The soil testing program starts with the collection of a soil sample from a field. The first basic principle of soil testing is that a field can be sampled in such a way that chemical analysis of the soil sample will accurately reflect the field’s true nutrient status. This does not mean that all of the samples must, or will, show the same test results, but rather that the results must reflect true variations within the field. Remember that the soil test recommendations for lime and fertilizer can never be more accurate than the accuracy of soil sampling.

Once the soil samples have been collected and prepared, the level of available nutrients in each sample must be determined. Many chemical methods have been suggested and are being used for the measurement of essential plant nutrients. The criteria for chemical extracting and analysis of plant nutrients are that those processes must be rapid, accurate and reliable.
