Abstract/Contents:"Presents a study conducted by Iowa State University "to explore the use of biochar as a sand-based turfgrass root-zone amendment." Details the materials and methods used during the study, stating that "for treatment mixtures, we used calcareous sand with pH [potential Hydrogen] of 8.2 that is commonly used for sand-based root-zone construction. Water-retention studies were conducted using pressure chambers. Each treatment mixture was analyzed for nutrient content using common soil test laboratory procedures." Reports that biochar mixed with sand may increase water retention and holding capacity and decrease the infiltration rate. Continues that "increased levels of phosphorus, potassium and sodium were observed in extracted pore water as concentrations of biochar increased." Concludes that "these data indicate that sand and biochar root zones have the potential to reduce nitrogen losses from the profile, which may play a role in turf fertility practices. Therefore, these results should be further evaluated."
