The dataset comprises of physical property and biogeochemical measurements of saltmarsh soil collected using the hammer coring technique from the Kyle of Tongue saltmarsh in the North of Scotland. The site was chosen to represent northern, loch head marshes and to test different coring techniques in organic rich soils. The data provides a quantitative measure of the dry bulk density, water content, porosity and organic carbon content present within the soils of the Kyle of Tongue saltmarsh. A total of four cores were collected, 39 samples were collected at 10 cm intervals down the length of each core. The samples were processed for bulk density, water content, porosity and organic carbon content which was quantified through elemental analysis. The data were collected to help create a detailed picture of saltmarsh carbon storage in the soils of UK saltmarsh and test different coring approaches. The cores were collected by the data authors in November 2018. The work was carried out under the NERC programme - Carbon Storage in Intertidal Environment (C-SIDE), NERC grant reference NE/R010846/1 Full details about this dataset can be found at https://doi.org/10.5285/b57ef444-54d4-47f9-8cbf-3cfef1182b55

The dataset comprises of biogeochemical measurements of saltmarsh soil collected from 46 salt marshes across Scotland. Sites were chosen to represent contrasting habitats across Scotland, in particular sediment types, vegetation and sea level history. The data provide a quantitative measure of the dry bulk density, soil texture, organic matter content (LOI) and organic carbon present within surface soils (up to a depth of 10 cm). A total of 471 samples were collected, 157 of the samples were collected using modified syringe samplers as part of the citizen scientist programme CarbonQuest (Part of C-SIDE) these were supplemented by a further 109 samples from the C-SIDE team. The remaining 205 samples were collected using a soil corer (Gouge) as part of the C-SIDE sampling programme. The samples were processed for bulk density, soil texture, organic matter content using the Loss on Ignition (LOI) method and the organic carbon was quantified through elemental analysis. The data were collected to help create a detailed picture of saltmarsh carbon storage across Scotland. The work was carried out under the NERC programme - Carbon Storage in Intertidal Environment (C-SIDE), NERC grant reference NE/R010846/1 Full details about this dataset can be found at https://doi.org/10.5285/81a1301f-e5e2-44f9-afe0-0ea5bb08010f

Data comprise results of a soil survey in England, Scotland and Wales carried out during 2013 and 2014 as part of the NERC Macronutrient Cycles project: LTLS : Analysing and simulating long-term and large-scale interactions of carbon nitrogen and phosphorus in UK land, freshwater and atmosphere. The data include bulk density measurements, charcoal and coal determinations, site locations and sampling dates, site vegetation data, soil chemistry and isotope data, soil classifications, information on soil cores collected and soil texture data.

The dataset details the quantification of three different pools of organic matter (labile, recalcitrant, and refractory) within 1211 down core soil samples collect from across UK saltmarsh sites between 2018 - 2021. Additionally, the dataset presents a measure of organic matter reactivity using the carbon reactivity index (CRI). The work was carried out under the NERC programme - Carbon Storage in Intertidal Environment (C-SIDE), NERC grant reference NE/R010846/1 Full details about this dataset can be found at https://doi.org/10.5285/9a62bb8a-dd88-42d2-9af2-25ec338110e6

Data are presented for soil state and environmental parameters of soil samples collected from paired intensive and extensive grassland systems, including low and high pH parent soils, from 32 sites across the United Kingdom. The samples were collected during winter and spring 2015-2016 by project staff experienced in soil core collection. Samples were subdivided for subsequent analysis of total Nitrogen, total Carbon, total organic Carbon, total Phosphorus, soil pH, soil moisture, loss on ignition, sand, silt, clay texture, Fourier-transform infrared spectroscopy (FT-IR) spectra and bulk density. The data were collected to help understand soil functional change in a variety of management and climatic scenarios as part of NERC U-GRASS (Understanding and enhancing soil ecosystem services and resilience in UK grass and croplands) award (NERC Reference NE/M017125/1) part of the NERC Soil Security Programme.
