“…A growing body of literature has demonstrated the importance of proper soil management/mulching for minimizing soil erosion by water [98][99][100][101][102][103][104][105]. Rahma et al [106] illustrated that soil mulching is an effective way of conserving water and soil in the Loess Plateau (China) because of reduction of surface runoff as well as protecting soil aggregates from the direct impact of raindrops. Similarly, Keesstra et al [93] demonstrated that runoff can be reduced from 65.6% to 50.7% by using straw mulching in citrus orchards.…”

The Mediterranean part of Syria is affected by soil water erosion due to poor land management. Within this context, the main aim of this research was to track soil erosion and runoff after each rainy storm between September 2013 and April 2014 (rainy season), on two slopes with different gradients (4.7%; 10.3%), under three soil cover types (SCTs): bare soil (BS), metal sieve cover (MC), and strip cropping (SC), in Central Syria. Two statistical multivariate models, the general linear model (GLM), and the random forest regression (RFR) were applied to reveal the importance of SCTs. Our results reveal that higher erosion rate, as well as runoff, were recorded in BS followed by MC, and SC. Accordingly, soil cover had a significant effect (p < 0.001) on soil erosion, and no significant difference was detected between MC and SC. Different combinations of slopes and soil cover had no effect on erosion, at least in this experiment. RFR performed better than GLM in predictions. GLM’s median of mean absolute error was 21% worse than RFR. Nonetheless, 25 repetitions of 2-fold cross-validation ensured the highest available prediction accuracy for RFR. In conclusion, we revealed that runoff, rain intensity and soil cover were the most important factors in erosion.

“…Land degradation remains a critical global concern, especially in India, where nearly 44% of total land has been degraded (Bhattacharyya et al, 2015; Moraes De Sa et al, 2013; Mythili & Goedecke, 2016). The use of crop residues increases soil organic matter (OM), conserves soil water (Rahma, Warrington, & Lei, 2019), promotes biological activity (Huang, Xu, & Chen, 2008), promotes soil aggregation, strengthens nutrient cycling (Chen & Xu, 2005), reduces abrupt fluctuations in soil temperature, and improves soil tilth (Wilhelm, Johnson, Karlen, & Lightle, 2007) and thus reduces land degradation (Aulakh & Sidhu, 2015; Jat et al, 2018). Crop residues also enhance soil quality by reducing soil erosion and buffering against the effects of pollution (Mickelson, Boyd, Baker, & Ahmed, 2001).…”

“…Singh and Sidhu (2014) and Yadav, Shivay, Singh, Bhatia, & Sharma (2017) estimated that 1 t of wheat residue can recycle about 455 kg C, 5.0-6.0 kg N, 1.0 kg P, and 15.0-17.0 kg K in the soil. The amount of wheat residue applied directly affected the rate of soil loss (Rahma et al, 2019). Appropriate application rate remains a crucial factor that greatly influences the effectiveness of crop residues in reducing soil degradation (Jordán, Zavala, & Gil, 2010).…”

Sustaining the properties of black soil in Central India through crop residue management in a conservation‐agriculture‐based soybean–wheat system

Soybean–wheat cropping system is the most commonly used in the black soil of India which produces enormous amounts of nutrient‐rich residues. However, black soil has some production limitations, such as rapid drying, high bulk density, low nutrients, and poor microbial populations, making it vulnerable to degradation. Optimal retention of soybean and wheat residues in black soil under the zero‐tillage (no‐till) system can improve soil properties and help protect the land from degradation. Thus, the main objective of this study was to test the effect of different levels of soybean and wheat residue retention on the physical, chemical, and biological properties of black soil. Therefore, an experiment was conducted in the zero‐tillagesoybean–wheat system at the Indian Institute of Soil Science, Bhopal, India from 2014 to 2018. In this study, the effect of four levels of soybean and wheat residue retention (no residue, 30, 60, and 90%) on soil properties was evaluated. Results revealed that soil organic carbon (C) significantly increased from 0.67 to 1.0% in 5 years through 90% residue retention. Retaining 90% (7.0 t) of soybean residue added 2.9 t C, 197.3 kg nitrogen (N), 32.4 kg phosphorus (P), and 89.7 kg potassium (K) in 5 years, while 6.2 t C, 85.7 kg N, 15.3 kg P, and 232.2 kg K were added through 90% (13.8 t) wheat residue during the same period. Different pools of soil C (oxidizable, labile, and particulate organic matter (OM)‐carbon), soil OM, soil moisture, soil porosity, available nutrients, and bacterial, fungal, and actinomycetes count was significantly enhanced due to retention of 90% residue over 60 and 30%. It was observed that retention of 90% soybean and wheat residues (7.0 and 13.8 t ha−1, respectively) significantly improved the physical, chemical, and biological properties of black soil in 5 years, therefore protected the soil from degradation.

“…Consistent with our study, Jourgholami and Etehadi Abari (2017) found that applying straw and sawdust cover to a skid trail reduced runoff by 36.5 and 72.8% and the sediment yield by 51.9 and 94.9%, respectively, relative to the control slopes. Similarly, Rahma et al (2019) concluded that slopes treated with wheat straw mulch reduced erosion compared to bare slopes.…”

Simulated rainfall experiments were performed on bare, undecomposed litter layer and semi-decomposed litter layer slopes with litter biomasses of 0, 50, 100 and 150 g m À2 , respectively, to evaluate the effect of the undecomposed layer and semidecomposed layer of Quercus variabilis litter on the soil erosion process and the particle size distribution of eroded sediment. The undecomposed layer and semidecomposed layer of litter reduced the runoff rate by 10.91-27.04% and 12.91-36.05%, respectively, and the erosion rate by 13.35-40.98% and 17.16-59.46%, respectively. The percentage of smaller particles (clay and fine silt particles) decreased and the percentage of larger particles (coarse silt and sand particles) increased with an increased rainfall duration on all treated slopes, while the extent of the eroded sediment particle content varied among the treated slopes with the rainfall duration, with bare slopes exhibiting the largest variability, followed by undecomposed litter layer slopes and finally semi-decomposed litter layer slopes. The clay and sand particles were transported as aggregates, and fine silt and coarse silt particles were transported as primary particles. Compared with the original soil, sediment eroded from all treated slopes was mainly enriched in smaller particles. Furthermore, the loss of the smaller particles from the undecomposed litter layer slopes was lower than that from the semi-decomposed litter layer slopes, indicating that the undecomposed litter layer alleviated soil coarsening to some extent. The findings from this study improve our understanding of how litter regulates slope erosion and provide a reference for effectively controlling soil erosion.
