Business case: tank and injection system design for the agricultural industry

Engrais, Servitank

Adding additives to fertilizer recipes helps adjust the product to various farmlands, based on the nutritional deficiencies found in the soil.

This step (addition of additives) adds to the agricultural supply chain, which in turn reduces the number of possible deliveries. Most of the time, adding additives is done manually for each fertilizer, which also significantly increases delivery time. These two issues raise the following question: how can we offer a personalized fertilizer to each customer without increasing delivery time and reducing the number of deliveries?

Servitank solutions*

Servitank supports blends that inject additives directly into an automated pipeline controlled by programmable logic controllers. The automation of this process makes the manufacturing of tailored fertilizers simple, flexible, and fast.

Reservoirs, pumps, and pipes have been installed and adapted to the process of adding additives directly to the Servitank terminal for agribusiness customers.

Customer results and impacts

Customers using this tailored solution for the agricultural industry have highlighted several positive impacts:

  • Green logistics chain: simplified logistics (200 km shorter route) and the reduction of greenhouse gases and transportation costs.
  • Fast and efficient delivery times make it possible to ship across the province and to Ontario (at the beginning and end of the season).

* Of course, proposed solutions include health, safety, and environment aspects [training, procedures, risk/environmental analysis, and emergency plans].

The benefits of a second application of dust suppressant

Abat-poussière, dust

Did you know that calcium chloride absorbs moisture from the air? It is thanks to this absorption, also called hygroscopic effect, that the dust remains trapped on the ground.

That being said, the effectiveness of a dust suppressant depends on the humidity present in the air, which is why a second application may be necessary during a dry, hot summer.

As mentioned in standard 6322-22 on the “Application of dust suppressants on granular material bearing surfaces”, Transport Québec recommends “to make a second application […]”. This recommendation supports the principle that a second application has a cumulative effect:

  • The first application (in sufficient concentration) captures more moisture.
  • The second application reactivates the first one.
  • The second application extends the yield (in late fall).
  • With a second application, the residual is more highly concentrated when leveling in the following spring.
  • The residual is reactivated by the first application of the following season!

Standard 6322-22 also states that the application rate of the second spreading is usually half what is used for the initial application.

Example of quantity required during a second spreading:

1st application: 3,600 liters/km for liquid or two tons/km for flakes*.

2nd application: 1,800 liters/km for liquid or one ton/km for flakes*.


* Recommended quantity for a four-meter-wide road, based on the recommended application rate of 0.9 to 1.2 liters per m2.

It is interesting to note that only a small amount is required to significantly prolong the effectiveness of the product.
