Question 1

What is the best way to get an accurate representation of the soil?

Accepted Answer

Using a soil probe, collect multiple cores in the area you are wanting to sample. Place those cores in a bucket and mix together. Fill your soil sample bag to the line with that soil.

Question 2

Most soil sampling instructions tell you to avoid the "bad" or "odd" areas. Why do we want samples from those areas?

Accepted Answer

Calcine is a product that can help fix those areas. If we do not have an accurate representation of what is in the soil in that spot, we might not give them the correct application rate.

Question 3

Can I soil sample in the winter?

Accepted Answer

Yes, but it is not recommended because it can make nutrient values inaccurate. Due to our product rates and recommendations being so dependent on what we see in the soil sample, it is best to wait until spring or fall.

Question 4

When should I tissue sample?

Accepted Answer

Refer to chart in Midwest Labs Tissue Sampling Guide

Question 5

The plant material I sampled has dust on it, is it still okay to use?

Accepted Answer

Avoid collecting samples with dust and residue, however if you do, make sure to clean it off before sending it to the lab. Dust and residue can throw off your values in your test.
