NACHURS Pura-K  ™

Powered by NACHURS ® Bio-K ® technology, NACHURS K-flex offers versatility with multiple application options and is c ompatible with 10-34-0, UAN, and liquid urea.  This product offers applications of K & S during critical growth stages to maximize yield potential.

NACHURS K-flex

There is a need for additional potassium in most fertility programs due to low soil test levels caused by higher crop yields that are removing more potassium than is being replaced. NACHURS K-flex fertilizer is designed to be blended with various fertilizer products to provide additional potassium and sulfur needed to promote high yielding crops. It can be mixed with APP (i.e. 10-34-0), UAN solutions and liquid urea solutions to build more balanced treatments and address known deficiencies. 

NACHURS K-flex fertilizer added to APP creates a more balanced 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 fertilizer that provides extra potassium and sulfur at a time when uptake of these nutrients is rapidly increasing. NACHURS K-flex fertilizer can also be blended with liquid urea to make an effective foliar fertilizer for forage crops and small grains. 

NACHURS K-flex gives growers the flexibility they need to help achieve maximum yield potential.

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.

NACHURS Agronomic Guide

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.”

Brian A. Pabst, CO
(NACHURS K-flex)
“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.”

Brock Gobrogge, CCA, IN
(NACHURS imPulse, NACHURS K-flex w/Zn)
“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.”

Dallas Hoffman, SD
(NACHURS imPulse, NACHURS K-flex w/Zn)
“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.”
