Benefits of Agroforestry

Agroforestry is the practice of integrating trees and shrubs into agricultural landscapes, which can provide a multitude of benefits which may include the following. Not all of these will be suitable or necessary, depending on the land, but one or two can benefit your existing farm business and biodiversity.

The types of agroforesty and their benefits include:

1. Widening Hedges and Creating Windbreaks
   Thickening hedgerows and establishing windbreaks can help to protect crops from strong winds, reduce soil erosion and provide shelter to farm animals. Whilst there may be some productive land removed around the edges, reducing yields, the costs can be outweighed by the wider hedges promoting healthier crop yields and improves overall site conditions. The wider hedges will also provide a large habitat for birds and mammals to live and feed.

2. Providing Shelter Belts and Areas
   Implementing shelter belts allows for less harsh microclimates, which can enhance the growth conditions for both crops and livestock. These belts offer refuge from extreme weather, creating a more conducive environment for ecological balance and reducing the need for intervention during harsh or extreme weather events.

3. Adding More Hedges with Regularly Spaced Trees
   Enriching hedgerows with regularly spaced trees increases biodiversity, provides habitats for wildlife, and enhances the aesthetic quality of the landscape while contributing to soil health and moisture retention. Smaller fields can also help prevent soil erosion and run off during periods of heavy or intense rain. Tall trees should aim to be planted every 50m.

4. Creating Wood Pasture or Traditional Style Orchards
   Wood pasture combines grazing with trees, facilitating forage under tree canopies. Similarly, traditional orchards contribute to food production while maintaining biodiversity and providing habitat for various species. Both of these can form part of the standard rotation of land.

5. Creating Copses and Small Woodlands, Particularly in Field Corners
   Small woodlands or copses in less productive corners of fields can serve multiple functions, including enhancing biodiversity, improving habitat connectivity, capturing carbon, and offering sites for timber and fuelwood production. Depending on the size, funding could be secured to cover the cost of planting.

6. Establishing Low Density Tree Planting (such as parkland)
   Low density tree planting allows for the continuation of agricultural practices while optimising land use. This method enhances the aesthetic value of the landscape and promotes ecological functions, such as increasing soil stability and nutrient cycling.

7. Preventing soil loss and erosion
   Trees prevent soil loss with extensive root systems that bind soil and reduce erosion risk. Their roots stabilize the ground, enabling it to withstand heavy rains and strong winds. Additionally, tree canopies intercept rainfall, slowing its descent and reducing soil impact. This maintains soil structure and moisture, promoting healthy ecosystems and preventing land degradation. Healthy tree populations significantly contribute to soil conservation and environmental resilience.

There are a further terms that are regularly used when discussing agroforestry. These are:

Silvopasture

Silvopasture is an agroforestry practice that incorporates trees and grazing livestock into a single management system. This method contributes to soil health by improving nutrient cycles, reducing erosion, and maintaining moisture levels. The shade provided by trees helps reduce heat stress in animals and can enhance the quality and quantity of forage. Additionally, the combination of trees and grazing can create a diverse ecosystem that supports beneficial wildlife and improves resilience against pests and diseases.

Silvoarable

Silvoarable practices involve the integration of trees with crops in a farming system. This approach encourages greater biodiversity and can lead to improved pest management, as well as enhanced soil structure and fertility. The presence of trees can help moderate temperatures, retain soil moisture, and reduce wind impacts, all of which contribute to more stable and productive crop yields. Furthermore, silvoarable systems can provide additional income from timber and non-timber forest products, diversifying the economic returns for farming operations.
