THE PRODUCTTHE TECHNOLOGY THE SCIENCE

nitrogen potassium sulfur

Higher crop yields, along with applications of potassium that haven’t kept up with the crop removal pace, have left many acres in decline of available potassium. Similar decreases can be found with Sulfur since dry fertilizer manufacturing practices as well as Clean Air measures have limited or removed incidental sulfur from being part of the residual nutrient supply.

NACHURS K-fuse, by addition of potassium and sulfur to high nitrogen fertility programs will address known deficiencies as well as improve nitrogen use efficiency. NACHURS K-fuse is designed to be blended with various fertilizer products to provide additional potassium and sulfur needed to promote high yielding crops. Primarily, NACHURS K-fuse should be blended with UAN solutions for sidedress and/or fertigation application to provide two very critical elements: potassium and sulfur. It can also be mixed with APP and UAN for 2x2 and/or strip-till application to provide a more balanced nutrient program. NACHURS K-fuse contains a proprietary additive which is designed to be blended with various fertilizer products to provide additional potassium and sulfur needed to promote high yielding crops. Up to 32% more potassium and 93% more sulfur can be applied per acre versus potassium thiosulfate when blended with UAN.

Give your crop the “UAN potassium specialist” to help achieve your nutrient goals: NACHURS K-fuse.

fertigation strip-till/side-dress

General Rates:Soil applied: 1-3 gal/ac Foliar applied: contact a repFertigation: 1-3 gal/ac

NACHURS K-fuse is to be blended with UAN solutions at the following ratios:

• 3 gal 28% UAN:1 gal NACHURS K-fuse• 4 gal 32% UAN:1 gal NACHURS K-fuse

Always follow mixing recommendations to limit risk potential of forming low solubility potassium nitrate compounds. NACHURS K-fuse should not come in close proximity to the seed under any circumstance (i.e. in-furrow placement).

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.

FEATURES:

Acetate is a natural organic acid and plant metabolite Two influencers (potassium fertility and biostimulant) in a single product Very low salt index Excellent compatibility with other fertilizers

BENEFITS:

Recognized by plants as a natural form of potassium playing an important function within the plant, forming many compounds necessary for increased productivity

The preferred source of potassium for plant uptake due to the acetate carrier molecule – more efficient and readily absorbed by the plant

Plant and seed safe – will not burn at recommended rates Blending and tank mixing flexibility

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 of plant roots, soil microbes, and mycorrhizal fungi.

P<.0001*Application rate: 4 gal a.i./acre (93.5% K-salt + 6.5% PGPR) = 1.5 ul a.i./90 g soil

*Soil Preparation and Inoculation:A 90 g aliquot of soil will be weighed in 100 ml beaker and then placed in a 1 L glass jar. The jar will then be autoclaved for 3 hours on two consecutive days in order to sterilize the soil. A 50 ml solution will be prepared for each treatment as follows: 93.5% K-salt (46.75 ml) plus 6.5% PGPR (3.25 ml). Solutions will be prepared two days prior to inoculating soil. Treatments (1.5 ul aliquot) will then be added to soil with sufficient carrier (28 ml DI H2O) to bring the soil moisture to approximately 50% water filled pore space. Approximately 10 ml DI H2O will be added to the bottom of the jar and lids sealed tightly so that soil moisture is maintained during incubation. The 72 microcosms will be placed in a temperature controlled incubator at 30°C. Microcosms will be removed from the incubator 7d after treatment initiation and prepared for fumigation and extraction with 0.5 M K2SO4. The 90 g soil sample will be divided equally into three 30 g subsamples and each placed in 50 ml beakers. Two of the samples will be fumigated and third will not (non-fumigated samples). Samples to be fumigated will be put into a vacuum dessicator along with 50 ml beaker containing ethanol-free chloroform (20 ml) and boiling chips. The dessicator will be evacuated and vented six times, but on the sixth cycle it will not be vented. After three days, the vacuum will be released and the chloroform removed.

It’s not so much about the use of potassium (as we agree it is an important farming practice), but rather the use of an efficient, available, and soluble potassium source to drive nutrient stewardship, sustainability, and yield.

*Contact a NACHURS representative for specific recommendations. It is always recommended that a jar test be done when adding to other

fertilizer or chemicals. Always read and follow the pesticide labels when considering tank mixing pesticides with fertilizer products.
