SmartSlurry, a free app developed by SEGES Innovation, makes it easy to digitize slurry analyses, calculate precise fertilization values, and enables farmers to register and view analyses, and thereby monitor nutrient levels in their slurry tanks, including nitrogen, phosphorus, potassium, dry matter, and pH. Slurry analyses can be registered manually by entering the values into the app or automatically by scanning the QR code on the slurry analysis order. However, the automatic registration only works if the farmer is also using the registration app FarmTracking. The data registered in SmartSlurry are automatically synchronized with the fertilizer planning tool MarkOnline. Additionally, users can track activities related to the slurry tanks, such as agitation, transport, establishment of crust, or if the tank is empty. The app also includes an inspection function, allowing farmers to take notes and add pictures from tank inspections, and keep track of when the next inspection is due. This provides farmers with an easy-to-use tool to monitor slurry analyses, nutrient contents, and tank inspections for each respective slurry tank on the farm, all in one place.
