摘要: The biological (macrofauna and mesofauna), physical (size) chemical (nutrient availability) properties of Lumbricus terrestris middens were studied on a minimum tillage field trial amended with farmyard manure, compost or unamended treatments. Results showed that herbivorous-type interactions wheat crop leaves common. Midden microhabitats containing these fresh significantly enhanced by up to 2.8-fold in mesofauna (springtails, enchytraeidae, mites, millipedes) abundance. plots manure had (p < 0.05) more endogeic earthworms than control plots. Further, found larger, being twice the size (20.6 ± 1.7 g dry weight) plots, demonstrating improves midden microhabitat quality. Middens enriched extractable plant nutrients including P, K, S Mn.
