Uittreksel
Organic farmers are used to applying animal manure from different origin, and the recycling of this manure is needed to close nutrient cycle as much as possible. Improving manure product quality is another possibility to facilitate organic manure to find its way from one organic farm to another. Chicken manure is a nutrient-rich fertilizer that ought to be applied in moderate doses, which is difficult in practice. Composted chicken manure may be particularly suited for organic vegetable production. Chicken manure is less attractive for application on soils rich in available phosphorus (P) due to its low nitrogen (N)/P ratio. Combining chicken manure and a carbon-rich feedstock for co-composting or temporary storage may overcome these disadvantages and may reduce nutrient and particularly N losses during storage and after application. Goat manure from a deep litter housing system has a high carbon (C)/N ratio and its decomposition can be enhanced by mixing the stockpiled material several times. The microbial decomposition process will probably favour
nutrient availability after field application. The heating in the stockpile may also counteract the survival of parasites and pathogenic bacteria. Our objective was to evaluate the fertilization value of compost and manure of different quality using a dosage as limited by the future P input standard of 55 kg ha-1 year-1, for vegetables.
