Professor Green products have been formulated and used by agriculture and sports facility managers (Golf Course Industry) for the past 35-year. These products have not been available to the home gardener. These products have been formulated with ingredients that until now are specifically designed to increase crop yield and to optimize the health and vigor of crop production. Agricultural liquid fertilizers and soil conditioners are developed with a science that is far superior to any lawn and garden product on the market. Lawn and garden fertilizers were not designed to grow crops, that"s why you won"t see a farmer go into a store to purchase a 100-gallon of fertilizer, it won"t increase yield in crops and vegetable gardens grow crops. It takes many-year of exhaustive testing and great expense to develop products for crop production. There are a few steps that farmers engage in to insure healthy and abundant yields. The farmers next action is to feed the plant, all of EnviroWise Fertilizers and Soil Conditioners have the complete science of agriculture behind them and are formulated with a perfect blend of nutrients for the highest performance for all of your lawn and garden needs. If you want the same results that farmers and golf course superintendents receive, doesn"t it make sense to use the same products they do.
