• Channelling the right tools for flood management and runoff
  We outline promising early indications from DairyNZ's work with a Canterbury research group. These suggest that 'two-stage channel' drains could be used to benefit New Zealand's agricultural sector, improving flood mitigation and water quality and ecosystem outcomes.
• Multiple factors inform methane reduction targets
  Science can only partly inform the setting of methane reduction targets, as they also need to balance social, economic, environmental and equity issues. Find out why – and how methane differs from other greenhouse gases when it comes to target-setting.
• How much pasture and crop could potentially be eaten on your farm?
  Many dairy farms can improve their performance when it comes to increasing the amount of pasture and crop eaten by their herds. We profile a tool which might enable farmers to accurately estimate that potential on their own farms.
• Cutting to the chase: the effects of pre-graze mowing
  DairyNZ's Jane Kay looks at mowing before grazing (pre-graze mowing) as a strategy for achieving target pasture residuals. Does research suggest this practice improves cow and pasture performance?
