Kernza perennial crop evaluation for sustainable agroecosystem stability
Comparative field study of Kernza perennial grain versus conventional crop rotation to assess soil health, reduce agrochemical inputs, and lower fossil fuel dependence. Two-year randomized block trial analyzing soil parameters, fauna, and greenhouse gas emissions.
Overview
This research evaluates the agronomic and environmental performance of Kernza, a novel perennial grain crop, against a typical regional crop rotation. Perennial cropping systems mimic natural grassland dynamics, potentially reducing soil degradation, minimizing agrochemical and fertilizer use, and decreasing dependence on fossil fuels. The project aims to generate empirical evidence on whether Kernza can support more stable agroecosystems while maintaining productive agriculture.
Technical specifications
Experimental design:
- Randomized block design with three replicates (n=3), each containing two 3 m x 3 m plots
- Two treatments: Kernza perennial crop versus typical regional crop rotation
- Minimum trial duration of two years for accurate analysis
Measured parameters:
- Soil physical and chemical properties measured successively over time
- Soil fauna composition and activity
- Greenhouse gas emissions from both cropping systems
Scientific rationale:
- Builds on prior research showing higher agroecosystem stability in closed grassland sites with maximal litter decomposition and nutrient cycling
- Draws on established evidence of Kernza benefits demonstrated in U.S. studies
- Tests whether perennial cropping can replicate natural grassland dynamics in agricultural settings
Technology readiness level
This is an early-stage field research initiative requiring collaboration with partners who have expertise in soil science and crop systems. The proposal is seeking a partnership to support experimental design, data collection, and analysis. Validation requires a multi-year commitment to capture meaningful differences in soil health, biodiversity, and emissions between the two cropping systems. The research is positioned at the foundational experimental stage, with outcomes intended to inform sustainable agriculture practices and potential scaling of perennial crop adoption.
