Dr. Haby’s career has been undergirded by his resolve to identify and ameliorate conditions that limit crop growth.  His work while with the Montana Agricultural Experiment Station and with the Texas Agricultural Experiment Station/Texas AgriLife Research included the use of soil and plant diagnostic techniques in field, greenhouse, and laboratory studies.  His career-long goal has been to improve crop production efficiency through well thought-out and properly executed soils and cropping systems research.  In Montana, Dr. Haby refined the understanding of fertilizer nitrogen (N) needs for dryland wheat, based on soil nitrate-N levels.  He was a pioneer in establishing the understanding of the effect of both soil and applied N on protein and improved the nitrate-N soil test, demonstrated the interactive effects of N and phosphorus (P), and showed that response to applied potassium (K) was unrelated to K soil test level in high K soils.  He calibrated the sodium bicarbonate soil test in this system.  His other significant research contributions in Montana included: Determined that chloride in potash fertilizers decreased root rot and improved barley yields; Evaluated optimum N management for sugarbeet and corn silage; Resolved the interactive effect of irrigation timing and N rate on safflower production; Related early-season ammonium-N in sugarbeet petioles to highest sucrose production; Evaluated the effects of spent sulfuric acid and gypsum on reclamation of saline-sodic soils.
Dr. Haby’s research contributions in Texas are numerous. He has become a world-recognized authority in crop production on Coastal Plain soils and has been invited to speak at soil fertility symposia in several countries.  Some of his key findings: Liming soils to a pH of 6.2 for clover production and to pH 7.0 for alfalfa production intensified boron deficiency; Demonstrated the benefits of higher limestone efficiency (ECCE) for cool season forage production; Encouraged limestone producers to process and market ECCE 100% aglime as an alternative to the relatively inefficient ECCE 62% product.  His research showed that it is not necessary to have large particles in limestone and that 40% less of the ECCE 100% aglime was needed to achieve the same pH as the 62% material.  Currently, at least 75% of limestone sold by Texas quarries for acid soil neutralization is the high ECCE material. Other significant research contributions have included improved fertilizer practices for bermudagrasses, ryegrass, and clovers; evaluating soil/site properties inhibiting alfalfa as a high nutritive value perennial legume for warm season production on Coastal Plain soils, demonstrating that alfalfa can be successfully grown on selected Coastal Plain soils, and defining the harmful effects of high sodium bicarbonate irrigation water on blueberries as well as the effects of N and P fertilization on blueberry production.
