only the highest quality N-P-K sources. K-Builder is formulated for
year-round fertilization and provides an ideal ratio of potash to

uptake, so less can be applied . There is no lag time or delay needed
for product breakdown. Since all Growth Products fertilizers and
micronutrients are true solutions, they are ideal for spray applications
for turf, foliar feeding and root injection for trees and ornamentals.
K-Builder is non-clogging and non-abrasive to equipment.
K-Builder is compatible with fungicides, herbicides and insecticides
and can be mixed and sprayed in one application.
