“…Soil acidity is one of the major crop production constraints in Ethiopia [8], covering 43% of cultivated land [9,10], of which 28% is strongly acidic. Soil acidification is a natural process that might be aggravated by human agricultural activities such as the removal of plant and animal products and leaching of excess nitrate addition of some nitrogen-based fertilizers [11].…”

“…With accelerated urbanization and industrialization, for instance, soil heavy metal pollution becomes more and more severe and widespread [ 3 ], which changes the soil microbial community [ 4 ], affects crop growth [ 5 ], harms the agricultural environment [ 6 ] and consequently threatens the health of humans [ 7 ]. Soil acidification is a serious global environment problem in agriculture production [ 8 ] and the acidified soil area continues to expand due to the massive discharge of acid-causing substances [ 9 ], irrational use of chemical fertilizers [ 10 ] and intensive agricultural production [ 11 ]. These serious pollutions alter soil physicochemical properties and quality, limit nutrient supplies to plants, affect microbial community structure and interactively alter the biological activities and metabolic process of soil animals.…”

The earthworm, as a soil engineer, plays highly important roles in the soil ecosystem for shaping soil structure, promoting soil fertility, regulating microbial community composition and activities and decomposing soil pollutants. However, the research progresses on this important soil fauna have rarely been reviewed so far. Therefore, we conducted a bibliometric analysis of the literature published during 1900–2022, which was collected from the Web of Science Core Collection (WoS). The results showed that three periods (1900–1990, 1991–2005 and 2006–2022) could be identified in terms of the intensity of publications on the topic, and the number of publications kept increasing since 2006. The United States produced the highest publication record at the country scale, whereas Chinese Academy of Sciences was the most productive institution. Chinese institutions and authors played an active and prominent role during 2018–2022. Soil Biology & Biochemistry was the most popular journal for the topic-related research. In these publications, Professor Lavelle P was the most influential author. Based on a citation network of the top 50 cited papers, four hotspots were identified, i.e., the ecological effects of earthworms, the impact of agricultural activities on earthworms, earthworm ecotoxicology and earthworm invasion. Moreover, “impact”, “biodiversity”, “oxidative stress”, “diversity”, “response”, “Eisenia fetida” and “exposure” were the emerging and active topics in recent years. This study can help us to better understand the relevant subject categories, journals, countries, institutions, authors and articles and identify the research hotspots and emerging trends in the field of soil earthworm research.

“…Soil acidity is a serious issue in agricultural production, afecting approximately 50% of arable lands worldwide [1,2]. Soil acidity can reduce cereal grain yield by as much as 50%, and in extreme cases, yields can be reduced to zero [3][4][5].…”

Soil acidity is one of the major crop production constraints in the highlands of Ethiopia. Liming is becoming a common practice to amend soil acidity, but its effects on soil properties, crop yield, and farm income are not well studied. In this study, an on-farm liming experiment was conducted for two consecutive years (2020-2021) on acidic Nitisols (pH < 5.5) in Southern Ethiopia. The experiment consisted of six liming rates (control, 2.74, 4.11, 5.48, 6.85, and 8.22 t·ha−1) laid out in a randomized complete block design with three replications. Soil, agronomic, and economic data were collected in 2020 and 2021 cropping seasons and analyzed. The application of lime in the ranges of 2.74–8.22 t·ha−1 increased soil pH by 0.46–1.25 units and reduced exchangeable acidity by 2.02–3.17 units. Higher lime rates of 6.85–8.22 t·ha−1 increased soil pH sharply from 5.22 to 5.99 and 6.46, respectively, but such a rise in soil pH was not proportionally reflected in the yield increment. Higher available phosphorus contents of 7.16 and 6.01 mg·kg−1 were measured at the liming rates of 4.11 and 5.48 t·ha−1, respectively. Combined over the two years, 5.45 t·ha−1 lime application yielded the highest barley total biomass of 19,199 kg·ha−1 and a grain yield of 4,328 kg·ha−1, which are 46% and 30% higher than those of the control, respectively. It also yielded the highest marginal rate of return of 477% and a gross margin of 192,857.3 ETB1·ha−1, which is 53% higher than the control. Based on our results, 5.45 t·ha−1 of lime appears to have the optimal rate for economically viable barley production in the study area or similar environments.
