Daniel Kaiser grew up on a grain and livestock farm in Northeast Iowa. He attended Iowa State University where he received his Masters and Ph.D. degree in soil fertility researching phosphorus and potassium placement for corn and soybean and phosphorus management using poultry litter. Currently he is an associate professor and extension specialist in the Department of Soil, Water, and Climate at the University of Minnesota where he has a broad research program related to nutrient management for commodity crops in the state of Minnesota. His current research focuses on the use of soil testing and plant analysis for corn, soybean, forages, small grains, and pulse crop production.
One major area of research for Dr Kaiser has been related to the use of sulphur fertilizer in crop rotations in Minnesota. Dr Kaiser has several published articles on sulphur fertilizer of corn, soybean, and hard red spring wheat. The early focus of his research was on revising sulphur guidelines for commodity crops in Minnesota with a focus on identifying conditions where crop responses to sulphur are more likely and the rate of sulphur required to maximize crop yield. His current research focuses on how sulphur is cycled in the soil and when sulphur is most available for crops following fertilizer application.
