Biographical NoteReturn to Top

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.

Arrangement

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.

Processing Note

13	12	13:12:36: On south only fair stand and growth of fall barley; on north quite uniform fair to good growth and stand. Spring crop in foreground obscures differences Plot 07-5A	1956 June 29
13	12	13:12:37: South half of plot almost completely bare; north half shows a rather poor stand with good growth near center of area and poor growth at north edge. Plot 09-5A	1956 June 29
13	12	13:12:38: Growth of fall barley grades from quite good at south to very short and scrubby at north margin Plot 01-5A	1956 June 29
13	12	13:12:39: Fair to poor stand and growth of fall barley, little difference north to south. One better row on east (near) edge; spring crop about the same Plot 01-1A	1956 June 29

13	12	13:12:45: Uniform good stand of fall barley, fair growth, little difference north to south. Spring barley is good and uniform. There is a border of especially good growth along the east edge of the fall crop. Plot 01-2A	1956 June 29
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 Plot 05-2A	1956 June 29
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 Plot 06-2A	1956 June 26
13	12	13:12:48: Fall barley on north half shows good uniform crop; south half smaller less uniform; spring crop same Plot 07-2A	1956 June 26

13	12	13:12:51: Plot 01-3A grades from good at common boundary to only fair at north end; Plot 02-3A has good uniform crop Plot 01-3A & 02-3A	1956 June 30
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. Plots 04-3A & 03-3A	1956 June 30
13	12	13:12:53: Good uniform crop on each Plots 05-3A & 06-3A	1956 June 30
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 Plot 07-3A	1956 June 30
13	12	13:12:55: As indicated by photo plots are nearly bare at common border. Both improve away from this point; 05-4A becomes good to fair at north edge and on east side but has only a pond of water on west side. 06-4A improves regularly to good at south end where it Plots 05-4A & 06-4A	1956 June 30
