Vetiver Mulch & Terrace System

Terrace Calculator

Design your terraces, count the vetiver slips you need and estimate your mulch. The drawing and results update as you type.

45° means the slope is as wide as it is high. Height is the vertical step between two terraces.

m³/t

How many cubic metres one ton of harvested biomass fills. Depends on how finely it is chopped and how dry it is.

How it works
  • Terraces are flat; vetiver rows are planted on the slopes that join them.
  • Initial mulch counts only the rows you plant on day one.
  • Mature mulch assumes the slopes fill with dense strips.

These are planning estimates. Real yields depend on variety, climate, soil and how you cut and handle the biomass.
