Uncontrolled application of pesticides can contaminate soil and may kill other nontarget organisms. This study aims to determine the usage pattern of pesticides by farmers in Wanasari Subdistrict and study the soil quality degradation potential. This study was a quantitative and qualitative research.

So, how do you test for pesticide poisoning? Really, I don't know, and it seems that the tests they do have don't always work. Not all pesticides reaching to the soil are biodegradable and such chemicals that show complete resistance to biodegradation are called "recalcitrant".

When to Test for Soil pH. Because most soils are naturally slightly acidic, any reaction at all with this test indicates that you probably have alkaline soil that may require an amendment to bring it to the pH range suitable for most plants.
Make your soil less acidic. If your soil pH tested below 7, add a cup of dolomite or quick lime to the soil. Mix well, then retest with your probe. Certainly, you can use pH strips to test soil. The second method above explains the process for using them: How to Use Paper Test Strips.
