Mulch matters! 🍅
In this Farmer-Led Trial, Markisha Parker, of Parker Family Urban Farms LLC - Parker Farms in Warren, Ohio, compared the effects of different organic mulches—🌾straw, 🌱grass clippings, and 🪵wood chips—against a bare-soil control group on slicer tomato yield and marketability. As an urban farmer with limited space, Markisha wanted to find a readily available mulch that would help with excess water on her farm and improve the overall quality of her tomatoes.
Now that he trial is complete, we've rounded up the results into this Final Report, available for free (like all our resources) on our website and at the Organic Research Hub: https://hub.ofrf.org/resource/ofrf-farmer-led-trials-comparing-mulch-types-on-an-urban-farm-in-transition
