原始语种摘要: A study was conducted to investigate the effect of multipurpose tree species namely Prosopis cineraria , Acacia senegal and Tecomella undulata on the physical and chemical properties of soils representing Typic Haplocambids. The plantations of Prosopis cineraria and Acacia senegal were even aged, while that of Tecomella undulata was relatively young. The soils had an overall low status of SOC (<0.50%), low to medium P (8.2–15.7 kg/ha) and medium to high K (276–498 kg/ha). There was improvement in water holding capacity and decrease in surfacesoils bulk density under these tree species when compared to field without plantation. Slight decrease in pH of the soils under these tree species was noticed, whereas changes in EC were not appreciable. Significant improvement in soil organic carbon...
