Sharemilkers Dave Van Den Beuken & Jenny Buckley milk 550 cows on the Jones Family Trust Farm at Tauwhare. They have been using the effluent system designed and installed by AgFirst Engineering since 2013.The farm dairy, feed pad and large feed bunkers all drain into two 39m long drying beds fitted with weeping wall panels. The green water stored in the 4,000m3 pond is used to flood wash the feed pad. Irrigation through both a travelling irrigator and stationary pod sprinklers is designed to meet a range of application depths and rates determined by the Hamilton clay soils.
