This dataset consists of measures of topsoil mineralisable nitrogen (Mineral-N) from soils sampled from up to 256 1km squares across Great Britain in 2007. The Countryside Survey is a unique study or 'audit' of the natural resources of the UK's countryside. The sample sites are chosen from a stratified random sample, based on a 15 by 15 km grid of GB. Surveys have been carried out in 1978, 1984, 1990, 1998 and 2007 by the Centre for Ecology and Hydrology, with repeated visits to the majority of squares. The countryside is sampled and surveyed using rigorous scientific methods, allowing us to compare new results with those from previous surveys. In this way we can detect the gradual and subtle changes that occur in the UK's countryside over time. In addition to soil data, habitat areas, vegetation species data, linear habitat data, and freshwater habitat data are also gathered by Countryside Survey.

This dataset is part of the following
Soil samples were collected in the summer of 2007 by professional field surveyors. Soils were sampled from up to 591 1km squares sited across Britain, selected by random stratified sample. A sub-sample from up to 256 1km squares were analysed for mineral-N according to standardised protocols at the Centre for Ecology and Hydrology in 2007. Data are managed by the Centre for Ecology and Hydrology.
