Topsoil Ca content, effective cation exchange capacity, and pH were substantially higher under Sennasiamea than under Leucaena leucocephala, Gliricidia sepium, or the no-tree control plots in sites with a Bt horizon rich in exchangeable Ca. This was shown to be largely related to the recovery of Ca from the subsoil under Senna trees. The increase of the Ca content of the topsoil under Senna relative to the no-tree control treatment was related to the total amount of dry matter applied since trial establishment. The lack of increase in Ca accumulation under the other species was related to potential recovery of Ca from the topsoil itself and/or substantial Ca leaching. The accumulation of Ca in the topsoil under Senna had a marked effect on the topsoil pH, the latter increasing significantly compared with the Leucaena, Gliridia, and no-tree control treatments. In conclusion, the current work shows that the functioning of the often hypothesized \u2018safety-net\u2019 of trees in a cropping system depends on (i) the tree species and on (ii) the presence of a subsoil of suitable quality, i.e., clay enriched and with high Ca saturation.", "keywords": ["0106 biological sciences", "senna siamea", "topsoil", "01 natural sciences", "savannas", "agroforestry", "plant litter", "calcio", "subsoil", "top soil", "sabanas", "2.

In this study we estimate SOC saturation in French topsoil (0\u201330 cm) and subsoil (30\u201350 cm), using the Hassink equation and calculate the additional SOC sequestration potential (SOCsp) by the difference between SOC saturation and fine fraction C on an unbiased sampling set of sites covering whole mainland France. We then map with fine resolution the geographical distribution of SOCsp over the French territory using a regression Kriging approach with environmental covariates. Results show that the controlling factors of SOCsp differ from topsoil and subsoil. The main controlling factor of SOCsp in topsoils is land use. Nearly half of forest topsoils are over-saturated with a SOCsp close to 0 (mean and standard error at 0.19 \u00b1 0.12) whereas cropland, vineyard and orchard soils are largely unsaturated with degrees of C saturation deficit at 36.45 \u00b1 0.68% and 57.10 \u00b1 1.64%, respectively. The determinant of C sequestration potential in subsoils is related to parent material. There is a large additional SOCsp in subsoil for all land uses with degrees of C saturation deficit between 48.52 \u00b1 4.83% and 68.68 \u00b1 0.42%. Overall the SOCsp for French soils appears to be very large (1008 Mt C for topsoil and 1360 Mt C for subsoil) when compared to previous total SOC stocks estimates of about 3.5 Gt in French topsoil. Our results also show that overall, 176 Mt C exceed C saturation in French topsoil and might thus be very sensitive to land use change.", "keywords": ["soil organic carbon", "Earth and Environmental Science", "Soils and soil sciences", "13.

Especially under wet soil conditions, when soil is susceptible to compaction, heavy wheel load field traffic can lead to harmful soil compaction. This data set contains soil data from a wheeling experiment with an agricultural vehicle (2-axle combine harvester with bunker; total weight: 17 t). The experiment was conducted in 2016 on an agricultural test field in Adenstedt (Hildesheim district, Lower Saxony, Germany) during the harvest campaign. The soil type is Stagnic Luvisol derived from Loess and was conventionally tilled with a plough up to a depth of 28 cm. The cultivated crop was winter wheat. For the wheeling experiment, a combine harvester with full bunker volume passed defined plots in the field. In the inner field area, the number of wheel passes were 2 and in the headlands the number of wheel passes were 6. The sampling sites were both located in the inner field area and in the headlands. To investigate changes in soil physical parameters, soil structure, and soil functions caused by combine harvester driving, undisturbed soil cores (100 cm\u00b3) were taken before (unwheeled) and after