"Organic" Bagged Soil: What the Label Means and GMO Concerns

"Organic" on bagged soil (e.g., Miracle-Gro Organic Choice) has no legal standardization for non-food products. Here's how to evaluate.

What "Organic Soil" Typically Contains

• Composted forest products, peat, coir, perlite, fertilizer (often poultry litter, feather meal).
• No synthetic pesticides/herbicides in ingredients.
• May contain manure from conventional (GMO-fed) livestock.

The GMO/Manure Connection

• 89%+ US corn/soy is GMO → conventional livestock feed.
• Manure from these animals → bagged compost/soil.
• Transgenic DNA/proteins may persist in compost.
• True organic farms: livestock fed certified organic (non-GMO) feed.

How to Choose

• Look for OMRI Listed or CDFA Organic Input Material seals.
• Small, transparent producers > multinational brands (Scotts/Miracle-Gro).
• Make your own: compost + coco coir + perlite + worm castings.
• Resource: Institute of Science in Society — deep data on GMO/ag issues.

Bottom Line

Bagged "organic" soil is a convenience product, not a purity guarantee. For absolute control, build your own mix from verified ingredients.
