Saggau P., Kuhwald M., Hamer W., Duttmann R. (2021.0). Are compacted tramlines underestimated features in soil erosion modeling? A catchment‐scale analysis using a process‐based soil erosion model. Land Degradation & Development, 33(3), 452-469. doi:10.1002/ldr.4161

Process-based model ling has long been used as a well-suited tool to simulate soil erosion. Despite a large number of scientific articles that emphasize the role of compacted tramlines for soil erosion and surficial nutrient transport, no study exists that integrates these artificial structures into…

Cao X., Reichel R., Wissel H., Kummer S., Brüggemann N. (2022.0). High Carbon Amendments Increase Nitrogen Retention in Soil After Slurry Application—an Incubation Study with Silty Loam Soil. Journal of Soil Science and Plant Nutrition, 22(2), 1277-1289. doi:10.1007/s42729-021-00730-7

AbstractExcess nitrogen (N) after animal slurry application is a persistent problem of intensive agriculture, with consequences such as environmental pollution by ammonia (NH3) and nitrous oxide (N2O) emissions and nitrate (NO3−) leaching. High-carbon organic soil amendments (HCAs) with a large C:N …

Bublitz T., Kemper R., Müller P., Kautz T., Döring T., Athmann M. (2021.0). Relating Profile Wall Root-Length Density Estimates to Monolith Root-Length Density Measurements of Cover Crops. Agronomy, 12(1), 48. doi:10.3390/agronomy12010048

Different methods have been proposed for in situ root-length density (RLD) measurement. One widely employed is the time-consuming sampling of soil cores or monoliths (MO). The profile wall (PW) method is a less precise, but faster and less laborious alternative. However, depth-differentiated functio…

Several ecological data types, especially microbiome count data, are commonly sample-wise normalized before analysis to correct for sampling bias and other technical artifacts. Recently, we developed an algorithm for the normalization of ecological count data called ‘scaling with ranked subsampling …

Busnena B., Beuerle T., Mahnkopp-Dirks F., Winkelmann T., Beerhues L., Liu B. (2021.0). Formation and exudation of biphenyl and dibenzofuran phytoalexins by roots of the apple rootstock M26 grown in apple replant disease soil. Phytochemistry, 192(), 112972. doi:10.1016/j.phytochem.2021.112972

Apple replant disease (ARD) is a severe soil-borne disease frequently observed in apple tree nurseries and orchards worldwide. One of the responses of apple trees to ARD is the formation of biphenyl and dibenzofuran phytoalexins in their roots. However, there is no information on whether or not thes…

Vitow N., Zicker T., Chiba A., Zacher A., Eichler-Löbermann B., Schulz S., Schloter M., Baum C., Leinweber P. (2021.0). Impact of the Legume Catch Crop Serradella on Subsequent Growth and P Mobilization under Barley in Different Fertilization Treatments. Agronomy, 11(12), 2437. doi:10.3390/agronomy11122437

Legume catch crops can enhance soil fertility and promote the N and P supply of the subsequent main crop, especially with low mineral fertilizer use. However, the specific impact of catch crops on arbuscular mycorrhiza formation of the following main crop is unknown. Therefore, the impact of serrade…

Steinfurth K., Hirte J., Morel C., Buczko U. (2021.0). Conversion equations between Olsen-P and other methods used to assess plant available soil phosphorus in Europe – A review. Geoderma, 401(), 115339. doi:10.1016/j.geoderma.2021.115339

Plant available soil phosphorus contents are assessed by various different methods worldwide. The resulting country-specific methodology prohibits comparison or joint analysis of international data on yield response to soil P level. A change of the standard method would decrease comparability to old…

Windisch S., Walter A., Moradtalab N., Walker F., Höglinger B., El-Hasan A., Ludewig U., Neumann G., Grosch R. (2021.0). Role of Benzoic Acid and Lettucenin A in the Defense Response of Lettuce against Soil-Borne Pathogens. Plants, 10(11), 2336. doi:10.3390/plants10112336

Soil-borne pathogens can severely limit plant productivity. Induced defense responses are plant strategies to counteract pathogen-related damage and yield loss. In this study, we hypothesized that benzoic acid and lettucenin A are involved as defense compounds against Rhizoctonia solani and Olpidium…

Winklhofer P., Andert S., Hüttel S., Gerowitt B. (2021.0). Measuring On-Farm Phosphorus Fertiliser Use—Lessons Learned from Surveying Data of Five Regions in Northern Germany. Agronomy, 11(11), 2123. doi:10.3390/agronomy11112123

Phosphorus (P) is essential for agriculture; however, local P surpluses can have adverse environmental effects, such as eutrophication. Optimal P fertiliser use, therefore, means balancing these effects. Although P fluxes from soil to plants are key research areas, little is known about on-farm use …

Background Reductions of ammonia volatilization resulting from slurry applications to intensively managed grassland may be achieved via slurry acidification. However, it remains uncertain if this may result in pollution swapping, that is, due to reduced ammonia volatilization and increased soil N av…
