Agronomic Soil Analysis
Why Test? | Available Tests | Sampling Guide | Submittal Forms | Example Reports
Better yields and top quality can only be achieved through the proper management of all crop inputs. This requires the crop producer, consultant and dealer to have as much accurate information on the grower's fields and crops as possible. Soil testing is the foundation for some of this critical information.
Why Test Soil?
Crop producers cannot afford to waste money on unnecessary crop inputs. Neither can they afford lower yields or quality caused by insufficient nutrients. Crops cannot obtain the needed nutrients, in the required amounts from infertile soil. Also, as each year goes by, the government is imposing more requirements on crop producers to minimize the amount of surplus nutrients that escape from the farm. Soil testing is a tool that can provide some of the critical, basic information to better manage crops, soils, and the environment.

Sampling Guide
Follow the instructions in our soil sampling guide to pull a good representative sample and get accurate results. The greatest inaccuracy in a soil test is the method it was taken.
