Productivity, economic performance, and soil quality of conventional, mixed, and organic dryland farming systems in eastern Washington State

Summary

This 2019 peer-reviewed field study examined three contrasting dryland farming systems in eastern Washington State—conventional, mixed, and organic—to assess their relative performance on productivity, economic viability, and soil quality. The research appears to benchmark soil health metrics alongside agronomic and financial outcomes, offering comparative data relevant to systems-level farm decision-making in semi-arid conditions. The findings contribute to the growing body of evidence comparing long-term soil and economic trade-offs across farming systems.

UK applicability

Whilst conducted in a semi-arid US context, the comparative methodology and soil quality assessment framework may inform similar evaluations in drier UK regions (e.g. eastern England). However, UK practitioners should note differences in climate, soil types, crop rotations, and regulatory environment when interpreting applicability to lower-rainfall British arable systems.

Key measures

Likely measured: crop yield, gross revenue, net profit, soil organic matter, soil microbial biomass, soil physical properties, and nutrient cycling indicators across the three farming system types.

Outcomes reported

The study compared productivity, economic performance, and soil quality indicators across conventional, mixed, and organic dryland farming systems. As suggested by the title, the research evaluated multiple soil health and agronomic metrics over the study period.
