land application system on land used for food crops?

Are there any guidelines or requirements setting out when you can or cant install a land application system on land that is used for food crops. i.e. within established kiwifruit orchard or fruit tree orchard?

TP58 make references in 7.7.2.2 to "Irrigation of fruit trees and crop plants where there is no direct contact with the crop" being acceptable, but that is under "re-use"


Thanks in advance
