K-Builder 7-2-21, 50% MU
K-Builder provides an ideal ratio of potash to nitrogen to improve stress tolerance to traffic, drought, and winter. Featuring super-effective potassium carbonate as its K source, K-Builder supplies all nutrients in an available form for the plants’ immediate uptake, so less can be applied and there is no lag time or delay needed for product breakdown. Like all Growth Products fertilizers, K-Builder is a true solution, ideal for spray applications on turf, foliar feeding, and root injection for trees and ornamentals.
Features:
- Ideally suited for both fall and year-round applications to boost potassium levels
- Can be applied throughout the growing season on warm-season, transitional and cool-season grasses
- Compatible with fungicides, herbicides, insecticides, and most other technical products for ease of application
- Low salt index
- No special agitation needed, non-clogging, non-abrasive to equipment
- Safe, uniform source of nutrients for special turf applications
Guaranteed Analysis:

Application Rates:
Since K-Builder contains a 100% soluble form of Potassium, apply at lower rates than granular products. The same rates apply on all turf types.
To boost potassium levels, apply 250-500ml K-Builder in 8-20 litres of water per 100m2 every 21-30 days throughout the growing season.
In fall, to strengthen turf, apply 250-500ml K-Builder in 8-20 litres of water per 100m2 every 2-4 weeks for a total of 3-6 applications.
To resolve tissue or soil deficiencies, follow directions supplied with tissue or lab analysis report.
Note: When temperatures rise above 85F (29C), use a minimum of 16 litres of water per 100 m2 (4 gallons/1000sq.ft.).
K-Builder must first be diluted with water prior to mixing with other nutrients or pesticides. Dilute with water according to desired potassium rate and sprayer settings. Always perform a jar test before mixing pesticides in your tank. Apply all of the mixture in one day.
