Soil Organic Carbon (SOC)

AUS-ASP-AGR-SOC General Moderate confidence

Benchmark Value

2 %

Direction: Higher is desirable ↑

Form: Point

Scoring Curve

Scoring curve unavailable

The scoring engine could not generate a curve for this benchmark context. The primary form is Point, 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 resulting benchmarks, representing a high level of ecological function achievable under best-practice regenerative cropping, are presented in Table 1. ... Clay ... 2.0

Metric Definition:

Soil Organic Carbon (SOC) is the carbon component of soil organic matter (SOM), which is derived from the decomposition of plants, animals, and microorganisms.

Benchmark Definition:

Proposed 'Best Available Condition' Benchmark for best-practice regenerative cropping in Australian arid zones (0-10 cm).

Justification:

Derived from the upper end of the 'moderate' health range in a large-scale regional study (SA MDB), reflecting achievable targets under best-practice regenerative management.
