Apple fruitlet 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.
Sampling time is important. Send fruitlets as early as possible, but not so early as to be too small. Fruitlets should ideally be between 30-50g in weight, though this will vary with variety. Select 20 trees along the sampling path, as for leaf analysis. Take one fruitlet from each of the north, south, east and west sides, to give 4 fruitlets per tree. Mix the fruitlets thoroughly, and take a sub-sample of 30-50 at random. Label.
Our fruitlet analysis database is a unique system that allows a probability of deficiency to be calculated by the Megalab system from early season sampling. This gives plenty of time for nutritional applications to enhance or insure levels at harvest for quality fruit and storage.
