What is Corn Gluten?
One of the most important discoveries in organic lawn care has been the accident Corn Gluten. Discovered by mistake at Iowa State University researcher Nick Christians, has been a giant breakthrough. This organic product (made from Corn Gluten Meal) is a natural herbicide that has been patented and sold by many companies as an alternative to Weed and Feed products.
Corn Gluten Meal is a powdery byproduct of the corn milling process. Used for years as a supplement in hog feed, this natural protein is very effective for lawns and gardens as a plant food as well as a weed suppressor. Corn gluten meal products offer a non-toxic, yet effective alternative to traditional, chemical-based weed and feed products for weed control in gardens and lawns, paths and driveways.
As a plant food, corn gluten has a N-P-K ratio of 9-1-0, or 10-percent nitrogen by weight. As a weed suppressant, corn gluten acts as a natural “pre-emergent” – it inhibits seed germination by drying out a seed as soon as it cracks open to sprout. These qualities make corn gluten an ideal ‘weed n feed’ product.
