ABSTRACT Acidic soils are susceptible to nutrient insufficiencies and imbalances. Combined application of biochar and other organic amendments is a renowned strategy for ameliorating acid soils and enhancing soil fertility. The incubation experiment investigated the effect of biochar and poultry litter on chemical properties and nutrients availability of acidic soil. 400 g of soil was thoroughly mixed with the following treatments: corn straw biochar at the rate equivalent to 15 t/ha (B15), 30 t/ha (B30), poultry litter at the rate equivalent to 10 t/ha (PL), poultry litter plus biochar at 15 t/ha (PL+ B15), poultry litter plus biochar at 30 t/ha (PL + B30) with the control (CK) to represent, T1, T2, T3, T4, T5, and T6, respectively. These were incubated in a climate box at 25°C and 80% field capacity for 90 days. Soils were sampled destructively at 30, 60, and 90 days for analysis. Results showed that combined application of biochar and poultry litter increased concentrations of % total organic carbon (% TOC), % organic matter (% OM), electrical conductivity (EC), % total nitrogen (% TN), Phosphorus (P), reduced Iron (Fe) concentrations, and carbon to nitrogen (C: N) ratio. Poultry litter enhanced exchangeable acidity, pH, effective cation exchange capacity (ECEC), and exchangeable cations except for Potassium (K), biochar alone reduced zinc (Zn) concentration. In conclusion, the combined application of poultry litter and biochar could effectively ameliorate acidic soil, enhance soil fertility, and maintain good soil health.

生物炭和家禽垫料施用对酸性土壤化学性质和养分有效性的影响

摘要酸性土壤易受养分不足和不平衡的影响。生物炭和其他有机改良剂的联合应用是改善酸性土壤和提高土壤肥力的著名策略。孵化实验研究了生物炭和家禽垫料对酸性土壤化学性质和养分有效性的影响。将 400 克土壤与以下处理彻底混合:玉米秸秆生物炭的用量相当于 15 吨/公顷(B15)、30 吨/公顷(B30),家禽垫料的用量相当于 10 吨/公顷(PL) , 家禽垫料加生物炭 15 t/ha (PL+ B15), 家禽垫料加生物炭 30 t/ha (PL + B30) 以对照 (CK) 表示,T1、T2、T3、T4、T5 和 T6 , 分别。这些在 25°C 和 80% 田间容量的气候箱中培养 90 天。在 30、60 和 90 天时对土壤进行破坏性采样以进行分析。结果表明,生物炭和家禽垫料的联合应用增加了总有机碳百分比 (% TOC)、有机物质百分比 (% OM)、电导率 (EC)、总氮百分比 (% TN)、磷 (P) 的浓度,降低了铁 (Fe) 浓度和碳氮 (C: N) 比率。家禽垫料增强了可交换酸度、pH 值、有效阳离子交换容量 (ECEC) 和可交换阳离子(钾 (K) 除外),单独的生物炭降低了锌 (Zn) 浓度。综上所述,家禽垫料与生物炭联合施用可有效改善酸性土壤,提高土壤肥力,保持土壤健康。结果表明,生物炭和家禽垫料的联合应用增加了总有机碳百分比 (% TOC)、有机物质百分比 (% OM)、电导率 (EC)、总氮百分比 (% TN)、磷 (P) 的浓度,降低了铁 (Fe) 浓度和碳氮 (C: N) 比。家禽垫料增强了可交换酸度、pH 值、有效阳离子交换容量 (ECEC) 和可交换阳离子(钾 (K) 除外),单独的生物炭降低了锌 (Zn) 浓度。综上所述,家禽垫料与生物炭联合施用可有效改善酸性土壤,提高土壤肥力,保持土壤健康。结果表明,生物炭和家禽垫料的联合应用增加了总有机碳百分比 (% TOC)、有机物质百分比 (% OM)、电导率 (EC)、总氮百分比 (% TN)、磷 (P) 的浓度,降低了铁 (Fe) 浓度和碳氮 (C: N) 比。家禽垫料增强了可交换酸度、pH 值、有效阳离子交换容量 (ECEC) 和可交换阳离子(钾 (K) 除外),单独的生物炭降低了锌 (Zn) 浓度。综上所述,家禽垫料与生物炭联合施用可有效改善酸性土壤,提高土壤肥力,保持土壤健康。家禽垫料增强了可交换酸度、pH 值、有效阳离子交换容量 (ECEC) 和可交换阳离子(钾 (K) 除外),单独的生物炭降低了锌 (Zn) 浓度。综上所述,家禽垫料与生物炭联合施用可有效改善酸性土壤,提高土壤肥力,保持土壤健康。家禽垫料增强了可交换酸度、pH 值、有效阳离子交换容量 (ECEC) 和可交换阳离子(钾 (K) 除外),单独的生物炭降低了锌 (Zn) 浓度。综上所述,家禽垫料与生物炭联合施用可有效改善酸性土壤,提高土壤肥力,保持土壤健康。
