You might already know that soils contain a rich variety of life besides your plants. Soils that are teaming with life produce more vegetables and fruits, and more lush lawns and green spaces than sterile soils. Fungi can develop symbiotic relationships with plants that enhance plant growth; other organisms convert plant waste and aerate the soil. Some pollinating insects make nests in the soil. When you maintain healthy soil, you can reduce the need for fertilizer and pesticides. Over use or misuse of pesticides can damage your soil.
Pesticide residue in soil may come from pesticide applications that happened long ago, pesticide applications made more recently for termite control or pesticides that were applied somewhere else. Many termiticides bind tightly to the soil, and they are intended to last a long time. The soil where the pesticides have been applied should not be disturbed to maintain the barrier around your home and to prevent exposure to the pesticide-treated soil. If you have questions about pesticide soil residue in organic farms or gardens, check with your certifying agent, or call NPIC for assistance.
