How do I create SetPoints in Nutrient Formulator?
Nutrient Formulator allows you to establish set points on given products. An example of this would be if you have a spreader that cannot accurately spread below a certain value, it has been decided not to apply more than a certain amount, etc. you can set values to respect those requirements. For those who were former Encirca users, this is very similar to entering your Applicator settings in Encirca 2.0. Set points are applied by order of operation. They are as follows:
- Select your Nutrient Recommendation layer from your Domain Tree.
- Navigate to Fertility.
- Select Nutrient Formulator.
- Click the on tab.
- Click to load your Recommendation layer.
- Now click on the tab. This will load the list of Products setup for that Operation.
- Select your Products you wish to use.
- For additional modifications to the recommendation, you can use the Minimum SetPoint, Maximum SetPoint, Switch SetPoint, Subtractor, Multiplier, and/or Rounding features.
- Ex: If your applicator isn’t reliable under 50 lbs of MAP, you will want to set your minimum setpoint at 50. That means nothing less than 50 lbs will be spread.
- Ex. If I don’t want my applicator to spread any rates over 250 lbs of MAP, I would set my maximum setpoint to 250 lbs. That means no more than 250 lbs of MAP will be applied even if the recommendations call for more than that.
- Ex. If I set the switch setpoint to 25, anywhere the recommendation calls for 24 lbs or less that rate will be set to zero. For any recommendation between 25 and 49 lbs that rate will be set to the minimum.
- Ex. If you recommendation calls for 60 lbs of DAP and your minimum is set to 50. You are accounting for another flat rate application by setting your subtractor to 40. If you subtract 40 from the 60 lbs in the recommendation, that leaves you with 20 lbs for this application.
- Ex. If you wanted to reduce your application rate in half you would enter .50 in the multiplier box.
- Ex. If your rounding option to Round Up and set my value at 50; my recommendation calls for 185 lbs of DAP, 200 lbs would actually be spread.
- Ex. If your rounding option to Round Down and set my value at 50, if my recommendation calls for 185 lbs of DAP, 150 lbs would actually be applied.
- Ex. If your rounding option to Nearest and set my value at 50; if my recommendation calls for 185 lbs of DAP, 200 lbs would actually be applied.
- Use the Minimum SetPoint if you know an applicator doesn’t spread accurately under a certain amount.
- Use the Maximum SetPoint to identify the maximum amount of a product that should be spread.
- Use the Switch SetPoint to define a threshold where anything below the specified amount will be applied as zero. This is similar to Encirca’s ‘Respect Zero’ option.
- Use the Subtractor to reduce all rates of a specified product by the amount entered.
- Use the Multiplier to enter a percentage (as a decimal) by which you want to adjust all the rates.
- Use the Rounding feature to round the application rates based on the method you select. Set the appropriate method: Nearest, Up, or Down and enter the value.
