Abstract EN
Chinese hickory (Carya cathayensis), a popular nut food tree species, is mainly distributed in southeastern China.
A field study was carried out to investigate the effect of long-term intensive management on fertility of soils under a C.
cathayensis forest.
Results showed that after 26 years’ intensive management, the soil organic carbon (SOC) content of the A and B horizons reduced by 19% and 14%, respectively.
The reduced components of SOC are mainly the alkyl C and O-alkyl C, whereas the aromatic C and carbonyl C remain unchanged.
The reduction of active organic matter could result in degradation of soil fertility.
The pH value of soil in the A horizon had dropped by 0.7 units on average.
The concentrations of the major nutrients also showed a decreasing trend.
On average the concentrations of total nitrogen (N), phosphorus (P), and potassium (K) of tested soils dropped by 21.8%, 7.6%, and 13.6%, respectively, in the A horizon.
To sustain the soil fertility and C.
cathayensis production, it is recommended that more organic fertilizers (manures) should be used together with chemical fertilizers.
Lime should also be applied to reduce soil acidity.
