Identification of high-risk agricultural activities
10 August 2019
Winter forage cropping and grazing practices in New Zealand hill country can result in severe de-vegetation and erosion, and therefore have a significant negative impact on downstream water quality. Research has shown that sediment and nutrient losses from winter-grazed hill country pasture are grea...

Soil Matters
10 August 2019
An integrated approach to soil health and resilience.
Through our MBIE Endeavour funded programme (C09X1613) Soil health and resilience – oneone ora tangata ora we are exploring the concept of ‘soil health’ and what it means across New Zealand society using both a conventional science and a mātauran...

Reducing water use and nitrogen loss under irrigated cropping
10 August 2019
Soil physical properties, such as profile available water, are key influences on irrigation management, while others influence environmental outcomes, such as soil drainage and nutrient loss. Soils can be spatially variable, with varying capacity for water storage.

Managing irrigation and harvest intensity of lucerne to increase soil carbon stocks
10 August 2019
There is growing recognition of the need to increase soil carbon stocks to improve soil fertility, enhance the sustainability and resilience of productive systems, and sequester carbon dioxide from the atmosphere to offset greenhouse gas emissions.

National soil carbon monitoring system for agricultural land
10 August 2019
This study will improve New Zealand’s ability to report greenhouse gas emissions and removals under international climate change agreements and satisfy a growing desire by primary industry organisations and individual farmers to know how New Zealand’s soil carbon stocks might be changing.

Soil specific surface area
10 August 2019
Soils can store large amounts of soil organic carbon (SOC) because carbon can be shielded in organo-mineral complexes that form on mineral surfaces and protect organic molecules from microbial decomposition.

Recent progress in soil spectroscopy
10 August 2019
Sustainable land management requires reliable information about a wide range of soil properties, but the cost – both financial and in terms of time – of direct measurements for those properties, can be a burden. Proximal sensing technologies can offer an alternative to the reference laboratory metho...

Infiltrometer network
10 August 2019
One of the key soil information requirements for smart agriculture and storm water management is how fast water infiltrates into the soil at various antecedent soil moisture conditions. Infiltration data are the most important factors for estimating run-off of water applied at a known rate.

Soil Guideline Values
10 August 2019
Soil guideline value (SGV) is a generic term used to collectively describe different criteria that typically identify concentrations of substances such as nutrients and contaminants in order to manage soil quality.

Editorial - Big Data
10 August 2018
Big Data is a term coined to describe analytics characterised by a stream of extreme V’s – Volume, Variety, Velocity, & Veracity. In simpler terms, this means abnormally large data size; diverse types and forms of data; integration of traditional and real time data and delivering answers in a timely...
