The effect of lignite on nitrogen loss, odour and water activity in broiler litter
The loss of nitrogen from broiler litter poses an environmental risk and represents the forfeiture of a nutrient with considerable economic value. Odour is also generated during broiler production, which can be a nuisance to neighbouring residents, resulting in complaints and regulatory action. Both nitrogen loss and odour are closely linked to litter water activity. Lignite is well known for its adsorptive properties due to its rich surface chemistry and microporosity, which may mitigate these issues when applied to animal bedding material. This research aims to investigate lignite’s capacity as a litter amendment to reduce N loss, odour and water activity in broiler litter. We hope to increase the nitrogen value of organic waste, improve the recycling of nutrients and develop a scalable bio-fertiliser.