wheeling (wheeled). The unwheeled soil samples were taken in 22, 35, and 50 depth and the wheeled soil samples in 20, 35, and 50 cm depth. In the inner field area, two soil pits were sampled per wheeling variant and in the headlands, one soil pit was sampled per wheeling variant. Additionally, the soil biopores were counted in every one of the three soil depths. A total of 30 undisturbed soil samples were taken per each soil pit, 10 per each soil depth.5 of the 10 undisturbed sampling rings were used to investigate soil water retention and the other 5 for saturated hydraulic conductivity. The determination of pF values was conducted in the soil laboratory using sand and clay boxes as well as pressure pots according to DIN ISO 11274. Saturated hydraulic conductivity was analyzed using a soil water permeameter (open system) according to ISO / FDIS 17312. The soil parameters total pore volume, air capacity, field capacity, usable field capacity, permanent wilting point, dry bulk density, and current water content during soil sampling were derived from the soil laboratory results.\n\nResearch domain: Soil Sciences", "formats": [{"name": "CSV"}], "keywords": ["Soil", "Top soil", "Subsoil", "soil compaction", "Soil pore system", "Soil porosity", "Soil macropores", "Field capacity", "Wilting point", "Hydraulic conductivity", "agriculture", "Vehicles", "Harvesters", "Tillage", "Conservation tillage", "Conventional tillage", "Ploughing", "management", "Management techniques", "On-farm research", "Field experimentation", "Traffic", "Soil sampling", "Bodenfunktion", "Bodenstruktur", "Physikalische Ver\u00e4nderung", "Bodenwasser", "Bodenschutz", "Bodenuntersuchung", "Probenahme", "Boden", "opendata", "Soil physical parameters", "Soil density", "Dry bulk density", "Soil water content", "Soil deformation", "Soil hydraulic properties", "Soil water retention", "Air capaciy", "Plant available water", "Agricultural machineries", "Agricultural management", "Soil management", "Field experiment", "Wheeling experiment", "Field traffic", "Soil conserving traffic"], "contacts": [{"name": "Weise, Maike", "organization": "Th\u00fcnen Institute of Agricultural Technology", "position": "Research associate", "roles": ["author"], "phones": [{"value": null}], "emails": [{"value": "maike.weise@thuenen.de"}], "addresses": [{"deliveryPoint": ["Bundesallee 47"], "city": "Braunschweig", "administrativeArea": null, "postalCode": "38116", "country": "Germany"}], "links": [{"href": null}]}, {"name": "Lorenz, Marco", "organization": "Th\u00fcnen Institute of Agricultural Technology", "position": "Research associate", "roles": ["author"], "phones": [{"value": null}], "emails": [{"value": "marco.lorenz@thuenen.de"}], "addresses": [{"deliveryPoint": ["Bundesallee 47"], "city": "Braunschweig", "administrativeArea": null, "postalCode": "38116", "country": "Germany"}], "links": [{"href": null}]}, {"name": "Ortmeier, Berthold", "organization": "-", "position": null, "roles": ["other"], "phones": [{"value": null}], "emails": [{"value": "-"}], "addresses": [{"deliveryPoint": [null], "city": null, "administrativeArea": null, "postalCode": null, "country": null}], "links": [{"href": null}]}, {"name": "Brunotte, Joachim", "organization": "Th\u00fcnen Institute of Agricultural Technology", "position": "Research associate", "roles": ["projectLeader"], "phones": [{"value": null}], "emails": [{"value": "joachim.brunotte@thuenen.de"}], "addresses": [{"deliveryPoint": ["Bundesallee 47"], "city": "Braunschweig", "administrativeArea": null, "postalCode": "38116", "country": "Germany"}], "links": [{"href": null}]}, {"name": "Lorenz, Marco", "organization": "Th\u00fcnen Institute of Agricultural Technology", "position": "Research associate", "roles": ["projectManager"], "phones": [{"value": null}], "emails": [{"value": "marco.lorenz@thuenen.de"}], "addresses": [{"deliveryPoint": ["Bundesallee 47"], "city": "Braunschweig", "administrativeArea": null, "postalCode": "38116", "country": "Germany"}], "links": [{"href": null}]}, {"name": "Thomas, Celina", "organization": "Th\u00fcnen Institute of Agricultural Technology", "position": "Research associate", "roles": ["dataCurator"], "phones": [{"value": null}], "emails": [{"value": "celina.thomas@thuenen.de"}], "addresses": [{"deliveryPoint": ["Bundesallee 47"], "city": "Braunschweig", "administrativeArea": null, "postalCode": "38116", "country": "Germany"}], "links": [{"href": null}]}, {"name": "BonaRes Data Centre", "organization": "Leibniz Centre for Agricultural Landscape Research (ZALF)", "position": "Research Platform 'Data Analysis & Simulation' -

