摘要

Oil palm (Elaeis guineensis) is widely cultivated and exported due to its high global demand. However, poor soil fertility can greatly reduce oil palm production. Repetitive soil exploitation and excessive use of chemical fertilizers and pesticides degrade soil quality and introduce harmful substances. This study aims to characterize Paenibacillus spp. and assess its potential as a biofertilizer to enhance soil fertility in Paloh Jenang oil palm fields. Molecular techniques, specifically 16S primers, were employed to identify Paenibacillus spp. Soil samples from favorable and non-favorable areas of the plantation were collected and treated with Paenibacillus spp. granules. The effects on soil fertility were measured by evaluating soil pH, electrical conductivity (EC), and nutrient composition using CNS Analysis and Inductively Coupled Plasma Optical Emission Spectroscopy (ICP–OES). Statistical analysis, including ANOVA, revealed that Paenibacillus spp. improved soil fertility, with significant increases in pH and EC. Key nutrients such as total nitrogen, phosphorus (P), potassium (K), magnesium (Mg), calcium (Ca), and sulfur (S) were higher in treated soils compared to the control. Notably, P2 bacteria showed a significant pH increase after one month of treatment. The study concludes that Paenibacillus spp., a Gram-positive bacteria, exhibits strong potential as a biofertilizer, improving soil fertility and enhancing oil palm growth. This research underscores Paenibacillus spp.'s role in boosting oil palm yields while promoting environmental sustainability.
