1. Reducing Nutrient Losses in Runoff from Furrow IrrigationFew studies have comprehensively examined nutrient losses in runoff from furrow-irrigated fields, but the rising cost of fertilizer and finite nature of the resource encourages further research. A 2-yr experiment measured runoff losses of sediment, particulate P and N, and dissolved NO3-N, NH4-N, K, and reactive P (DRP) from fertilized, manured, or non-amended fields. Average nutrient losses were substantial, including 15.6 lbs ac-1 yr-1 dissolved N, P, and K and 73.6 lbs ac- 1 yr-1 particulate... R. Lentz, D. Westermann, G. Lehrsch |
2. Managing Soils for CO2 Drawdown: Boon or Boondoggle?Consensus is growing that meeting the goal of a two degree or less global warming will not only require aggressive greenhouse gas emission reductions across all sectors of the global economy, but also active measures to remove CO2from the atmosphere. Among the broader suite of CO2 removal (CDR) strategies, soil C sink approaches have been deemed as being among the most ready for early deployment and having the greatest net environmental benefits. A variety of existing... K. Paustian |
