Assessing quality of plant raising media for organic systems Organic Eprints
Little, Tony; Morris, Cath; Clarke, Aldwyn.
Good quality transplants are vital to growers for a number of reasons. Their ability to better tolerate pest, disease and weed problems and their capacity to make better use of newly incorporated green manures (compared to direct drilling) make them all the more so in organic systems. The availability of high quality growing media is essential to producing healthy vigorous plants, but the organic standards restrict the choice of products available and many growers do not feel they have sufficient information to base their choices. OCW, with support from Farming Connect, coordinated a project to assess the certified products and looked at a green waste based product under development to help address this problem. Growers were supplied with samples of...

The inclusion of diatomaceous earth in the diet of grazing ruminants and its effect on gastrointestinal parasite burdens Organic Eprints
McLean, Barbara; Frost, David; Evans, Eifion; Clarke, Aldwyn; Griffiths, Bernard.
Two studies were carried out to assess the efficacy of diatomaceous earth as an alternative to anthelmintics in grazing ruminants. Animals treated with anthelmintics and groups of untreated animals were included for comparison. Cattle and sheep which received the diatomaceous earth supplement had low Faecal Egg Counts (FEC) for the duration of the experimental period, similar to animals in the anthelmintic groups. Inclusion of diatomaceous earth in the diet of grazing ruminants may offer some benefits in controlling internal parasites.

Organic tree propagation under Welsh nursery conditions Organic Eprints
Frost, David; Clarke, Aldwyn.
The demand for organically raised tree and hedging plants had been reported from organic farmers in Tir Gofal, as well as within the landscaping industry. Although there are a number of plant raising nurseries producing organically raised plants for vegetable and fruit production, there are no tree nurseries producing to organic standards. Nursery tree growers were concerned that there was currently too little known about the performance of tree seedlings in organic substrates (e.g. in root-trainers), nor about the nutrient supply to seedlings under organic regimes, nor about diseases control (especially fungal diseases such as mildew). Therefore, the development of three hedging species; Hawthorn, Hazel, Blackthorn, were tested for two growing systems in...
