Benchmark Value

10 individuals/m²
Direction: Lower is desirable ↓
Form: MaximumOnly

Scoring Curve

Scoring curve unavailable

The scoring engine could not generate a curve for this benchmark context. The primary form is CompositeFramework, but the benchmark data may be missing required fields (e.g., optimal range bounds for an OptimalRange benchmark). This is typically a data quality issue in the benchmark pipeline.

Evidence & Context

The key finding was that 72% of the surveyed cropping paddocks contained fewer than 10 grass weeds/m² at the time of crop anthesis (flowering).

Metric Definition:

Density of grass weeds per square meter in-crop at anthesis (flowering)

Benchmark Definition:

This benchmark represents the highest documented level of weed suppression in temperate Australian cropping systems, indicating very low weed densities at crop flowering.

Justification:

Represents the best available condition for in-crop weed management within temperate Australian cropping systems, derived from a high-quality agronomic study.