Especially under wet soil conditions, when soil is susceptible to compaction, heavy wheel load field traffic can lead to harmful soil compaction. This data set contains soil data from a wheeling experiment with agricultural vehicles from the silage maize harvest chain (maize chopper (total weight: 20 t), tractor with mulcher (total weight: 75 t), and tractor with silage trailer (total weight: 32 t)). The experiment was conducted in 2016 on an agricultural test field in Adenstedt (Hildesheim district, Lower Saxony, Germany). The soil type is Stagnic Luvisol derived from Loess and was tilled with a cultivator up to a depth of 25 cm (reduced tillage). For the wheeling experiment, the harvest chain vehicles passed defined plots in the inner field area one after another (8 wheel passes). Maximum soil pressure und plastic soil deformation evoked by vehicle passing was measured simultaneously with a multi-channel device consisting of Bolling probes (Bolling, 1987) and hydrostatic measuring hoses (Nolting et al., 2006). Maximum soil pressure and plastic soil deformation was measured in 20, 35, and 50 cm depth directly below the center of the tires. To investigate changes in soil physical parameters, soil structure, and soil functions caused by harvest chain vehicles driving, undisturbed soil cores (100 cm\u00b3) were taken before (unwheeled) and after wheeling (wheeled). The sampling sites were located in the inner field area. Two soil pits were sampled per wheeling variant. A total of 30 undisturbed soil samples were taken per each soil pit, 10 per each soil depth (20, 35, 50 cm). The soil biopores were counted in every one of the three soil depths. 5 of the 10 undisturbed sampling rings were used to investigate soil water retention and the other 5 for saturated hydraulic conductivity. The determination of pF values was conducted in the soil laboratory using sand and clay boxes as well as pressure pots according to DIN ISO 11274. Saturated hydraulic conductivity was analyzed using a soil water permeameter (open system) according to ISO / FDIS 17312. The soil parameters total pore volume, air capacity, field capacity, usable field capacity, permanent wilting point, dry bulk density, and current water content during soil sampling were derived from the soil laboratory results.\n\nResearch domain: Soil Sciences", "formats": [{"name": "CSV"}], "keywords": ["Soil", "Top soil", "Subsoil", "soil compaction", "Soil pore system", "Soil porosity", "Soil macropores", "Field capacity", "Wilting point", "Hydraulic conductivity", "agriculture", "Vehicles", "Harvesters", "Tillage", "Conservation tillage", "Conventional tillage", "Ploughing", "management", "Management techniques", "On-farm research", "Field experimentation", "Traffic", "Soil sampling", "Bodenfunktion", "Bodenstruktur", "Physikalische Ver\u00e4nderung", "Bodenwasser", "Bodenschutz", "Bodenuntersuchung", "Probenahme", "opendata", "Boden"], "contacts": [{"name": "Weise, Maike", "organization": "Th\u00fcnen Institute of Agricultural Technology", "position": "Research associate", "roles": ["author"], "phones": [{"value": null}], "emails": [{"value": "maike.weise@thuenen.de"}], "addresses": [{"deliveryPoint": ["Bundesallee 47"], "city": "Braunschweig", "administrativeArea": null, "postalCode": "38116", "country": "Germany"}], "links": [{"href": null}]}, {"name": "Lorenz, Marco", "organization": "Th\u00fcnen Institute of Agricultural Technology", "position": "Research