Regular soil testing is a critical component of good crop production. It allows you to monitor soil fertility levels, identify potential for nutrient deficiencies, and make fertilizer decisions based on the best possible information.
The soil test is divided into four main sections, as shown on the Sample Soil Test Report. These are • information on client, sample and field • results of soil test • interpretation ratings for nutrient levels • recommendations for lime and fertilizer applications. Client and Sample Identification.

Soil analysis is a great tool to assess what soil amendments are needed for optimum plant function and yield potential. Soil test results list the soil test concentration for specific parameters along with an interpretation value (low, optimum, and high) and a recommendation.
For each test, the document describes what is measured, recommends how and when to test, indicates levels at which test results suggest deficiencies or excessive concentrations, and suggests solutions to correct soil imbalances.
Soil tests are a valuable agronomic resource if they are fully used and properly understood. Plant nutrition and plant to soil interactions are complex mechanism with a number of environmental and external conditions affecting the process.

All soils are dried in a forced air convection drier at 35°C. All results are reported on this basis and no correction is made to an oven dried basis (103°C). In-house experiments have determined residual moistures to be typically 5%. After drying, soils are crushed to pass through a 2mm sieve.

Oct 3, 2014 · SOIL TEST DATA 17 Nitrate-nitrogen (nitrate-N): Nitrate-nitrogen is reported as lb/acre. Nitrate is mobile in the soil solution and should be tested on the topsoil and subsoil (0-6 and 6-24 inch) for most crops. For deep-rooted crops, like sugar beet or sunflower, nitrate should be tested on the deep subsoil (24-48 inch) as well. Residual soil ...
