... Soil Moisture Deficit(SMD)... is the amount of water that is required to bring a soil back to field capacity once some of the available water has been used up. Irrigation typically takes place when a predetermined SMD has been reached. This SMD may typically be 30-70% or so of the available water figure. Example :-If field capacity is 22 mm, and the available water capacity is 14 mm(this means that there is 8 mm of water which is unavailable to the plant!), then you may decide to irrigate when the SMD has reached within the range 4 mm-10 mm(i. e. between 30% and 70% of 14 mm) : If you wait until there is a SMD of 30%, there will be 4 mm of available water left in the soil, in this example. The deficit is not brought back to field capacity in practice, but maybe 80-90% of it as this allows for any unforeseen rainfall that may occur. Thus, 90% of this example field capacity is 20 mm,(i. e. 90/100 x 22 mm).  2, fiche 1, Anglais, - soil%20moisture%20deficit
