Adaptation of evidence-based intercropping systems for North American crop production

Overview

This research initiative adapts proven European intercropping practices for North American crop production. The project combines centuries-old traditional European farming methods with modern evidence-based knowledge, using a techno-economic framework to identify which intercropping systems can deliver both financial and environmental sustainability improvements. The approach addresses the growing pressure on North American farmers from regulators demanding more responsible agricultural practices and from declining soil health caused by unsustainable measures.

The core hypothesis is that meaningful similarities between European and North American agricultural conditions—including soil types, soil microbiota consortia, mechanization levels, price structures, and regulatory environments—create a strong foundation for transferring successful European intercropping practices. The research focuses on crops such as corn, soybean, canola, and sorghum, and explores intercrops including St. John's wort, mustard, sedge, and safflower.

Technical specifications

Research methodology:

• Comprehensive review of existing farming practices in Europe and North America with focus on corn, soybean, canola, and sorghum
• Managerial and techno-economic analysis of market conditions and regulatory frameworks
• Identification of the most promising intercropping practices suitable for transfer from Europe to North America
• Selection of test locations and detailed agronomical analysis including nutrient availability, soil organic matter quality and quantity, and air-water-nutrient management of soil
• Design and implementation of a robust experimental matrix across 8 locations with 6 repetitions
• Supervision of commercially scaled operations
• Multidisciplinary evaluation and final recommendations

Key intercrops under investigation:

• St. John's wort
• Mustard
• Sedge
• Safflower

The research team brings direct experience in designing farming practices in regions including the Caucasus and Southeast Asia, and has verified European intercropping methods in North and South Africa, where they significantly increased crop yields and improved soil fertility—particularly water, nutrient, and air management in the topsoil.

Technology readiness level

This project is at an early-to-mid stage of validation. While European intercropping practices have been verified in African contexts with demonstrated yield increases and soil fertility improvements, the transfer to North American conditions has only been partial to date. The current research program is designed to bridge that gap through a structured multi-location experimental program. The project has a defined budget covering materials and services ($15,000) and personnel costs ($35,000), and seeks collaboration partners to support the experimental design, location selection, and implementation phases.
