Abstract:
This experimnet began in 1888 at a cool temperate site. The site was used as pasture up until 1886, corn was grown 1887 and 1888. the soil is described as Mexico series (fine montmorillonitic, mesic Udollic Ochraquals). Plots 1-7 (east end of the field) Lindley series (fine-loamy, mixed mesic Typic Hapudalfs) There are 5 land-uses/rotations as follows: 1) Continuous maize, 2) Continuous wheat, 3) Three year maize-wheat-clover, 4) Three year maize-soybean-wheat & 5) Four year maize-oat-wheat-clover. Treatments are as follows: Rotations 1,2, 3 & 5 each receive none, full fertility and manure. In addition rotation 3 & 5 also receives full fertility but N-limited. Rotation 4 receives full fertility, full with no K and full with no P. The measurements made (data available), frequency, and methodology are listed below: a) Vegetation measurements made and frequency Yield: Annual Total above-ground dry matter: Annual for wheat and corn Carbon content of offtake: Occasionally b) Soil sampling Ap soil tests after 5 years. Profile since 1914 near complete characterisation at 25 years. Details of soil sampling method: 1989, 1965 - profile cores - hydraulic corer; systematic, 12 cores 1963, 4 cores 1989 (offset 20 cm from 1963). 1939 - Ap, pit, below-auger, systematic. 1914 - Auger. Soil tests - surface 20cm, tube, random. Soil is separated into layers. Details of measuring depths and soil layers: 1989 - by 10cm increments to 120cm, by diagnostic horizons to 120cm. 1963 - same except depth limited to 120cm diagnostics. 1928 - 0-20cm, 20-45cm and 45-60cm. 1914 - 120cm by 10 and 15cm increments. c) Soil measurements made and frequency Total carbon: Periodic Method of measuring total carbon: Mainly dry combustion (combustion train, since 1985 - LECO carbon analyzer). Biomass carbon: Sporadic Method of measuring biomass carbon: Modified chloroform fumigation and direct extraction method (Jordan & Beare, 1991, Agric. Ecosyst. & Environment 34: 35-41). Carbon measurements in other organic matter fractions: Occaisional Method of measuring carbon in other organic matter fractions: In soil physical fractions by dry combustion (Leco analyzer) Carbon dioxide evolution: 1981-1994 Method of measuring carbon dioxide evolution: CO2 evolution: Static chamber method (Anderson, 1982, Methods of soil analysis, 2nd Ed., ASA-SSSA). CO2 concentration in soil air also measured: disposable chromatographic tubes (Buyanovsky & Wagner, 1983, Soil. Sci. Soc. Am. J. 47: 1139-1145). Total nitrogen: Every 25 years Method of measuring total nitrogen: Kjeldahl (common procedure at the time of sampling). In recent years the Soil Science society of America Methods Manual has been used as a basis of methods. Biomass nitrogen: Measured; frequency unspecified. Method of measuring biomass nitrogen: Extractable nitrate and ammonium in potassium sulfate extracts. Soil bulk density or weight: Every 25 years. Method of measuring soil bulk density or weight: Core volume, dry weight. Other nutrients: Extractable P in 0.025M HCl, 0.03 NH4F. Extractable K, Ca, Mg in 1M NH4 acetate @ pH 7.0. Other measurements: Soil temperature (last decades), soil water content (last decade; non-systematic), soil air CO2 concentration since 1981. Distribution of root biomass. d) Details of the meteorological station Nearest meteorological station to the site: Columbia airport (to 1989; 24 km distant), 1990 to present: on site. which is 0 km from the site at coordinates 93deg.20min. West, 38deg.57min. North. Meteorological data is available from both a manual and an automatic station. e) Meteorological data available and frequency Rainfall: Daily Air temperature: Continuous Soil temperature: Daily at 5cm depth Wind speed: Continuous Net Radiation: Continuous Sun hours: Continuous Relative humidity: Continuous Potential evapotranspiration: Estimated measured/calculated by Estiamted by method of Thornthwaite & Mather, 1955 (Climatology 8: 1-104). f) Isotope measurements available and frequency Total soil carbon 13 measurements: 7 times in between 1915 and 1986. Soil carbon 13 measurements in other organic matter fractions: In silt and clay fractions; frequency not specified. Carbon dioxide carbon 14 measurements: After field labelling; frequency not specified. Details of isotope measurements: Details of isotope measurements in Balesdent et al.

a) Details of the plots Width of smallest plot is 9.5 m Length of smallest plot is 30.6 m Slope: 1.9% to 5% . Shape: Concave Details of direction of cultivation: Parallel to long-axis of plots Width of Bare Strip around plot: 1.5m Width of Discard Strip around plot: 2m Details of homogeneity of the plots: Each plot tends to be unique due to 100 plus years of differential management. Plots on the field summit are eroded - Ap contains mixed B2t material on 2 plots. Soil tends to have deeper A horizons down the slope. Seven plots on 5% slope have significant differences from those upslope. b) Details of replication, randomization and controls Plots act as controls for others. There are some unmanured plots under continuous rotation which can be regarded as control plots. Time is used as a "pseudo replicate".
