Soil Changes Over Time Within a Dry Meadow, Long Term Soil Organic Matter Study, RussiaEntry ID: RAS.SCG.DryMeadow
Abstract: This experiment began in 1965. The present cutting meadow was formed
on land that was ploughed in 1890-1900, then used only for hay harvest
without any treatment. The soil at the site developed on loess-like
loams, underlain by moraine. The climatic region of the sit falls
within the cold temperate boreal boudaries. The studied soil has no
equivalents in USDA, FAO. Under the Russian ... classification system
these soils are called Soddy soils. All information about this soil
can be found in Yakimenko E (1987) Pochvovedenie, 1987 no. 5 (English
The experiment consists of straw incorporation & FYM on an arable,
meadow cut for hay. The measurements made (data available),
methodology, and frequency are as below:
a) Vegetation measurements made and frequency
Yield: Biweekly in summer, otherwise monthly.
Total above-ground dry matter: biweekly in summer, otherwise monthly.
Total dry matter offtake: biweekly in summer, otherwise monthly.
Carbon content of offtake: biweekly in summer, otherwise monthly.
Nitrogen content of offtake: biweekly in summer, otherwise monthly.
b) Soil sampling
Details of soil sampling method: Five-ten sections were made.
Samples taken according to genetic horizons by auger (100 cu cm) from
every section. In the transect, soil samples were taken for every 5 cm
of depth, and every 20 cm along its length. Soil is separated into
Details of measuring depths and soil layers: Asod 1-5 cm; A1
10-15,20-25 cm; B1 30-40 cm; B2 50-60,70-80 cm; BC 100-110 cm.
c) Soil measurements made and frequency
Total carbon: Once every 3-5 years
Method of measuring total carbon: Acid-dichromate digestion
Biomass carbon: Once only
Method of measuring biomass carbon: Burning to ashes
Carbon measurements in other organic matter fractions: Once every
Method of measuring carbon in other organic matter fractions:
Humic and fulvic acids were extracted by treatment with
Na4P2O7. Carbon contentwas determined by acid-dichromate digestion of
Total nitrogen: Every 3-5 years
Method of measuring total nitrogen: By treatment with H2SO4.
Soil bulk density or weight: Every 3-5 years.
Method of measuring soil bulk density or weight: Bulk density was
determined by excavation of a core with metal glass. Soil weight
(specific gravity) was determined by pycnometers.
Other nutrients: pH (salt extract), soluble P.
Atmospheric inputs: Chemical composition of atmospheric deposits
(rain and snow) was determined in the open plots and was taken into
account when soil properties were discussed.
Other measurements: Content of exchangeable cations in the soil.
Total amount of
SiO2,Al2O3,FeO3,MnO,MgO,CaO,Na2O,K2O,P2O5 and Fe and Mn content in
the acid extract (1H H2SO4) in the soil, grain-size
compound, amount of Fe-Mn neoformations and their compound bulk
density and soil weight; water permeability; pH (water extract).
d) Details of the meteorological station
Nearest meteorological station to the site: Nebolsin (most
meteorological data comes from the Moscow University Meteorological
e) Meteorological data available and frequency
Rainfall: Monthly in the growing season. Also total snowfall in summer.
Air temperature: Monthly in the growing season

Quality a) Details of the plots
Width of smallest plot is 50 m
Length of smallest plot is 100 m
Slope: 3-4% . Shape: Uniform
Width of Discard Strip around plot: 10-20 m
b) Details of replication, randomization and controls
There are at least 5 replicates in the experiment. The experiment has
... a randomized plot design. The experiment has a restricted randomized
plot design. Soil was sampled from sections (in this investigation)
which were distributed in chess order. Earlier replicates distributed
by random plot design. The control plot is a forest (pine) ecosystem
of the same age as the dry meadow . Standard statistical tests were
used: Mean values, error of mean values, dispersion, coefficient of
