“…Adomako et al reported that in Cd polluted water Pistia stratiotes produced 70% - 100% more biomass when a higher level of nutrient was provided [ 6 ]. In another study, regardless of the addition of nitrogen and phosphorus fertilizer alone or combined nitrogen and phosphorus fertilization, the biomass of plants under heavy metal (Cd, Cu and Pb) treatment was increased [ 28 , 49 ]. The reason for the positive effect of high nutrient availability is perhaps that it can dilute Cd concentration in plants and mitigate the toxicity of Cd to plants by promoting plant growth and reducing uptake and accumulation of Cd in plants [ 50 – 54 ].…”

“…Overall, increased nutrients and high light can alleviate adverse effects of Cd stress on growth of H . vulgaris and may improve the adaptability and tolerance of plants to Cd exposure [ 49 ]. Therefore, one potential application is that sufficient nutrients and light can increase the efficiency of plants to restore the polluted wetland by accumulating heavy metals [ 6 , 23 ].…”

Heavy metal pollution is becoming a serious problem in wetland and often co-occurs with nutrient availability and light conditions variation. We hypothesized that nutrient availability and light condition can affect the growth of wetland plants under heavy metal stress. To test this hypothesis, single ramets of a common, clonal wetland plant Hydrocotyle vulgaris were grown for four weeks at three levels of cadmium with three levels of nutrient availability under 30% or 100% light conditions. High level of nutrient availability and high light condition overall promoted growth of H. vulgaris under Cd stress. Under the two light conditions, responses of H. vulgaris to Cd treatments differed among three nutrient levels. Under 30% light condition, 2 mg L-1 Cd2+ treatment decreased total mass at the low nutrient level and decreased ramet number at the medium nutrient level; 0.5 and 2 mg L-1 Cd2+ treatments decreased leaf mass ratio at the low and the medium nutrient levels. Under 100% light condition, 2 mg L-1 Cd2+ treatments significantly decreased total mass at the high level of nutrients; 2 mg L-1 Cd2+ treatment decreased ramet number at the medium and the high nutrient levels and decreased leaf mass ratio at the medium nutrient levels. Our results suggested that Cd stress can interact with nutrient availability and light condition to affect the performance of wetland plants such as H. vulgaris.

“…Nitrogen, accounting for approximately 60% of the total annual chemical fertilizer applications, is essential for plant growth and development. In agriculture, large-scale and heavy nitrogen fertilizer application is a common approach to increase crop yield, while it can also increase disease occurrence . Therefore, enhancing both NUE and disease resistance is crucial to ensuring high crop yields.…”

“…In agriculture, large-scale and heavy nitrogen fertilizer application is a common approach to increase crop yield, while it can also increase disease occurrence. 36 Therefore, enhancing both NUE and disease resistance is crucial to ensuring high crop yields. In the early 1970s, the acid growth theory was proposed, recognized as a physiological mechanism explaining cell expansion.…”

Soil remediation with minimum amendments is a good strategy for tailings disposal. Carbonate‐rich gold‐copper mine tailings occurring alongside the Yangzi River, China, were employed as the objective in this study. They showed the characteristics of fine particles and alkaline pH with high density and low nutrition. The amendments including bacterial fertilizer (BF), polymer, peat, straw, and compound fertilizer (CF) were used for soilless remediation on the tailings. Soil quality index (SQI) involved in tailing properties and growth characteristics of ryegrass was used to optimize the combination of amendments. The results showed that the optimum amendment combination was 0.2% BF + 0.6% CF + 0.2% polymer + 10% peat and 2% straw. Tailing nutrients such as soil organic matter (5.56%), available nitrogen (93.6 mg kg−1), available phosphorus (51.7 mg kg−1), available potassium (711 mg kg−1), and ryegrass exhibited the highest germination rate and biomass level under the optimal improvement conditions. Additional environmental assessments revealed that soilless treatment of the tailings helped to convert Cu, Zn, and As into residual forms. These findings show a good strategy for tailings soil improvement and provide a promising perspective of the soilless remediation for fine carbonate‐rich metal tailings.
