A guide to organic grassland Organic Eprints
Philipps, Lois.
Organic farming systems in the UK are traditionally based on ley/arable crop rotations. Up to 70% of the farmed area comprises of mixed grass and legume leys. These leys offer a powerful mechanism for supplying nitrogen through their potential to harvest biologically fixed nitrogen to support both animal production and a subsequent phase of arable cropping. This bulletin answers some of the common questions about organic grassland management.

An integrated analysis of scale effects in alternative agricultural systems Organic Eprints
Firth, Chris; Philipps, Lois; Stagl, Sigrid; Benton, Tim; Brown, Katrina; Burton, Rob; Carver, Steve; Davies, Ben; Gibbon, David; Godwin, Bob; Kunin, Bill; Rigby, Dan; Salt, Steve.
The impacts associated with alternative methods of agricultural production, and the factors that drive their adoption, are critically dependent on the scale at which they are applied. Using organic farming as a case study, this project operating from 2006-2009 in the UK, will undertake an integrated assessment of scale effects by studying matched sets of farms situated in landscapes with high and low concentrations of organic farming.

Animal Health and Welfare in Organic Agriculture Organic Eprints
Philipps, Lois.
A brief report is given of the 4th Network for Animal Health and Welfare in Organic Agriculture (NAWHOA) workshop at Wageningen in the Netherlands, held in March 2001. The workshop focussed on breeding (especially dairy, pigs and poultry) and feeding, as opposed to yield and productivity, with the emphasis on food quality. Feeding was discussed from two angles: feeding for production, and feeding to protect the animal from disease or parasitic infection. A vision of the future was described, in which higher prices are gained for fewer animals, better housed and with a regional approach to breeding, processing and marketing.

Carrot or stick? – Would information concerning the economic value of nutrient losses, and their impact on food quality achieve greater environmental protection than regulation? Organic Eprints
Fowler, Susan M; Philipps, Lois; Watson, Christine A.
This report was presented at the UK Organic Research 2002 Conference. Organic standards have, since their origin (Soil Association 1967) required high standards of manure management, but in reality, these have not been implemented, possibly because of perceived costs of improved handling. However, a cost/benefit analysis of intermediate steps of nutrient conservation and manure handling may provide a practical solution, optimising retention of nutrients, financial and time inputs and environmental protection. Recent research on composting with conventional manures has quantified nutrient losses from heaps with different treatments (Parkinson et al, 2001). Financial and environmental costs and benefits of different management approaches are discussed.

Developing an Agro-forestry System for Production of a Commercial Organic Chicken Flock Focusing on Profits on a ‘Triple Bottom Line’ Organic Eprints
Aspray, Claire; O'Brien, Josie; Philipps, Lois.
In most modern free-range poultry systems birds do not fully utilise the range provided. Knowledge of the ancestral history of the domestic chicken, combined with research observations suggests benefits of agro-forestry systems for chickens. A commercial organic poultry agro-forestry system was developed for Sheepdrove Organic Farm, Berkshire, UK, affording the benefits of an agro-forestry system, whilst retaining commercial viability. Five avenues of highly diverse parallel hedges incorporating tree, shrub and herb species were planted. On-going monitoring of the system was put in place to evaluate its development. The programme consists of monitoring: 1) biodiversity 2) soil nutrient status and respiration 3) behaviour and welfare of the poultry....

Development of an agroforestry system for chicken production Organic Eprints
Philipps, Lois; Engel, Cindy; Wolfe, Martin.
This report was presented at the UK Organic Research 2002 Conference. Because conventional production of chickens has gone further than any other animal production system towards complete control of the animal’s brief lives, development of effective silvo-poultry systems seems particularly necessary for these essentially woodland birds. The objective is to develop a production system that closely matches the physiological and behavioural needs of the animals being reared. For the example of chickens, this means trying to mimic a woodland/forest-clearing environment. By providing a wide range of trees, shrubs and herbs, it should be possible to provide shelter, nutrition and medicinal benefits for the birds. At the same time, the system needs to fulfil...

Development of Cattle Housing for Sheepdrove Organic Farm Organic Eprints
Philipps, Lois; Clark, Fergus.
Housing criteria should be based around the fundamental concept that “the housing should be adapted to meet the needs of the animal and NOT the adaptation of the animal to meet the needs of the building”. In practice this means housing conditions that meet the needs of the animals in terms of their social behaviour, eg subdominant animals must have the opportunity to withdraw or avoid higher status animals. This may mean greater space at feeding and watering sites greater space per cow alley widths sufficiently wide to allow free passage and the avoidance of dead ends. Good husbandry skills and herd stability are also important. (3rd NAHWOA Workshop 2002) In order to achieve these criteria there are two areas under consideration, improvements to the...

