Can I mix Tnue Smartfert with other fertilisers?

Yes, because Tnue Smartfert has a protective membrane, it can be mixed with other fertilisers. We are not aware of reaction issues, however it is best to mix a small amount first to see if there could be a problem.

Does Tnue Smartfert release nutrients in the dry?

Tnue Smartfert requires soil moisture to release the nutrient. Moisture is absorbed through the membrane dissolving the fertiliser nutrients which are then released back out through the membrane. Without enough moisture for plant growth, this process cannot occur and the nutrients are not released.

Will I get a rapid response after application like I see with straight urea?

The response from Tnue Smartfert will be slower than when compared to urea. However, the results will be over 3 months compared to urea which gives a growth response on the first month following application.

How long will I see the Tnue Smartfert granules in the soil after application?

The Tnue Smartfert granules will be visible for about 90 days after application. Initially after absorbing moisture, the granule becomes opaque. 

Does Tnue Smartfert need to be worked into the soil?

Tnue Smartfert will begin releasing nutrients once it is in contact with moist soil. It does not need to be incorporated into the soil. However if it is incorporated, the soil around the Smartfert granule is less likely to dry out and the nutrient release will be more consistent.

How does Tnue Smartfert work?

Tnue Smartfert has a unique membrane that encapsulates the fertiliser granular. This membrane allows water to diffuse into the granule, dissolving the nutrients. The nutrients are liquefied and released back out through the membrane over time with osmotic pressure. It is important that adequate soil moisture is available to ensure this process occurs.

Can I damage the membrane?

Yes you can. It is important to minimise excessive abrasive handling that may damage the membrane.  Belt and bucket handling equipment should be preferred to augers. When blending, large volumes of product will provide a buffer to abrasion and damage to Tnue Smartfert's Control Release Membrane.

How long can Tnue Smartfert be stored?

Tnue Smartfert can last a long time in storage but must be kept dry. 

Can I drill Tnue Smartfert near seeds?

Yes. Tnue Smartfert's membrane restricts the release of the fertiliser salts that can cause damage to germinating seeds.  As a guide, Tnue Smartfert can generally be drilled near seed, however the rate of application, seed type and general growing conditions must be considered.

When is the best time to apply Tnue Smartfert to a crop?

Tnue Smartfert is best applied at the time of planting of a crop. The lag of a few weeks before the release of nutrients, fits well into period when the seeds are germinating and crop establishment. As the nutrient demand for the crop increases, Smartfert will be releasing nutrients to meet this demand.

What is the difference between Tnue Smartfert and SustaiN?

Tnue Smartfert is very different. Tnue Smartfert is a true Control Release urea nitrogen fertiliser using a physical membrane barrier between the nutrient and the outside environment. When the granule is moistened the membrane allows release of nutrients to the soil.

SustaiN is sprayed with urease inhibitor. It releases as urea does but may slow the microbial activities in an attempt to reduce ammonia volatilisation. Losses still occur. SustaiN is not a Control Release or Slow Release Fertiliser

Do all coatings work the same?

No, there are a variety of coatings available on fertilisers, Tnue Smartfert is a true Control Release nitrogen fertiliser with a physical membrane that controls the release of nutrient. Other fertiliser coatings are either sprayed on such as urease inhibitors or rely on the coating being broken to release the nutrient. 

 

Will a broadcast dressing of Tnue Smartfert perform effectively for Maize?

Yes, but it is important to apply the dressing as soon as possible after sowing to allow time to work. If the soil dries excessively results will be less consistent. 

 

What happens to Smartfert in heavy rain event?

The Tnue Smartfert granules will not release nitrogen more quickly. The nutrient can only diffuse through the membrane at a given speed. Provided the granule is not removed in flood water the Smartfert  will still be there to do its job!

Will Tnue Smartfert flow from silos?

Yes Tnue Smartfert will flow from the silo, however avoid prolonged storage.
