| Summary, etc. | Earthworm densities have been regarded as reliable indicators of soil<br/>health. A long-term field experiment was conducted in two sites (15% and 25%<br/>slope) to compare the effects of manual and chemical weeding (using paraquat<br/>and glyphosate) and determine other factors that may affect earthworm<br/>populations in a banana plantation. Based on four years of field observation, no<br/>significant difference in earthworm count between manual and chemical plots<br/>(15% slope: F-ratio: 0.96, p = 0.43; 25% slope: F-ratio: 14.18, p = 0.06) were<br/>observed. The earthworm species composition was found to differ between the<br/>two sites. The 15% site tends to have a higher earthworm population compared<br/>to the 25%-slope site, likely because of the former’s higher soil organic matter<br/>content. Earthworm populations were on a declining trend in both treatments<br/>for both sites, but regression analyses show these trends to be insignificant.<br/>Rainfall, organic mulch, and weed cover were not significantly correlated with<br/>the earthworm counts. However, the declining pH in both sites could help<br/>explain the decline in earthworm populations. Pontocolex corethrurus showed<br/>significant avoidance response to normal glyphosate concentrations (8.055 ×<br/>10–3 mL per 350 g soil) (p = 0.03), but not to paraquat (1.5 × 10–3 g per 350 g<br/>soil) (p = 0.55). Experiments suggest that both weed management treatments<br/>do not pose a significant threat to earthworms under the conditions studied.<br/>The negative effect of declining pH needs further study. |
