The role of earthworms in organic matter cycles,imal residues may be decomposed by the microflora but much organic matter, particularly the tougher plant leaves, stems and root material, does not breakdown without first being disintegrated by soil animals and acted upon by enzymes in their intestines. Earthworms have an important role in this ini作者: jumble 時(shí)間: 2025-3-22 11:13 作者: 錯(cuò)事 時(shí)間: 2025-3-22 15:28 作者: 無(wú)王時(shí)期, 時(shí)間: 2025-3-22 17:24

He concluded that sixteen sample units of an area of 1/16 m. taken to a depth of 20 cm gave an adequate estimation of a population of medium-sized species. For larger worms and deeper samples, a larger area of sample was required.作者: transplantation 時(shí)間: 2025-3-23 08:50 作者: STEER 時(shí)間: 2025-3-23 10:20 作者: magnanimity 時(shí)間: 2025-3-23 17:45 作者: Digest 時(shí)間: 2025-3-23 18:41 作者: 澄清 時(shí)間: 2025-3-23 23:39 作者: MIRE 時(shí)間: 2025-3-24 05:09

Effects of agriculture on earthworm populations,e land in late spring did not decrease earthworm numbers. Indeed, it would be surprising if mechanical damage by ploughing was very important, because the plough merely turns the soil over, and probably has little effect on worms with deep burrows.
