DG Technology
Dispersible Granule (DG) Technology is our patented nutrient delivery system.
With DG Technology, particles are more rapidly and efficiently broken down.
Upon contact with water, each DG granule disperses into thousands of micro particles that move through the turf canopy into the root zone. This level of dispersibility delivers precise nutrient delivery, while eliminating issues associated with runoff and nutrient loss.
Optimized Nutrition
No Mower Pickup
Following irrigation, DG products immediately begin dispersing down into the soil, eliminating mower pickup and delivering 100% of the applied nutrients right where you need them. Mower pickup of conventional granular fertilizers is reported to be as high as 15-25%.
No Particle Movement
DG products disperse quickly and completely when watered, moving directly into the soil. In a heavy rain or over-irrigation, conventional fertilizers may float and be carried off the intended application area, or be deposited in low lying areas, where they may cause damage.
No Mower Damage or Residual Shells
DG particles do not rely on a physical coating to release nutrients. Coated fertilizers (used by our competitors) are very susceptible to damage from mowers, resulting in premature nutrient release.
Improved Playing Conditions
Less Interruption of Play
The fact that products utilizing our DG Technology require less watering to disperse the nutrient granules means that you can enjoy less downtime, along with a drier and firmer playing surface.
No Sticky Residue
With DG Technology, you can enjoy a line of products that melt directly into the soil. The result is no sticky fertilizer residue, which can accumulate on shoes, balls and other equipment.
Humic Acid Precusor
How Does Humic Acid Precursor Work?
Humic acid precursor contains a soluble form of organic carbon which releases into the soil as Nutri DG and DG Pro granules disperse. Through biochemical reactions in the soil, humic acid precursor is transformed into humic and fulvic acids, which help chelate nutrients in the soil. The optimum rate of humic acid precursor is applied when Nutri DG and DG Pro are applied at label rates.

SG Technology
Our Soluble Granule (SG) Technology is a unique, highly concentrated, water soluble granule formulation.
Soluble granules are easy to use, and when combined with water or liquid fertilizer, they rapidly dissolve into a complete solution.
Soluble Granules have many advantages when compared to powders and liquids, including:
- Clean and easy to handle, as compared to powders
- Easy to mix and rapidly solubilize
- Highly concentrated, which reduces both shipping and storage costs, when compared to liquid formulations
- Eliminate the need to ship and store water
- Can be applied through a variety of application equipment including sprayers, tank mixes, fertigation, injectors, drip irrigation and other liquid applicators

Controlled Release Nitrogen
The following nitrogen sources represent our controlled release nitrogen options, each with its own set of advantages and applications.
MUtech
Four choices of MUtech (methylene urea) are each highly engineered to deliver steady, predictable nitrogen treatments, whatever your climate zone.
Proven Benefits of MUtech
- Nitrogen is released through the naturally occurring action of soil microbial activity, helping nutrient performance and soil structure
- MUtech allows consistently predictable feeding, turf color and growth
- N release rate is not altered by physical damage to particles or by dispersion
- Low salt index equals extremely low burn potential with NO fragile coating
- N release slows as temperatures rise above 90°F, rather than increasing like coated nutrition
Release Profile of MUtech
The images below illustrate the release profile of MUtech, first by component, then by week.

Poly-S
Poly-S is a polymer-coated sulfur-coated urea for controlled release nitrogen feeding.
The Advantages of Poly-S
- Developed by Scotts
- Higher sulfur level
- Favorable handling and spreading
NS-54
NS-54 is a polymer-coated sulfur-coated urea for controlled release nitrogen feeding.
The Advantages of NS-54
- Newer technology
- Higher percentage of nitrogen
- Less sulfur
Extend
Extend is polymer-coated urea that is used for controlled release nitrogen feeding.
The Advantages of Extend
- Longer Lasting
- No Sulfur
- Well suited to large turf area such as fairways and parks
LN3
LN3 is a controlled-release liquid nitrogen nutrient based on urea-triazone technology. It is a cyclic compound, not a chain, and is chemically very stable. Its microbial degradation mechanism is better than straight chain MU, making LN3 very predicatable.
Enhanced Efficiency Nitrogen Sources
The following represent our enhanced efficiency nitrogen options, each with its own set of advantages and applications.
Fortify-N
Fortify-N is a nitrogen stabilizer that contains a urease inhibitor to reduce ammonia volatilization.
The Advantages of Fortify-N
- less volatilization means more nitrogen going to work
- registered for use in all 50 states
Nutrisphere-N
NutriSphere-N is a nutrient management tool developed by SFP. It is nitrogen-related ONLY (urea) that reduces volatilization and slows down nitrification. A very economical solution, NutriSphere-N works with existing soil chemistry.
Turf Nutrition Tool (TNT)
The Turf Nutrition Tool (TNT) is a web-based platform that allows turf managers to create custom nutrition programs and model the nitrogen release of many of our most popular granular and foliar products.
This latest version of the TNT has been completely reimagined to include:
- A mobile-friendly tool usable on any device
- A dramatically-improved user experience
- The ability to create, save, and share custom turf nutrition programs
- New product listings (Contec DG® – Gen 3, Foltec® SG, HCU™ – Humic Coated Urea, etc.)

Particle Properties
The key to good fertilization and good active ingredient performance is good particles – whether they are homogenous or blended, dispersible or not dispersible. Physical properties, size and consistency are all critical.
Dispersibility
Dispersible Granule, or "DG" Technology is The Andersons' patented nutrient delivery system. With DG Technology, particles are more rapidly and efficiently broken down.
Upon contact with water, each DG granule disperses into thousands of micro particles that move through the turf canopy into the root zone. This level of dispersibility delivers precise nutrient delivery, while eliminating issues associated with runoff and nutrient loss.

Size Guide Number (SGN)
The Size Guide Number (or SGN) is the average particle diameter of the product, expressed in millimeters, then multiplied by 100.
For example, a product with an average particle size of 1.5mm will have an SGN of 150.
Uniformity Index (UI)
The Uniformity Index is the ratio between large and small particles, multiplied by 100.
For example, a product whose UI is 50 means that the average small particle is half the size of the average large particle.
