People, planet and profit

George and Sharon Moss run two adjoining dairy farms near Tokoroa in South Waikato, and in this case study they show how they use the farm's greenhouse gas figures alongside profitability data to decide where to focus their efforts each season.

Genetics, nitrogen management and herd size decisions sit behind their falling methane and nitrogen leaching numbers, and George is frank about weighing environmental gains against milk price and production. He also points to the tools farmers can use to find their own numbers.
