Soil testing is an integral part of a soil fertility management program. Effective soil testing provides information on the fertility status of soils within a field that can be used for making fertilizer or lime application recommendations, monitoring changes in soil fertility over time and even identifying and targeting low-fertility soils within larger fields. Informative soil sampling can improve on-farm nutrient efficiency, leading to increased return on investment for fertilizer and lime application and decreased risk of off-site nutrient movement. Regardless of the goal, reliable soil testing starts with proper soil sampling. In this article, we will outline the basic principles of agronomic soil sampling, covering the basic principles of soil sample collection and providing guidelines for establishing an effective soil sampling and testing program.
