Check Your Soil for Herbicide Residue
Friday, March 22, 2019
Learn how to conduct plant bioassays to detect potential herbicide residues in your soil.
Plant bioassays are a simple, inexpensive, accurate and direct method of determining if it is safe to grow crops on land previously treated with known herbicides or on cropland or compost with an unknown history of herbicide use.
A bioassay can detect if herbicide or chemical residues are present in the soil or compost at concentrations high enough to adversely affect crop growth, yield and quality.
