abstract = {Irrigation in Belgian ‘Conference’ pear orchards is
often managed by soil water potential (Ψsoil) sensors. The
most widespread sensor among fruit growers in Belgium is the
Watermark sensor (Irrometer Co., USA). To gain better
insight into the use of the Watermark soil sensor for
irrigation scheduling in pear orchards the water extraction
pattern of the ‘Conference’ pear trees was acquired by a
numerical calculation of Ψsoil in three experimental plots.
A reasonable accordance between calculated and measured
Ψsoil was observed with R2 = 0.56 and RMSE = 13.4 kPa over
1320 observations. Furthermore the sensitivity of the
numerical calculation to the selected root distribution was
shown. The Ψsoil calculation with the root distribution
parameterized by site specific fine root length observations
gave satisfactory results for all plots, in contrast to
Ψsoil calculation based on other root distributions.},
