Mixing Table

Desired N Feed Rate 1:15 1:100 1:200 E.C. Value
50 ppm 0.50 3.38 6.75 0.32
100 ppm 1.00 6.75 13.50 0.64
200 ppm 2.00 13.50 27.00 1.28

Limit of Solubility = 4.5 lbs per gallon

Important Notes:
E.C. value is the best method to determine fertilizer strength. Fertilizer appearance may vary in color due to variation in raw material size and tracer dye distribution upon the particles in the bag. In solution, color will remain consistent.

For best results, use warm water to dissolve product. Jack's fertilizers are made with 100% soluble raw materials that will form a true solution. Some raw materials are slower to dissolve than others. Keep stock tank covered to reduce light and debris inputs.

What does Jack's Professional 20-10-20 General Purpose fertilizer do for plants?

Jack's Professional 20-10-20 General Purpose fertilizer delivers a balanced N-P-K of 20-10-20 designed to support general production across propagation and all types of bedding plants. The high nitrate nitrogen level, which makes up 60% of total nitrogen, promotes green foliage and more compact growth.

What types of growing environments is Jack's Professional 20-10-20 suitable for?

Jack's Professional 20-10-20 is formulated for use on all outdoor grown plants and is suitable for both hydroponic and soil growing applications. The fertilizer is inorganic based and water soluble, making the nutrients immediately available in solution.

What micronutrients are included in Jack's Professional 20-10-20, and are they chelated?

Jack's Professional 20-10-20 includes iron, manganese, copper, and zinc, all in chelated form for reliable uptake, along with boron, magnesium, and molybdenum. These traditional micronutrient levels are built into the formula to support general production without requiring separate micronutrient supplements.

How do I mix Jack's Professional 20-10-20 to hit a target nitrogen feed rate?

The amount of Jack's Professional 20-10-20 dry fertilizer to add per gallon of water depends on your injector ratio and desired nitrogen level. For a 100 ppm N target, add 1.00 oz per gallon at a 1:15 ratio, 6.75 oz per gallon at a 1:100 ratio, or 13.50 oz per gallon at a 1:200 ratio, which produces an EC value of 0.64. Jack's recommends using warm water to dissolve the powder and keeping the stock tank covered to reduce light and debris.

Is Jack's Professional 20-10-20 OMRI certified or suitable for organic growing programs?

Jack's Professional 20-10-20 is not OMRI certified and is classified as an inorganic based fertilizer, so the product is not suitable for certified organic growing programs. Growers following conventional or hydroponic production methods will find the formula a strong fit.

Are there any safety considerations when using Jack's Professional 20-10-20 near livestock or forage crops?

Jack's Professional 20-10-20 contains molybdenum, and the manufacturer notes that applying fertilizers with molybdenum to forage crops may result in molybdenum levels in those crops that are toxic to ruminant animals. Growers raising forage for cattle, sheep, or other ruminants should take this into account before use.
