NACHURS K-flex® MAX

Powered by NACHURS® Bio-K® technology, NACHURS K-flex MAX offers versatility with multiple application options and is compatible with 10-34-0 and UAN. It provides two very critical plant nutrients - Potassium and Sulfur; typically missing from these base fertilizer products. 

NACHURS K-flex MAX

NACHURS K-flex MAX fertilizer is designed to be blended with various other fertilizers to provide important nutrient needed to grow high-yielding crops. It also contains humic acid which provides faster seed germination, increased root growth and nutrient uptake, and provides improved soil porosity and exchange capacity. NACHURS K-flex MAX can be mixed with APP (i.e. 10-34-0) and/or UAN solutions to provide two very critical plant nutrients - Potassium and Sulfur; typically missing from these base fertilizer products. NACHURS K-flex MAX fertilizer added to APP creates a starter blend that can be used as a foundation for planting in cold soils, especially in minimum or no-till environments. It can be blended with UAN solutions to create a strip-till/sidedress/basal fertilizer that provides extra potassium and sulfur, as well as humic acid, to help improve nitrogen use efficiency.

PATENTED POTASSIUM ACETATE TECHNOLOGY

NACHURS Bio-K is a premium source of potassium fertilizer combined with a natural plant metabolite creating the most effective and efficient source of potassium. Using Bio-K technology results in quicker germination, improved root development, and an elevated abiotic stress tolerance; this leads to better plant establishment, more vigorous growth, and higher yields.

What makes Bio-K unique is in the origination of its organic-based carrier (anion), the acetate molecule. Acetate is a natural plant metabolite that has many important functions within the plant as well as in the symbiotic relationship between plant roots and soil microbes/mycorrhizal fungi.

Since the carrier portion of Bio-K is a natural plant metabolite, it is more rapidly and readily taken up by plants, which in turn leads to increased potassium use efficiency and higher productivity.

Always the innovator, never the imitator. ®

“We started using NACHURS 0-0-19 [NACHURS K-flex] this spring at a rate of 1 gallon per acre. Using the 0-0-19 I noticed a much faster green up response at the early lawn applications. I also noticed we seemed to have better color as well.”

“With imPulse, my customers not only saw more even emergence, but the crop health aspect was phenomenal. Comparing imPulse to where we had a planter hiccup was a night and day difference. The plant was 1 to 2 leaf stages ahead of the untreated, and the root proliferation was excellent. I will definitely be recommending imPulse to all my growers next year to have in their in-furrow programs.”

“We have used NACHURS in-furrow on our corn the last two years. When comparing side by side strips we’ve done the NACHURS stand has consistently been 1300-1500 more plants per acre when we’ve done stand counts. The other starter was a competitor’s 6-24-6 w/zinc. When doing these comparisons, I’ve noticed the NACHURS doesn’t leave a corrosive sticky film on everything it touches. We are currently with our NACHURS team to come up with a nutrient rich plan for next year.”

“We used the potassium acetate in-furrow and in layby bonded applications, also used K-flex in a blend with herbicide, and additional fertilizer through the spray rig. This product mixes well with all applications. Plant response was very good in terms of early growth to the bloom stage on dry beans, and was great on corn to V-5. This next season subsequent use of K-flex w/Zn will also be applied foliar as midseason application.”
