Assessment of Empirical CPT–Vs Correlations using Direct‐Push Crosshole Data from Shallow New Zealand Soil Deposits

New Zealand Journal of Geology and Geophysics, Volume 69, Issue 1, March 2026.
This article assesses the performance of multiple cone penetration test–shear wave velocity (CPT–Vs) correlations based on a database of over 2,100 CPT–Vs data pairs obtained from co‐located shallow (≤10 m) CPT soundings and direct‐push crosshole tests in New Zealand.

Tree Cultivation in Hydroponic Systems: Effects of Substrate Type and Electrical Conductivity on Nutrient Status and Growth in Soilless Fig Tree

New Zealand Journal of Crop and Horticultural Science, Volume 54, Issue 1, March 2026.
The fig tree has traditionally been cultivated in open fields for its fruit. However, recent advancements have enabled the cultivation of fruit trees in greenhouses. This study investigates the effects of hydroponic cultivation of fig trees, focusing on growth parameters and nutritional status under two substrates, coconut coir and pumice, and three ...

Reduction in Suspended Sediment Loads Following Canopy Closure: The Impact of Pasture‐To‐Pine Plantation (P.radiata) Conversion in a Headwater Catchment

New Zealand Journal of Marine and Freshwater Research, Volume 60, Issue 1, March 2026.
Plantation forestry is an important land use in New Zealand (currently 7% of the area), and recent central government incentives for tree planting will likely result in further increases in the future. Plantation forestry in New Zealand often occurs on steep, high‐erodible land, often as a form of catchment restoration and/or erosion control.
