For many years, work has been going on in an attempt to improve the irrigation methods and techniques for growing avocados. This is because these factors will impact on the volume and frequency of irrigation and fertiliser required. Learn more. If you do not have an acceptable delivery uniformity of at least 85%, within a block, you will be delivering excessively different volumes of water to different trees within the block. There are protocols regarding leaf sampling. Growers in hot areas use overhead sprinklers (assuming good quality water is available) for evaporative cooling to preserve the crop during heat waves.

The mainline supplies water from the … 12. The size of the mini-sprinklers will be determined by the tree spacing — a 7 x 4m tree spacing would be best served by a mini-sprinkler with a diameter throw of about 4m, an 8 x 5m spacing a 5m diameter throw.
