Compost is decomposed organic matter, managed to:
- grow beneficial microbes
- concentrate nutrients
- build humus
The benefits of compost as a soil amendment include:
- improved soil structure
- increased water holding capacity
- improved soil aeration
- slow-release fertility
- stimulation of plant growth.
Compost can be made in open windrows or enclosed bins; both approaches can be found on the Cannon Hort Plots.
Composting, and field applications of compost, are regular parts of the fertility program on the Cannon Hort Plots. Both are commonly covered during beginning farmer and resilient farmer trainings.
