Zakah on palm trees planted at home and on Al-Barhy palm-trees

Q 1: A number of date palm trees are planted in our houses in Al-Qasim district. The amount of dates exceeds the prescribed Nisab (the minimum amount on which Zakah is due). While in some houses, these trees are irrigated by drinking water, in other houses they are irrigated by means of machines. An amount of these dates is eaten, another distributed to relatives and a third stored. No Zakah is paid for these dates. Please tell us whether Zakah is due or not.

A: If the reality is as you mentioned, Zakah is due at a rate of half the tenth of the dates (5%) because the trees are irrigated by means of a machine.
