Fertile soil is vital to establishing and maintaining productive food plots. BioLogic's pHFertilizer is formulated to provide the vital nutrients necessary to ensure a planting will survive and thrive, helping the deer population to do the same. Carefully calculated quantities of nitrogen, phosphate and phosphorous are blended with finely-ground lime - a revolutionary combination that adds vital nutrients and improves soil pH, all at once. With a single pass, you can provide your food plot with the highest nutrient value possible per acre, deliver a fast-acting lime "spike" to the pH during growing season and provide a lush, green attractant for the whitetail herd. 40-lb. bag.
