Research Project: **Location:
                            Application Technology Research** Project Number: 5082-21000-001-067-S
                        
                        Project Type: Non-Assistance Cooperative Agreement Start Date: Apr 18, 2022
                        
                        End Date: Oct 17, 2023 **Objective:**
                        
                        The objective is to develop new container potting substrates derived partly from wood-based biochar, and determine the impacts of these potting substrates on plant growth and infestation from fungus gnats. **Approach:**
                        
                        Three different textures of biochar, either amended with wood vinegar or not (to stabilize pH) will be mixed with varying ratios of peat moss, pine bark, and coir.  The chemical and physical properties of the substrates will be determined.  Long-term stability of the substrate mixtures will be determined with an accelerated incubation study.  Phytotoxicity, seed germination, and plant growth studies will be conducted to document crop response and correlation to measured chemical and physical properties.
