The burning of wood in the Bieszczady Mountains (SE Poland) began to play a significant role with first settlements in this region in the 17th and 18th centuries. Large beech wood resources were the main reason for such a high charcoal production in this part of Poland. The role of charcoal production in the Bieszczady region is reflected in the names of villages such as Smolnik (Tar), Potasznia (Potash)...
Oak decline phenomenon has been observed in Poland in the 1980s. Especially, Krotoszyn Forest District was affected in the years 1982−1984, when oaks were dying in a mass extend causing economic and ecological problems. Twenty five years later many Phytophthora species were isolated from rhizosphere soil suggesting their important role in fine root damage. This research was focused on application...
The paper presents the literature review concerning the general assumptions of the Data Envelopment Analysis (DEA) and its applications in forest management and wood industry evaluation. So far, efficiency evaluation in forestry sector was carried out using mostly the ratio analysis only. The DEA approach, which was developed in the 1970s, is based on the mathematical programming algorithm and gives...
Physical and chemical properties of biochar from wood biomass indicate that it can be a valuable supplement to nursery substrates, mainly to improve sorption capacity as well as nutrient and water retention. The paper presents the results of a pilot experiment on the impact of biochar on the moisture content of peat moss substrate and its retention properties. The experiment was carried out in the...
