Other claims from this paper (10)

Intervention effect In treatment NPKM, rice yield across 28 years was maintained at the highest level among the fertilization treatments.
Intervention effect In treatment NPK, rice yield showed a decreasing trend and was lower than in other fertilization treatments.
Intervention effect Fertilization increased soil organic matter, total N and alkaline-hydrolysable N contents and rice yield.
Intervention effect Fertilization with manure increased soil organic matter significantly compared with chemical fertilizers only.
Intervention effect With manure only or combined with chemical fertilizers, soil OM content increased rapidly in the first 16 years and then fluctuated around 29.42-39.32 g x kg(-1).
Intervention effect Under fertilization, soil total N content showed a rapid increase in the first 8 years.
Intervention effect The increment of soil total N content was highest in treatment NPKM.
Intervention effect Soil alkaline-hydrolysable N content had a slower increase in the first 12 years, at 0.66-2.25 mg x kg(-1) x a(-1).
Intervention effect In 1994-1998, soil alkaline-hydrolysable N content had a quicker increase, at 6.45-32.45 mg x kg(-1) x a(-1).
Recommendation Organic fertilization is the key measure to stably improve soil properties and productivity of red paddy soils and to sustain rice production.
