Agronomic, Economic and Ecological Relationships in Alternative (Organic), Coventional, and Reduced-till Farming Systems
Department of Plant Science, Department of Economics
The objectives of the experiment station trials were to:
• Measure yields in alternative, conventional and reduced-till farming systems.
• Compare whole-farm economic performance.
• Measure whole-farm productivity of the systems.
• Determine influence of farming system on soil nutrient relationships, soil temperatures, soil water content, bulk density, residue cover, and snow catch.
• Compare populations of plant feeding, predaceous, and microbial feeding nematodes.
• Determine populations of fungi and bacteria, and measure mycorrhizal associations and soil fungistatic properties.
• Determine effect of farming systems on earthworm populations.
• Determine weed species present and densities.
• Measure beneficial and harmful arthropod populations and measure insect damage.
• Compare the relative sustainability of the various systems.
This list of objectives represents various interests of the researchers and also reflects an attempt to obtain a holistic view of the processes that constitute a farming system.
