Real-time detection of root zone-CO<inf>2</inf>and its potential for irrigation scheduling

© 2015 by the authors. The suitability of root zone-CO2measurements (WR-CO2) for irrigation scheduling was investigated and evaluated. The basic assumption was that plants reduce root respiration as a reaction to water deficit. A study with apple trees proved that measured WR-CO2originates in large...
