Dr. Larousse Dorissant
Position
- Postdoctoral Research Associate
Research Interests
My primary research interests center on soil fertility, nutrient management, and cropping systems. I am currently working on two main projects:
Understand how the addition of sulfur impacts corn grain yield nitrogen response curve across different environments in Iowa.
Assess the water-solubility and potential mobility of commercially available nitrification inhibitor products.
