“…A similar result was reported by (Bekele et al, 2018) that integrated application of VC alone or in combination with the P fertilizer increased the exchangeable Na + of soil. This is also supported by the report of (Alamayo, Amsalu, & Zerihun, 2022;Ayeni & Adetunji, 2010), who indicated that exchangeable soil bases increased when the bio fertilizer was applied alone or in combination with the lime and P fertilizer. Therefore, the increase in soil Na + could be due to added Na from VC (Bekele et al, 2018).…”

Purpose Soil degradation and nutrient depletion have gradually increased and become serious threats to agricultural productivity in Ethiopia. This research aims to assess the effects of selected integrated soil fertility management (ISFM) practices on soil properties in Dire and Legedadi watersheds, central highlands of Ethiopia. Knowing how ISFM practices affect soil quality indicators will enable us to take the appropriate measure to improve sustainable crop yield while reducing the ongoing soil degradation. Methods A field experiment of eight treatments under a randomized complete block design with three replications was conducted in the 2021 and 2022 cropping seasons. Selected soil physicochemical properties were determined following the standard protocols. Soil organic carbon (SOC) stock, Nitrogen (N) stock and carbon sequestration (t ha− 1) were calculated according to Donvan’s equation. Results Analysis of variance showed that soil samples collected from each plot indicated significant differences in soil organic carbon, total Nitrogen (TN), available phosphorus (Pav), exchangeable bases (Ca2+, Na+, and Kexc) and Cation exchange capacity (CEC). Soil pH and moisture showed improvement compared to the pre-planting soil sample. Combined application of vermicompost (VC), NPS + Urea fertilizers significantly (p < 0.05) increased SOC, Pav, Kexc, Na+, and CEC. The highest TN content (0.36% and 0.30%) in Dire and Legedadi sites, respectively, water holding capacity and soil carbon stock were obtained in 100% VC rate added treatment. Similarly, the wheat-faba bean intercropped plot showed a significant (p < 0.05) effect on soil carbon stock and sequestration over the control in both study sites. Conclusions Integrated application of VC and NPS + urea fertilizers improved soil quality. From results of the current experiment for two years, it can be concluded that integrated application of 50% VC with 50% NPS + urea fertilizer improved most physicochemical properties soil of Luvisol and Vertisol in Dire and Legedadi sites, respectively. This implies that the combined application of VC and NPS + urea fertilizers helps farmers to reduce the use of inorganic fertilizer requirement by 50%.

The adoption of integrated soil fertility management (ISFM) practices can improve soil quality and sustainably increase crop yield while slowing down the rate of ongoing degradation. This research assessed the effects of selected ISFM practices on soil properties at the Dire and Legedadi watersheds, central highlands of Ethiopia, in the 2021 and 2022 cropping seasons. Eight treatments were selected (sole wheat, sole faba bean, 100% recommended NPS + urea fertilizers, 100% recommended vermicompost (VC), wheat with half dose both NPS + urea and VC, wheat and faba bean intercropping with half dose both NPS + urea and VC, wheat and faba bean intercropping with half‐dose NPS + urea fertilizers, and wheat and faba bean intercropping with 50% VC). The treatments were studied on farmers’ fields using a randomized complete block design with three replications. Analysis of variance showed that soil samples collected from each plot indicated significant differences in soil organic carbon (SOC), total nitrogen (TN), available phosphorus (Pav), exchangeable bases (Ca2+, Na+, and Kexc), and cation exchange capacity (CEC). Soil pH and moisture showed improvement in combined fertilizers application compared to the preplanting soil sample. A combined application of VC and NPS + urea fertilizers significantly (p < 0.05) increased SOC, Pav, K+, Na+, and CEC compared to the control. A combined application of VC and NPS + urea fertilizers improved the soil quality. The highest TN contents of 0.36% at the Dire site and 0.30% at the Legedadi site were obtained with the full dose VC treatment. Additionally, this treatment resulted in the greatest water‐holding capacity and soil carbon stock at both sites. Similarly, the wheat‐faba bean intercropped plots showed a significant (p < 0.05) effect on the soil carbon stock and sequestration over the control in both study sites. Based on the results of the current study, it can be concluded that the combined application of a half dose of each VC and NPS + urea fertilizers improved most soil physicochemical properties at both sites. This suggests that using a combination of VC and NPS + urea fertilizers can help farmers reduce their inorganic fertilizer needs by 50%.
