The Mid-Sask 60/40 (45.2-0-0) is exclusively available at Mid-Sask Ag Services locations.  The Mid-Sask 60/40 is a blend of urea and ESN to meet your crops nitrogen requirements.  ESN (Environmentally Smart Nitrogen) has been designed to be a controlled release N product to meet the crops demand.  As you can see from the chart showing N uptake in canola, the plant demand increases at 21 days and peaks at 65 days into the growing season.  The polymer coating on the ESN is designed to release N at 40-50 days into the growing season (when the crops demand is the highest).

How does it work?

This blend will supply early season N to get your crop off to a quick start for initial establishment.  Many crops run out of N later in the season and prematurely ripen and tend to have all N applied go into yield production and have none left for protein.  The ESN in the Mid-Sask 60/40 will allow your crops to have both yield and protein.  ESN is a polymer coated urea granule that acts as a barrier to prevent N losses.  The unique design of the ESN allows water through the coating and solubilizes the urea inside.  Once solubilized the N will remain in this form until the solution diffuses out of the coating into the soil.  During the act of diffusion the N will move from a high concentration in the capsule into the surrounding soil.  Warm temperatures and moisture will accommodate this.

 

 

 

 

 

Benefits of the Mid-Sask 60/40

• Increases yield and protein
  • ESN release matches the crop uptake.  Early in the growing season when N demand isn’t high the release of N from the polymer coating will be slow.  This means your N is less at risk from losses.  As the soil temperature and moisture content of the soil increases nitrogen will begin to be released.



• In trials conducted at the Melfort Research Farm yield benefits have been greater than 3 bu/ac when 60lbs+/ac of 100% ESN are applied vs. 100% urea.


• Saves you time
  • ESN doesn’t absorb moisture from the air so growers that have blends stored on farm can see the benefit of a free flowing product that doesn’t hang up in bins.
  • It allows you to complete all your N applications in one pass for the entire growing season.

• Crop safety
  • ESN will allow you to place more N safely in the soil with less risk of seedling burn.  The coating creates a barrier between the N and the seed so there is not a salt effect.

• ESN will protect your investment.
  • With so many concerns in the spring and the rising crop input investment you want to protect your N application.  N losses caused by leaching, volatilization, denitrification will be reduced.
  • Since the crop demand and uptake are met at the same time it means only the N that the crop will require will be taken up.
  • Marginal land can be used to the maximum potential by reducing N loss and preventing seedling damage due to high salt index in low organic matter soils.

• Blendable
  • The Mid-Sask 60/40 can be blended with all other dry fertilizer products for full crop nutrition needs.

• Low dust product

What crops can I use the blend on?

• Wheat & Winter Wheat – this blend is an excellent fit for these crops as it will allow for protein production at the end of the season.



• Canola - this crop has a high nutrient demand,  why risk putting down all the N down in an available form at the beginning of the season?



• Pasture/forages – broadcasting the Mid-Sask 60/40 will reduce the risk of rapid N volatilization.



• The Mid-Sask 60/40 is not recommended for application on malt barley  as high protein levels might be created and cause the sample to be rejected.

  Using The Mid-Sask 60/40 blend is just plain smart!
