Appendices - Development of two methods to combat perennial sow thistle (Sonchus arvensis L.) and Canada thistle (Cirsium arvense) in organic field crop production -

Field experiments on two large-scale farms tested the use of two types of spring fallow to suppress sow thistle and Canada thistle.  Spring fallow was followed by either buckwheat (for harvest) or a vigorous green manure crop. Appendices include: detailed methodology, photos of machines and field areas and field data results.
