Commercial turfgrass cultivation is one of the main ornamental industries world-wide; however, successive turfgrass sod cutting from the same site removes surface soil, leading to a decline in soil organic matter, impairment of soil fertility and degradation of environment. The present study was aimed to investigate the applicability of poultry abattoir sludge compost (PASC) and biochar (BC) on the establishment of turfgrass by evaluating plant growth performance and mitigation of soil loss by organic waste amendments. The experimental study was designed on the soil which had originally low-organic matter content and previously used as a turfgrass sod harvested site in a sandy loam soil. Incorporation of PASC to soil improved the physicochemical properties in terms of bulk density (BD), water holding capacity (WHC), cation exchange capacity (CEC), pH, total nitrogen, total organic carbon (TOC), and organic matter (OM) by 37 (±2)%, 45 (±3)%, 55 (±3)%, 21 (±2)%, 48 (±2)%, 90 (±10)%, and 96 (±4)%, respectively. PASC-amended treatments enhanced the turfgrass growth rate more than the BC due to its increased nutrient availability. Incorporation of 100 Mg ha (mega gram per hectare) PASC in surface soil with or without BC decreased the mineral soil removal rate by half of the respective soil (control) treatments. The results of the present study confirmed the utilization of PASC and BC as promising agro-industrial-based fertilizers in turfgrass sod production for sustainable soil and nutrient management.
商业草坪草种植是世界范围内主要的观赏产业之一；然而，在同一地点连续切割草坪草草皮会去除表土，导致土壤有机质减少，肥力下降，环境恶化。本研究旨在通过评估有机废物改良剂对植物生长性能和土壤侵蚀的缓解作用，探讨家禽屠宰场污泥堆肥（PASC）和生物炭（BC）在草坪草建立中的应用。该实验研究设计在原本有机质含量低且曾用作草坪草草皮收获地的沙壤土上进行。PASC 施入土壤可提高土壤物理化学性质，容重（BD）、持水能力（WHC）、阳离子交换能力（CEC）、pH 值、总氮、总有机碳（TOC）和有机质（OM）分别增加 37（±2）%、45（±3）%、55（±3）%、21（±2）%、48（±2）%、90（±10）%和 96（±4）%。由于 PASC 增加了养分的有效性，PASC 处理比 BC 处理更能提高草坪草的生长速度。在表层土壤中添加 100 Mg ha（兆克每公顷）PASC 并添加或不添加 BC 可将矿物土壤去除率降低到各自土壤（对照）处理的一半。本研究结果证实了 PASC 和 BC 作为有前途的农业工业肥料在草坪草草皮生产中的应用，可实现可持续的土壤和养分管理。
