Our most nutrient rich fertilizer.

Enhance is our most concentrated fertilizer supplying NPK directly to the root zone with every application, anytime of the year.

Any Crop, Any Soil, Any Time
Enhance is a clean, concentrated, low salt fertilizer formulated to benefit plants throughout the entire season. This blended fertilizer can be applied to irrigation water for fertigation feeding or added to spray tanks for foliar feeding. Ideal for all applications, Enhance was formulated to give the grower ease of application while supplying the plant with an abundant amount of phosphorus and potassium. Enhance is formulated with 100% orthophosphoric acid, which provides immediately available phosphorous for plant uptake. The neutralized potassium hydroxide in the mixture is also immediately available.


Promotes Growth
During periods of rapid growth, Enhance should be applied to provide the crop with concentrated amounts of readily available phosphorus and potassium along with nitrogen. Enhance is the ideal fruiting fertilizer developed to improve yields and crop quality.


Neutral pH, Concentrated Formula
Enhance is non-corrosive and highly concentrated to supply the grower with an optimal soil or foliar applied fertilizer. Because of the excellent stability of the formulation, Enhance won’t settle out in the tank, resulting in uniform flow throughout your fertigation system.


Carbon Boosted
Straight Arrow’s Enhance Concentrated Low Salt Fertilizer is an innovatively formulated “Carbon Boosted” fertilizer developed to supply a power punch of carbon and other readily available plant nutrients. Straight Arrow™ Organic Acids make this all possible. These organic acids are anion based and loaded with carbon chains to provide optimum uptake. Our “Carbon Boosted” fertilizers work as a natural plant metabolite, enhancing fruit quality, plant production, and crop yields.
