The Kalibokor drainase is a branch of the Kalimas River which passes Sukolilo District as the downstream. Sukolilo District is dominated by residential areas, educational areas, commercial areas and hospitals where some of the wastewater discharges directly to the Kalibokor drainase. The purpose of this study was to determine the watershed conditions of the mafcroinvertebrates types found using biologic method. This research is descriptive with a survey approach that identifies the biota of the Kalibokor drainase as an indicator of water pollution in Sukolilo District. Data analysis was carried out by starting with the identification of the obtained macroinvertebrates, then clasify biota become 2 groups, namely EPT (Ephemeroptera, Plecoptera, and Tricoptera) and non-EPT, then calculating the Water Pollution Index. The results showed that the Kalibokor drainase in Klampis Ngasem Village, Sukolilo District was included in the moderately polluted category

GülleBest : What low-emissions technology exists for the application of slurry and digestate?

Rund 95 % der Ammoniakemissionen in Deutschland stammen aus der Landwirtschaft, 40 % davon aus der Ausbringung von Wirtschaftsdüngern. Flüssige Wirtschaftsdünger enthalten hohe Anteile an Ammoniumstickstoff, der insbesondere im Kontakt mit der Atmosphäre schnell in gasförmiges Ammoniak (NH3) umgewandelt werden kann. Damit geht der Stickstoff den Pflanzen als wichtiger Nährstoff verloren. Der Luftschadstoff NH3 gefährdet nicht nur sensible Ökosysteme, sondern auch die menschliche Gesundheit.Around 95 % of ammonia emissions in Germany come from agriculture, 40 % of which from the application manure. Manure generally contains high amounts of ammonium nitrogen, which can be rapidly transformed into gaseous ammonia (NH3), especially upon exposure to the atmosphere. The nitrogen is thus lost to the plants as an important nutrient. The air pollutant NH3 not only endangers sensitive ecosystems, but also human health
