The effect of soil type, fruit load and shaded area on ‘Hass’ avocado (Persea americana Mill.) water use and crop coefficients
‘Hass’ avocado tree water use was quantified within orchards located in the three main avocado growing regions of New Zealand, from 2016 to 2019. The three regions, the Bay of Plenty, the Whangarei District and the Aupouri Peninsula in the Far North District, differ in climate and soil type (allophanic, clay, and sandy soils, respectively). At each site, local meteorological conditions were monitored, avocado tree water use was quantified using heat-pulse sap flow measurement, total leaf area
Carbon and water footprinting of avocado production in New Zealand
"The avocado sector in New Zealand is growing rapidly and is driven particularly by demand in overseas markets. To develop a better understanding of the environmental impacts associated with the New Zealand avocado supply chain, an environmental Life Cycle Assessment (LCA) was undertaken of this sector, focusing on climate change and water use.
For the carbon footprint, it was found that fertiliser production and use, and fuel use, dominated the climate change impact category for orchard activities.
