Usage

Dry Matter Content

Part of the Forage Grass analysis suite. Estimates the amount of plant material remaining after moisture removal — including fibers, carbohydrates, proteins, fats, and minerals.

Overview

Dry matter content indicates the proportion of plant material that is not water. It is a critical metric for:

Harvest timing — Knowing when forage reaches optimal dry matter for silage or hay production.
Feed quality — Dry matter directly affects nutritional density and livestock intake.
Yield estimation — Combining dry matter with biomass gives total yield in dry weight.

Process Dry Matter

GraphQL Mutation

mutation { processDryMatter( polygonId: "abc123-def456-ghi789" startDate: "2025-06-01" endDate: "2025-08-31" ) { Status Message Result { requestId } } }

Retrieve Dry Matter

GraphQL Query

query { retrieveDryMatter( polygonId: "abc123-def456-ghi789" startDate: "2025-06-01" endDate: "2025-08-31" ) { colorlegend tif png json } }

Response Format

Returns the same four output types as other analyses:

colorlegend — Static reference image for the color scale.
tif — GeoTIFF raster files for GIS processing.
png — Visual PNG images for display.
json — Statistical summaries per date.
