The paper presents analysis of soil spatial distribution and productivity of Populus x euramericana I-214 forest cultures in forest management unit (hereinafter: FMU) Muzljanski rit. Soil cover in the FMU is heterogeneous in relation to position and altitude in floodplain. Analysis were conducted on eugley and humogley soil types. Eugley, soil type, was delineated according to physiologically active soil depth as α, β or β/γ gley soils and humogley was delineated as one soil unit. Cultures of the poplar clones Populus x euramericana I-214 are found on at least two but usually more different site types within the same forest management section (18.43 %). Single forest management section is a by definition a single forest spatial unit having similar ecologic factors. Aim of our research was to enable consistent forest section delineation, based on the interaction of soil productivity properties and distribution as well as Populus x euramericana I-214 productivity dataset. Based on our anaysis (spatial analysis of raster layers of soil systematic unit distribution-soil subunit, digital elevation model and productivity according to inner delineation of FMU Muzljanski rit), the resuts show eugley share in lower systematic soil unit. The results show contribution of lower systematic units of eugley in forest managemet section/culture. We found a raising trend of α and β-gley, as well as humogley. On one side the higher contribution of this sistematic units indicates reduction in the forest culture yield. On the other side higher contribution of β/γ gley indicates an increase of culture yeald. The Populus x euramericana I-214 cultures are spatialy concentrated, extending over soil units with different characteristics, pointing in alternative economicaly justified section delineation, based on the soil types.

Abstract Shortleaf pine (Pinus echinata Mill.) is the most ecologically and economically important tree species in the Ouachita Highlands of the southcentral United States. This species can occur in relatively pure stands but most frequently exists in mixed stands with various hardwood species. Because of the diversity of land ownership, public concerns about forest management, and increased intensity of forest practices, the Ouachita Highlands have been a focal point for numerous research projects over the past 20 yr that have studied how forest management affects soils. We summarized information in four fundamental areas: (1) compaction, (2) soil loss, (3) organic matter, and (4) nutrients to better evaluate if and to what degree management practices such as harvesting and prescribed fire modify the productivity and sustainability of soils in this region. The review indicated that soils with less than 15% rock content or sandy loam textures were susceptible to compaction when harvested during wet weather conditions. Although partial harvesting techniques, such as single-tree or group selection, tended to reduce overall soil disturbance in a stand, it increased soil compaction on primary skid trails by concentrating traffic on fewer skid trails. Compaction on skid trails frequently elevated bulk density to levels that could reduce regeneration success or seedling growth. Using current harvesting systems, soil losses and displacement to streams after harvesting appeared to have little or no effect on long-term soil productivity. Harvesting and prescribed fires significantly altered nutrient and organic matter contents of the forest floor and mineral soil. However, recovery of these nutrient or organic pools often occurred rapidly after these cultural practices occurred. Little information was available for determining how repeated silvicultural practices over multiple rotations would affect long-term soil productivity in the Ouachita Highlands. South. J. Appl.

Trends over the past 25 years indicate that Argentina’s growth in its grain crop productivity has largely been supported by the depletion of the extensive fertility of its Pampean soils. Long-term research provides insight into sustainable nutrient management strategies ready for wide-scale adoption.

The natural conditions, climate change and socio-economic challenges related to the transformation from a socialistic society towards a market-driven system make the implementation of sustainable land management practices in Mongolia especially complicated. Forests play an important role in land management. In addition to providing resources and ecosystem functions, Mongolian forests protect against land degradation.We conducted a literature review of the status of forest management in Mongolia and lessons learned, with special consideration to halting deforestation and degradation. We grouped our review into seven challenges relevant to developing regionally adapted forest management systems that both safeguard forest health and consider socio-economic needs. In our review, we found that current forest management in Mongolia is not always sustainable, and that some practices lack scientific grounding. An overwhelming number of sources noticed a decrease in forest area and quality during the last decades, although afforestation initiatives are reported to have increased. We found that they have had, with few exceptions, only limited success. During our review, however, we found a number of case studies that presented or proposed promising approaches to (re-)establishing and managing forests. These studies are further supported by a body of literature that examines how forest administration, and local participation can be modified to better support sustainable forestry. Based on our review, we conclude that it is necessary to integrate capacity development and forest research into holistic initiatives. A special focus should be given to the linkages between vegetation cover and the hydrological regime.
