“…These advantages may promote major elevation in the biomass of the radicular system and of the aerial parts of the plant (Luo et al, 2015) (Figure 2). In addition to the water conservation of the soil and the modification of the temperature, mulch promote improvements in the physical, chemical and biological aspects of the soil, preventing erosion, diminishing the impacts from the drops of rainfall, improving the structure, porosity and aeration, also providing nutrients to the plants after the mineralization process of the organic matter and stimulating the activity of the beneficial microbial fauna in the soil (Yang et al, 2018b;Namaghi et al, 2018;Chen et al, 2018).…”

The Brazilian semi-arid is an area that has a strong influence on climatic factors and agricultural vulnerability, which govern the availability and supply of fodder. The understanding of the limitations and the alternatives to be adopted, aid in the improvement of the systems of production of fodder and an increase in the benefits of the system. In this review, we sought to address agrometeorological aspects and agronomic techniques aimed at improving resilience in forage cactus production systems under different cropping systems in arid and semi-arid environments through information on the stability of the plant population contributing to reducing the risk environmental degradation and production losses.

“…Chen et al (2018) noted that, in restored mangrove forests, SOC relies on mangrove organic matter, using the δ 13 C values [30]. Chen et al (2018) also reported that maize mulch increases SOC by 22% in topsoil [31]. Likewise, LIC and PIC are distinguished by δ 13 C, which is 0% for LIC, while for PIC it is related to the δ 13 C of SOC [17,32].…”

Soil organic carbon (SOC) and soil inorganic carbon (SIC) play essential roles in carbon cycling in terrestrial ecosystems; however, the effects of crop cultivation on them are still poorly understood, especially in alkali sodic soils widely distributed in semiarid regions. Alkali sodic soils from cornfields and paddies with cultivation years of 5, 15, and 25 were analyzed here to assess the response of soil properties and soil carbon pools to crop cultivation. Soil pH and exchangeable sodium percentages decrease in accordance with cultivation years, while enzyme activity (amylase, invertase, and catalase) shows a contrary trend. Soil pH and exchangeable sodium percentages are negatively correlated with SOC, but positively correlated with SIC. Redundancy analysis reveals an obvious relationship between SOC and invertase activity. The percentage of δ 13 C SOC found here is approximately -24.78% to -22.97% for cornfields and approximately -26.54% to -23.81% for paddies, suggesting that crop cultivation contributes to SOC sequestration and stocking, increasing with cultivation years. The percentage of δ 13 C SIC found here is approximately 1.90% to 3.73% , proving that lithogenic inorganic carbon is the major SIC, where the stock decreases with increasing cultivation years. Significant total carbon stock loss is observed in cornfields, while it is preserved at 120 Mg ha −1 in paddies. We conclude here from the results that corn and rice cultivation reduce alkali sodic conditions in soil, thereby improving soil enzymes and favoring SOC stocking, but reducing SIC stocks.

“…Long‐term cropping studies under no‐till have resulted in increased SOC and total N with increased crop rotation diversity (Alhameid, Ibrahim, Kumar, Sexton, & Schumacher, 2017; Maiga et al., 2019). Cropping systems that incorporate legumes under no‐till have also resulted in increased SOC (Conceição, Dieckow, & Bayer, 2013; Hobley et al., 2018), but other studies suggest that incorporating legumes causes a rhizosphere priming effect that reduces the benefit of residue retention on SOC (Chen et al., 2018).…”

Understanding the impacts of long‐term fertilizer management and rotation diversity on soil C and N is needed under a changing climate. The objective of this study was to evaluate the effects of N fertilizer level and crop rotation diversity on soil organic carbon (SOC) and soil N stocks from a 34‐yr study located in eastern Nebraska. Seven crop rotations (three continuous cropping systems; two 2‐yr crop rotations; and two 4‐yr crop rotations) and three N levels were compared. Soil samples were taken to a depth of 150 cm. Differences in SOC stocks were largely confined to the 0‐ to 7.5‐cm depth, with greater SOC (P = .0002) in rotations than continuous cropping systems and greater SOC (P = .0004) in 4‐yr vs. 2‐yr rotations. Total soil N was greater with increased crop rotation diversity for the 0‐ to 30‐cm soil profile. Greater SOC levels occurred with N fertilization for the 0‐ to 7.5‐cm depth. At the 0‐ to 150‐cm soil depth, SOC stocks were similar between N levels and greater for the 4‐yr vs. 2‐yr crop rotations (P = .0492). Trends in total N stocks were similar to those of SOC stocks. Overall, crop rotation had a larger effect on SOC and N stocks than N fertilizer.
