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 crop 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. EnviroWise Soil Enhance is the only Humic Acid that has had an extensive 3 year study by the USDA for its highest effectiveness in crop production, it has shown to increase crop yield by 30%. The most important thing a farmer can do is to feed the soil, EnviroWise Soil Enhance increases the all important Organic matter in the soil and restores nutrient levels to their proper balance, plants cannot thrive without a proper nutrient balance in the soil.
