“…It is often considered that increasing plant species diversity could lead to the delivery of diverse soil ecosystem services. Only three of the 22 studies evaluated earthworm abundance under CC mixes within the same experiment (Hmazaev et al, 2007; Crotty & Stoate, 2019; Ghahremani et al., 2021; Table 1). These few studies show CC mixes do not outperform single species nor an increase in the number of species within a CC mix results in increased earthworm abundance.…”

Earthworms are key to the engineering of soil ecosystem services. However, how cover crops (CCs) influence these ecosystem engineers has not been widely discussed. This paper reviews (a) CC effects on earthworm abundance, biomass, diversity, and related soil ecosystems services and (b) factors affecting CC effects on earthworms. A review of existing literature (through 29 May 2022) found 22 CC studies on earthworm abundance and 10 on earthworm biomass, but studies on earthworm diversity were few. Cover crops increased earthworm abundance in 13 of 22 studies, increased biomass in five of 10 and had no effect in the rest of studies compared with no CCs. The change (Δ increase) was 11 to 535 earthworms m -2 and 11 to 44 g of earthworm biomass m -2 . Cover crop effects on earthworm diversity are mixed. Earthworm abundance was more responsive to CCs than soil C and physical properties, suggesting earthworm abundance should be included as a sensitive measurement in soil health status. Cover crops with low C/N under no-till or reduced-till systems promote earthworm abundance relative to CCs with high C/N under conventionally tilled systems. Cover crop mixtures do not increase earthworm abundance more than monocultures. Earthworm abundance generally increases with increasing precipitation (r = 0.45; p = .025) and temperature (r = 0.36; p = .10).Overall, CCs increase earthworm abundance but have mixed effects on earthworm biomass and diversity, although more data from different CC management scenarios and climates are needed for more robust conclusions. INTRODUCTIONMaintaining or improving the health and ecosystem services of soils under a growing world population and declining environmental quality is essential. Halting soil degradation, restoring degraded soils, and developing resilient and healthy soils are priorities for the continued delivery of essential ecosystem services from soils. Such services include climate regulation, C sequestration, nutrient cycling, and improvement in water quality, soil biodiversity, and wildlife habitat, among others (Adhikari & Hartemink, 2016; Abbreviations: CC, cover crop.

The mother tongue is as sacred as the Motherland, parents and family are precious to everyone. When a child is born, he is given a name in his mother tongue, Allah is said in his mother tongue, and he speaks words in his mother tongue. The notion of the mother tongue is therefore a sacred value instilled in the blood of each of us. He plays an important role in finding a small place in our society, in shaping us into mature people who will benefit the people. The mother tongue is an example of the unity and solidarity of the nation, its pride and spirit.
