Work summarizes the ash utilization opportunities. Five different ash and liquid manure mixture forms were researched and evaluated using the Technical (LLU) faculty-owned equipment. Master Thesis was carried out to create a new fertilizer production equipment, as well as to provide insights to...

In the recent years a common forest management practice has been to leave a certain number of living trees in clear-cuts. The so-called retention trees may ensure survival of epiphytic bryophytes and lichens after tree harvest. In this study, the goal was to determine the occurrence of epiphytic...

Productivity and response to waste water, wood ash and digestate fertilizer of commercial clones 'Sven', 'Gudrun', 'Tordis', 'Tora', 'Lisa', 'Inger', 'Stina' and 'Klara' were tested in Skriveri and "Vecauce". The best combination of moisture content of chips and productivity showed 'Sven'...

The objective of the study is finding out the interrelations of estimation values necessary for modeling the yield of grey alder stands.
