英文摘要Fertility degradation of Mollisols affects world food security. Understanding the degradation mechanisms of Mollisols is essential in order to restore the soils' productivity. A long-term field experiment was conducted to assess soil phosphorus (P) concentrations and fractions in a Mollisol at its early development stage under different cropping systems in Northeast China Parent material (PM) and mature Mollisol (OM) were used for comparison. Organic P (Po) concentrations under natural fallow (Pnat), alfalfa (Medicago sativa L.) (PA and soybean-maize (S-M) rotation without fertilizer application (PCS-F) increased by 68-74% after 10 years. S-M rotation with mineral fertilizer (PCS + F), organic matter amendment (PCS + F + OM), or crop straw return (PCS + F + BM) increased Po concentrations by 74.1-108 mg kg(-1), which is equivalent to 33% of total Po in the OM; and increased Ca-2-P, Ca-8-P, Al-P and Fe-P concentrations by 0.9-1.3, 7.1-8.8, 2.1-2.7 and 1.6-1.7 times, respectively. 67% of the applied fertilizer P was transformed to Pi for the treatments with chemical fertilizer. The results indicate that return of crop residue combined with chemical fertilizers enhances the accumulation of P in soils at their early development stage, which has important implications for the fertility restoration of a Mollisol in Northeast China and elsewhere in the world.
