Handbook for Composting and Compost Use in Organic Horticulture Organic Eprints
Alsanius, Beatrix W.; Blok, Chris; Cuijpers, Willemijn J.M.; França, Soraya C.; Fuchs, Jacques G.; Janmaat, Leen; Raviv, Michael; Streminska, Marta A.; Termorshuizen, Aad J.; van der Wurff, André W. G..
Compost, as a product of recycling processes, can be a very appropriate input material for organic farming, provided the composting process is well-managed, the input materials are free of contaminants, and the resulting product is applied according to the system’s ecological needs. Compost is a very important input material for organic greenhouse production. Organic greenhouse production may vary in the level of intensity, but it is generally a system with high turnover rates of organic matter, high inputs of both nutrients and energy, and high production levels. Compost is used as an important source of organic matter and nutrients in greenhouse horticulture, and is an important component of growing media for nurseries. Compost plays an important role in...

An Overview of Phytosanitary Risk Aspects of Composting by Organic Farmers Organic Eprints
Termorshuizen, Aad J.; Blok, Wim J..
Usage of compost in agriculture always brings about the risk of introducing plant pathogens. By proper composting, resulting in high temperatures during the thermophilic phase, compost can be applied safely. Organic farmers often prefer to compost organic residues themselves. The advantage of such an approach is that no material of foreign origin is introduced, but a drawback is the smaller scale of composting, which brings about greater phytosanitary risks. These risks can be dealt with by increasing the composting duration and by proper turning of the compost heap. If only organic residues from farms are composted, this usually results in low-quality composts because of the low lignin contents. Therefore, addition of materials that are high in lignin,...

Disease suppression of potting mixes amended with composted biowaste Organic Eprints
Blok, Wim J.; Termorshuizen, Aad J.; Coenen, Trudie G.C.; de Wilde, Vinnie; Veeken, Adrie H.M..
Peat mining destroys valuable nature areas and contributes to the greenhouse effect. This warrants the search for alternatives for peat in potting mixes. Composted biowaste could provide such an alternative. An additional advantage of (partially) replacing peat by compost is the increased disease suppressiveness. In this study, nine commercial composted biowastes were tested for disease suppressiveness using the pathosystems Pythium ultimum-cucumber, Phytophthora cinnamomi-lupin and Rhizoctonia solani-carrot. Increased disease suppression was found in compost-amended potting mixes for all three pathosystems. The level of disease suppression ranged from slight stimulation of disease to strong suppression. Suppressiveness against one disease was not well...
