Farm Source guide - Optimise nitrogen fertiliser
Learn how to plan, time and target nitrogen fertiliser so more of it ends up as pasture growth.

This guide from NZ Farm Source's On-Farm Efficiency Hub covers how to grow, manage and use pasture and crop, from renewing paddocks and choosing species to monitoring quality and reducing feed waste.
It links to DairyNZ tools for pasture management and feed budgeting, and sets out how extra homegrown feed eaten can lift production, cut supplement costs and lower the farm's imported feed footprint.
