University. He officially retired in 1994 but continued to teach and conduct research until the spring of 2005. He passed away on October 5, 2005.

The Lyman S. Willardson photograph collection consists of 13,798 slides, prints, and negatives. These images document his research in agriculture and irrigation as well as his travels. Included are irrigation projects and water experiments throughout the United States including Montana, Wyoming, Nebraska, California, Colorado, Utah, New Mexico, Arizona, Ohio, Indiana, North Dakota, Idaho and Washington, and overseas in Egypt. Also included are images of presentations, charts and graphs, lab equipment and machinery, and laboratory experiments.

The Lyman S. Willardson photograph collection is arranged by slides, prints and negatives. A number of slides were already numbered so those have been retained, however, some slides were missing from the collection so there are skips in the numbering system. In some cases, the prints and negatives were found together and were then processed to reflect this but the majority of boxes 14 and 15 consist of negatives whose prints were not matched.

Plot 10-1A

 13 12 13:12:4 Conditon of fall barley obscured somewhat by soring barley near camera. Fairly uniform on north except for bare spot in N.w. corner; very poor spotted stand and growth on south half; north half of spring crop is good; there is a bare spot in s.w. corne 1956 June 29

Plot 04-2A

Plot 03-1A

 13 12 13:12:6 Looking southeast. Photo taken to show the very good growth in southeast corner of plot and bare area in southwest corner. Note that east side of north half is much better than west side. 1956 June 26

Plot 05-2A

 13 12 13:12:7 Facing north. Tractor was stuck here during initial land prepartion. Water in depression never drains away, apparently lost only by evaporation. Crop is fall barley. 1956 June 30

Plot 05-4A & 06-4A

 13 12 13:12:8 A narrow band, one or two drill rows wide, along east edge of good growth tends to mask true treatment effects. The plot as a whole has a poor stand and very poor growth, there is essentially no growth where marker stands. 1956 June 29

Plot 03-2A

 13 12 13:12:9 Fair rather spotted stand; poor growth with little difference from north to south spring or fall. 1956 June 23

Plot 09-1A

 13 12 13:12:10 Poor stand and growth of fall crop on south portion; fair stand and growth to north; one row along east (near) edge is much better and masks real condition. Spring crop good and uniform. 1956 June 29

Plot 02-2A

 13 12 13:12:11 Very good crop of fall barley on south; fair to good on north half, rather short stalks. 1956 June 30

Plot 01-6A

 13 12 13:12:14 Very poor stand and growth of fall barley except for narrow band along east (near) edge. There are many bare spots 1956 June 29

Plot 01-6A

 13 12 13:12:15 The plow shows a quite uniform stand from north to south, but growth varies from good at east (near) edge to very short at west edge. The change in height is gradual over the whole plot. 1956 June 29

Plot 09-6A

 13 12 13:12:16 Fall barley. Note bare area to left (south) better stand to right. There is a thin (2 feet) band of better growth along east edge of plot (near camera) 1956 June 29

Plot 02-6A

 13 12 13:12:17 Note much better fall barley on north half; bare on south except for narrow band around margins. 1956 June 29

Plot 03-6A

 13 12 13:12:18 Growth of fall barley on north is 2 feet or more tall that on south 1 1/2 - 2 feet high. Growth on whole plot is evenly spaced, there are no bare spots. Crop on south half is more nearly mature 1956 June 29

Plot 04-6A

 13 12 13:12:19 Stand of fall barley uniform and almost two feet tall 1956 June 29

Plot 05-6A

 13 12 13:12:20 Fall barley is short and uneven in height; there are some bare spots, an especially large one is located in south half. 1956 June 29

Plot 06-6A

 13 12 13:12:21 Note border of good growth along east edge (foreground) which obscures true growth. Growth on north fairly uniform and about 1 1/2 feet tall; south half scrubby about 1 foot tall with thin stand. Fall Barley. 1956 June 29

Plot 07-6A

 13 12 13:12:22 Fall barley. The east (near) margin, a little less than half the plot is quite good. The west half of plot is quite uniformly short scanty growth, possibly slightly better to the north. The thin stand can be seen behind marker 1956 June 29

Plot 08-6A

 13 12 13:12:23 Plot 01-4A has a fair growth and stand, possibly slightly better to north; plot 02-4A has a uniform good stand, little difference from north to south. 1956 June 30

Plots 01-4A & 02-4A

 13 12 13:12:24 Both plots show fair to good uniform stand and growth. There is little difference between plots or from north to south within 03-4A. The north half of 04-4A is slightly better than south half. 1956 June 30

Plots 03-4A & 04-4A

Plot 08-3A

 13 12 13:12:28 Good uniform growth and stand; no difference norh to south; note that south part of plot 06-4A is about the same as this plot 1956 June 30

Plot 07-4A

 13 12 13:12:29 South half bare; north has short scrubby scattered growth of fall barley 1956 June 30

Plot 08-4A

 13 12 13:12:30 North half fair growth but uniform stand; south very good on east (near) edge and grading steadily poorer to the west edge, quite uniform north to south 1956 June 30

Plot 01-5A

 13 12 13:12:31 Quite uniform poor growth, stand a little spotted; little difference north to south 1956 June 30

Plot 02-5A

Plot 01-2A

 13 12 13:12:46 North half where marker is located has a fair stand with poor growth along east edge of south half there is a narrow, 6-12 inches; band of good growth; rest of south half is essentially bare. Spring crop much better, although there is small bare spot in 1956 June 29

Plot 05-2A

 13 12 13:12:47 Good uniform growth of fall barley on south half; on north there is a narrow band about 2 feet wide on east (near) edge which is quite good, rest of north half short with only a fair stand. The spring planting is quite good; possibly slightly better on 1956 June 26

Plot 01-3A & 02-3A

 13 12 13:12:52 In general these plots have a good crop. Near the middle of each is a zone where growth is restricted so that top of crop has a wavy appearance, low in the middle, high at the common boundary and then low again. These plots had near the highest-yield. 1956 June 30

Plots 05-3A & 06-3A

 13 12 13:12:54 Check plot. Bare on south; some scattered plants to north. On extreme north both spring and fall growth is very good; undoubtedly this is a border effect caused by leaching water breaking across or by leached soils in dike being carried over on to plo 1956 June 30
