Oil palm fibres are easy to degrade, eco-friendly in nature and once composted, they can be categorized under nutrient-enriched biocompost. Biocompost is not only a good biofertilizer but also a good biocontrol agent against soil-borne pathogens. In this research, experimental works on the composting of empty fruit bunches (EFB) from the oil palm industry were conducted using two potential strains. Analysis of pH initially found the soils to be slightly acidic. However, after composting, the soils were found to be alkaline. propagules increased by 72% in the soils compared to other fungi. Soil electrical conductivity was found to be 50.40 μS/cm for compost A, 42.10 μS/cm for compost B and 40.11 μS/cm for the control. The highest C:N ratio was obtained for compost A at 3.33, followed by compost B at 2.79, and then the control at 1.55. The highest percentages of nitrogen (N), phosphorus (P), and potassium (K) were found in compost A (0.91:2.13:6.68), which was followed by compost B (0.46:0.83:5.85) and then the control (0.32:0.26:5.76). Thus, the biocomposting of oil palm fibres shows great potential for enhancing soil micronutrient, plant growth performance, and crop yield production.
油棕纤维易于降解,本质上对环境友好,一旦制成堆肥,它们可归类为富含养分的生物堆肥。生物堆肥不仅是一种优质生物肥料,也是一种防治土壤传播病原体的良好生物防治剂。在本研究中,利用两种潜在菌株对油棕产业的空果串(EFB)进行了堆肥实验。pH值分析最初发现土壤呈微酸性。然而,堆肥后发现土壤呈碱性。与其他真菌相比,土壤中的繁殖体增加了72%。发现堆肥A的土壤电导率为50.40 μS/cm,堆肥B为42.10 μS/cm,对照为40.11 μS/cm。堆肥A的C:N比最高,为3.33,其次是堆肥B,为2.79,然后是对照,为1.55。堆肥A中氮(N)、磷(P)和钾(K)的百分比最高(0.91:2.13:6.68),其次是堆肥B(0.46:0.83:5.85),然后是对照(0.32:0.26:5.76)。因此,油棕纤维的生物堆肥在提高土壤微量营养素、植物生长性能和作物产量方面显示出巨大潜力。
