Technical readiness: Agroforestry is a well-established practice, though ongoing research continues to refine optimal species combinations and system layouts for effective weed suppression across diverse European climates.
Ease and efficiency of implementation: Requires site-specific planning to select appropriate tree and crop species based on soil conditions, climate, and overall farm management objectives.
Need for training and education: Farmers benefit from advisory support and demonstration sites to better understand tree–crop interactions, weed suppression strategies, and system upkeep.
Need for investment: Initial costs for tree planting, mulching systems, and fencing (when integrating livestock) can be substantial but provide long-term environmental and economic benefits.
Description
Agroforestry techniques offer a holistic approach to weed control by integrating trees, shrubs, and perennial plants into horticultural production systems. These methods enhance natural weed suppression through shading, plant competition, and improved soil health, thereby reducing the need for chemical herbicides.
In regions with high rainfall and acidic soils—such as Atlantic Europe—agroforestry contributes to soil structure stabilization, erosion control, and biodiversity enhancement. Common practices include intercropping with nitrogen-fixing shrubs, alley cropping (growing vegetables between rows of trees), and the use of mulch-producing species to maintain permanent ground cover. In some systems, integrating livestock such as cattle or poultry for targeted grazing can further suppress weeds, especially in woody crop setups.

Explanation
Agroforestry is considered a best practice because it enhances natural weed suppression by modifying the microclimate and intensifying plant competition. This reduces the need for herbicide use and supports the objectives of the EU Green Deal. Additionally, it improves soil health and moisture retention- key benefits in humid or erosion-prone areas. By fostering a more diverse ecosystem, agroforestry also supports pollinators and natural pest control, contributing to overall farm resilience and sustainability.
Advantages
Weed suppression through shade, competition, and organic mulches.
Diversifies farm income by integrating tree crops, fruit production, or medicinal plants.
Can be integrated into existing farm layouts with minimal disruption.
Increases carbon sequestration, improves water retention, and supports soil regeneration.
Drawbacks
Initial weed pressure may require manual or mechanical control before the system stabilizes.
Establishment costs can be high, and returns may take several years.
Requires knowledge and planning to optimize tree-crop interactions and spacing.
Some woody species may compete with crops for water and nutrients if not properly managed.
Technical Aspects
Policy Recommendations
Policymakers should introduce financial incentives to support farmers who adopt woody perennials as part of weed control strategies, thereby encouraging the integration of agroforestry into horticultural operations. Grants and subsidies should focus on covering initial establishment costs, including tree seedlings, soil preparation, and fencing for livestock integration. Additionally, research funding should be directed toward developing best practices for tree–crop combinations that balance effective weed suppression, crop productivity, and soil conservation.
Enhancing knowledge-sharing platforms and advisory services would further support the transition by providing training on agroforestry design, species selection, and system management. Agroforestry should also be integrated into national and EU-wide agricultural sustainability plans, as its potential to deliver ecosystem services, reduce pesticide dependence, and boost biodiversity and climate resilience makes it a vital component of sustainable horticultural systems.
