Utilization of a root pressure chamber for nutrient uptake studies

  • Hans Riekerk
Short Communication

Summary

A root pressure-chamber is described for use with decapitated plant-root systems growing in culture solution or soil to collect sap exudates for nutrient analyses. Preliminary data show rapid nitrate-to-ammonium conversions to occur, and suggest considerable internal cycling of potassium.
