Map
Soil erosion losses and contributions from underlying sources/causes
Regional maps of modelled soil loss from surface erosion across Aotearoa New Zealand are provided in .tif fomat for use in GIS. These large .zip files (use 7-zip or…
Guidance
Using farm dairy effluent on free-draining soils
Additional measures, on top of regulations and industry good practice and guidelines, may be needed to minimise P losses from FDE applied to free-draining soils.…
Journal Article
Assessing soil health following conversion from forestry to pasture in Canterbury
Soil health was assessed across land conversions from forestry (Pinus radiata) to irrigated dairy pasture. Samples were collected and indicators of soil fertility, organic matter,…
Journal Article
A Global Database of Soil Plant Available Phosphorus
Soil phosphorus drives food production that is needed to feed a growing global population. However, knowledge of plant available phosphorus stocks at a global scale…
Journal Article
Factors controlling shallow subsurface dissolved reactive phosphorus concentration and loss kinetics from poorly drained saturated grassland soils
Shallow subsurface pathways dominate dissolved reactive phosphorus (DRP) losses in grassland soils that are: poorly drained, shallow, or have a perched water table in wetter…
Journal Article
A new robust hybrid model based on support vector machine and firefly meta-heuristic algorithm to predict pistachio yields and select effective soil variables
Pistachio production is an economically important crop that grows in arid environments. To predict yield and sustainably manage the use of natural resources such as…
Summary
New test for biological soil health
A quick way to assess the biological health of soil has been developed using molecular techniques to measure earthworm activity, but this needs more work…
Technical Report
Biological test of soil health using molecular techniques: Final report
During the feasibility stage of the project, we were able to identify suitable primers for the most common earthworms found within each earthworm ecological group…
Technical Report
Dispersed forage feeding to minimise negative impacts on soil and water quality: Final report
This project has identified there is huge promise in the harvesting system, however a more detailed investigation is required to realise the full potential of…
