Abstract
Abstract Co-planting two or more species on the same piece of land, with overlapping time or not, has been suggested to increase both crop production and long-term sustainability. On soils that are slightly or moderately contaminated with heavy metals, hyperaccumulators have been co-planted with crops to clean the soil and produce safe agricultural products. Despite the increasing number of greenhouse experiments and field trials that investigate the co-planting mechanisms and efficiency, the consistency, stability, and applicability of this technology and its contribution to sustainability remain unclear. From published literature, we collected 118 co-planting combinations involving hyperaccumulators, and compared them with their monoculture controls. Co-planting averagely decreased the shoot arsenic concentration by ∼23.4% and cadmium by ∼13.4%. Co-planting controls the crop contamination as long as the hyperaccumulator and crop species are correctly selected, and the soil heavy metal is within the safe range. Further, a sustainability assessment criterion for the utilization of contaminated agricultural soil was proposed, taking As-contaminated soil as an example. A decision framework and a guideline for co-planting were established to aid in the decision-making. The outlook of co-planting as a sustainable solution and the future development were prospected.

期刊介绍:
Two of the most pressing global challenges of our era involve understanding and addressing the multitude of environmental problems we face. In order to tackle them effectively, it is essential to devise logical strategies and methods for their control. Critical Reviews in Environmental Science and Technology serves as a valuable international platform for the comprehensive assessment of current knowledge across a wide range of environmental science topics.
Environmental science is a field that encompasses the intricate and fluid interactions between various scientific disciplines. These include earth and agricultural sciences, chemistry, biology, medicine, and engineering. Furthermore, new disciplines such as environmental toxicology and risk assessment have emerged in response to the increasing complexity of environmental challenges.
The purpose of Critical Reviews in Environmental Science and Technology is to provide a space for critical analysis and evaluation of existing knowledge in environmental science. By doing so, it encourages the advancement of our understanding and the development of effective solutions. This journal plays a crucial role in fostering international cooperation and collaboration in addressing the pressing environmental issues of our time.
