The campaign “Living soil” (“Dzīvā augsne”) implemented within the project GrassLIFE by the Institute of Environmental Solutions has ended.
The excavation of the bags took place from 15 August to 15 October – the time of excavation depended on the date on which the participants dug the bags in. Once dug up, the tea bags were dried and weighed. The change in the weight of the bags was the main indicator of the biological activity of the soil – the greater the loss of the tea weight, the more active the organisms living in the soil and the decomposition processes.
In total, the biological activity of the soil was studied in 140 different grasslands throughout Latvia – meadows, pastures, lawns.
