Kingston Agronomy Inc. dba Kingston Agriculture Services (Kingston Agriculture) markets, sales and distributes a nontoxic all natural food grade plant food marketed as Kingston HF (HF stands for “humic fulvic”).  

Kingston HF lets growers reduce the amount of nitrates that are required for healthy plant growth.  This is accomplished by using nutrients that already exist in the soil, with the Kingston HF plant food acting as a foliar feed to the plants.  Foliar feeds are applied directly to the leaves of the plant, thereby supplying nutrients via the leaf to the root system.

Kingston HF is being used across the United States in a variety of growth and production environments.  Some of the products include citrus, vegetables, golf courses, lawns, sod fields, turf, ornamentals, and pasture lands.

The advantage of Kingston HF is that as an all natural feed, it takes advantage of pre-existing nitrates, phosphates, and potassium in the soil.  These exist in soil as a result of years of build up from agricultural treatments.

Kingston Agriculture has over 15 years experience in the development and application of foliar feeds.  Foliar feeding helps to reduce nitrates, phosphates, and potassium in soil.  The expertise of Kingston HF is in balancing and conditioning soil via foliar feeds to obtain maximum growing efficiency in all types of growing environments and conditions.
