Research Scientist

Precision Agriculture & Fertilization of Agroecosystems

Current research and/or projects

  • Study of the utilization of new technologies of precision agriculture such as proximal soil and crop sensing for potato production in eastern Canada

  • Study of the spatio-temporal variability of soil nutrients including phosphorus and nitrogen under potato, forage and grain corn.

  • Study of the utilization of new technologies of precision agriculture such as proximal soil and crop sensing for energy-biomass production using perennial crops

Research and/or project statements

The research program has developed a unique expertise in precision farming for potato growing under eastern Canadian conditions. The use of proximal soil sensors measuring the electrical conductivity of soils allows the determination of homogeneous soil zones within the same field that have similar limitations to yield. These areas can then be managed appropriately to their limitations. The objectives of the program are to increase soil and crop productivity, profitability of enterprises and protection of the environment by delimiting land management areas within the same field. The research is aligned primarily with departmental priorities: (1) increase crop productivity, and (2) enhance environmental performance.

Professional activities / interests

• Precision Agriculture - spatio-temporal variability of soil and crop properties.

• Soil fertility

• Agronomy (potato, corn, wheat, forage)
