The Farm Crap App


A sustainable agriculture project designed to help farmers make the most of manure and food waste. The Crap App is a smartphone app which contains 3 components; the calculator, the image library (to which you can add your own photos), and record sheets of spreading events. The calculator determines the amount of crop-available key nutrients (nitrogen, phosphorus, potassium) within the manure at different spreading rates helping you decide how much to spread in order to meet the crop requirements, and also what this looks like.

The third version of the Crap App is now in development, and due to be released late-2019. This version will include all the manures and crops from the UK RB209 documentation. The Crap App is now recommended by the UK Agriculture and Horticulture Development Board for farmers to work out how much manure to spread - this is essential for reporting the nutrients in Nitrogen Vulnerable Zones. The current available version is the Crap App Pro, which is a working prototype with limited crops/manures.

This software won the Soil Association Innovation Award 2014. Find out all about it from Claire Reigate and Becky Willson from the Duchy College presenting in style:

The Crap App was originally developed by FoAM Kernow on behalf of the SWARM Knowledge Hub, a Rural Development Programme for England (RDPE) initiative managed by Duchy College Rural Business School. The second version (The Crap App Pro) was funded by Rothampstead Research. The third version of the Crap App is funded via the Agri-tech scheme which is made possible by the European Regional Development Fund.

All your farm's data is stored on your own mobile device - the only times the app connects to the network is to send out CSV formatted data to an email address specified by you for exporting purposes, and to identify your location for mapping your fields. The app does not connect to the network in any other way, and no data is collected by FoAM Kernow, or any other partner organisation.
