Over the last few years, advanced knowledge in cranberry field hydrology has lead to substantial increase in production. Much of this progress has come from knowing the relationship between drainage capacity and soil profile properties. However, drainage problems can occur and an appropriate diagnosis remains essential for making recommendations adapted to each soil type. The objectives of this study were to (1) classify soil profiles under cranberry production and (2) identify diagnostic variables related to drainage capacity. To diagnose and classify drainage capacity, profiles were characterized for many physicochemical and hydraulic properties using a cluster analysis. Results indicate that a criterion can be defined and used to assess drainage capacity with respect to a soil classification scheme based on physicochemical and hydraulic properties. The methodology developed in this study provides a framework to identify local drainage problem and solutions based on soil characteristics.
