Popis: Under laboratory conditions, seepage of liquid cattle manure with dry matter content of 3-8% through subsoil was studied in relation to its dry matter content and period of storage. Statistical dependence of the total amount of eluate on the dry matter has been found (P = 0.0013). A hypothesis was also confirmed that liquid cattle manure shows a sealing effect during storage. It was found that the average value of coefficient of permeability decreases as soon as 48 hours after the start of storage under the value 5.56171 × 10-6 cm.s-1, which, according to peer reviewed literature, is not hazardous to the environment. The results will help in designing projects of liquid cattle manure reservoirs and assessment of their effect on the environment.
