Short summary
The summertime thaw depth of permanently frozen ground (active layer thickness, ALT) is of critical importance for natural hazard management (e.g., rock avalanches) and construction (foundation stability) in mountain permafrost regions. We report the first analytical heat transport model for simulating ALT based on near-surface temperature in permafrost rock walls. Our results show that the ALT will likely increase by more than 50 % by 2050 at 3000 m a.s.l. in the European Alps.

Legumes constitute up to 50 % of all crops in organic rotations surrendering these susceptible towards a range of soil-borne pests and diseases. We investigated how plant-parasitic and other free-living trophic nematode guilds are affected by four diverse organic farming types. The Mixed Farm type (50 % legumes in the rotation) harbored the highest numbers of nematodes of all farm types. Pratylenchus was the most abundant genus and built-up large populations during the clover grass ley period.

Crop rotations with legumes and use of organic and mineral fertilizers show potential to reduce agricultural N losses. This study examined N losses, including direct N2 flux, on two adjacent sites with different management histories: organic farming (OF) with legume cultivation and integrated farming (IF) using synthetic and organic N inputs. IF increased soil organic carbon and nitrogen content and 15N recovery and showed a balanced N budget (i.e. more efficient N cycling compared to OF).

Pedotransfer functions (PTFs) are used to predict parameters of models describing the hydraulic properties of soils. The appropriateness of these predictions critically relies on the nature of the datasets for training the PTFs and the physical comprehensiveness of the models. This roadmap paper is addressed to PTF developers and users and critically reflects the utility and future of PTFs. To this end, we present a manifesto aiming at a paradigm shift in PTF research.

Measurements of soil water retention properties play an important role in a variety of societal issues that depend on soil water conditions. However, there is little concern about the consistency of these measurements between laboratories. We conducted an interlaboratory comparison to assess the reproducibility of the measurement of the soil water retention curve. Results highlight the need to harmonize and standardize procedures to improve the description of unsaturated processes in soils.

Important topics in land–atmosphere feedback research are water and energy balances and heterogeneities of fluxes at the land surface and in the atmosphere. To target these questions, the Land–Atmosphere Feedback Observatory (LAFO) has been installed in Germany. The instrumentation allows for comprehensive measurements from the bedrock to the troposphere. The LAFO observation strategy aims for simultaneous measurements in all three compartments: atmosphere, soil and land surface, and vegetation.

We analysed the evolution of model parameter uncertainty and prediction error as we updated parameters of a maize phenology model based on yearly observations, by sequentially applying Bayesian calibration. Although parameter uncertainty was reduced, prediction quality deteriorated when calibration and prediction data were from different maize ripening groups or temperature conditions. The study highlights that Bayesian methods should account for model limitations and inherent data structures.

Short summary
Presented are measurement results from six agricultural fields operated by local farmers in southwestern Germany over 9 years. Six eddy-covariance stations measuring water, energy, and carbon fluxes between the vegetated soil surface and the atmosphere provided the backbone of the measurement sites and were supplemented by extensive soil and vegetation state monitoring. The dataset is ideal for testing process models characterizing fluxes at the vegetated soil surface and in the atmosphere.

Short summary
Arable soils emit or absorb greenhouse gases such as carbon dioxide, nitrous oxide and methane. This study compared two gas analysis techniques for determining greenhouse gas fluxes under field conditions using the closed chamber method. Fluxes were measured simultaneously using the widely applied gas chromatography (GC) and the emerging mid-infrared laser absorption spectroscopy (LAS) technique. Our results showed that LAS is a reliable alternative to GC, particularly for low flux rates.
