Short summary
ET0vert is a process-based model concept for evapotranspiration of green walls, validated with onsite lysimetry data. Best accuracy of predictions is achieved using input data measured onsite and considering height dependencies of radiation, wind and VPD. If only remote climate station data is available as input, it must be “verticalized”. The model predicts the hourly and daily evapotranspiration necessary for e.g., irrigation planning, building energy simulations or local climate modeling.

This study proposes a model to predict soil hydraulic properties (SHPs) of constructed Technosols for urban greening. The SHPs are determined by the Technosol composition and describe their capacity to store and supply water to plants. The model predicts SHPs of any binary mixture based on the SHPs of its two pure components, facilitating simulations of flow and transport processes before production. This can help create Technosols designed for efficient urban greening and water management.

The adverse effect of microplastic (MP) on soil biota and soil structure depends on MP particle size and surface characteristics. Since weathering plays a major role in the genesis of these, it must be considered in both the analysis of environmental MP and the production of artificial MP for laboratory experiments. This work integrates recent findings on adverse effects and the genesis of its surface characteristics and discusses how to reproduce them to obtain closer-to-nature designer MP.

Short summary
Ultrasonication/density fractionation is a common method used to extract particulate organic matter (POM) and, recently, microplastic (MP) from soil samples. In this study, ultrasonic treatment with mechanical stress increasing from 0 to 500 J mL−1 caused comminution and a reduced recovery rate of soil-derived POMs but no such effects with MP particles. In consequence, the extraction of MP from soils is not affected by particle size and recovery rate artifacts.

Laboratory experiments that assess microplastic (MP) impact on the terrestrial environment require information on common soil MP concentrations. We reviewed item numbers and mass concentrations recorded in 23 studies, with 223 sampling sites in total with respect to the underlying entry pathways, land uses and vicinities. Common values included amounts of up to 13 000 items kg−1 and 4.5 mg kg−1 dry soil. Based on the collected data, we identified problems in past field studies.

Short summary
Via anthropogenic input, microplastics (MPs) today represent a part of the soil organic matter. We analyzed studies on passive translocation, active ingestion, bioaccumulation and adverse effects of MPs on multicellular soil faunal life. These studies on a wide range of soil organisms found a recurring pattern of adverse effects on motility, growth, metabolism, reproduction, mortality and gut microbiome. However, the shape and type of the experimental MP often did not match natural conditions.

To improve our understanding of the effects of tree species selection and management intensity on dissolved organic matter (DOM), we studied solution samples along the water flow path through forests with spectroscopic methods and biodegradation tests. There are distinct changes in DOM composition and biodegradability following the water path. Aboveground DOM was influenced by tree species selection but not by management intensity. Differences became aligned in mineral soil.

We tested a current theory, which proposes an upper limit for organic carbon (OC) stocks independent of increasing carbon input for a soil with already large OC stocks. The soil received a large additional carbon input as sawdust. In response, only the OC stock in 25–50 cm depth increased significantly. We assume, that due to saturation in 0–25 cm, added OC migrates downwards and becomes retained in 25–50 cm. This indicates the possibility to sustainably increase already large OC stocks further.

Microbial communities play a role in soil aggregate formation. However, the influence of the microbial community structure on POM occlusion within soil aggregates is still unproved. In this experiment, sterile sandy agricultural soil was incubated in two variants – inoculated with soil extract and infected with air-born microorganisms. After 76 days of incubation soils show a strongly differing microbial populations structure, but no significant difference in POM occlusion.

Short summary
Soil aggregate stability and POM occlusion are integral markers for soil quality. Besides physico-chemical interactions, biofilms are considered to aggregate primary particles, but experimental proof is still missing. In our experiment, soil aggregate samples were treated with biofilm degrading enzymes and showed a reduced POM occlusion and an increased bacteria DNA release compared with untreated samples. Thus, biofilms are assumed to be an important factor of POM occlusion in soil aggregates.

Short summary
Freezing can affect dissolved organic matter properties and concentrations. Nevertheless, water samples are regularly frozen for sample preservation. To test, if fast-freezing with liquid nitrogen instead of normal freezing at −18 °C can prevent changes in DOM characteristics, we compared fresh and differently frozen terrestrial water samples. We found that fast-freezing with liquid nitrogen can prevent bulk organic matter concentrations but not its spectroscopic properties.

Short summary
The AWAT (Adaptive Window and Adaptive Threshold) filter routine for high-resolution lysimeter data is improved. The threshold scheme with original step interpolation yields unrealistic fluxes for high temporal resolution. Improvement applies linear and spline interpolation schemes so that fluxes in high temporal resolution are automatically calculated. The spline scheme allows continuous differentiability of filtered data so that any output resolution for the fluxes is sound.

Short summary
Soil microbial biofilms are supposed to increase agglomeration of soil particles and therefore reduce erodibility. After inoculation with two strongly differing microbial communities, a sandy agricultural soil did not develop significant differences in aggregate stability. This leads to the assumption that mechanical properties of biofilms do not vary considerably across different biological/chemical compositions, which implies that aggregate stability is a resilient factor of soil fertility.

Humanity depends on the existence of healthy soils, both for the production of food and for ensuring a healthy, biodiverse environment. In the face of global crises like the COVID-19 pandemic, a sustainable soil management strategy is essential to ensure food security based on more diverse, locally oriented, and resilient food production systems through improving access to land, sound land use planning, sustainable soil management, enhanced research, and investment in education and extension.

Soil health is an important term in the international policy arena when considering soil contributions to sustainable development. We propose a measurement method, lacking so far, and explore differences within the term soil quality. The latter describes the inherent properties of soils, while soil health focuses on actual health. The procedure is illustrated for three Italian soil types, also showing the effects of climate change, demonstrating that each soil is significantly different.

Short summary
We evaluated soil fertility in seven watersheds on the East India Plateau, finding that soils are acid and infertile, with low chemical fertiliser use, and organic nutrient recycling is insufficient to maintain soil fertility. This leads to inefficient rainfall use and low yields. Fertiliser rates need to increase greatly, notably in P and K. This will challenge risk-averse subsistence farmers. Field-specific fertiliser regimes are needed despite consistent fertility trends along toposequences.

In this paper, we quantify the global-level relationship between soil organic matter and crop yield. We find that greater concentrations of soil organic matter are associated with greater yields and that increases in yields saturate around 2 % SOC. Using the relationship that we generate, we then provide an estimate of the potential for soil organic matter management to reduce global yield gaps for two of the most important staple crops (maize and wheat) grown worldwide.

Short summary
In a field experiment in Tanzania, we used substrates from local projects as soil amenders for intercropping relevant local crops, aiming to advance the practical application of known principles for smallholder agriculture in SSA, i.e. biochar and biogas application and EcoSan practices. We studied the short-term effects on crop productivity, plant nutrition and soil properties. By mitigating P scarcity and acidification, yields were increased by up to 400 % compared to the control.
