Best Soil Test Kits Buying Guide
Before choosing the best soil test kit you should consider following options:
1. Type of kit: There are three main types of soil test kits: colorimetric, enzymatic, and chemical. Colorimetric kits use a color-changing indicator to show the presence of a substance in soil.
Enzymatic kits use an enzyme reaction to indicate whether a substance is present in soil. Chemical kits use chemicals that react with substances in soil to indicate their presence.
The EPA recommends the enzymatic kits, as they are the most accurate. However, they are also more expensive.
2. Price: Soil test kits can vary in price depending on the type of kit and the number of substances they can detect.
You can get a kit to test for one substance for less than $10, or you can get one to test for eight substances for over $100.
3. Number of samples needed: Some kits only need one sample, but others recommend taking at least four samples from different areas of the property.
4. Results: Not all kits provide the same results. Some kits only show the relative amounts of substances in the soil.
Others give actual numerical results. Some provide results in pounds per acre, while others provide results in parts per million (ppm).
5. User friendliness: A soil test kit should be easy to use, provide clear instructions, and use quality materials. Some kits come with gloves, vials, and sample bags.
You can get kits that are hand-held or ones that are more like a foil pouch. Some kits need to be sent to a laboratory to get results, while others can give you results in the field.
