RESEARCH PROTOCOL

Compost extract (compost steeped in water, then sieved) is a popular soil amendment to increase beneficial biota and increase yields. Two treatment levels of compost extract were applied to carrots on two farms to determine impact on yield and soil microbes.

KEY FINDINGS:
• Compost extract did not impact carrot
yield at either farm.
• Compost extract did not impact soil
biota (as measured by a Qualitative
Soil Analysis).
• Carrots from the High compost extract
treatment at Jason Jones farm were
significantly longer than untreated
plots.
• Carrots from the plots treated with
compost extract at Siobhan Danreis’
farm showed significantly higher
degrees Brix.
