When Fertilizer Prices Rise, Fields Must Lose Less
When fertilizer costs rise, every kilogram of soil and nutrient lost to runoff becomes more expensive. Field resilience helps farmers keep more of what they invest.

Vetiver holds ground when nothing else does.
VSF helps communities and local partners use vetiver to protect soil, water, and fragile land — across Africa, Latin America, and beyond.
Learn what vetiver is ↓What is vetiver?
A deep-rooted grass for soil and water protection.
Vetiver is a practical grass used around the world to slow runoff, hold soil in place, and make fragile ground easier to manage. Its roots reach 3–5 metres deep — that depth is what holds a hillside through heavy rain.
Learn about vetiver
01
Plant in rows
Vetiver is planted in contour hedgerows across slopes, following the land's natural grade.
02
Roots anchor the soil
Within two seasons, roots reach 3–5 m deep, locking soil in place against heavy rain and runoff.
03
Water slows and infiltrates
Hedgerows act as natural silt traps, slowing runoff and pushing water into the ground instead of off it.
04
Land stabilises
Fields, roads, and slopes become more productive and resilient with minimal ongoing maintenance.