associate", "roles": ["author"], "phones": [{"value": null}], "emails": [{"value": "marco.lorenz@thuenen.de"}], "addresses": [{"deliveryPoint": ["Bundesallee 47"], "city": "Braunschweig", "administrativeArea": null, "postalCode": "38116", "country": "Germany"}], "links": [{"href": null}]}, {"name": "Ortmeier, Berthold", "organization": "-", "position": null, "roles": ["other"], "phones": [{"value": null}], "emails": [{"value": "-"}], "addresses": [{"deliveryPoint": [null], "city": null, "administrativeArea": null, "postalCode": null, "country": null}], "links": [{"href": null}]}, {"name": "Brunotte, Joachim", "organization": "Th\u00fcnen Institute of Agricultural Technology", "position": "Research associate", "roles": ["projectLeader"], "phones": [{"value": null}], "emails": [{"value": "joachim.brunotte@thuenen.de"}], "addresses": [{"deliveryPoint": ["Bundesallee 47"], "city": "Braunschweig", "administrativeArea": null, "postalCode": "38116", "country": "Germany"}], "links": [{"href": null}]}, {"name": "Lorenz, Marco", "organization": "Th\u00fcnen Institute of Agricultural Technology", "position": "Research associate", "roles": ["projectManager"], "phones": [{"value": null}], "emails": [{"value": "marco.lorenz@thuenen.de"}], "addresses": [{"deliveryPoint": ["Bundesallee 47"], "city": "Braunschweig", "administrativeArea": null, "postalCode": "38116", "country": "Germany"}], "links": [{"href": null}]}, {"name": "Thomas, Celina", "organization": "Th\u00fcnen Institute of Agricultural Technology", "position": "Research associate", "roles": ["dataCurator"], "phones": [{"value": null}], "emails": [{"value": "celina.thomas@thuenen.de"}], "addresses": [{"deliveryPoint": ["Bundesallee 47"], "city": "Braunschweig", "administrativeArea": null, "postalCode": "38116", "country": "Germany"}], "links": [{"href": null}]}, {"name": "BonaRes Data Centre", "organization": "Leibniz Centre for Agricultural Landscape Research (ZALF)", "position": "Research Platform 'Data Analysis & Simulation' -

Especially under wet soil conditions, when soil is susceptible to compaction, heavy wheel load field traffic can lead to harmful soil compaction. This data set contains soil data from a wheeling experiment with an agricultural vehicle (3-axle sugar beet harvester). The experiment was conducted in 2016 on an agricultural test field in Adenstedt (Hildesheim district, Lower Saxony, Germany). The soil type is Stagnic Luvisol derived from Loess and was tilled with a cultivator up to a depth of 25 cm (reduced tillage). For the wheeling experiment, the harvester passed defined plots in the field with a full bunker (total weight: 62 t) and a half full bunker (total weight: 49 t). Maximum soil pressure and plastic soil deformation evoked by harvester passing was measured simultaneously with a multi-channel device consisting of Bolling probes (Bolling, 1987) and hydrostatic measuring hoses (Nolting et al., 2006). Maximum soil pressure and plastic soil deformation was measured in 20, 35, and 50 cm depth directly below the center of the tires. To investigate changes in soil physical parameters, soil structure, and soil functions caused by harvester driving, undisturbed soil cores (100 cm\u00b3) were taken before (unwheeled) and after wheeling (wheeled). Wheeling variants in the inner field area were sugar beet harvester with half full bunker and full bunker volume driving with all wheels in the same track (3 wheel passes). The wheeling variant of the headland area was sugar beet harvester with full bunker volume and multiple wheel passes in front of the sugar beet clamp. The sampling sites were located both in the inner field area and in the headlands. Two soil pits were sampled per wheeling variant in the inner field area and one soil pit in the headlands. A total of 30 undisturbed soil samples were taken per each soil pit, 10 per each soil depth (20, 35, 50 cm). The soil biopores were counted in every one of the three soil depths. 