Once you have prepared your soil sample, you can move on to using your soil organic matter tester and other soil testing tools.
Conducting the Soil Organic Matter Test
Once you have obtained your soil organic matter tester, you are ready to conduct the soil organic matter test. Here are the steps you need to follow:
- Collect the soil sample: Collect a representative soil sample from the area you want to test. Use a soil auger or shovel to collect soil from a depth of 6-8 inches. Take multiple samples from different spots and mix them together to get a composite sample.
- Prepare the soil sample: Remove any stones, roots, and debris from the soil sample. Break up large clumps of soil to ensure there are no air pockets. Allow the soil sample to air dry for a few hours if it seems too wet.
- Insert the tester into the soil: Insert the probe of the soil organic matter tester into the soil sample at a depth of 2-6 inches. Be sure to push the probe all the way in and avoid hitting any hard objects like rocks or roots.
- Record the reading: Wait for the tester to display the reading on the digital screen. The reading will indicate the percentage of organic matter in the soil sample. Record the reading on a piece of paper or in a notebook.
- Repeat the test: Repeat the steps above to take additional readings from other areas and depths. This will allow you to get a more accurate representation of the organic matter in your soil.
- Interpret the results: Once you have taken all the readings, you can now interpret the results. A soil organic matter percentage of 2-3% is considered low, 4-6% is moderate, and above 7% is high. You can then use these results to adjust your soil management practices or determine what kind of crops or plants will grow best in your soil.
Conducting a soil organic matter test is a relatively simple process that can provide valuable information about the health of your soil. By following the steps above and interpreting the results, you can make informed decisions about how to improve your soil's organic matter content and ensure the success of your crops or plants.
