Leaf-Mold Compost Improves Health of Degraded Urban Soil

A study published in Urban Agriculture & Regional Food Systems Journal by Purdue University researchers found that leaf-mold compost can have particular benefits for degraded urban soil. The high-quality leaf-mold compost takes longer to develop than stirred compost, but researchers found that leaf mold compost promoted colonization by beneficial fungi and contributed disease suppression. Tomatoes grown in this study produced more and had less disease in soil amended with leaf-mold compost. Researchers suggest that these study results support the diversion of more urban leaf waste for compost production.
