Where, in the opinion of a Board, the cultivation in the cantonment of any description of crop or the use therein of any kind of manure or the irrigation of any land therein in any specified manner is likely to be injurious to the health of persons dwelling in the neighbourhood, the Board may, by public notice, prohibit such cultivation, use or irrigation after such date as may be specified in the notice, or may, by a like notice, direct that it shall be carried out subject to such conditions as the Board thinks fit:
     Provided that if, when a notice is issued under this section, any land to which it relates has been lawfully prepared for cultivation or any crop is sown therein or is standing there on, the Board shall, if it directs that the notice is to take effect on a date earlier than that by which the crop would ordinarily be sown or reaped, as the case may be, make compensation to all persons interested in the land or crop for the loss, if any, incurred by them respectively by reason of compliance with the notice.
