Towards improving soil biology and organic matter for urban tree health

2007 | Bryant Scharenbroch and Gary Watson, The Morton Arboretum
Examine biochemistry in urban soils, determine the effectiveness of mulching, compost teas, and fertilization to improve soil organic matter and soil biology. Particular focus will be placed on compost teas as a mulch alternative in situations where surface mulching is not possible.

Study Conclusion

Compost topdressings and wood-chip mulches are effective and cost-efficient methods for improving soil quality and stimulating tree growth in compacted urban landscape soils.
