Air Seeders: The Ideal Humic Acid Delivery Tool

One of the hottest topics of conversation this Spring between growers and our sales team has been the application of our Humic DG through an air seeder. Many growers are having success with Humic DG in both in-furrow or sideband applications.

But why keep all of this knowledge to ourselves? I wanted to take a few moments to share some of the thoughts behind air seeder applications of Humic DG on small grain, soybean and oil seed production.

Why an Air Seeder?
Air seeders (or air drills) have been used in small grain and oil seed production since the early 1980’s, and have been popular with medium and large producers. More recently, they have been modified for use with a wider range of crops, including vegetables and corn silage planting.

The beauty of an air seeder is in the precision it commands with the placement of nutrients (including humates) and seeds. The more precise the placement of humate in relation to the seed, the greater the opportunity to maximize the benefits of humic acid; benefits that shouldn’t be ignored — improved water retention and nutrient uptake, and greater root development.

These benefits, coupled with the technology and superior handling characteristics Humic DG provides, make an “air seeder + Humic DG” application the ideal way to ensure that both soil AND seed are receiving the humic acid they need.

What Makes Humic DG Ideal for an Air Seeder?
Let’s agree that the best way to incorporate humates into a planting scheme is with an in-furrow or a sideband application. With that being said, granular humates have historically caused headaches in this regard, as their less than ideal handling characteristics have made them difficult to manage in seeding or fertilizer blending operations.

Enter Humic DG. With its engineered, spherical particles, growers tell us that Humic DG accentuates all of the major advantages of an air seeder; that the free-flowing homogeneous product allows for the precision placement and maximum uptake of humic acid.

The DG Advantage
Featuring our patented Dispersing Granule (DG) Technology, Humic DG represents a unique, high-tech humic solution; one that’s taylor made for air seeder applications. On contact with soil moisture, each DG granule releases thousands of sub-particles into the immediate vicinity of the seed – taking precision humic acid delivery to the next level. Also found in Black Gypsum DG (humic acid + natural gyspum), DG technology is the most efficient way to make all three humic substances (fulvic acids, humic acids and humins) quickly available to both soil and seed.

Are There Cost Savings Involved?
I’ll let the numbers speak for themselves. Air seeders, in both sideband and in-furrow applications of Humic DG, allow the grower to maximize humic acid delivery rates at an economical input cost. The majority of the growers we’ve spoken with are utilizing air seeders to apply Humic DG at a rate of 5-10 lbs. per acre (in-furrow). At this rate, Humic DG is delivering up to 6x the amount of humic acid, compared to one gallon of 12% liquid humic acid, at a similar cost/acre.

Is There Still Time in 2014?
If you’re already utilizing air seeder technology in your operation, consider Humic DG and Black Gypsum DG as your humic acid sources. The precision of an air seeder + the efficiency of DG technology means big advantages for you AND your plants.

While yes, the year is almost halfway through, there is still time to capture the benefits of Humic DG & Black Gypsum DG with applications in 2014. Double crop soybeans and small grain plantings will benefit from a late summer or a fall application, as both products can be applied directly, or blended with a granular, starter fertilizer.
