3. Soil, Water and Nutrients Project

This project, conducted by DPI Vic, PFR NZ and TIA, seeks to increase the eco-efficient use of water and nutrients through improving soil health and by further understanding the irrigation requirements of modern high-density apple and pear orchards.

The project will:

·         Establish soil carbon status and infer trends over time

·         Determine the role of soil carbon in water and nutrient plant availability

·         Investigate management techniques to enhance soil health

·         Measure and predict evapotranspiration in netted apple orchards and high density pear orchards with varying canopies and tree structures

·         Investigate the effects of water deficits on fruit composition.
