It is observed increasing of abandoned land in Poland in last decade of 20th century. The part of abandoned land is usually covered by birch tree community. The entrance of birches, especially on pure sandy area, changes properties of soil. The samples of soil horizons, litter in different stages of decomposition and leaves from birch trees, were taken into analysis. The role of birch was analysed also in comparison to arabie land, abandoned land without trees and different ages birch trees communities. After the entrance birch trees soil profiles were enriched in nitrogen and elements such as aluminium, iron, cadmium, lead, cobalt, zinc, which were moved from soil or come from atmospheric load and were accumulated in litter or humus horizon. Compared to arabie land, some elements (for example calcium) had lower concentration under birch trees. After several years without fertilization the relationship between elements were changed. In early stages (until 10 years) in litter horizons potassium prevails calcium, later - calcium prevails potassium . Birch trees made soil environment more natural compared to arable land.

Agroforestry is a type of farming that integrates agricultural crops with trees, and is a way of managing the land in which crop and livestock production coexist in the same area with woody plants and/or shrubs. Agroforestry promotes efficient use of soil and environmental resources compared to monoculture farming. The integration of trees in agroforestry improves the fertility and physical, biological and chemical properties of the soil, and consequently food, timber and fodder. Such cultivation promotes an appropriate microclimate by influencing soil properties and moisture content. Integration of trees on agricultural land provides additional climate and environmental benefits and can be a cost-effective and climate-friendly practice. The article identifies native coniferous forest tree species that could potentially be part of agroforestry crops with a view to their use in functional foods.

Agroleśnictwo to rodzaj upraw integrujący uprawy rolne z drzewami i jest sposobem gospodarowania ziemią, w którym produkcja roślinna i zwierzęca współistnieje na tym samym obszarze z roślinnością drzewiastą i/lub krzewami. Agroleśnictwo sprzyja efektywnemu wykorzystaniu zasobów glebowych i środowiskowych w porównaniu z uprawą monokulturową. Integracja drzew w uprawie rolniczej poprawa żyzność i właściwości fizyczne, biologiczne i chemiczne gleby, a w konsekwencji żywności, drewna i paszy. Taka uprawa sprzyja odpowiedniemu mikroklimatowi wpływając na właściwości i wilgotność gleby. Integracja drzew na gruntach rolnych zapewnia dodatkowe korzyści dla klimatu i środowiska, dlatego może stanowić opłacalną i przyjazną praktykę. W artykule wskazano rodzime gatunki iglastych drzew leśnych, które potencjalnie mogłyby stanowić element upraw agroleśnych z uwzględnieniem ich wykorzystania w żywności funkcjonalnej.

This article attempts to analyze ethnographically the species of trees, whose names have not been mentioned in the collection of folksongs originating in Warmia and Mazury edited by Marian Sobieski. From the ethnographical point of view and with respect to the natural environment, they seem to be the most valuable plants in the region. The research falls within the framework of studies called “absence figure” that are currently popular and has been conducted on the premises of the theory of bioregionalism. Bioregionalism assumes a particular relationship between the world of plants and humans, their tradition, habits and culture. Accordingly, some species of trees, such as spruce, pine, juniper, birch-tree, and willow have been examined and analyzed. The description of each includes examples of main dialect variations of plant names, information about the place occupied by each species in the natural habitat of Warmia and Mazury and the role it played in the material heritage of local inhabitants. The conducted research allowed the author to determine the reason for the absence of key tree species. The cause (in everyday life and the sacrum sphere as well) might have been the specificity of the discussed anthology, the frugality of artistic devices in the songs or changes in the structure of tree stands.
