Example
To keep in good health, olive trees need at least two full waterings to field capacity each winter. If water can be applied more regularly during winter or at other times of the year then this will be most beneficial and will result in increased crops.
Additional information
a land is considered to have reached its field capacity when it has been flooded and cannot drain any more water, after which it retains only capillary water, which is useful for plants.
