Long-term effects of applying pyrolysed [biochar (BC)] or un-pyrolysed [rice straw (RS) and farmyard manure (FYM)] organic materials individually or their co-application on soil irrigated with saline water (SW) is not well known. An incubation study was conducted for 52 weeks with soil collected from plots irrigated with water of variable electrical conductivity (EC) [SW of EC 10 and 15 dS m^-1 and canal water (CW) of EC 0.3 dS m^-1]. The soil samples were amended with different quality organic materials (BC, FYM, or RS) and soil respiration was recorded at regular intervals. The incubated soil was destructively harvested on days 1, 15, 45, 90, 180, and 365 for analysis of soil parameters like microbial biomass C, water-extractable organic C, soil organic C, pH, and EC. Over 52 weeks of incubation, compared with non-saline soil, cumulative respiration (CR) was reduced by 39–57% with increasing soil salinity. However, individual application of BC, RS, and FYM or their co-application exhibited a beneficial effect on CR at all the soil salinity levels. Among different organic materials, RS amended soil showed maximum carbon (C) loss per g of C added whereas, it was minimum in BC treatment. On the other hand, when BC was co-applied with RS (BC+RS) or FYM (BC+FYM), loss of C per g of C added from the amended soil were increased by 9–16% and 6–13% (from 3‐7% in sole BC amended soil) respectively, even though the input of C in BC+RS and BC+FYM were 88% and 56% more than the individual BC amended soil. The study showed that both pyrolysed and un-pyrolysed organic materials can override the negative effects of salinity on soil microbial activity when applied individually or in combination. In addition, co-application of BC with un-pyrolysed organic materials (FYM or RS) will be more beneficial for soil C stabilization than their individual application.

单独施用热解 [biochar (BC)] 或未热解 [稻草 (RS) 和农家肥 (FYM)] 有机材料或它们在用盐水 (SW) 灌溉的土壤上共同施用的长期效果不佳已知。对从用可变电导率 (EC) [EC 的 SW 为 10 和 15 dS m ^{-1 的}水以及 EC 0.3 dS m ^{-1 的}运河水 (CW)灌溉的地块收集的土壤进行了 52 周的孵化研究]。用不同质量的有机材料（BC、FYM 或 RS）修正土壤样品，并定期记录土壤呼吸。在第 1、15、45、90、180 和 365 天对孵化的土壤进行破坏性收获，用于分析土壤参数，如微生物生物量 C、水可提取有机 C、土壤有机 C、pH 和 EC。经过 52 周的孵化，与非盐渍土壤相比，随着土壤盐分的增加，累积呼吸 (CR) 降低了 39-57%。然而，单独施用 BC、RS 和 FYM 或它们的共同施用对所有土壤盐度水平的 CR 都表现出有益的影响。在不同的有机材料中，RS 修正的土壤表现出最大的碳 (C) 损失，而每克添加的碳，在 BC 处理中最小。另一方面，当 BC 与 RS (BC+RS) 或 FYM (BC+FYM) 共同应用时，尽管在 BC+RS 和 BC 中输入 C +FYM 比单独的 BC 改良土壤多 88% 和 56%。研究表明，热解和未热解的有机材料单独或组合使用时，都可以抵消盐分对土壤微生物活动的负面影响。此外，BC 与未热解的有机材料（FYM 或 RS）的共同应用将比单独应用更有益于土壤碳的稳定。研究表明，热解和未热解的有机材料单独或组合使用时，都可以抵消盐分对土壤微生物活动的负面影响。此外，BC 与未热解的有机材料（FYM 或 RS）的共同应用将比单独应用更有益于土壤碳的稳定。研究表明，热解和未热解的有机材料单独或组合使用时，都可以抵消盐分对土壤微生物活动的负面影响。此外，BC 与未热解的有机材料（FYM 或 RS）的共同应用将比单独应用更有益于土壤碳的稳定。
