About Tenco
Tenco is one of New Zealand’s largest exporters of forest products. We have built to this position since 1991 when the company was set up to export lumber to growing Asian export markets.  Experience and reputation count; from small beginnings Tenco has become the largest independent exporter of New Zealand lumber and New Zealand’s 4th largest log exporter.  Tenco has a regular shipping program of their own log vessels and in combination with these and other ships currently calls  at 7 New Zealand ports (5 North Island and 2 South Island).
 
Tenco buys standing forests.  Tenco currently has a number of forests which they purchased at harvestable age to log over a number of years for export and domestic markets.  Tenco also regularly buys smaller tracts of forest to harvest immediately or immature forests to hold until harvest time.  Tenco is interested in broadening  the  base of owners from whom it purchases forests and stands of trees.  A deal with Tenco is a certain transaction.  The owner and Tenco will agree on a value of the tree crop and then Tenco will pay this amount to the owner either in a lump sum amount or on rate per volume unit out-turn from the forest depending on the nature of the tree crop.
 
Tenco knows there are a lot of farmers who have trees that are close or ready to harvest and will be asking themselves how they should proceed with the sale of their trees.  For some farmers the kind of certain transaction with money in the bank could well be appealing. Tenco is actively interested in buying harvestable forests or trees from areas including all the North Island (except the Gisborne and East Coast districts) and Nelson & Marlborough in the South Island .
 
If you own a forest in this area (16 years and older) and are ready to enter into this kind of agreement Tenco is interested to develop something with you.

Digging the Good Dirt on Soil Bugs

Wednesday, October 07, 2015

Volunteers Wanted: Scion soil scientist Simeon Smaill is looking for volunteers to help with a series of trials he is running around the country.  He is looking at the effect of different nursery practises on early tree performance in the forest.

Background:  Simeon gave a very good background talk on this work to a small group of MDFFA members on Friday 15th, Sept.  Much of the talk was on the all important interactions between trees and the mycorrhizal fungi that live in association with them, assisting in the uptake of key nutrients. Without appropriate mycorrhizal fungi most trees just fail to grow, yet very little consideration has been given to managing or protecting these key players in the nursery. There are also other microbes that affect stress responses, including drought.

There has been little change in nursery practise since the 1980s, when it was felt that they had the systems to meet customer specifications for seedlings regarding height, diameter and root development. But there has been little consideration of the effects of nursery practise on subsequent tree performance in the forest. And it is known that the fungicides and soluble fertilizers used, often heavily, in the nursery adversely affect the beneficial soil microbes.

There are five common species of mycorrhizal  fungi found in nurseries, and although there are 20 or more other species that can "infect" radiate pine, Simeon says getting them into nursery stock will be difficult without a clear niche being available. Fungi not only have to battle fungicides and fertilizer, it is also open warfare between different fungi. Unfortunately the best mycorrhizal fungi are also the most sensitive to fungicides and fertilizers and hence the logic in assessing nursery practise effects on early forest performance. . 

Simeon says there are four key areas being examined in nursery practise:

  1. Physical management:  This includes stocking rates in the seedling beds and its effects on root development, nutrient levels, topping and undercutting of seedlings.
  2. Microbial interactions including the mycorrhizal and growth promoting microbes that improve nutrient uptake, stress tolerance and growth rates. There is also the possibility of using "friendly" microbes, notably Trichoderma spp., to compete with pathogens.
  3. Chemical management including fertilizers and fungicides, but also the possibilities of using plant hormones to produce fatter rather than taller seedlings.
  4. Tree genetics. Everything is treated the same in the nursery but different genotypes do vary in growth rate, stress responses and also their ability to recruit useful microbes.

Early work has already shown that the effects of nursery practise can influence forest performance for at least five years, covering the vital period when seedlings are competing with weeds.

Simeon is now looking for a wider range of different sites to conduct trials starting in 2016. These would only involve 180 trees, (3 replicates of 3 treatments, with 20 trees in each replicate) and Simeon wants as wide a range of soils, climate and other conditions as possible. Interested planters can contact Simeon at simeon.smaill@scionresearch.com, 03 364 2949 ext. 7833, or 0212 666 305.  Alternatively contact Denis Hocking on jdhocking@xtra.co.nz or 06 322 1254

Further to this item, it is worth noting that our nurseryman and MDFFA Vice-President, Patrick Murray is to the fore in this work.  He is one of the new generation of nurserymen working on the next step, not least his work on redesigning seeder drums.

Soil microbe/plant interactions are becoming a hot topic internationally and there is a very good, readable, review in a recent copy of Science, (vol 349, pp. 680-83, 14/8/2015). There is a lot more going on down there than I ever realised. If you would like a copy contact me.
