Integrated Plant Nutrient System (IPNS) is practiced worldwide to maintain soil quality. Two field experiments were conducted in 2019 and 2020 in acidic and charland soils to assess the impact of different manures, viz., poultry manure (PM), vermicompost (VC), compost (OF), rice husk biochar (RHB), poultry manure biochar (PMB)-based IPNS, and dolomite over control on productivity and nitrogen use efficiency (NUE) of the Mustard-Boro-Transplanted Aman and Maize-Jute-Transplanted Aman cropping patterns, and on soil properties. The experiments were laid out in a randomized complete block design with four replications. The results showed that IPNS treatments significantly improved soil aggregate properties and total nitrogen in acidic soil, and bulk density in charland soil. In both years, IPNS treatments increased system productivity from 55.4 to 82.8% in acidic soil and from 43.3 to 115.4% in charland soil over that of control. IPNS and dolomite treatments increased nitrogen uptake from 35.5 to 105.7% over that of control and NUE in both soils in 2019 and 2020. PMB- and OF-based INPS treatments exhibited superior performances in both soils, and the impact was more prominent in 2020. Therefore, PMB- and OF-based IPNS can be recommended for maximizing system productivity and NUE with concurrent improvement of physicochemical properties of acidic and charland soils.
综合植物营养系统（IPNS）在全球范围内被用于维持土壤质量。2019年和2020年在酸性土壤和滨海沙地土壤上进行了两项田间试验，以评估不同肥料，即家禽粪便（PM）、蚯蚓堆肥（VC）、堆肥（OF）、稻壳生物炭（RHB）、基于家禽粪便生物炭（PMB）的IPNS以及白云石相对于对照，对芥菜-冬播移栽稻和玉米-黄麻-冬播移栽稻种植模式的生产力和氮素利用效率（NUE）以及土壤性质的影响。试验采用随机完全区组设计，重复四次。结果表明，IPNS处理显著改善了酸性土壤的团聚体性质和总氮含量，以及滨海沙地土壤的容重。在这两年中，与对照相比，IPNS处理使酸性土壤的系统生产力提高了55.4%至82.8%，滨海沙地土壤提高了43.3%至115.4%。2019年和2020年，IPNS和白云石处理使两种土壤中的氮素吸收量比对照提高了35.5%至105.7%，并提高了氮素利用效率。基于PMB和OF的INPS处理在两种土壤中均表现出优异的性能，且在2020年影响更为显著。因此，基于PMB和OF的IPNS可被推荐用于最大化系统生产力和氮素利用效率，同时改善酸性土壤和滨海沙地土壤的物理化学性质。
