Bee Khim Chim

Bee Khim Chim is an Assistant Professor in the Department of Plant and Soil Sciences at Oklahoma State University (OSU) and Director of the Soil, Water, and Forage Analytical Laboratory (SWFAL). In this role, she leads soil, water, plant tissue, and animal waste analytical programs that support agricultural management, environmental stewardship, and regulatory decision-making across Oklahoma.

Prior to joining OSU, Bee served as an Assistant Extension Professor and Potato Agronomist with the University of Maine Cooperative Extension, where she led applied research and outreach programs focused on nutrient and water management in potato production systems. Her work included field-based trials, grower education, and the development of science-based recommendations to support sustainable production in Northern Maine.

Chim’s current work integrates applied soil chemistry, analytical technologies, and field research to address real-world challenges, including nutrient efficiency, salinity stress, waste management, soil health, and uncertainty in soil and plant testing. She collaborates closely with producers, Extension educators, and researchers to improve how analytical data are generated, interpreted, and translated into defensible management decisions that support long-term agricultural productivity and sustainable agriculture in Oklahoma and beyond.

Research Interests

• Soil and plant analytical systems for agricultural decision-making
• Nutrient cycling, efficiency, and uncertainty in managed agroecosystems
• Waste management: nutrients, contaminants, and risk mitigation
• Salinity stress and soil remediation strategies
• Forage and specialty crop systems under soil and water constraints
