Q. When creating liquid Blends for Tobacco, we need to formulate based on a ratio of one part Aqua Ammonia to three parts Phosphate.
A. To accomplish this ratio in Agvance Blending, set up the Nitrogen form breakdown on the Blend Setup tab of the product to fulfill the 33.34% Nitrogen needed to satisfy the request. This product may not be the cheapest product available; therefore, through Least Cost Formulation, the remaining Nitrogen request will be fulfilled by the cheapest Nitrogen source.
In this example, a one ton request of 4-4-10-1S-2Cl will be used. Aqua Ammonia is the Nitrogen product that will fulfill the one part Nitrogen for three parts of Phosphorus. Edit the product, and navigate to the Blend Setup tab. In the Nutrient Contributor Information area, Aqua Ammonia is set up at 24.6 units of Nitrogen. Select the Details button. On the N tab, the Nitrogen form is set up as 100% Ammoniacal Nitrogen.
When adding a Blend Ticket, in the Formulate By area, select Guaranteed Analysis. Enter the request for the Blend, such as 4-4-10-1S-2Cl, and then double click on N. In the Set Nutrient Source Constraints window, set the % Ammoniacal Nitrogen to >=, and enter ‘33.34.’ Choose OK.
Note: The following is the formula used to arrive at the value entered for % Ammoniacal Nitrogen in this example.
4 (The Phosphorus request in the Blend) X 33.34% (1/3 of the Phosphorus request to be fulfilled by Aqua Ammonia) = 1.3336
1.3336 / 4N (The Nitrogen request in this example) = 33.34%.
Select the Formulate button, and review the results.
Note: This N request is finished by other sources with Nitrogen contributors that are cheaper than the Aqua Ammonia.
