Long-term static fertilization - Skierniewice

This experiment has been added by the GLTEN Curators using existing published sources.
Objective
Evaluation of different organic and mineral fertilization effect on crops and environment in different crop rotation systems.
Description
A series of experiments were established between 1922 and 1925 to compare different crop rotations with and with out farmyard manure and with various combinations of mineral fertilizer. In this entry, the design periods summarise the four main crop rotation experiments.

Design period: Arbitrary rotations without and without legumes (1922—)

Description
The Arbitrary rotations without legumes experiments were established on the 'A' fields and test different combinations of mineral fertilizer. descriptions of the rotation sequences have not been found in the published literature, but crops used in the rotation have been identified. FYM was introduced as an experiment factor in 1992, and mineral fertilizer rates were increased in 1976. The experiment fields are sited on both strongly and slightly acidic soils.
Design description
The project website gives a detailed description of which experiment factors are applied in combination. Mineral fertilizers are applied in the combinations: NPK, PK, PN and KN

nitrogen fertilizer exposure
N either applied or not and in two different forms.
N-sulfate  (90 kgN/ha)
Chemical form: ammonium sulfate
30 kg N ha-1 from 1923-1975. The ammonium sulfate treatment is only used in combination with the rotations without legumes.
ammonium nitrate  (90 )
Chemical form: ammonium nitrate
30 kg N ha-1 from 1923-1975
phosphate fertilizer exposure
P  (26 kgP/ha)
13 kg P ha-1 from 1923-1975
potassium fertilizer exposure
K  (91 kgK/ha)
26 kg K ha-1 from 1923-1975
natural fertilizer exposure
farmyard manure
1992—
Chemical form: farmyard manure
FYM treatment is only used in combination with the rotations without legumes.
liming exposure
Ca  (1.6 t/ha)
Application frequency: Every 4 years
Except for the combination CaNPK, Ca is not used in combination with N treatments applied as ammonium sulfate.

Design period: 5-course rotation (1924—)

Description
The 5-course rotation experiment was established on the 'E' fields and is replicated 5 times. FYM is applied to all plots at 30 t ha-1 every four years. Form of nitrogen is not an experiment factor. All plots are limed except for one NPK factor level combination which receives no lime.
