Triple Cereal Cropping and Soil Organic Matter Long-term Experiment, China
Entry ID:
ZAAS.Cereal
|
Summary
This experiment began in 1974 at a Warm Temperate SubTropical site in China. The soil was developed from marine deposits but had desalted after long-term cropping and classified as Entisols (Hydric Haplaquents); it is a heavy clay loam and is well drained with medium productivity. The site has been in a typical cereal crop - orange orchard ecosystem for ... centuries. In these areas the lowlands are planted with various cereal crops whilst orange trees are grown over the stripped mounds among the paddy fields. The experiment consists of a single rotation of barley-rice-rice growing all three crops each year and in every year. There are 5 different treatments as follows: 1) High manure - standard inorganic N fertilizer plus high level of pig manure. 2) Low manure - standard inorganic N fertilizer plus low level of pig manure. The following three treatments receive the same total N but the proportion contributed by N fertilizer and pig manure varies as follows: 3) 40% of total N from inorganic N. 4) 60% of total N from inorganic N. 5) 80% of total N from inorganic N. Further details can be found in the references listed in the reference list. The measurments made (data available), frequency, and methodology are listed below: a) Vegetation measurements made and frequency Yield: Each crop every year Nitrogen content of offtake: Every 5 years N, P, K, Na, Ca, Mg, Fe, Mn, S, Cu, Zn, Mo & B every 5-10 years. Also many agronomic measurements on the crop (e.g. plant tillering, height, panicle length and granules, 1000 granules weight etc.) b) Soil sampling Time zero soil measurements taken. Collected and stored. Sampling depth was 17 cm. Analyzed for routine chemical and physical properties. Details of soil sampling method: Spade used to sample surface soil in plow layer over the whole area (multiple plots) of each treatment block. c) Soil measurements made and frequency Total carbon: Yearly Method of measuring total carbon: Tyrine method as modified by Black & Walkley. Carbon measurements in other organic matter fractions: 10 yearly Method of measuring carbon in other organic matter fractions: Kononoba method as modified by Y. Xiong. Total nitrogen: 5 yearly Method of measuring total nitrogen: Kjeldahl method Total mineral nitrogen: Yearly Ammonium nitrogen: Yearly Method of measuring ammonium nitrogen: Conway method (N NaOH diffused soil NH4-N in Conway dish at 40 deg. C for 24 hours). Soil bulk density or weight: Every 10 years Method of measuring soil bulk density or weight: Routine method (standard stainless steel ring) Other nutrients: N, P, K, Na, Ca, Mg, Fe, Mn, S, Cu, Zn, Mo, B. Other measurements: Analysis of soil enzymes such as invertase, protease, urease, dehydrogenase, polyphenol oxidase, phosphatase etc. d) Details of the meteorological station Nearest meteorological station to the site: Hong Jia Meteorological Station which is 7.5 km from the site at coordinates 121deg.25min. East, 28deg.37min. North. The meteorological station is manual. e) Meteorological data available and frequency Rainfall: Daily Air temperature: Daily Soil temperature: Daily at 0,5,10,15,20 7 40 cm depth Wind speed: Daily Net Radiation: Daily Sun hours: Daily Relative humidity: Daily Potential evapotranspiration: Daily measured/calculated by Open pan evaporation DATA AVAILABLE IN ELECTRONIC FORMAT Yield data available in electronic format from 1988 Nitrogen content of offtake data available in electronic format from 1988 Total soil carbon data available in electronic format from 1988 Data available in electronic format for total soil nitrogen from 1988 Data available in electronic format for soil ammonium nitrogen from 1988 Data available in electronic format for soil bulk density from 1988 This information was compiled for the GCTE-SOMNET Database, Pete Smith, Pete Falloon, David Powlson, and Jo Smith.
