Agriculture is becoming increasingly intensified through irrigation, increased nitrogen inputs and a change in grazing animal from sheep to cattle. These changes have the potential to affect earthworms, an important component of the soil biology. Ove

This study aimed to determine which practices resulted in the greatest establishment (plant density) of a range of grasses, legumes and herbs at four geo-climatically different hill country sites in the North Island (three sites) and South Island (on

The sustainability of using irrigation to produce food depends not only on the availability of sufficient water, but also on the soils ‘response’ to irrigation. Stocks of carbon (C) and nitrogen (N) are key components of soil organic matter (SOM)

There is a growing interest in forage mixtures (Diverse pasture; e.g. containing grasses, legumes and herbs), especially those with a greater tolerance of dry conditions and a decreased nitrogen (N) content (reducing N losses), compared with ryegrass

The major limitation to perennial ryegrass-based systems is low soil moisture which reduces perennial ryegrass growth. irrigation can maintain adequate soil moisture levels for pasture growth, however, the associated cost requires high levels of fora

As the availability of water for irrigation becomes more limiting it is important to use the available water effectively and all potential avenues for improving irrigation efficiency should be examined. Improving irrigation system uniformity can lead

Recent developments in cereal breeding for forage production have given the potential to greatly increase annual forage dry matter (DM) production. This paper reports on the findings from two cereal forage production trials on irrigated Canterbury la

Response to drugs can vary between individuals and between different ethnic populations. The biological (age, gender, disease and genetics), cultural and environmental factors which contribute to these variations are considered in this review. The mo

Sire breed effects were studied in 1080 lambs born over three years to Merino ewes and 6–10 sires each of Merino, Poll Dorset, Border Leicester, Texel, Oxford Down, and Suffolk breeds. Ewes bearing crossbred lambs required more assistance at lambin

The effect of two contrasting forage supply options on forage and sheep production was evaluated on irrigated farmlet systems at Winchmore, mid Canterbury, over 3 years. One system was based on perennial ryegrass pastures (Control), and the other on
