| Numbers of faecal microbes (faecal coliforms, enterococci, sulphite-reducing clostridia and coliphages) were determined in run-off waters from cattle farms in 1998-2005. Water samples were collected from drain wells and open ditches adjacent to exercise yards and forested feedlots for cattle, a grass field with slurry applications and a pasture with buffer strips. The indicator numbers were the highest in run-off waters from asphalt exercise yards while the figures were even 100-fold smaller in waters from a bark covered yard. In the forested feedlots, where cattle were fed for the winter months or all the year round, the indicator numbers were as high as the ones in a grass field with slurry applications or a pasture. There was a severe risk of... |

| The fertilizer value of human urine was compared with mineral fertilizer in pumpkin (Cucurbita maxima) cultivation at a dose of 113 kg N ha-1 with no-fertilization used as control. The growth of the vine was better in urine fertilized pumpkins than in mineral fertilized and non-fertilized pumpkins. Total fruit biomass was higher in mineral fertilized plants compared to urine fertilized and non-fertilized pumpkins. Urine fertilized pumpkins may have suffered from lower potassium or higher chloride, thus they produced fewer flowers and fruits. However, total fruit biomass and the number of fruits were slightly higher in urine fertilized plants than in their non-fertilized counterparts, i.e. 17.2 t ha-1 more pumpkin could be produced with urine fertilizer.... |

| The yield of carrots by horse manure was 66 % higher than the yield with artificial fertilizer. The yields of other plants fertilized with composted horse manure or artificial fertilizer were equal. The yields of plants fertilized with cattle manure were clearly lesser. The taste of lettuces fertilized with artificial fertilizer was assessed to be the sweetest and the cattle manure fertilization the less sweet. Potato fertilized with horse manure was assessed significantly tenderer at structure than with other fertilizers. Triangle tests showed no significant differences in tastes of other vegetables between fertilizations. Hygienic quality of vegetables fertilized with horse manure or artificial fertilizer was excellent. Small amounts of faecal... |

| Two exercise yards have been designed, constructed and monitored. Samples from the runoff water have been taken regularly, and their nutrient concentrations(nitrogen, phosphor), total solids, pH, total chemical oxygen demand and hygienic quality have been analysed. The behaviour of animals has been observed. |
