| 英文摘要 | To determine the effect of addition of acidulated pig bio char on phosphorus (P) availability and fractionation in soils,an incubation experiment was carried out using a randomized complete block design having five treatments:an untreated control (ck),acidulated pig biochar,raw pig biochar,single superphosphate,and calcium magnesium phosphate,with three replications.Each amendment was mixed with soil at 0.1% (w/ w) and placed in a plastic pot.Soil samples were taken from each pot after a 210-day incubation period to assess P fractionation using modified Hedley's sequential extraction procedures.A correlation analysis was also included.Results showed that,compared to ck,electrical conductivity (EC) of the soil increased (P<0.05) with raw pig biochar (24%) and acidulated pig biochar treatments (14%),but there was no significant effect on soil pH.Compared to ck,with the same application rate acidulated biochar was more effective (P<0.05) than pig biochar for improving the proportions of soil labile and moderately labile phosphorus;whereas,no significant differences in these P proportions between the acidulated biochar and the fertilizer treatments were found.Compared to ck,the percentage of labile P pools significantly (P<0.05) increased in all treatments,but there were no significant differences between biochar and fertilizer treatments.In comparison with ck,moderately labile P pools increased (P<0.05) in biochar (36.2%) and fertilizer treatments (77.2%) in the following order:acidulated pig biochar > superphosphate > calcium magnesium phosphate > raw pig biochar.The percentage of stable P pools decreased (P<0.05) with addition of the amendments,and the proportion of the stable P pools was negatively correlated to the proportion of labile (R~2=0.86,P<0.01) and moderately labile (R~2=0.94,P<0.01) P pools.The acidulated pig biochar treatment significantly (P<0.05) increased the concentration of all P fractions and maintained a relatively low proportion of stable P in the treated soil.In conclusion,with significant differences in soil P concentrations and fractionations between acidulated pig biochar and chemical P fertilizers treatments tested,it would be potentially viable to use acidulated pig biochar as an alternative P fertilizer and substitute for superphosphate and calcium magnesium phosphate in agricultural production. |
