This paper describes an agricultural model (Roth-CNP) that estimates carbon (C), nitrogen (N) and phosphorus (P) pools, pool changes, their balance and the nutrient fluxes exported from arable and grassland systems in the UK during 1800–2010. The Roth-CNP model was developed as part of an Integrated Model (IM) to simulate C, N and P cycling for the whole of UK, by loosely coupling terrestrial, hydrological and hydro-chemical models. The model was calibrated and tested using long term experiment (LTE) data from Broadbalk (1843) and Park Grass (1856) at Rothamsted. We estimated C, N and P balance and their fluxes exported from arable and grassland systems on a 5 km × 5 km grid across the whole of UK by using the area of arable of crops and livestock numbers in each grid and their management. The model estimated crop and grass yields, soil organic carbon (SOC) stocks and nutrient fluxes in the form of NH4-N, NO3-N and PO4-P. The simulated crop yields were compared to that reported by national agricultural statistics for the historical to the current period. Overall, arable land in the UK have lost SOC by −0.18, −0.25 and −0.08 Mg C ha−1 y−1 whereas land under improved grassland SOC stock has increased by 0.20, 0.47 and 0.24 Mg C ha−1 y−1 during 1800–1950, 1950–1970 and 1970–2010 simulated in this study. Simulated N loss (by leaching, runoff, soil erosion and denitrification) increased both under arable (−15, −18 and −53 kg N ha−1 y−1) and grass (−18, −22 and −36 kg N ha−1 y−1) during different time periods. Simulated P surplus increased from 2.6, 10.8 and 18.1 kg P ha−1 y−1 under arable and 2.8, 11.3 and 3.6 kg P ha−1 y−1 under grass lands 1800–1950, 1950–1970 and 1970–2010.

Highlights•Oat cropping was linked to a seasonal L. terrestris population collapse.•Very low L. terrestris populations (0–4.6 middens per m2) found.•Wheat and barley straw (p ≤ 0.05) enhanced residual L. terrestris populations.•Is L. terrestris functionally extinct at these densities? AbstractThis work assessed populations of the anecic, deep burrowing earthworm Lumbricus terrestris on two recently established (3 years) and two long running (20–170 years) organic matter amended, conventionally managed arable field trials in SE England. Validated midden counts and DNA analyses were used to estimate L. terrestris populations and check species identity (>98% match, n = 10). Population estimates ranged between 0 and 1.3 L. terrestris middens per m2 on conventionally (inorganic fertiliser only) managed plots. Surface wheat straw applications (p ≤ 0.05) or wastes mixed with barley straw (p ≤ 0.05) enhanced L. terrestris midden abundances. However, these were very low at <4.6 L. terrestris middens per m2 and a population collapse was recorded under oat cropping. We found a residual population ranging between 0.1–3.6 L. terrestris middens per m2 on the long running field trials. Further investigations are needed to identify if L. terrestris is functionally extinct at these densities.

Highlights•Soils rewetted after drying exhibit an extremely rapid flux of CO2, peak efflux occurs in less than 6 min.•Such CO2 fluxes were prevented by autoclaving, suggesting an intrinsically biochemical or organismal origin to the source.•Strong evidence for an extracellular oxidative pathway contributing to such CO2 fluxes was found. AbstractWhen dry soils are rewetted a pulse of CO2 is invariably released, and whilst this phenomenon has been studied for decades, the precise origins of this CO2 remain obscure. We postulate that it could be of chemical (i.e. via abiotic pathways), biochemical (via free enzymes) or biological (via intact cells) origin. To elucidate the relative contributions of the pathways, dry soils were either sterilised (double autoclaving) or treated with solutions of inhibitors (15% trichloroacetic acid or 1% silver nitrate) targeting the different modes. The rapidity of CO2 release from the soils after the drying:rewetting (DRW) cycle was remarkable, with maximal rates of evolution within 6 min, and 41% of the total efflux over 96 h released within the first 24 h. The complete cessation of CO2 eflux following sterilisation showed there was no abiotic (dissolution of carbonates) contribution to the CO2 release on rewetting, and clear evidence for an organismal or biochemical basis to the flush. Rehydration in the presence of inhibitors indicated that there were approximately equal contributions from biochemical (outside membranes) and organismal (inside membranes) sources within the first 24 h after rewetting. This suggests that some of the flux was derived from microbial respiration, whilst the remainder was a consequence of enzyme activity, possibly through remnant respiratory pathways in the debris of dead cells.