Organic farming: technology transfer (Environmental impact and soil fertility) (OF0405) Organic Eprints
Shepherd, Mark; Pearce, Bruce; Cormack, Bill; Philipps, Lois; Cuttle, Steve; Bhogal, Anne; Costigan, Peter; Unwin, Roger.
This project covered two separate activities, but both were examples of technology transfer, relating to organic farming: 1. Developing a science-based report, which covered an assessment of the environmental impacts of organic farming. Defra’s Action Plan to Develop Organic Food and Farming included as Annexe 3 an assessment of the environmental impacts of organic farming. This paper was prepared by a Subgroup of the Action Plan for Organic Farming. Its purpose was to summarise the Subgroup’s views of the likely comparative effects of organic and conventional farming on the environment. However, to be robust and defensible, the assessment needs to be supported by scientific data. Although the report was based on such an assessment, the scientific...

Sheepdrove Organic Farm Soils Programme Report 2003 Interim Report Organic Eprints
Philipps, Lois.
Sheepdrove Organic Farm wishes to maintain or improve soil fertility (where appropriate) in accordance with organic principles and to gain a greater understanding of the biological activity with the soil ecosystems of the farm. In order to monitor changes in soil fertility a monitoring programme has been established to record all available past soils data and implement an ongoing programme that meets the agronomic needs of the farming enterprises and contributes to the ‘Sheepdrove Story’. From the limited data collected to date there is evidence that organic matter levels are higher than would be expected on these soil types and that past management has maintained major nutrient status at ‘conventional’ levels.

Soil Monitoring Programmes at Sheepdrove Organic Farm 2003-2004 Organic Eprints
Philipps, Lois.
Soil is a finite resource and is increasingly under pressure from a variety of human activities for example agriculture, construction and mineral extraction. However, for generations soil has been the basis for agricultural production, a raw material, which with sensitive management can be used year after year. Sheepdrove Organic Farm is striving to reach its goal, of developing a high quality food production system with adherence to strict policies of high animal health and welfare and increasing biodiversity and environmental benefits. Objective 1 is to implement a rolling soil analysis programme so that every year fields entering or leaving the fertility-building phase are sampled for soil nutrient status. The information gathered from this...

The Establishment of a Preliminary Weight Profile for the 257 Table Birds within the Sheepdrove Organic Farm Organic Silvo-Poultry System. Organic Eprints
Pegg, Venessa; Dyke, Kirstie; Philipps, Lois; Phillips, Scott; Pearce, Bruce.
A preliminary weight profile was produce for the organic silvo-poultry system on Sheepdrove organic farm. Seven batches (each of 20 hens and 20 cocks) were weighed over a two month period (January/February 2003). No current organic silvo-poultry weight profile was available but the weights achieved were found to exceed those of the nearest suggested profile (ISA 657) but were beneath the weights required for Sheepdroves markets. There was great and inconsistent variation between the batches and between sheds. This suggested that environment and management of particular houses could be having a large impact on final chicken weights.

The long-term agronomic performance of organic stockless rotations Organic Eprints
Welsh, James P; Philipps, Lois; Cormack, William F.
This report was presented at the UK Organic Research 2002 Conference. Two long-term experiments were established with the aim of evaluating the agronomic and economic performance of organic stockless rotations. In total, four different rotations were evaluated at two sites in the south (Elm Farm Research Centre) and east (ADAS Terrington) of England. All of the rotations included either a one or two-year red clover green manure crop to provide nitrogen for subsequent crops and it was found that this was sufficient to support three or four years of arable cropping. Over a period of eleven years at EFRC and five years at ADAS Terrington, there was no evidence of a decline in crop yield, although there were significant year-to-year variations. Crop yields...

Tools for managing manure nutrients Organic Eprints
Shepherd, Mark; Philipps, Lois; Webb, John.
Manures are a valuable source of nutrients (and organic matter), and can be seen as a method of transferring nutrients around the farm (for homeproduced manures) or as a method of importing fertility (imported manures or composts). Good manure management offers a ‘win-win’ opportunity: benefits to soil fertility and benefits to the environment (less pollution). This paper describes two tools for manure nutrient planning: the use of look-up tables to assess nutrient content, and the development of a Decision Support Tool for describing nutrient transformations during manure management.
