Dr Tim Jenkins is conducting field-based soil monitoring on the focus vineyards, looking at physical and biological measures of soil health, including earthworm numbers and species, bulk density, water infiltration, soil compaction and soil structure. He is monitoring how all of these parameters change over time in both conventional and organic vineyard blocks.
Tim attended project field days in Hawkes Bay and Marlborough this spring to discuss what he looks for in soils, and how various vineyard practices affect soils, from copper use to cultivation to cover crops. Below are notes from the Marlborough field day at Wither Hills.
Tim Jenkins, director of the Centre for Sustainable Agricultural Technologies, is a soil scientist and microbiologist with a wide-ranging background in sustainable agriculture. He was manager of Lincoln University’s organic farm, the Biological Husbandry Unit (BHU), and lecturer at the University for several years.
