Polymer coated Urea 
Crop Segments
Controlled release fertiliser providing more efficient nutrient use.
Quality & Handling
Granules are white with a size specification of ≥ 90% at 2.0 mm – 4.75 mm.
Ideal for blending due to its hard coating and granule size. Fully blendable with all conventional fertilisers.

1. Features and benefits

  • Potential increased or equal yield at lower rates due to improved efficiency.
  • Seed safe, which means significantly higher rates of N can be in contact with seed.
  • Saving in labour costs because fewer applications required.
  • Fully blendable with all conventional fertilisers.
  • Reduced environmental impact.

Agromaster uses a new and advanced polymer coating to dictate the release of N into the soil. This product provides nitrogen over a set time that is defined and predictable, giving a grower peace of mind knowing that their crops will have access to nitrogen at critical growth stages.

Agromaster is designed to minimise nutrient release for the first 30 days after application in order to increase the efficiency of nitrogen supply. This curb of nitrogen supply within the first month guarantees greater nutrient efficiency by allowing growers to provide initial plant requirements of nitrogen through an alternative, cheaper source (urea) and banking the added controlled release source of nitrogen to be utilised later on when the crop requires it.


2. Manufacture

Agromaster’s coating technology is designed with a nitrogen core surrounded by a polymer coating that controls the release of nutrients to the soil.

3. Uses

Agromaster can be used effectively for all crops. Because the product can be blended, a portion of the current N can be converted to Agromaster.

4. Storage and handling

  • Can be stored for extended periods of time due to the coating hence fewer hygroscopic issues. The product is high quality with low dust. It is extremely free flowing through equipment and has less risk of caking.

5. Restrictions

  • Do not store in bulk piles on wet floors as moisture triggers release mechanism.
