Apple fruit sampling and analysis
The reliability of analytical results and recommendations depends, ultimately on the sampling accuracy. The 3 stages in sampling are key, taking a representative sample, correct packing and immediate despatch to lab and supplying all the necessary background information.
A representative sampling path is required across the field. The W-pattern is adaptable to most shaped fields.
Samples should be taken within a fortnight before harvest. Parts of orchards which are known to produce fruit of different storage quality should be sampled separately. Select 20 trees along the sampling path. Take one undamaged average-sized apple from each tree. If the first apple is taken from the north side, take one from the next tree on the east, then from the south and so on. Send all 20 apples for analysis. Label.
