Abstract:
Collection of data for this data set began in 1967. The Data are collected at a cool temperate site which had mixed arable cropping for many years. The crops were: springbarley 1967-1983; winter barley 1983-1992; 1992 to present grass. This project is currently suspended until further notice. The soil at the site is described as follows: Half of site on a eutric cambisol (Macmerry series) [FAO] and half is on a gleysol (Winton/Macmerry complex) [FAO]. On the Macmerry series a loam topsoil plough layer (0-25cm) overlies a sandy clay loam subsoil and on the Winton series/Winton-Macmerry complex, the topsoil varies from loam to sandy clay loam and the subsoil is a poorly drained clay loam. The land use and treatments are as follows; Spring barley (1967-1983), Winter barley (1983-1992), Silage grass (1992). Treatments: Deep ploughing (33cm - spring barley only), Normal ploughing (25cm - all crops), Direct drilling with no tillage (all crops), chisel ploughing (30cm, spring barley only), Shallow tillage (7cm) and seed broadcasting (winter barley only), N fertilizer application (0, 60, 120 and 180 kg N / ha - spring barley only), N fertilizer application in spring (150 and 225 kg N / ha - winter barley only). The measurements taken (data available), methodology, and frequency are as follows: a) Vegetation measurements made and frequency Yield: Yearly Nitrogen content of offtake: Yearly b) Soil sampling Time zero soil measurements taken. Disturbed soil samples taken from 0-15, 15-30 and 30-45cm depth. Bulk density, plastic limits, particle density, porosity, particle size analysis and loss-on-oxidation were measured (no total carbon by any other method). See Soane, Campbell & Herkes (1970) [see reference list]. Stored samples were kept. Details of soil sampling method: Variable: Usually augering to 15-40cm for particle size, organic matter etc. Occasionally a trowel, spade or C section auger have been used. For diffusion, permeability and porosity measurements, undisturbed cores were taken. Many different methods used. Soil is separated into layers Details of measuring depths and soil layers: Many and varied: 0-36cm in 6cm intervals, also 0-10, 15, 20, or 25 cm in 5 cm intervals. Frequency varies also from once every four years for plant nutrients and organic matter to annually for cone resistance, bulk density etc. c) Soil measurements made and frequency Total carbon: Every 4 years from 1978 Method of measuring total carbon: Total carbon by Carlo Erba CHN Analyzer in 1990 only. Organic carbon every 4 years by dichromate oxidation method. Loss-on-oxidation by oxidation with H2O2 as in the pre-treatment for the analysis of particle-size-distribution. Loss-on-ignition on at least two occasions. Biomass carbon: 1979 only Method of measuring biomass carbon: From CO2-C evolved from fumigated soil - Jenkinson & Powlson (1976) Soil Biol. Biochem. 8: 209-213. Carbon measurements in other organic matter fractions: 1990 only Method of measuring carbon in other organic matter fractions: Carbohydrates released in different solutions (cold water, hot water, HCl and NaOH) See Ball, Cheshire, Robertson & Hunter (1995) Soil Tillage Research [see reference list] Total nitrogen: 1990 only Method of measuring total nitrogen: Total N by Carlo Erba CHN Analyzer Total mineral nitrogen: 1984 only Method of measuring total mineral nitrogen: Extraction by KCl and subsequent determination by continuous flow analysis (see Smith, Howard & Crichton (1988) In: Nitrogen efficiency in Agricultural Soils, Elsevier: 73-84) Soil bulk density or weight: Every 4-5 years Method of measuring soil bulk density or weight: Gamma ray attenuation and using undisturbed soil cores (see publications by Ball and others and by Sullivan in reference list) Other nutrients: Available phosphorus, potassium, calcium and magnesium. Other measurements: Soil N2O and N2O emissions were measured in 1984 and 1985; methane uptake in 1995. See Arah & Smith (1991) J.Soil. Sci. 42: 351-368 and Ball (1995) in: Proc. 2nd EU Workshop on Experience with the applicability of no tillage... - see reference list). d) Details of the meteorological station Nearest meteorological station to the site: Bush House which is 3 km from the site. The meteorological station is manual. e) Meteorological data available and frequency Rainfall: Daily Air temperature: Daily Soil temperature: Daily Wind speed: Daily Net Radiation: Daily Sun hours: Daily Relative humidity: Daily f) Isotope measurements available and frequency Nitrogen 15 measurements in vegetation: 1985 and 1986 only Details of isotope measurements: N15 content in plant and grain samples by mass spectrometry (See Smith, Howard & Crichton (1988) In: Nitrogen efficiency in Agricultural soils. Elsevier: 73-84). g) Archived samples available Archived soil samples: Every 8-9 years dating from 1967 This information was compiled for the GCTE-SOMNET Database, Pete Smith, Pete Falloon, David Powlson, and Jo Smith.

a) Details of the plots Width of smallest plot is 6 m; Length of smallest plot is 22.5 m; Width of largest plot is 12 m; Length of largest plot is 45 m . Shape: Slight dip between pairs of replicates; concave. Direction of cultivation is parallel to long-axis of the plot. Width of Bare Strip around plot: 12-25m. Width of Discard Strip around plot: 1m Details of homogeneity of the plots: Soil type, variability details available as are drainage and contour plans. A discussion of the soil variablity can be found in Pidgeon (1980) Journal of Soil Science 31: 581-594 [see reference list]) b) Details of replication, randomization and controls There are at least 8 replicates in the experiment. The control treatment in this experiment is considered to be the normal ploughing treatment. An old deciduous wood is adjacent to the south end of the experiment. In areas where drainage was poor and was considered to be influencing crop yield, covariance analysis was used. See Ball et al. (1994) Soil Tillage Research 31: 97-118 [see reference list])
