T1 - Development of soil physical parameters on initial landforms - An example from a post-mining recultuivation site in Lusatia, East Germany T2 - AGU Fall Meeting Suppl. N2 - Recultivation efforts in mining areas attempt to regenerate soils and landscapes for various land use options and create initial conditions which are beneficial for the development of the future ecosystems. On very young landforms physical and chemical properties of soils play a major role for the further evolution of the developing ecosystem as well as the landforms itself. Less is known about the very first alterations of physical parameters in accordance to different land uses and recultivation practices. Our study deals with the agricultural recultivation of post lignite mining areas in Lusatia, East Germany. The sandy substrate used for recultivation stems from depths of several meters and is therefore free of recent soil organic matter. The substrate itself is unstructured. After it has been excavated and transported on conveyor belts to the recultivation site, it is piled up to dams of a height of 1-4 m and levelled off with heavy crawlers. During these processes the substrate is subjected to strong mechanical stresses. This practice induces compaction which causes decreasing yields of agricultural crops to a certain extent. In this context we are investigating the effect of different organic soil additives in combination with different recultivation crop rotations on the development of soil structure for improved agricultural land use. Our experimental site has recently been heaped up and levelled off. On the 25 experimental sub areas 2175 undisturbed soil samples were taken out of three soil depths to characterize initial physical properties before any recultivation measures have been applied,. We present laboratory results of this status-quo sampling. The results indicate that the site is very heterogeneous in terms of mechanical stability, bulk density, total pore volume, saturated hydraulic conductivity and air permeability. Moreover, our results show that bulk density is not an appropriate parameter to derive soil functions, e.g. permeability or stability. Additionally we found that even in areas of bulk densities > 1.8 g/cm3 and with an inclination < 2 % impressive run-off and gully erosion developed during heavy rainfall events. We conclude that initial processes altering soil physical parameters play a major role for the landform evolution within the first 12 months after dumping. Further studies should reveal the mid-term impact of organic additives on the soils after 7 yrs.

The aim of the project was to monitor abiotic and biotic parameters of forest regrowth under different management regimes on former wildfire sites in northeastern Germany. The observations comprised intermittent and continuous measurements or surveys on meteorological parameters (rainfall, temperature, vapour pressure deficit), soil (soil type and texture, soil chemistry and leaching, water content, soil temperature), deadwood, stand structure, vegetation regrowth, abundance of selected fauna (moths, beetles, mammals), UAV-based remote sensing (stand structure, spatial overview), and photo monitoring (succession). Thus, the multitude of collected data allows not only for detailed analyses of these observables separately, but also considering their interaction for a more multidisciplinary view on forest recovery after a wildfire.

Hemp cultivation, due to rapid growth and high biomass production, in addition to its deep-seated and entrenched roots, has vast potential in carbon (C) sequestration and nitrogen (N) accumulation. The research aims to analyse industrial hemp species Santhica 27 feasibility for fiber cultivation and biomass production in water-scarce and nutrient-deficient sandy soils of Brandenburg. The impact of high (142 plants·m− 2) and low (71 plants·m− 2) planting densities on hemp´s morphological development and productivity, expressed as yields, is also assessed. The results showed that the dry condition with a water deficit of 168.9 mm during the growing period was the main factor significantly impeding hemp`s morphological development and fiber yields. Control treatments with the precipitation sum of 242 mm planted in a lower planting density had on average, significantly taller plants of 122 cm with greater total biomass yield of 3.74 t·ha− 1 dry weight compared to simulated water-scarce dry treatments, with the lowest plant height and total biomass of 69 cm and 1.91 t·ha− 1, respectively, when planted in high density. Although the N content in the original sandy soil was below 1 g·kg− 1, the dry environmental conditions had prompted N accumulation up to 35 N g·kg− 1 in hemp biomass, 18 N g·kg− 1 in lateral roots, and 13 N g·kg− 1 in tap roots. High calcium (Ca) content was found in hemp biomass and lateral roots, whereas potassium (K) content was greater in tap roots. The results suggest that a lower hemp planting density for hemp cultivation should be considered in a water-scarce and nutrient-deficient environment. Moreover, the elemental analysis showed that hemp parts contain considerable amounts of macronutrients, which could be of great importance to the sandy soil´s total nutrient-pool enrichment.

T1 - Intensive post‐fire management drives ecosystem degradation but does not prevent tree regeneration T2 - Journal of applied ecology N2 - In recent years, wildfires have affected relatively large areas of managed forests in Central Europe. Often, forestry uses intensive post‐fire management practices, which can have negative effects on various components of the ecosystem. Fire ecology has been largely neglected in Central Europe and strategies for appropriate management and successful reforestation of burned areas are urgently needed. We have studied the effects of different post‐fire forest management treatments (including different levels of salvage logging and soil disturbances such as ploughing or raking) on soil parameters (phosphorus, nitrogen, calcium, potassium, magnesium, pH), microclimate (temperatures, vapour pressure deficit (VPD), heat and drought stress), deadwood, regrowth (biomass of tree regeneration, herb and bryophyte layer) and species richness (plants and saproxylic beetles) 3 years after wildfire in a Central European Scots pine forest (northeast Germany). Intensive forest management led to more unfavourable abiotic conditions, including stronger temperature extremes and elevated VPD. Consequently, vegetation on these sites experienced increased heat and drought stress and reduced nutrient availability. The biomass of the herb and bryophyte layer, as well as the species richness of plants and saproxylic beetles, was lower on completely salvage logged sites. Tree biomass recovered on all sites, including sites with intensive forest management. Tree regeneration in our study area was mainly driven by the recolonization of the pioneer species European aspen (Populus tremula), which can tolerate a wide range of site conditions. Synthesis and applications. We recommend avoiding intensive management on burned sites, such as complete salvage logging or ploughing, as this creates extreme site conditions that could inhibit the regeneration of more sensitive tree species and result in a long‐term legacy of degradation. In addition, herb and bryophyte layers, as well as the species richness of vegetation and saproxylic beetles, which are important components of forest ecosystems, are negatively affected by intense forest management.
