You already know soil chemistry ties up P and K. You’ve seen it on your own soil tests. The question isn’t whether it happens. It’s what to do about it before your fall pass goes out.
This post gets into what Microcoat Ultra actually is, how NET Technology works underground once the granules hit the field, and what growers are seeing on their acres this fall. If you’re weighing whether to add a treatment to your dry fertilizer order, this is the tech side of that decision.
What Microcoat Ultra Actually Is
Microcoat Ultra is a dry fertilizer additive. It gets impregnated onto the granules of your dry P and K, so every granule of DAP, MAP and/or Potash carries the coating on it before it reaches the field.
The coating is not just a shell. It carries three separate proprietary technologies plus a micronutrient package. When those coated granules hit the soil and start to break down, each technology has a specific job.
Three things to know about how the product handles in your operation:
- It works with your existing fertilizer sources, so you don’t change what you’re buying; you change what’s on it.
- It fits into your existing application pass, so no new equipment and no new trip across the field.
- It’s compatible with the dry fertilizer blends most retailers already run.
NET Technology, Explained
NET stands for Nutrient Efficiency Technology. It’s the reason Microcoat Ultra exists as a product, and it’s what does the real work in your fall P and K program.
Here’s the mechanism. When phosphorus and potassium sit in the soil, they’re constantly reacting with whatever else is in that soil. In alkaline ground, phosphorus reacts with calcium. In acidic ground, it reacts with aluminum and iron. Those reactions form compounds that plants can’t take up. The nutrients are still there. Your soil test still detects them. But they’re not in a form roots can pull in.
NET is an enzyme package. Enzymes are biological compounds that speed up chemical reactions, and in this case, they speed up the reactions that break those tie-up bonds apart. When NET-coated fertilizer meets soil moisture, the enzymes activate. They go to work on the compounds around each granule, splitting apart the calcium phosphate bonds in alkaline soils and the aluminum phosphate and iron phosphate bonds in acidic soils. What comes out the other side is phosphorus and potassium in the ionic forms plants actually absorb through their roots.
The important part is that NET keeps working. It’s not a one-time reaction. As long as the coated fertilizer is in the soil profile, NET continues to influence the chemistry immediately around each granule. That’s how you get sustained availability instead of a short spike followed by tie-up.
What Else Is In the Coating
NET is the lead technology, but Microcoat Ultra carries two other proprietary technologies and a micronutrient package. Each one has its own role once the fertilizer is in the plant system.
nCeption Technology
nCeption is a carbon-based delivery system. It helps root cells recognize and absorb the nutrients NET has freed up. Think of NET as unlocking the nutrients in the soil, and nCeption as helping the plant actually take them in through the root wall.
NTake Technology
NTake works inside the plant. Once nutrients are absorbed through the roots, they have to move to the parts of the plant that use them. NTake maximizes that movement, getting essential elements to the growth points that drive yield.
Built-In Micronutrient Package
Microcoat Ultra also carries a package of zinc, boron, and other micronutrients your crop needs early in the season. Instead of a separate micro application, these are distributed evenly across every granule of your P and K. That means every acre gets the same micronutrient coverage, and you don’t have to plan or pay for a separate pass.
What Growers Are Seeing
Trial data on Microcoat Ultra continues to build across geographies and soil types. A study by an independent research firm in Whitewater, Wisconsin, showed corn treated with Microcoat Ultra-coated fertilizer outperformed the grower-standard untreated fertilizer by 9.76 bushels per acre.
More trial data, by region and soil type, is available through your AgXplore rep. Ask specifically for results on soils similar to yours, since availability behavior varies with pH and CEC, and the response varies with it.
What This Means for Your Fall Program
If you’re planning your fall dry P and K application, adding Microcoat Ultra changes what comes out of that pass without changing the pass itself. You order your normal fertilizer. Your retailer coats it. Your applicator spreads it. What’s different is that each granule leaves the spreader carrying enzymes that will work on your soil chemistry from the day it hits the ground through the spring, keeping more of what you spread available for next year’s crop.
The tech is doing something specific. NET keeps P and K available in the soil. nCeption helps roots absorb it. NTake moves it through the plant. Micronutrients ride along on every granule. Four things happening at once, from one coating, in one application pass.
Talk to your AgXplore rep or your local dealer about adding Microcoat Ultra to your fall order. Book early, because coating capacity fills up as fall applications ramp.
