Crafting Quality Compost for Viticulture

Monday 20 September 2021 9am -1:30pm

Wirra Wirra, McLaren Vale

 Presented jointly by the Australian Organics Recycling Association, AORA and the National Association for Sustainable Agriculture Australia, NASAA

Key Presenter: Tim Marshall, TM Organics and NASAA Chair

An opportunity to learn from a composting and organic farming guru and from iconic vineyards in the beautiful McLaren Vale region of South Australia. We will examine different approaches to making high-quality compost at the scale required on farm.

This event, presented jointly by AORA and NASAA, will:

•                    Feature Tim Marshall providing a workshop on composting. Tim masterfully blends composting theory with decades of practical insight.

•                    Shared learning as composters get introduced to biodynamic growing principles and as growers are introduced to best practice in organics recycling.

•                    Get up close to the compost heap at Wirra Wirra with Anton Groffen. We’ll workshop how he oversees composting of winery and vineyard byproducts.

•                    Get down to earth with Ben Paxton from Paxton Wines and other organic and biodynamic farmers along with Peter Wadewitz from Peats Soils on how composters and growers collaborate to make great compost.

•                    Get discussion going on the opportunities for increasing landfill diversion by composting kitchen waste and grapes (sampled in the lead up to Vintage).

There will also be a unique opportunity to get up close to soil and vines at Wirra Wirra to better understand the methods and benefits of applying compost, mulch, as well as the broader Biological Input Farming principles taught by Tim.

Tim Marshall is a founder and first Chair of NASAA. He is a trainer, author and consultant with long experience in compost, organic growing and certification.
