Compost in Broadacre Agriculture

This trial was designed for a demonstration and to allow 2nd year students to sample plants for biomass and to measure soil activity levels hence large plots (approx 1.2m X 5m ) of each treatment were used rather than smaller plots that could have been replicated. Unfortunately this means there is no statistical way to account for the within plot variability seen in the trial without multiple samplings. Student sampling would have produced the required number of samples however a timetable change meant students were not able to sample the trial. The trial was still used as a demonstration for students to view and discuss points related to soil microbial activity and compost addition.
