“…Nevertheless, large-sized plants are certainly not a panacea for all conditions. Studies have indicated that the removal rate of P by slender Schoenoplectus nearly doubled that of large-shaped Phragmites, especially in winter (López et al, 2016;Carrillo et al, 2022). C. indica was better than P. purpureum at TN removal in summer but the opposite was true in winter (Yang et al, 2007).…”

“…Diverse growth rhythms could also extend the period for nutrient uptake across seasons with efficient nutrient retention (Manolaki et al, 2020). To date, most planted CWs are monoculture or with a low plant richness, and only a handful of researches employed polyculture, which has drawn contradictory conclusions (Aguinaga et al, 2018;Fahim et al, 2021;Carrillo et al, 2022). Very few studies have considered polyculture with various growth forms, in order to increase the functional diversity of plants and the nutrition turnover rate of CWs (Calheiros et al, 2015).…”

IntroductionPlant richness is thought to improve the function of constructed wetlands (CWs), but most CWs are planted with monocultures, with only a few employed polycultures, which have drawn contradictory conclusions. We suppose functional diversity is the key to better performance of plant communities and hypothesize that CWs planted with diverse growth forms are superior in plant growth and nutrient removal.MethodsIn this study, six emergent plant species categorized into slender type (Schoenoplectus tabernaemontani, Typha orientalis), fan type (Iris sibirica, Acorus calamus) and large type (Canna indica and Thalia dealbata) were planted in monocultures, combinations (two species of the same growth form) and mixed polycultures (six species of three growth forms). We then compared how plant growth and nutrient uptake differed among treatments.ResultsIt showed that the polyculture considerably increased the removal of total nitrogen (TN) and total phosphorus (TP), but the combination did not outperform monoculture. High consistency in the patterns between underground biomass and total biomass indicated that plant roots were essential for nutrient consumption. Compared with slender and fan plants, the large plants had a greater biomass increase in polycultures, which greatly accelerated the absorption and assimilation of TN and TP.ConclusionOur study indicated that plant community with various growth forms reduced the intensity of interspecific competition, increased the functional diversity, and greatly enhanced the ability of pollutant removal. Our results also provide some suggestions for plant selection and combination designs in CWs.

“…According to the results, it is important to highlight that the plant or culture of species is a vital factor to consider for the best design and environmental performance of CWs [4,44]. The choice of vegetation-composing CWs should not be based only on the plant removal capacity (Table 1) since the introduction of invasive plants can be an ecological problem [45].…”

The assessment of constructed wetlands (CWs) has gained interest in the last 20 years for wastewater treatment in Latin American regions. However, the effects of culture systems with different ornamental species in CWs for phytoremediation are little known. In this study, some chemical parameters such as total suspended solids (TSS), chemical oxygen demand (COD), phosphate (PO4-P), and ammonium (NH4-N) were analyzed in order to prove the removal of pollutants by phytoremediation in CWs. The environmental impact index based on eutrophication reduction (EI-E) was also calculated to estimate the cause-effect relationship using CWs in different culture conditions. C. hybrids and Dieffenbachia seguine were used in monoculture and polyculture (both species mixed) mesocosm CWs. One hundred eighty days of the study showed that CWs with plants in monoculture/polyculture conditions removed significant amounts of organic matter (TSS and COD) (p > 0.05; 40–55% TSS and 80–90% COD). Nitrogen and phosphorous compounds were significantly lower in the monoculture of D. seguine (p < 0.05) than in monocultures of C. hybrids, and polyculture systems. EI-E indicator was inversely proportional to the phosphorous removed, showing a smaller environmental impact with the polyculture systems (0.006 kg PO₄3− eq removed) than monocultures, identifying the influence of polyculture systems on the potential environmental impacts compared with the phytoremediation function in monocultures (0.011–0.014 kg PO₄3− eq removed). Future research is required to determine other types of categories of environmental impact index and compare them with other wastewater treatment systems and plants. Phytoremediation with the ornamental plants studied in CWs is a good option for wastewater treatment using a plant-based cleanup technology.

“…The common cropping pattern used by farmers in the Ngablak and Getasan sub-subdistricts is the monoculture and polyculture. The monoculture is a cropping pattern using one type of plant in one cropping period, while the polyculture is a cropping pattern that use more than one type of plant in one cropping period.In the polyculture cropping pattern interaction and competition of plant is different than monoculture cropping patern [1]. Variations in surface plant species will provide the potential for a diversity of available biomass to be returned to the soil, which will later become a nutrient contributor after the decomposition process [10].…”

“…Variations in surface plant species will provide the potential for a diversity of available biomass to be returned to the soil, which will later become a nutrient contributor after the decomposition process [10]. In addition, the pattern of monoculture and polyculture plant species also affects the number of communities and types of microbes in the land that are useful in nutrient cycling [1]. The implications cropping pattern for soil properties must be considered by farmers.…”

Element P in Andisol soil is absorbed by amorphous minerals such as allophane, imogolite , and amorphous Al/Fe. This study aims to determine the retention and availability of P as well as differences in soil chemical properties on land with monoculture and polyculture cropping patterns. Parameters measured were available-P, P-retention, texture, CEC, Corganic , pH (H2O, KCl , NaF ), Potential-P, Al/Fe/Si with three selective solvents. The sample used 3 replicates at 2 depths (0-20cm and 20-40cm) and 2 different locations, namely Ngablak Subdistrict and Getasan Subdistrict. The data obtained were processed using ANOVA for the RCBD design and LSD Fisher’s follow-up test. P retention data in Ngablak Subdistrict showed significantly different results, while those in Getasan Subdistrict were not significantly different. Available P did not show any significant difference, but the availability of P was higher in polyculture land. On agricultural land in Ngablak Subdistrict, cropping patterns have a significantly different effect on soil properties in the form of P retention and C-Organic. Meanwhile, on agricultural land in Getasan Subdistrict, cropping patterns had significantly different effects on soil properties of pH H2O, pH KCl , Potential-P, amorphous Al + Fe , and Allophane + Imogolite.
