Effect of Compost Extract on Qualitative Soil Health and Carrot Yield
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.
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.
