| A project entitled “100% Organic Livestock Feeds – Preparing for 2005” looking at the implications for organic farmers of the removal of the current derogation to use a percentage of non-organic livestock feeds. 1) Researching the required volume of feed stuff, in particular protein crops, and potential for feed production within Wales. 2) Researching the suitability of alternative protein sources, and evaluating livestock systems regarding the potential for a reduction in energy and protein levels. 3) Proposing strategies for the development and stimulation of the industry. |

| The EU regulation requiring organic farmers to use 100% organic herbage seed is looming closer. Currently they are ‘enjoying’ a derogation from this because suitable seed is not available. For 2004 seeds mixtures had to contain at least 50% organic seed. This breathing space before full 100% organic seed is required is giving the organic industry time to improve the availability of suitable species and varieties. Historically there was a viable herbage seed production industry in the lowland and southern areas of Wales. This area turned to livestock production during its more profitable periods, with specialist arable and herbage seed production switching largely to south east England. The agronomic potential remains in Wales but now needs to be developed... |

| As costs for mineral fertilizers rise, legume-based leys are recognised as a potential alternative nitrogen source for crops. Here we demonstrate that including species-rich legume-based leys in the rotation helps to maximize synergies between agricultural productivity and other ecosystem services. By using functionally diverse plant species mixtures these services can be optimised and fine-tuned to regional and farm-specific needs. Field experiments run over three years at multiple locations showed that the stability of ley performance was greater in multi-species mixtures than in legume monocultures. In addition, mixing different legume species in the ley helps to suppress both early and late weeds. Further, combining complementary phenologies of... |

| This report describes the attitudes of converting and conventional producers in England to organic production. In 2000, a telephone survey was conducted of farmers in three groups: those who were converting, those who had contacted OCIS but decided not to convert, and a random sample of conventional farmers. The majority of converting farmers gave concerns about agrochemicals and fears about the future profitability of conventional farming as their main reasons for going organic. Marketing was not seen as an obstacle to conversion. Conventional farmers thought that advice and information on organic production were easily obtained, but converting farmers did not agree, suggesting that there was a shortage of more advanced knowledge. Non-converters gave... |

| Legume-based leys offer multiple benefits to ecosystem service provision, e.g. protecting soil and supporting pollinators. While weeds can play an antagonistic role during ley establishment, little is known about weed communities in these leys or about the optimal solutions for weed control in the establishment phase. To determine if the choice of ley species affects weed levels, we conducted field trials at six locations in the UK, measuring weed cover and biomass in monoculture plots of 12 legume and 4 grass species, plus an all species mix over two years. In these trials and in additional on-farm trials, weed cover and diversity were lower in the second than in the first year, owing to a decrease of annual weeds over time. The ability of a diverse... |

| Pest and diseases can have a significant effect on the establishment, yield and longevity of grass and forage crops. This tool is an atlas for the identification of the main pests regarding grass and forage crops. It has been written for Wales climates and it is not specific for organic farming. Nonetheless, the information contained, can be used by farmers, conventional or organic, skilled or newcomers, all over Europe. Besides pest descriptions, with pictures that facilitate the task of identification, it provides useful hints on preventive, non-chemical, practices to reduce pest incidence. |

| Organic Centre Wales (OCW) was originally formed to act as an information source for producers enquiring into organic farming; in our second phase, in response to changes in the sector, we have an increased remit on policy issues. It has been a busy time, seeing the production of a second Organic Action Plan, the implementation of the CAP reform and development work on agri-environment reforms. The year also saw the start of organic maintenance payments for farmers. This Annual Report contains accounts of the progress that has been made on many fronts during the last 12 months, particularly in market knowledge due to the research for the recently published report, 'Organic Food: understanding the consumer and increasing sales'. This information,... |
