Espoma has been around a long time and have been authentically involved in producing organic fertilizers since before it became a hot field. Some of their products are “bridge” or “organic based lawn fertilizers” and not truly organic, but they do offer truly organic lawn fertilizers as well. Espoma Organic Lawn Food is a 9-0-0 analysis and is designed for use on your lawn at any time of the year. If you’re going to use Espoma Organic Lawn Food, you’ll probably want to do 4 treatments per year using 5-10 lbs per thousand square feet with each treatment. In the Midwest, you can follow the Easter, Memorial Day, Labor Day, Thanksgiving schedule of applications. I’d put down the heavier rate on Easter and Labor Day while leaning towards the lower rate on Memorial Day and Thanksgiving.
Feather Meal and Poultry Manure. The Poultry Manure is listed as pasteurized which means that they heated it up to destroy any pathogens. The plus side of this is obvious, but the downside is that the pasteurization also kills good biological life that would really help your soil. A better method than pasteurization would be composting which would also kill pathogens but would preserve more organisms. Espoma tries to solve that problem by adding beneficial bacteria to the product which can help, but won’t provide the full array of microbes that composted poultry manure would provide.
It makes good sense to use all parts of the chicken and not waste them. From this perspective, it’s a great organic choice. Some organic fertilizers made from poultry by-products can have a strong odor, but it should dissipate within a day or two.
We offer a Good Nature Earth Turf Spring and Fall Blend. Each blend contains Corn Gluten Meal (as well as some other vegetable based meals) which can help suppress annual weed germination. So, the difference between Good Nature Organic Lawn Fertilizers and Espoma Organic Lawn Fertilizer is that Good Nature uses vegetable meals as the base source of protein and Espoma uses Poultry by products.
The advantage to Good Nature's blend is that the vegetable protein meals offer some natural weed suppression and the vegetable meals are not animal based and don't have that smell you might associate with poultry litter fertilizer.
Granular Organic Lawn Fertilizers are heavy and a little bit expensive to ship, so if you can find a good source locally, that is a great bet. Just read the label.
