To ensure a constant protection by windbreaks, hedgerows
should not be completely harvested. Within short rotation
alley cropping systems it is practical to plant hedgerows
consisting of four or more tree rows. This allows for the cutting
of only the half of the tree rows at each harvest and thus
ensures a permanent wind protection. However, if hedgerows
are planted in an east west direction, then the shadow effect of
unharvested tree rows may result in growth depressions of the
trees resprouted. In such cases, it is advisable to harvest each
second hedgerow completely. In order to ensure that the wind
protection effect is still high, while shorter distances between
hedgerows can be used, unless this is incompatible with the
available machines.
