Research & Extension Activities:

Luke Gatiboni is a professor and extension specialist in soil fertility and nutrient management. Luke teaches Soil Fertility in the Graduate Program in Soil Science and leads an applied research and extension program in Soil Fertility focused on North Carolina cropping systems. His program aims to develop and refine soil test-based nutrient and lime recommendations to maximize yields and profitability while minimizing nutrient losses. Among the ongoing projects, Dr. Gatiboni is conducting studies on: (a) P and K soil test correlation and calibration using long-term trials and on-farm trials; (b) Impact of saltwater intrusion on cropping yields and mitigation of salt-affected soils; (c) Response of crops to lime and gypsum application.

The extension activities encompass producing Extension publications, as well as providing technical support and training to NC Extension Agents, crop consultants, and North Carolina farmers.
