Controlling pests and diseases in organic field vegetables - Download the review here (PDF 183KB) or here (.DOC 201KB).
This review provides a summary and analysis of the most recent research on pest and disease control in organic field vegetables. Recognising that organic farming involves a whole systems approach it focuses on: Management (forecasting, seed treatments) and rotations to prevent pests and diseases, varieties and breeding for organic systems, products being developed for organic systems, biological control measures (fungi, compost, biofumigants), other strategies (predator support, distractants) and potential for new products.
Dairy cow breeding for organic farming - Download the review here (PDF 169KB) or here (.DOC 172KB).
Organic farming requires that in the choice of breeds or strains, account must be taken of the capacity of animals to adapt to local conditions, their vitality, and their resistance to disease. In addition, breeds or strains of animals shall be selected to avoid specific diseases or health problems associated with some breeds or strains used in intensive production. This review considers the research into organic dairy cow breeds and breeding, it discusses the need for a specific organic approach to breeding and cross breeding and makes some clear recommendations for selection priorities.

Non-inversion organic arable cropping - Download the review here (PDF 142KB) or here (.DOC 233KB).
"Non-Inversion Tillage" (NI) involves any cultivation system which does not seek to substantially invert the soil profile. For the purposes of this review, literature that refers to minimum, conservation and reduced tillage and also direct drilling techniques have been consulted. The review identifies the likely benefits and possible challenges inherent in moving away from inversion tillage and points towards some very successful commercial experience of NI.
