Research Summaries

This review of the research into organic poultry management focuses on breeding, rearing, housing, health and disease, medication and to a lesser extent nutrition which is covered in another Review. The results are analysed and practical recommendations made for the development of organic poultry systems and their management.

Advisory tools are an invaluable aid for advisers in providing farmers with the necessary information for analysis and planning of all aspects of the farm. The review of Advisory Tools provides access to and a comprehensive list of all the templates, calculators and analytical tools available to organic advisers, covering the environment, business, soils and animal husbandry.

“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.

Optimising the management and supply of nitrogen to crops remains one of the greatest challenges for organic producers. This Research Review covers a large number of research projects and summarises key aspects of nitrogen accumulation, management and utilisation through the use of legumes, catch crops, manures, cultivations and soil management.

The supply of nutrients to plants is dependent on the complex relationship between soil mineral levels, soil structure and type and biological activity. This review looks at the soil analysis techniques available to organic farmers and the supply and availability of nutrients to plants through the use of mineral additions and soil management.

The concept of a “living soil” in which biological activity makes nutrients available to plants and fixes nitrogen is central to organic farming. This Review considers the research into the complex role of soil life and looks at the analytical techniques and management strategies which are available to us in the organic management of soils.

Compost is considered by many to be the holy grail of organic farming and growing. This review looks at the research and explores how compost varies according to the ingredients and the way it is made. It studies the evidence for compost improving plant health, quality and promoting disease resistance and summarises the situations in which compost is most useful.

This review seeks to address the role and management of herbal pastures for animal health, productivity and product quality. It involves a review of research and focuses on the use of herbal ley mixtures and varieties and their role in animal health and growth, meat quality, production and yield and climate change issues.

This Review of several research projects which focus on the financial performance of organic farming, demonstrates the profitability of organic farming businesses and how they compare with conventional farms. It analyses the factors which affect profitability and explores how the data can be used in benchmarking as a means of identifying the level of performance of individual farms and what changes in management can be made to improve profitability.
