“…Plant root structure changes accordingly to maximize nutrient absorption (Giehl et al, 2014). L. perenne is drought-resistant and the root cluster can steadily extract certain nutrients from dry soil, which can survive for a long time even under extremely low water conditions (Safari et al, 2022). In this study, plant height of F. arundinacea and S. sudanense on loamy soil was significantly higher than that on sandy and clayey soil.…”

With the development of industrialization, soils around the world have been polluted by heavy metals and oil to different degrees in recent years, and soil remediation has become a global problem. Phytoremediation has a wide application prospect because of its environmental friendliness and easy availability of materials.ObjectiveTo explore the effects of soil types and root exudates on the removal of cadmium and petroleum hydrocarbon in soils.MethodA pot experiments with three soil types (sandy, loamy and clayey) of the Changning-Weiyuan area of Sichuan province and three root exudates (citric acid, glycine, and maltose) were carried out using Sorghum sudanense (Piper) Stapf., Lolium perenne L., and Festuca arundinacea L. as test materials. Plants were grown in soils contaminated by cadmium and petroleum at different concentrations.ResultThe biomass of S. sudanense, the translocation ratio and removal rate of cadmium in S. sudanense decreased gradually with increasing soil cadmium concentration. The promotion effects of the three root exudates on S. sudanense were in the following order: citric acid > glycine > maltose. At the same cadmium pollution conditions, the biomass levels of S. sudanense in sandy, loamy, and clayey soils were in the following order: clayey soil > loamy soil > sandy soil. On the contrary, the concentration, translocation ratio, and removal rate of cadmium in S. sudanense grown in the different soils treated with root exudates were in the following order: sandy soil > loamy soil > clayey soil. Under the three soil conditions, the fresh weight of F. arundinacea (0.36 ~ 0.68 g) and S. sudanense (0.51 ~ 0.99 g) increased significantly (p < 0.05). The total petroleum hydrocarbons degradation efficiencies of F. arundinacea, L. perenne, and S. sudanense were high in sandy soil (34.27% ~ 60.52%). Changing the type of root exudate had a significant impact on the degradation of total petroleum hydrocarbons in sandy soil (p < 0.05).ConclusionThis study showed that soil types impacted the accumulation of cadmium and petroleum in plants. Phytoremediation of cadmium and petroleum contaminated soil could be enhanced by the application of root exudates. This study recommend that the method is suitable for field remediation of soils contaminated with mild cadmium and petroleum hydrocarbons.

“…The positive effects of biochar on water retention in soil also extend to plant water status and proline levels under drought stress conditions Akhtar et al (2014) reported that increased water holding capacity (WHC) in soil due to biochar application enhanced leaf relative water content (RWC) in tomatoes subjected to deficit irrigation. Moreover, the application of biochar led to a reduction in proline content in various plants, including Quercus castaneifolia seedlings (Zoghi et al, 2019), Rosmarinus officinalis (Kasmaei et al, 2019), and perennial ryegrass (Lolium perenne L.) (Safari et al, 2023).…”

IntroductionAddressing the global demand for rice production necessitates innovative approaches to enhance upland rice yield in rainfed agroecosystems, considering the challenges posed by increasing population, limited land fertility, low productivity, and water availability.MethodsIn this study, our study investigated the impact of biochar and organic fertilizer on ten promising rice lines (G1 – G10) and two control (G11 – G12) cultivars under rainfed conditions. The experimental design used a split-plot design with four soil amendments as main plots, namely control, organic fertilizer, biochar, and biochar + organic fertilizer and 12 rice genotypes as subplot.ResultsThe absolute attainable yield gaps, differentiating organic and control (GAP1), biochar + organic and control (GAP2), and biochar and control (GAP3), ranged from 1.5 to 3.7 or increased of 91–580%, 0.8 to 3.5 (72–560%), and 0.6 to 2.58 tons/ha (58–472%), respectively. Notably, G2 + organic exhibited the highest positive absolute yield gap, ranging from 1.1 to 5.38 tons/ha, based on the yield gap matrix. Furthermore, genotype main effect plus genotype-environment interaction (GGE) biplot analysis identified G2 as the most promising rice line, displaying superior yield performance for cultivation in biochar and organic amended soils.DiscussionThese findings provide valuable insights for farmers, governments, and stakeholders, offering a roadmap to optimize rainfed areas for rice production, serving as practical guidance to enhance overall rice productivity in rainfed agroecosystems.

“…Studies have consistently shown that biochar has a significant impact on enhancing plant growth, as it effectively modifies the physio-chemical properties of the substrates (Zhang et al 2021, Krzyszczak et al 2022. Furthermore, numerous reports have highlighted the positive outcomes resulting from biochar amendment in substrates at drought stress (Obadi et al 2023, Safari et al 2023. The soil water retention property plays a significant role in soil management in defining available water content (AWC) in the soil for plants.…”

Low water availability is a significant constraint on global crop production. Exploration is needed regarding plant responses to drought in interaction with biochar, encompassing optimised water use and carbon allocation strategies. The size of the biochar particles also plays an important role, especially in influencing the dynamics of water and plant growth. This study explored the potential impact of biochar treatment on radish growth and drought tolerance. Finer biochar particles lead to the most substantial available water content for plants, increasing at around 30%, while medium and larger fractions increase by about 22% and 16%, respectively, compared to control soil. The chlorophyll fluorescence technique showed improved water management of drought stress at larger fractions of biochar. Our research underscores the potential of biochar treatments for environmental stresses and water scarcity in modern agriculture.
