The City to Farm Composting Project (C2F) is looking for more farms to participate in a Terra Preta Research Project which builds topsoil using bokashi-fermented food scraps and biochar. C2F sits at the intersection of zero waste, regenerative agriculture and climate change mitigation.

The current research site is in Waitoki on heavy clay, ex-pasture soil where over 150 tonnes of local urban food scraps have been diverted from landfill. They are applied in compost swales to replenish soil nutrients to grow heavy feeding bananas. Soil high in organic carbon buffers against the extreme weather events of climate change making it easier for water to penetrate and enabling storage it in times of drought. Changing heavy clay into higher quality soil enables more growing options for those wishing to diversify cropping. Growing food locally is also a climate mitigation strategy.

New sites will need to be in the Waitoki/Wainui area.  To find out if your property is suitable to be part of this project of national significance, please attend one of our presentations or email info@citytofarm.co.nz
