The University of Guelph, Agriculture & Food Laboratory (AFL) offers a wide range of services pertaining to crop health, verification, safety and yield enhancement. We provide a wide range of diagnostic services to assist vegetable, floral, turf grass and field crop growers to manage plant health. By correctly assessing the actual situation affecting plant health, timely preventative actions can be taken which are often much less expensive than curative approaches. Our multifaceted laboratories offer a comprehensive array of physical and chemical analyses that can be used to determine plant/soil fertility and plant health.
