Tropical forests play an important role in the global carbon (C) cycle, yet the effects of N deposition on C cycling in these ecosystems are poorly understood. We used a field N-fertilization experiment in lower and upper elevation tropical rain forests in Puerto Rico to explore the responses of above- and belowground C pools to N addition. As expected, tree stem growth and litterfall productivity did not respond to N fertilization in either of these N-rich forests, indicating a lack of N limitation to net primary productivity (NPP). In contrast, soil C concentrations increased significantly with N fertilization in both forests, leading to larger C stocks in fertilized plots. However, different soil C pools responded to N fertilization differently. Labile (low density) soil C fractions and live fine roots declined with fertilization, while mineral-associated soil C increased in both forests. Decreased soil CO2 fluxes in fertilized plots were correlated with smaller labile soil C pools in the lower elevation forest (R2\u00a0=\u00a00.65, p\u00a0<\u00a00.05), and with lower live fine root biomass in the upper elevation forest (R2\u00a0=\u00a00.90, p\u00a0<\u00a00.05). Our results indicate that soil C storage is sensitive to N deposition in tropical forests, even where plant productivity is not N-limited. The mineral-associated soil C pool has the potential to respond relatively quickly to N additions, and can drive increases in bulk soil C stocks in tropical forests.", "keywords": ["58 Geosciences Aboveground Biomass", "15.

To assess the P mobilization potential, three soil profiles with redoximorphic features were selected along a slight hill slope and soil samples were taken from three different depths.

Thereby, soil bulk density and pore volume give basic soil information about e.g. soil compaction and thus aeration. Soil pH determines e.g. mineral equilibria as well as biological processes. Total element concentrations give information about e.g. available nutrients including total P. P pools give a hint on e.g. P binding. Oxalate extractions inform about elements derived from poorly crystalline pedogenic oxides, dithionite extractions about elements derived from well crystallized oxides. PSC and DPS, calculated from oxalate extractions, give information about P sorption capacity of the soil and the degree of P saturation.

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.

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' -
