description
The Nevada Division of Forestry (NDF), in collaboration with the USDA Forest Service and the Desert Research Institute, has begun assessing biochar as a potential soil amendment for enhancing growth and survival of urban trees. Utilizing a low-value forest product as a feedstock, an NDF-funded pilot study demonstrated improved soil moisture, fertilizer retention, plant growth and carbon sequestration in biochar-enhanced soils. NDF is working to optimize the production process and application rates, as well as expand the use of biochar in nursery soil mixes and in urban tree wells throughout the state.
