¶ Nutrient Systems
SnapPlus offers the ability to save a collection of nutrient applications (a nutrient system) and quickly add them to a nutrient management plan. This feature is available on the nutrients page and the Nutrient Application Planner on the management page. Nutrient systems can also be accessed in templates and annual application updates.
Nutrient systems are also converted over from SnapPlus V2 plans when possible.
¶ Creating a Nutrient System from the Nutrient Systems Tab
If the user's plan has no nutrient systems, the only thing visible in the nutrient systems tab will be a toolbar with an input box and a prompt to add a name for the first nutrient system:
Once the name has been saved, a data table and features to add nutrient applications to the system become available. The +New manure and +New fertilizer buttons can be used to add applications to the nutrient system:
Unlike the NAP or the Daily Log, field specific information about applications, like the detailed breakdown of nutrients in proportion, is not available until the system is applied to a crop on a field. Some information is required before SnapPlus can save a new application into a nutrient system:
- Source: any of the manures or fertilizers available on the farm.
- Application season: when the nutrient is applied.
- Method: how the nutrient is applied
- Rate/Acre: how much, per acre of spreadable area, is applied
Also unlike the NAP, the available options for application seasons and methods will not be limited to what is possible based on the timing/tillage of a specific crop. Such issues will be considered later when using the system on actual crops.
¶ Area Type
Nutrient system applications are assigned to an area type matching applicable field restrictions. This allows nutrient systems set up to go on restricted area types (for example, a part of the field where nothing may be spread on winter). When the system is applied, if the field does not have the set restrictions in the given year, the system application will not be applied.
¶ Nitrification Inhibitors in Nutrient Systems
Some fertilizer sources can be applied with nitrification inhibitors. SnapPlus keeps a record of which of the base list of fertilizer sources can be applied with nitrification inhibitors. Any custom fertilizer source with some nitrogen can also be used with a nitrification inhibitor. This property can be applied, where possible, in the nutrient system.
¶ Applying nutrient systems to multiple fields
Nutrient systems can be added to more than one field at a time using the button labeled Use system.
