N-Protect®

Product Description

The science behind our coated urea product, slows down the conversion of nitrogen in urea to ammonia gas (ammonia volatilisation) which is lost to the atmosphere as a greenhouse gas. By slowing this process, N-Protect keeps more nitrogen in the soil for plant uptake, and reduces the impact on the environment.

N-Protect contains 300ppm active ingredient (NBPT) as registered with Fertmark.

Why Use N-Protect®

  • N-Protect is Ravensdown’s coated urea product.
  • N-Protect provides farmers and spreading contractors with more flexibility for nitrogen fertiliser application throughout spring, summer and autumn.
  • Studies show using the urease inhibitor nBPT can reduce volatilisation by up to 50%.

Safety Information

Caution When Mixing

Although N-Protect may be mixed with other products for immediate application, it is not compatible with the following: Superphosphate, Sulphur Super 30, Maxi sulphur super, Magnesium Oxide, Granular Ammonium Sulphate, Copper Sulphate and Cobalt Sulphate.

Flexi-N (magnesium coated Urea) can be used as a substitute when mixing with Superphosphate based products.

Important Information

  • How does N-Protect work?

    The urease inhibitor coating slows down the hydrolysis of urea by the urease enzyme naturally occurring in our soils. This in turn slows down the increase in pH around the hydrolysing urea granules. High pH around the granules leads to ammonium ions (NH4+) being converted to ammonia gas (NH3) which volatilises to the atmosphere.

  • Benefits

    Volatilisation risk is greatest when the following conditions occur:

    • High rates of N are applied in a single application (50-100kgN/ha).
    • There is a lack of soil moisture, rain or irrigation within 8 hours of application.
    • There is bare soil or little or no plant cover.
    • It is windy.
    • It is hot.

  • Application rates and advice

    N-Protect is usually spread at rates of between 40 and 300 kg/ha. Actual spreading rates will vary according to farm type, climate, productivity and soil type. Soil testing and fertiliser plans are available to ensure you use the right product at the correct rate. Call our Customer Centre for information.

    It is better to make several small to medium applications at intervals to minimise leaching losses and increase efficient use of the N applied compared with single heavy applications. N-Protect should not be mixed for any length of time with other fertilisers as problems of physical quality may result.

    Because of the high N concentration in N-Protect, it is very important to achieve an even spread. Make sure that the application equipment has been correctly calibrated and is properly used.

    Do not drill on contact with or close to seed, due to the risk of germination damage.
