Abstract: 
Leachates from differently covered cattle manure heaps amount to 88.7-117.4 l/m3 within 177 days, nitrogen leakage to 89.0-119.0g, respectively. A total protection against precipitation with plastic foil led to the lowest quantity of leachates indeed, but not to the lowest nitrogen leakage. During the first decomposition period no rain fell, but the quantities of leachates as well as the leakage of nitrogen were highest. After 20 days (11,7 %) of the experimental period) already 55.0-81.3 % of total leachates and 71.2-87.0 % of total nitrogen leakage were found, but only 1.7 % of the precipitate, fallen within 177 days. This clearly shows, that only the covering of manure heaps can not be sufficient either to reduce liquid leaching or nitrogen leakage significantly.
