VISION STATEMENT

Providing economic, social and environmentally sustainable solutions for the Southern South Island dairy farming community.

INTRODUCTION

The 295 hectare property at 105 Wallacetown-Riverton Highway, was leased by Southland Demonstration Farm Limited, controlled by the Southland Demonstration Dairy Farm Trust, on 1st June 2007, to operate as a commercial demonstration farm. The farm provides a focal point for the dissemination of information to Southern South Island dairy farmers.

The milking platform is approximately 260 ha with a further 32 ha [approximately] per year of brassicas and fodder beet for winter feed. The farm milks 790-800 cows and supplies Fonterra’s Edendale Factory targeting annual production of 340,000 kg/MS (1150 kgMS per total ha / 1300kgMS/ha off the milking platform).

KEY OBJECTIVES

Economic sustainability [profit] of Southern South Island dairying.
Environmental sustainability [land, water, animals] of Southern South Island dairying.
Social sustainability [labour] of Southern South Island Dairying.
To provide a central focal point for the dissemination of information to assist farmers to meet the challenges going into the future.

PASTURES / PASTURE RENEWAL

Pastures are progressively being renewed each year through a renewal programme that incorporates both winter crops such as swedes, kale and fodder beet and short term ryegrasses prior to new permanent pasture being sown. Half of the winter-crop area is returned to new pasture each year and the other half cropped for a second season. The farm has re-grassed approximately 1/3 of the property in the past 4 seasons. Each new pasture is a perennial ryegrass/white clover combination, with strategic placement of particular cultivars across the farm differing in ploidy (diploid/tetraploid), flowering date and more recently different novel endophytes. A small area of the farm was sown directly in short term ryegrass without clover to increase the amount of re-grassing on the farm and address some of the weed issues on farm. The ryegrass acts as a forage crop in its own right, this will be wintered cropped and returned to permanent ryegrass / white clover. Permanent pastures are sown at 20kg/ha diploid ryegrass and 25kg/ha tetraploid ryegrass with 6kg/ha white clover.
