Professor of Agriculture
B.S., Texas A&I University, Plant Science, 1970;
M.S., 1972, Soil Fertility, Iowa State University
Ph.D., 1976, with major in Soil Fertility & minor in Animal Nutrition, Iowa State University

Courses:

AGN 110, Crop Science. Taught in long semesters.
AGN 331, Soil Science.  Taught in long semesters via the Web and face to face in the summer.
PLS 420, Ag Waste Management. Taught once per year in spring or summer.

Dr. Young came to Stephen F. Austin in 1975 to run the Soil Testing Lab. He served as Department Chair from 1984 to 1997. Dr. Young continues to be involved in soil testing activities, especially through research. His current research and public service efforts include:
 

  1. Potassium fertilization of improved bermudagrass. 
  2. Use of broiler litter as a fertilizer material and its subsequent effects on surface water quality.
  3. Litter Marketing Project which includes the Texas Poultry Litter Hotline. 
  4. Use of Ca, Al, & Fe compounds to stabilize P on heavily manured soils.
  5. Member of the East Texas Regional Water Planning Group.
     
During his tenure as Department Chairman, Dr. Young supervised the construction of the swine and poultry facilities at the Agriculture Science Center in the late 1980's and the equipment for the Feed Mill in the mid 90's (Dr. Tim Cherry completed the Feed Mill instillation in 1998). Major equipment purchases were made for the farms and the Department during his tenure as Chair. He has encouraged the continuous revision and improvement of curriculum with the objective of better training of B.S. graduates for employment in the agricultural industry.

Dr. Young is married to Loraine, the Love of his life.  They have four children:
 
bulletMatthew, a Poultry Science graduate from SFA in 2001, currently working for Baptist Student Ministries and attending Seminary in Portland, Oregon.
bulletApril, a 1999 graduate of SFA, who spent 2 years in Mexico working as an English Teacher, currently teaching Spanish at Lake Highlands High School in Dallas
bulletDrew, a former high school football player (offensive center), is currently enrolled at Texas A & M as an Ag Development major.
bulletMolly, attends Nacogdoches High School, is active in Choir and and youth activities at church, and is interested in the performing arts.
Dr. Young is a contract grower for Tyson Foods in his spare time (5 houses with total capacity of  about 95,000 birds).
