Jolt Foliar Fertilizer is easy to use - just mix with water and spray over any food plot after plants are at least 3" tall. With conventional dry granular fertilizer, you have to hope that it will rain to dissolve the granular fertilizer and wash it down to the roots of the plants. Without a timely rain, you risk the granular fertilizer burning the plants you're trying to help grow. With Jolt, you can optimize your plot's potential for maximum tonnage. By spraying the Jolt solution onto the stem and leaves of the plants, it is similar to spoon-feeding the plant an efficient and readily available fertilizer. One 32-oz. package covers a 2-acre plot or covers a 1/2-acre plot 4 times.
