Event description


Biochar is being produced and applied around the world in a growing number of commercial agriculture systems. Interest is also growing in NZ but training in biochar production and application techniques has generally, not been available in NZ. To help fill this need, NZ Biochar Ltd and AllBlackEarth are planning a series of national biochar workshop tours, beginning in May 2018 with an initial focus on horticulture.

Five venues have been selected for the initial tour spanning the length of NZ. The focus of these workshops will be on vineyards, kiwifruit, orchards, trees and other perennial crops. Workshop attendee numbers will be limited to 12-20, depending on venue. The dates and venues are:

  • 24 May - Cromwell (confirmed)
  • 29 May - Nelson (confirmed)
  • 1 June - Waihi (confirmed)
  • 5 June - Whitford (DATE AND VENUE TO BE CONFIRMED)
  • 8 June - Gisborne (confirmed)

Public biochar events are also being planned near each venue to cater to public interest in the multi-faceted beneficial impact biochar can bring to agriculture and the environment.

Workshop details:

Otago Workshop location: NZ Nuts, Cromwell - Thursday, 24th May 2018

NZ Nuts 3

NZ Nuts 4The property is certified organic with Otago Organics (Organic Farms NZ) and has been practicing organic horticulture for a number of years. Their practice is guided by Elaine Ingham and the use of compost and herbal teas and they are transitioning to some biodynamic practice. North American and European cultivars of walnut have been grafted on the property along with almonds and some chestnut trees. A farm fire destroyed the walnut research orchard 20 years ago so all trees are less than 20 years old. They also produce heritage tomatoes and garlic – with all crops sold through the Otago Farmers Market and by mail order. Those interested are welcome to participate in a farm walk either at lunch time or at the end of the workshop whichever is most appropriate. They will be attending the workshop as participants.

Chaos Springs website link

131 Deam Road, Waihi Link to Map

Chaos Springs is a 200 acre mixed cropping farm raising pasture, animals, fruit, and vegetables in the Waitawheta Valley near Waihi.

"We make compost and soil management tools to help growers take control of their soil fertility. To manage soils well we need to understand all four realms of soil function: soil biology, minerals, energetics and the plant—soil relationship. We believe most soil fertility issues can eventually be handled within the farm boundary."

Chaos Springs has been host to a wide range of interesting workshops and tours. Recent workshops have covered soils, composting, sustainable pasture and horticulture systems and farm equipment innovation. You can check out their website from the photo-link above.

Gisborne Workshop: Kaiaponi Farms - Friday, 8th June

Kaiaponi Farms

Kaiaponi Farm Ltd, 555 Matawai Road, Gisborne Link to Map

"Kaiaponi’s story starts in 1907, when the land was used for cropping. The land has since been used to grow many fruits and vegetables including apricots, avocados, beans, grapes, pears, squash and tomatoes. Today Kaiaponi is a leading grower of apples, kiwifruit and feijoas.

Kaiaponi is a privately-owned business based on family values. The importance of innovation and sustainable growth has always been central to our ethos. This has been demonstrated in the past by our early investment in gold kiwifruit, high yielding apple varieties, designated grower trial blocks and our continual investment in post-harvest technology.

Today, we grow the best varieties to meet market demand and have the best technology to pack and distribute your fruit. Even with our strengths we’re not resting on our laurels. Kaiaponi will continually evolve, redevelop and build the right partnerships to continue our growth into the future."

If you would like to attend a workshop in your region, then please get in touch.

PUBLIC EVENTS - Biochar education/discussion forums

We hope to organise public biochar gatherings at venues in each workshop region. These could be general educational presentations or more in-depth examination of biochar utility for local agriculture, environmental or energy applications. Getting these events organised may depend on finding local help at each region we visit. Please get in touch if you are willing and able to help.
