Soils of Banks Peninsula – large complexity in a small space
31 October 2023
As part of ongoing efforts to extend the coverage of New Zealand’s national soil map, S-map, a team of pedologists from Manaaki Whenua – Landcare Research, targeted one of the very conspicuous blank spots on the national soil map – Banks Peninsula in Canterbury. This significant milestone has its ge...

Tactical use of proximal sensing tools for the S-map soil survey
31 October 2023
Although the stony soils of the upper Wairau Valley, Marlborough, have underpinned the success of winemakers, they have made soil mapping there a slow and arduous task. The valley has been shaped by the Wairau River, and its soils have formed in the gravels left behind as the river changed course. A...

A farmer-friendly infiltrometer
31 October 2023
Weather events over recent years have motivated farming, industry, and environmental protection authorities to search for ways to minimise environmental pollution. One way of achieving this goal is to increase agricultural water-use efficiency and manage storm water generation more efficiently on-fa...

Soil judging competition develops skills and knowledge vital to understanding and protecting soil
31 October 2023
You don’t need experience to compete in a soil judging competition, as participants in the second National New Zealand Soil Judging Competition recently discovered. The biennial event, which took place during the New Zealand Society of Soil Science conference in Marlborough in late November 2022, ai...

Guidance on the sustainable management of surplus soils in New Zealand
31 October 2023
‘Surplus soils’ are those soils that have been disturbed through land and infrastructure development or natural processes (e.g. landslips, silt/sediment) and are unable to be beneficially used on-site. An Envirolink Tools project on surplus soils was carried out from July 2022 to August 2023. The pr...

Development of a semi-automated, inexpensive, climate-controlled plant growth unit
31 October 2023
A plant growth unit is essential for growing plants under controlled conditions so that uniform plant material can be made available for experiments to study plant responses to changing environmental conditions. It provides a controlled environment, including temperature, humidity, light intensity a...

Frozen assets: enabling access to New Zealand’s Antarctic soils heritage
31 October 2023
Since 1957 New Zealand’s soil scientists have been exploring the nature, properties, and formation of the scientifically remarkable Antarctic soils. A 2-year project, supported by a partnership between Manaaki Whenua and Te Tahua Taiao Ngā Taonga – Lottery Environment and Heritage, has culminated in...

An update on the national soil carbon benchmarking and monitoring system for agricultural land in New Zealand
1 November 2022
Every year, under the United Nations Framework Convention on Climate Change and the Paris Agreement, New Zealand is obliged to report its national human-produced (anthropogenic) greenhouse gas (GHG) emissions and removals, including changes in soil organic carbon (SOC) stocks. With average soil carb...

Diverse pasture reduces nitrous oxide emissions – but there’s a catch!
1 November 2022
As New Zealand works toward a low-carbon future there is a critical need to reduce greenhouse gas (GHG) emissions, particularly from livestock grazing systems.

Sampling event-based drainage in near real time using drainage fluxmeters
1 November 2022
Soil drainage containing chemicals and nutrients, such as from fertilisers, grazing animals, effluent, and other diffuse sources, is a key component in ground water pollution in agricultural areas. Therefore, it is important for farmers and water users to know not only the quantity but also the qual...
