Silvoarable Systems: Maximising Cropland with Tree Rows

For UK landowners looking to make their fields work harder, silvoarable systems offer a winning combination. This practice intertwines crops with strategically planted rows of trees to create a more productive and sustainable farm. By blending the benefits of traditional cropping with forestry, silvoarable systems can enhance soil health, provide wind protection, and diversify income with timber or fruit. Here’s how you can plan, implement, and fund your silvoarable system for maximum benefit.

Why Silvoarable Systems?

At its core, silvoarable agroforestry involves planting rows of trees within crop fields, forming a partnership between trees and crops that boosts land efficiency. Here’s why this approach can be a game-changer:

1. Enhanced Land Productivity: Tree roots cycle nutrients from deep in the soil, improving soil structure and fertility.
2. Wind Protection: Tree rows act as natural windbreaks, protecting crops from wind damage and reducing soil erosion.
3. Diverse Revenue Streams: Generate income not just from crops, but from timber, fruit, or nuts.
4. Biodiversity Boost: Tree rows create habitats that attract beneficial wildlife, which can help with natural pest control.

Step-by-Step Guide to Setting Up Silvoarable Systems

Assess Your Land

Before starting, take a close look at your land:

• Soil Type and Health: Determine which tree species are best suited to your soil. Apple and hazelnut thrive in fertile, well-drained soils, while poplar trees adapt well to varied conditions.
• Water Availability: Ensure that the tree species you choose won’t outcompete your crops for water. Walnut trees, for example, are drought-tolerant and could be suitable for drier regions.
• Field Layout: Identify areas where tree rows could enhance your fields without disrupting current practices. Fields prone to wind erosion or those needing a windbreak are prime spots.

Choose the Right Tree Species

Select tree species that fit your land’s conditions and goals:

• Apple and Pear Trees: Ideal for fruit production and potential value-added products like cider or preserves.
• Hazelnut and Walnut Trees: Nut crops have high market value with relatively low maintenance.
• Poplar and Willow: Fast-growing trees that can be harvested for timber or biomass while providing wind protection.

Tip: Choose deep-rooted trees to avoid competing with shallow-rooted crops.

Plan Your Tree Rows

Proper layout ensures that both crops and trees thrive:

• Spacing: Leave 15-20 metres between rows to provide enough sunlight for crops.
• Orientation: Position rows north-south to minimise shading effects on your crops.
• Density: For fruit or nut production, opt for lower-density planting to allow tree branches to spread. For biomass or timber, denser planting can be more efficient.

Prepare the Land and Plant the Trees

• Soil Preparation: Till or plough the land and add organic matter if needed to boost soil fertility.
• Planting: Plant saplings or young trees in prepared rows. Use tree guards or fencing to protect them from livestock or wildlife.
• Irrigation: Set up an irrigation system for the early stages, especially in drier climates.

Ongoing Management

To keep your system productive, regular maintenance is key:

• Pruning: Regularly trim trees to control growth, ensure they don’t overshadow crops, and promote healthy development.
• Pest and Disease Control: Monitor both trees and crops to manage potential pest issues. Silvoarable systems naturally encourage biodiversity, which can reduce pest pressure, but vigilance is still required.
• Soil Monitoring: Test the soil periodically to maintain nutrient balance and support both trees and crops effectively.

Case Study: A Success Story from East Anglia

An East Anglian farm integrated rows of walnut trees 18 metres apart in a winter wheat field. The trees provided natural wind protection, reduced soil erosion, and boosted crop yields by 10%. Over time, the walnuts matured into an additional revenue stream, showing how silvoarable systems can enhance a farm's productivity and financial stability.

Funding Options for Silvoarable Systems

Setting up a silvoarable system can come with initial costs, but several grants can help you get started:

1. Countryside Stewardship Capital Grants:
   • TE4 (Shelterbelts): Up to £4.93 per metre for creating shelterbelts, ideal for silvoarable setups.
   • TE5 (Woodland Tree Planting): Provides £1.28 per tree, which helps cover basic planting costs.
2. Sustainable Farming Incentive (SFI):
   • Offers annual payments of up to £849 per hectare for higher-density silvoarable systems. Lower-density setups can also receive support​​.
3. England Woodland Creation Offer (EWCO):
   • Capital Funding: Covers up to 100% of planting costs, with potential Additional Contributions of up to £8,500 per hectare for added environmental benefits​.
   • Maintenance Payments: Provides £300 per hectare per year for 10 years to assist with tree care.
4. Local and Regional Grants:
   • Forestry England and Local Councils: Some areas offer additional support for agroforestry projects aligned with local environmental priorities. Contact local councils or Forestry England for potential region-specific funding.
   • Local Nature Partnerships (LNPs): These may have grants available for projects that support biodiversity and sustainable land use.
5. LEADER Programme:
   • Available in some regions, LEADER grants fund innovative rural projects that align with community and sustainability goals. Check with your local LEADER group for eligibility.

Why Silvoarable Could Be Your Farm’s Next Big Move

Silvoarable systems might sound like mixing apples and wheat, but when done right, they create a harmonious setup that benefits your farm’s productivity, soil health, and bottom line. By integrating trees into your arable fields, you’re shielding crops, enriching the soil, and investing in future profits.

Picture your fields with rows of trees working as hard as your crops—providing protection, nutrients, and an extra line on your income sheet. If you’re looking to future-proof your land, silvoarable agroforestry could be your next big step. With careful planning, practical steps, and grant support, your farm can thrive and stay productive, season after season.
