Amendment-assisted low-grade rock phosphate enhances maize productivity and phosphorus availability in contrasting soil orders

Efficient phosphorus (P) management is essential for improving crop productivity while reducing dependence on energy-intensive, highly soluble P fertilisers. Low-grade rock phosphate (RP) is an underutilised, economical indigenous P source, but its agronomic effectiveness is often limited by low solubility and slow...
