BLACKJAK is a concentrated aqueous mixture of humic, fulvic and ulmic acids that is suitable for soil (broadcast, band, drip) and foliar application. It can be used alone or mixed with a wide range of plant protection and plant nutrition products (it is recommended to do a jar mix test prior to use). Its naturally acid pH enables growers to also use it with acidic fertilizers or to reduce the pH in alkaline tank solutions. It may improve the uptake and speed of action of foliar fertilizers. It also can enhance root development.
BLACKJAK has been successfully used on tree crops, vegetables, cereal crops, grapevines, potatoes, onions, corn, sugar beets, sunflower, strawberries, etc.
Humic acids are natural chelating agents so soil applications of BLACKJAK help to mobilize macro and micro nutrients. When used in heavy clay soils BLACKJAK may help break the clay bonds potentially making the soil lighter leading to an increase in microbial activity, air and water circulation and water retention.

MIXING INSTRUCTIONS
Shake well before use. Fill the spray tank half full with water. Add BLACKJAK at the recommended rate, as well as the leaf fertilizers and the plant protection products to be used. Agitate the solution when topping off the tank with water – and then spray.
