In this episode of Spudchat, we welcome back Dr. Judith Nyiraneza from AAFC Charlottetown to talk about manure and other soil amendments in potato rotation, including some of the work that she and her team have been doing through ACS Living Labs and other projects. We talk about a long term rotation trial comparing the use of manure compared with different cover crops, as well as some on-farm trials using liquid manure, biochar, and willow wood chips.
