Turning low density chook manure into a consistent, pelletised biological fertiliser—and swapping it in for DAP at sowing. In the Riverina near Griffith, NSW, Alistair & Hugh McDonald show us their open-air compost “factory,” purpose-built pellet plant, and the on-farm results with irrigated winter crop.

Why watch:
• Slash fertiliser costs and freight with high-density pellets
• Get consistent flowability through drills/air seeders
• Feed soil biology for better nutrient efficiency
• Hear a farmer’s real-world trial replacing DAP at the same rate

Featuring:
• Alistair & Hugh McDonald — Riverina Sustainable Fertilizers (pelletised poultry-compost)
• Farmer trial: Duncan (irrigated winter crop, swapped DAP for pellets)
• Location: Near Griffith, NSW (Riverina)

What we cover: moisture management, compost temps (50–60°C), C:N ~30:1, inoculants (humics + microbes + trace minerals), hammer-milling, PLC safety, pelleting, cooling & screening, planter-friendly granules.
