We started the challenge by turning over a compost heap in the school grounds. We looked at the principles of effective composting, following permiculture methods. Following this exercise we researched compost organisms and how they contribute to healthy soil. The area chosen to plant vegetables was near an outlet of grey water. The learners used the Egyptian-style method of watering the vegetables by allowing the grey water to run through a soak pit and then into the furrows. They researched the pros and cons of both large commercial farming and the use of fertlizers and pesticides, as well as subsistence farming methods / crop rotation methods and the use of organic fertilizers and pesticides.
