Frequently Asked Questions
There have been many questions asked about Kugler KQXRN Based Foliar Fertilizers since Top Krop began representing the technology. Following are the most salient points regarding KQXRN Slow Release Technology.
Foliar plant nutrition is not new. It has been documented as early as 1844 and has been an integral part of farming since then. In a 1952 U.S. Congressional hearing, Dr. Tukey of Michigan State University in conjunction with the Atomic Energy Commission proved that Aqueous Urea as a foliar source of Nitrogen absorbed 100% into plant leaves in less than 18 hours by using attached Radioisotopes. The Urea source of Nitrogen is the basis for KQXRN technology.
KQXRN is a Slow Release 28% Nitrogen Polymeric material referred to as Polymethylene Urea Triazone, that when applied to plant leaves simply will not burn your crop. The question always arises ͞how can liquid Urea or 28% UAN not burn͟. Answer: KQXRN is different. The Polymer is a 72% Slow Release material with the remaining 28% in an oligomeric form. All of the Urea is polymerized and not available to burn the leaves. The 72% Polymer breaks down into leaf absorbable components over a 4-6-week period in the presence of UV light, hence the slow release definition. The 28% Oligomers are immediately available for plant nutrition. KQXRN sticks to the leaf and is rain fast in one hour. When delivered, it is a clear viscous liquid that contains no water, just Polymer and Oligomers.
There are approximately 3 pounds of Nitrogen per gallon of KQXRN, so how does it foliar feed so well? Answer: The most important time for application is transition between vegetative and reproductive stages during plant growth. There is a canopy at that stage and 80% gets onto the leaf, very little on the ground. Absorption occurs in the polar cuticular pores in the leaves. Cuticular pore absorption is extremely efficient, much more so that through root absorption. Other foliar products such as Fungicides and Herbicides can be mixed with KQXRN and are absorbed more efficiently through the leaf.Salts, which normally will not foliar feed, when mixed with KQXRN and its downstream products will foliar feed at the same rate as KQXRN.
KQXRN and its downstream products, KS2075, KS1022, KS1410, KQXRN 2530, and KS178C (all containing KQXRN as all or some of the Nitrogen component) are all extremely low salt index materials, should be applied at least twice during the growing season, virtually any time a pass is made over a crop field with Herbicides and Fungicides and at vegetative to reproductive transition. 1-2 gallons per acre is the recommended application rate per pass. None of the products will gum up a sprayer, none will corrode equipment, and most will overwinter (check product handling guide).
