Soil analysis is the best method of determining what nutrients or fertilizers and how much of those fertilizers are needed to prevent crop nutrient deficiencies and optimize crop yields.

[Slaton walks into a field with a bucket and soil probe. He pushes the soils probe into the soil and puts the sample collected into a bucket.] Collecting soil samples from late October or early November through March should produce consistent results that provide similar fertilizer recommendations. 

[[Slaton walks into a field to to collect a soil sample using a soil probe. Text slide - Collect your soil samples between late October to early March to ensure consistent results.] We recommend collecting soil samples near the same time of year each time the samples are collected, and following the same crop grown in the crop rotation sequence.

[Slaton walks into a field to to collect a soil sample using a soil probe. Text slide - Samples should also be taken prior to applications of fertilizer or manure to your fields.] Soil samples should also be collected before any fertilizer is applied or manure is applied to the fields. [Text slide - 15 - 25 soils cores equals 1 composite sample.] Generally we recommend 15 to 25 individual soil cores to be collected to represent one composite sample.

Soil probes can either be homemade or bought.  [Slaton shows an example of a homemade soil probe made from a long, hollow cone shaped cylindrical tube with a large washer welded to the tube set at four inches attached to a long wooden handle.] This is an example of a homemade one that we use in our research program, which is simply stainless steel, and we have welded a large washer at the soil sample depth. For this particular probe is 4 inches. The washer ensures that the probe will not go below a 4 inch depth.

As a reminder, collecting soil samples is arguably the most important component of the soils analysis process. So make sure to take your time and take the soil samples properly to get the best fertilizer recommendations.

If you have questions or comments about taking soil samples or how to get soil analyzed, please contact your local county extension office.
