Faeces and its utilisation as soil conditioner
One person produces appr. 100–200 g of faeces per day, the dry matter content
of which is about 20%. Human faeces contain very rich ecosystems of versatile micro-organisms. Bacterial numbers such as 1010/g have been presented (Ketchum 1988). In addition, there are high numbers of viruses, protozoa and fungi. These micro-organisms are strictly or facultatively anaerobic and many of them cannot be cultivated. Thus the numbers presented are not at all accurate and microbiological numbers vary according to diet; moreover the microbial distribution in faeces is very uneven.
