Technical Report
What are the opportunities to reduce variability in apple tree productivity through targeted (sub-block) water and nutrient application?
Most of New Zealand’s apple production occurs on soils which have formed from alluvial (river movement) deposits. These soils range from clays to sand, to…

Measuring real time nitrate leaching from a Hawkes Bay onion Field
The primary objective of this project was to prove that successful real time ‘in situ’ nitrate measuring was possible using a nitrate sensor and that…
