Acti-Sol was founded in 1995 and, as egg producers, they developed a technology to recycle the manure produced by the thousands of layer hens in their farms. Natural, abundant & renewable, laying-hen manure is the main ingredient of Mother Hen’s fertilizers and has a centuries-old track record as one of the best natural fertilizers. Because the drying process occurs quickly, no ammonia is formed; it will not burn your plants or your grass. It is rich in calcium & high in organic matter. It is an excellent alternative to chemical fertilizers. In fact, Acti-Sol natural fertilizers are used extensively by organic grain & vegetable growers right here in Ontario.
