Evaluating Animal Feeds as Lawn Amendments

Corn Gluten Meal: The Proven Choice

Corn gluten meal (CGM) is a byproduct of corn processing, used as animal feed and organic lawn fertilizer. It provides slow-release nitrogen (9–10%) and pre-emergent weed suppression.

Application Rates

• 3–12 lbs per 1,000 sq ft, depending on soil fertility.
• Apply spring and mid-to-late fall.

Why Other Feeds Fall Short

• Cottonseed meal: High in pesticide residues.
• Cornmeal: Likely GMO and pesticide-contaminated; no pre-emergent effect.
• Generic animal feeds: Unbalanced nutrient ratios; may contain medications or additives unsuitable for soil.

Better Organic Alternatives

• Diluted fish fertilizer (liquid, fast-acting).
• Alfalfa meal or pellets (2.5% N, plus growth promoters).
• Composted poultry manure (3–4% N).

Source certified organic amendments from reputable suppliers (e.g., Planet Natural via Avant-Gardening).
