“…These indicators include different criteria that offer insights into the sustainability, efficiency, and environmental impacts of agricultural systems (Figure 8). Examples of micro-level indicators include measures of resource efficiency, such as the ratio of resource inputs to agricultural outputs, highlighting how efficiently the resources are utilized, such as fertilizers [69][70][71][72][73][74][75], water [76][77][78], and energy [11,17,20,28,38,48]. Additionally, the indicators related to waste reduction, such as tracking the volume of waste generated per unit of agricultural production and assessing the extent of waste recycling or repurposing, provide valuable information on circularity efforts [33,77,79].…”

This article examines how circularity can be measured and evaluated in the agricultural sector. Circularity represents a key approach for promoting sustainability in agriculture and for the efficient management of resources. Through a comprehensive review of the scientific literature and employing rigorous selection methods, we identify the relevant indicators and tools for assessing circularity in the agri-food chain. The initial bibliometric analysis was performed by using a Biblioshiny instrument from R package tool Bibliometrics. Additionally, this article analyzes the methodologies based on the indicators and metrics that can be applied to measure the restorative capacity and effectiveness of the agricultural system. Most current research follows the 3R principles of the circular economy and establishes an evaluation index system based on the regional characteristics. Methods such as the multi-criteria decision analysis, data envelopment analysis, and life cycle assessment are the most used to date. For the micro-level analysis, system dynamics, material flow analysis, and emergy analysis were the most suitable. Our results provide a clear perspective on the current state of the research in the field of measuring circularity in agriculture and lay the groundwork for the future development of effective strategies for implementing the circular economy in this crucial sector.

“…Straw covering can effectively reduce soil moisture evaporation and regulate soil temperature [18][19][20]. Microbial decomposition and rainwater leaching covered with straw can improve soil fertility [21] and physicochemical properties [22][23][24], can promote soil water fertilizer interaction, and are widely used in conservation tillage [25,26].…”

Allelopathic Effects of Corn Straw and Its Water Extracts on Four Weed Species and Foxtail Millet

Straw covering is a protective tillage measure in agricultural production, but there is relatively little research on the allelopathic effects of corn straw on weeds and foxtail millet. This experiment studied the allelopathic effects of corn straw on four weeds (Chenopodium album, Setaria viridis, Echinochloa crus-galli and Amaranthus retroflexus) in foxtail millet fields, and also measured the growth indicators of foxtail millet. The study consisted of Petri dish and field experiments. Five treatments were used in the Petri dish experiment: clear water as control (0 g/L, TCK) and four types of corn straw water extracts. They were, respectively, the stock solution (100 g/L, T1), 10 X dilution (10 g/L, T2), 50 X dilution (2 g/L, T3), and 100 X dilution (1 g/L, T4) of corn straw water extracts. Additionally, seven treatments were set up in the field experiment, consisting of three corn straw covering treatments, with covering amounts of 3000 (Z1), 6000 (Z2) and 12,000 kg/ha (Z3), and four control treatments—one treatment with no corn straw cover (CK) and three treatments involving the use of a black film to create the same shading area as the corn straw covered area, with black film coverage areas of 50% (PZ1), 70% (PZ2), and 100% (PZ3), respectively. The results showed that the corn straw water extract reduced the germination rate of the seeds of the four weeds. The T1 treatment resulted in the allelopathic promotion of C. album growth but the inhibition of S. viridis, E. crus-galli, and A. retroflexus growth. Treatments T2, T3, and T4 all induced the allelopathic promotion of the growth of the four weeds. The order of the effects of the corn straw water extracts on the comprehensive allelopathy index of the four weed seeds was as follows: C. album > S. viridis > A. retroflexus > E. crus-galli. With an increase in the corn straw mulching amount, the density and total coverage of the four weeds showed a gradual downward trend, whereas the plant control effect and fresh weight control effect showed a gradual upward trend. All indices showed the best results under 12,000 kg/ha of mulching and returning to the field. Overall, corn straw coverage significantly impacted the net photosynthetic rate and transpiration rate of foxtail millet and increased the yield of foxtail millet. Under coverages of 6000 and 12,000 kg/ha, the growth of foxtail millet is better. Based on our findings, we recommend a corn straw coverage of 12,000 kg/ha for the allelopathic control of weeds in foxtail millet fields.

Film-stalk spaced dual mulching is a new type of cultivation measure that is increasingly highlighted in semi-arid areas in China. Despite its potential, there is limited understanding of how different mulching materials affect both soil quality and crop yield in these areas. To address this gap, we conducted a two-year (2020–2021) field experiment in central China to explore the yield-enhancing mechanisms and assess the impact of various mulching materials on soil and corn yield. The experiment comprised six treatments, i.e., plastic film-whole stalk spaced mulching in fall (PSF), plastic film-whole stalk spaced mulching in spring (PSS), black and silver plastic film-whole stalk spaced mulching in spring (BPSS), biodegradable film-whole stalk spaced mulching in spring (BSS), liquid film-whole stalk spaced mulching in spring (LSS), and non-mulching cultivation (CK). Results revealed that BPSS demonstrated the most significant yield increase, surpassing CK by a notable 10.0% and other mulching treatments by 2.4%–5.9%. The efficacy of BPSS lied in its provision of favorable hydrothermal conditions for corn cultivation, particularly during hot season. Its cooling effect facilitated the establishment of optimal temperature conditions relative to transparent mulching, leading to higher root growth indices (e.g., length and surface area), as well as higher leaf photosynthetic rate and dry matter accumulation per plant. Additionally, BPSS maintained higher average soil moisture content within 0–100 cm depth compared with biodegradable mulching and liquid mulching. As a result, BPSS increased activities of urease, catalase, and alkaline phosphatase, as well as the diversity and abundance of soil bacteria and fungi in the rhizosphere zone of corn, facilitating nutrient accessibility by the plant. These findings suggest that selecting appropriate mulching materials is crucial for optimizing corn production in drought-prone areas, highlighting the potential of BPSS cultivation.
