Abstract:
This experiment began in 1958 at a site that has been in arable crops for more than 100 years. The climate of the site is cool temperate, with mean annual temperature of 9.1 deg. C, and Mean annual rainfall of 598mm. The experiment consists of Cereals only with either inorganic fertilizers only (2 types) or inorganic fertilizers (2 types) plus straw incorporation, in a block design, replicated 4 times. The soil at the site is described as an Orthic luvisol (FAO) [derived from loess]. The measurements made, methodology, and frequency are listed below: a) Vegetation measurements made and frequency Yield: Yearly Total above-ground dry matter: Yearly Total dry matter offtake: Yearly Nitrogen content of offtake: Yearly b) Soil sampling Details of soil sampling method: Sampled by auger (30cm x 3cm), 10 cores per plot (total plot area 7.0 x 3.0m; sampled area about 5 x 2.5m). Sampling is randomized. The ploughing depth (and sampling depth) was increased from 15 to 20cm in 1969 and from 20 to 30cm in 1986 (due to available technical equipment for soil tillage). c) Soil measurements made and frequency Total carbon: Every 2 to 5 years Method of measuring total carbon: Wet digestion with 2 N K2Cr2O7 according to Hoffmann 1991 (VDLUFA - Methodenbuch). Biomass carbon: Once in 1989 Method of measuring biomass carbon: SIR method according to Anderson and Domsch (1978) Soil Biol. Biochem. 10; 215-221. Total nitrogen: Every 2 to 5 years Method of measuring total nitrogen: Wet digestion (Kjeldahl) and Dry combustion (Dumas) using a Carlo ERBA Analyzer Total mineral nitrogen: Irregularly Method of measuring total mineral nitrogen: Soil extraction with K2SO4 (10g K2SO4/l), filtration, NO3-N and NH4-N were measured using a continuous flow analyzer (Technicon Autoanalyzer) Biomass nitrogen: Once in 1995 Method of measuring biomass nitrogen: FE method according to Brookes et al. (1985), Soil. Biol. Biochem. 17: 837-842., total N in extracts measured using continuous flow analyzer (Technicon Analyzer) Nitrogen measurements in other organic matter fractions: Once in 1995 Method of measuring nitrogen in other organic matter fractions: Dissolved organic nitrogen: Extraction with 0.01 M CaCl2 solution according to Houba et al. (1986) Plant & Soil 96: 433-437. Other nutrients: Phosphate, Potassium d) Details of the meteorological station Nearest meteorological station to the site: Klein-Altendorf which is .4 km from the site at coordinates 7deg.00min. East, 30deg.36min. North Meteorological data is available from both a manual and an automatic station. e) Meteorological data available and frequency Rainfall: Daily Air temperature: Daily Soil temperature: Daily at 20cm depth Wind speed: Daily (since 1993) Relative humidity: Daily (since 1993) This information was compiled for the GCTE-SOMNET Database, Pete Smith, Pete Falloon, David Powlson, and Jo Smith.
