Fertigation is believed to minimise the risk of NO3-N leaching through careful application of water and nitrogen (N) fertiliser according to crop requirements at any growth phase and fertiliser localization close to roots (Agostini et al., 2010). However, the impact of the fertigation technique on water and N dynamics in the soil may also depend on fertigation and irrigation frequency (Zotarelli et al., 2009). The aim of this experiment was to assess the effect of fertigation-irrigation frequency on crop N uptake and potential N leaching.
High fertigation frequency decreases potential nitrogen leaching in processing tomato grown with high nitrogen and water supply.

Abstract
Fertigation is believed to minimise the risk of NO3-N leaching through careful application of water and nitrogen (N) fertiliser according to crop requirements at any growth phase and fertiliser localization close to roots (Agostini et al., 2010). However, the impact of the fertigation technique on water and N dynamics in the soil may also depend on fertigation and irrigation frequency (Zotarelli et al., 2009). The aim of this experiment was to assess the effect of fertigation-irrigation frequency on crop N uptake and potential N leaching.File in questo prodotto:
