Other claims from this paper (7)
- Observation Nitrogen sources did not differ significantly in the evaluated soil properties after 30 annual applications.
- Intervention effect Long-term nitrogen fertilization significantly lowered surface soil pH, especially at higher rates.
- Association Soil pH decreased with time and was significantly related to total nitrogen applied.
- Intervention effect Nitrogen fertilization decreased exchangeable base cations.
- Association Exchangeable Al and Al saturation increased with nitrogen rate and were inversely related to soil pH.
- Observation Wheat yield was not significantly reduced until 1995 despite pH falling below 5.0 by 1980.
- Association Yield reductions during 1995–2002 coincided with the largest pH change.
