“…Conserving soil moisture is important in controlling various atmospheric, ecological, hydrological, and pedological processes, particularly in water-limited environments [55]. In addition, onsite moisture storage favors the survival of trees and rehabilitation of degraded land which results through proper implementation of SWC [62].…”

“…For instance, Yazie, et al [44] reported that gully density was higher in cultivated areas at gentle slope gradients due to poor tillage systems and lack of appropriate land management measures in the Upper Blue Nile basin. Thus implementing PSWC practices are increasing food production without further depleting soil and water resources, adding high amounts of biomass to the soil, causing minimal soil disturbance, restoring soil fertility, and increasing the resilience of farming systems to climatic risk [18,20,54,55].…”

Land degradation in the form of soil erosion and nutrient depletion threatens food security and the sustainability of agricultural production in Sub-Saharan Africa [1]. For instance, soil erosion is the main environmental and economic problem in the highland of Ethiopia [2][3][4]. Soil erosion induced by water had an impact on national food supply [5], deteriorate soil fertility and reduce agricultural productivity [6,7], downstream flooding and reservoir sedimentation [8,9] and loss of valuable plant nutrients [10]. In order to solve soil degradation problems, in Ethiopia efforts towards soil and water conservation (SWC) goals were started in the mid-1970s and 80s to alleviate soil erosion and low crop productivity [11,12]. Combating land degradation and investing in the

“…The soil temperature and moisture content mainly depend on the climate characteristics and soil conditions of the planting area [3] . Air temperature, solar radiation, atmospheric circulation and precipitation determine the environmental conditions of the soil [4] . Soil compactness and soil porosity determine the exchange rate of water and heat between soil and the environment [5] .…”

In cold and arid regions, soil moisture content and accumulated temperature were seriously insufficient during spring sowing, which made it difficult for soybean seedling to emerge. Based on the principle of earthworm optimization and improvement of soil structure, this study innovatively designed a biomimetic earthworm dynamic soil looser through bionic design and theoretical calculation. By highly reducing the movement path and mode of earthworm in the soil, the mechanism could improve the soil temperature (ST) and soil moisture content (SMC), and thus greatly improve the soybean emergence rate (SER). In this study, the effects of biomimetic earthworm dynamic soil looser and its design parameters on soil temperature (ST), soil moisture content (SMC) and soybean emergence rate (SER) were investigated by two-factor test, analysis of variance (ANOVA) and Least significant Difference (LSD). Regression analysis was used to establish the mathematical model between design parameters and soybean emergence rate. MATLAB software was used to optimize the model, and the optimal design parameter combination was obtained. The contrast experiments showed that the biomimetic earthworm dynamic soil looser could construct the soil structure more suitable for the cold and arid regions. Compared with rotary blade (RB) and notched disc harrow (DH), biomimetic earthworm dynamic soil looser could increase soil moisture content by 41.30% and 27.50%, respectively. Compared with the notched disc harrow, the soil temperature could be increased by 7.97%. There was no significant difference between the effect of rotary blade on soil temperature (p>0.05). The soybean emergence rate was increased by 25.40% and 20.70%, respectively, compared with that of notched disc harrow and rotary blade.
