Silvoarable systems in Spain

Description of system

In Spain, the "Bosques Naturales" company is conducting silvoarable experiments with walnut (Juglans spp) clones and maize (Zea mays).

Initial stakeholder meeting

An initial stakeholder meeting, with 14 participants, was held in Galicia on 21 October 2014. The most positive aspects of the silvoarable system were perceived to be the business opportunities, the originality and interest, the feasibility of the project, the diversity of products, and the general environmental benefits. The negative aspects included the complexity of work, and labour and management costs, and losses due to wildlife. Integrating trees, maize and medicinal plant production, and issues of tree protection from animals were identified as possible areas for research.

The University of Extremadura in Spain has also established a stakeholder group which is interested in integrating cereal production and high value walnut production. The initial stakeholder meeting is reported in work-package 3. However some aspects of the work is particularly focused on comparisons between different varieties of wheat and barley beneath walnut. 

If you would like to know about the activity of this group, please contact Prof.María Rosa Mosquera Losada ( Dr Gerardo Moreno (

Download the initial research and development protocol

A research protocol developed by the stakeholder group focused on the growth of cereals within high value walnut plantations (which was originally reported in work-package 2) near Toledo in central Spain was produced in March 2015.  A research protocol on cultivation of medicinal plants and maize between wild cherry in Galicia was also produced in March 2015.