5 of the 10 undisturbed sampling rings were used to investigate soil water retention and the other 5 for saturated hydraulic conductivity. The determination of pF values was conducted in the soil laboratory using sand and clay boxes as well as pressure pots according to DIN ISO 11274. Saturated hydraulic conductivity was analyzed using a soil water permeameter (open system) according to ISO / FDIS 17312. The soil parameters, total pore volume, air capacity, field capacity, usable field capacity, permanent wilting point, dry bulk density, and current water content during soil sampling were derived from the soil laboratory results.\n\nResearch domain: Soil Sciences", "formats": [{"name": "CSV"}], "keywords": ["Soil", "Top soil", "Subsoil", "soil compaction", "Soil pore system", "Soil porosity", "Soil macropores", "Field capacity", "Wilting point", "Hydraulic conductivity", "agriculture", "Vehicles", "Harvesters", "Tillage", "Conservation tillage", "Conventional tillage", "Ploughing", "management", "Management techniques", "On-farm research", "Field experimentation", "Traffic", "Soil sampling", "Bodenfunktion", "Bodenstruktur", "Physikalische Ver\u00e4nderung", "Bodenwasser", "Bodenschutz", "Bodenuntersuchung", "Probenahme", "Boden", "opendata", "Soil physical parameters", "Soil density", "Dry bulk density", "Soil water content", "Soil deformation", "Soil hydraulic properties", "Soil water retention", "Air capacity", "Plant available water", "Agricultural machineries", "Agricultural management", "Soil management", "Field experiment", "Wheeling experiment", "Field traffic", "Soil conserving traffic"], "contacts": [{"name": "Weise, Maike", "organization": "Th\u00fcnen Institute of Agricultural Technology", "position": "Research associate", "roles": ["author"], "phones": [{"value": null}], "emails": [{"value": "maike.weise@thuenen.de"}], "addresses": [{"deliveryPoint": ["Bundesallee 47"], "city": "Braunschweig", "administrativeArea": null, "postalCode": "38116", "country": "Germany"}], "links": [{"href": null}]}, {"name": "Lorenz, Marco", "organization": "Th\u00fcnen Institute of Agricultural Technology", "position": "Research associate", "roles": ["author"], "phones": [{"value": null}], "emails": [{"value": "marco.lorenz@thuenen.de"}], "addresses": [{"deliveryPoint": ["Bundesallee 47"], "city": "Braunschweig", "administrativeArea": null, "postalCode": "38116", "country": "Germany"}], "links": [{"href": null}]}, {"name": "Ortmeier, Berthold", "organization": "-", "position": null, "roles": ["other"], "phones": [{"value": null}], "emails": [{"value": "-"}], "addresses": [{"deliveryPoint": [null], "city": null, "administrativeArea": null, "postalCode": null, "country": null}], "links": [{"href": null}]}, {"name": "Brunotte, Joachim", "organization": "Th\u00fcnen Institute of Agricultural Technology", "position": "Research associate", "roles": ["projectLeader"], "phones": [{"value": null}], "emails": [{"value": "joachim.brunotte@thuenen.de"}], "addresses": [{"deliveryPoint": ["Bundesallee 47"], "city": "Braunschweig", "administrativeArea": null, "postalCode": "38116", "country": "Germany"}], "links": [{"href": null}]}, {"name": "Lorenz, Marco", "organization": "Th\u00fcnen Institute of Agricultural Technology", "position": "Research associate", "roles": ["projectManager"], "phones": [{"value": null}], "emails": [{"value": "marco.lorenz@thuenen.de"}], "addresses": [{"deliveryPoint": ["Bundesallee 47"], "city": "Braunschweig", "administrativeArea": null, "postalCode": "38116", "country": "Germany"}], "links": [{"href": null}]}, {"name": "Thomas, Celina", "organization": "Th\u00fcnen Institute of Agricultural Technology", "position": "Research associate", "roles": ["dataCurator"], "phones": [{"value": null}], "emails": [{"value": "celina.thomas@thuenen.de"}], "addresses": [{"deliveryPoint": ["Bundesallee 47"], "city": "Braunschweig", "administrativeArea": null, "postalCode": "38116", "country": "Germany"}], "links": [{"href": null}]}, {"name": "BonaRes Data Centre", "organization": "Leibniz Centre for Agricultural Landscape Research (ZALF)", "position": "Research Platform 'Data Analysis & Simulation' -
