Suspension-Type Blends

Method 1: When the Formulate to a given Salt Out Temp checkbox is selected, the program will add water (if needed) to the blend to attain the salt out temperature manually entered by the user under the Advanced Setup button on the Product Set. When using this option, the Suspension Blend Target % field should be set to 999 so the program does not try to fulfill both the salt out temperature and the suspension percentage, which could be mutually exclusive result sets. 


After clicking OK with the setting shown above, the message below appears. This is referring to the System setting shown.


These systems use different calculation models for the various combinations of ingredients. It is important to select the system that best matches your operation.

  • No Poly UAN - For solutions that contain Urea Ammonium Nitrate (UAN) solution and no ammonium polyphosphate solution.
  • 55% Poly UAN - For solutions that use standard quality polyphosphate solution and UAN solution as their primary ingredients.
  • 70% Poly UAN - For solutions that use higher quality polyphosphate solution with UAN solution as their primary ingredients.
  • No Poly Urea - For solutions that use Urea solutions and no ammonium polyphosphate solution.
  • 55% Poly Urea - For solutions that use standard quality polyphosphate and Urea solution as their primary ingredients.
  • Base Grade - This is a product that can be pre-loaded. This inventory item must be listed in the Product Set and have the percentage filled out in order to preload. In order for this to show up on the Field Plan, there must be a % of Base to Preload figure other than zero. This product will be listed at the top of the Blend Ticket (just under water if water is also preloaded) regardless of its blend order status in the list of products.

Method 2: Set a Suspension Blend Target % and uncheck the option to Formulate to a given Salt Out Temp. This method attempts to formulate the N-P-K elements so the sum of the product analysis equals the percent entered by the user. 


ACID - Our data model uses information from the Advanced Setup window, the guaranteed analysis, and the fact that the blend set is a suspension-type blend to return the salt out temperature. When the blend is formulated so that the mix will not salt out under any normal conditions that would be encountered in an agricultural application environment, the program returns a salt out temp of ACID.

Factors Affecting the Calculated Salt Out Temperature

  1. Increasing the quantity of water in the Product Set and decreasing the quantity of the fertilizer products will usually decrease the salt out temperature, and can even cause the salt out temperature to become negative. 
  2. Adding different products in different quantities to the Product Set can change the salt out temperature. It may be helpful to experiment with your Product Sets to see how different changes to the Product Set can affect the salt out temperature.
