A single deposit of fertiliser, either N (80g urea), P (180g superphosphate) or both was supplied at 30 cm upslope of the pole and at 15 cm depth to ‘Veronese’ poplar trees on sloping pastoral land two months after the trees were planted as poles.

Pollarding wide-spaced poplar trees on pastoral hillslopes alters root development - Research Brief 15
Water flow on pastoral slopes following rainfall transfers sediment and contributes to slope erosion. Pasture cover reduces flow rate allowing more time for water absorption. Trees also influence water flow in ways that complement and enhance the effect of pasture.

Root development in poplar and willow clones (a pot study) - Research Brief 05
A range of willow (Salix) and poplar (Populus) clones were used in the study. This information is important for river engineers, land managers and landowners seeking to match planting material to situation.

Influence of tree shading by Populus ×euramericana ‘Veronese’ - Research Brief 02
We measured and modelled pasture production over a 10-month period under poplar trees aged either 11 or 22 years (TP) and in open pasture (OP), to determine the effect of spaced conservation trees on pasture production.

Wood production of ’Kawa’ poplar in an agroforestry trial - Research Brief 14
Poplar is widely planted internationally as a forestry and agroforestry species. The poplar cultivar ‘Kawa’ has been planted in Northland as an agroforestry tree. ‘Kawa’ has a higher wood density than most other poplar cultivars, with a straight stem.

Effect of slope position on poplar growth - Research Brief 13
Trunk diameter data from two wide spaced poplar trials planted in rows, with within row spacing of 10 m, at 20 m apart up a slope are used to provide insights into how slope position affects poplar growth.

Influence of soil type on poplar root development - Research Brief 12
Poplar (Populus deltoides × nigra) Trees were grown from 3 m-long poles on pastoral hill slopes in three different soil types, pumice, sandy loam and clay loam, differing in their bulk density.

Willows, poplars and fodder - Research Brief 10
Poplar and willow provide fodder of sufficient quality and quantity to warrant using then as supplements for feeding to livestock during summer droughts. In addition to the feed quality, the tannins and phenolic glucosides present in the leaves provide pharmaceuticals benefits to stock.

Milling poplar on the farm for fencing and yards construction - Research Brief 09
Farm milled poplar provides valuable wood products for both on-farm and off-farm use e.g. treated posts, battens and timber. On-farm, the timber was used for railings and gates in both cattle and sheep yards.
