The Manure Tracker app allows you to count and record manure applications on a field by field basis. It uses the GPS already in your phone. It was developed through UW Dairy Innovation Hub funds. Division of Extension Specialist Chris Clark of Northeast Wisconsin has the details. She says this free smartphone app can help custom operators, farmers, and nutrient management plan writers. Each manure application is counted on your smartphone and details can be sent as a .csv file to an email address for further record management and safekeeping.
