Fit roots for plant health Technical bulletin 2020 EN
High root temperature increases
water uptake; low root temperature slows down
water uptake.
Although technical options to influence root
temperature are often [...] related to the
plant’s energy balance.
The temperature of the irrigation water can
influence the root zone temperature and thus the
uptake of water and nutrients [...] water, particularly in the
morning, can lower the temperature of the stem
base. If the temperature of the stem base drops
below the dewpoint, moisture
