What factor can significantly extend the effective half-life of a common herbicide like glyphosate in the soil?
Answer
High organic matter content or tight binding to soil particles
If the soil has high organic matter content or the chemical binds tightly to soil particles, the effective half-life of common herbicides can extend significantly, potentially lasting months.
