“…The supplementation of biochar, especially SBC, ameliorated the As-induced phytotoxicity in quinoa both under normal and saline soil environments. Previous studies have also reported the efficacy of biochar for reducing the phytotoxicity induced by As (Shabbir et al, 2021;Abbas et al, 2022;Naeem et al, 2022 and the references therein). Improved plant growth with biochar application can be attributed to the increased cationic exchange capacity (CEC) and pH of the soil, improved nutritional status and water holding capacity of the soil, and FIGURE E ect of salinity, arsenic, and their combination on the activities of SOD (A), CAT (B), and POD (C) of quinoa supplemented with no biochar (NBC), biochar (BC), and silicon-nanoparticles doped biochar (SBC).…”

“…The adverse effects of soil salinity on plants are mainly manifested as osmotic stress, ion toxicity, and nutritional imbalances. These disorders may trigger secondary metabolic changes, i.e., reduction in cell division, photosynthetic pigments, and oxidative damage leading to complete destruction of crops (Flowers and Colmer, 2015 ; Abbas et al, 2022 ). The damage caused to the plants by excessive salt concentration is dependent on exposure time, plant genotype, growth stage, and soil type (Abbas et al, 2021 ; Shabbir et al, 2021 ).…”

“…To deal with the problem of food security on saline soils, the cultivation of salt-tolerant crops such as quinoa could be one of the plausible options (Abbas et al, 2022 ). Quinoa is a facultative halophyte naturally equipped with the potential to grow on saline soils contaminated with heavy metals (Shabbir et al, 2021 ; Naheed et al, 2022 ), and produce seeds of exceptional nutritional quality providing countless medicinal benefits (Gaikwad et al, 2021 ).…”

The increasing contamination of soil with arsenic (As), and salinity has become a menace to food security and human health. The current study investigates the comparative efficacy of plain biochar (BC), and silicon-nanoparticles doped biochar (SBC) for ameliorating the As and salinity-induced phytotoxicity in quinoa (Chenopodium quinoa Willd.) and associated human health risks. Quinoa was grown on normal and saline soils (ECe 12.4 dS m−1) contaminated with As (0, 20 mg kg−1) and supplemented with 1% of BC or SBC. The results demonstrated that plant growth, grain yield, chlorophyll contents, and stomatal conductance of quinoa were decreased by 62, 44, 48, and 66%, respectively under the blended stress of As and salinity as compared to control. Contrary to this, the addition of BC to As-contaminated saline soil caused a 31 and 25% increase in plant biomass and grain yield. However, these attributes were increased by 45 and 38% with the addition of SBC. The H2O2 and TBARS contents were enhanced by 5 and 10-fold, respectively under the combined stress of As and salinity. The SBC proved to be more efficient than BC in decreasing oxidative stress through overexpressing of antioxidant enzymes. The activities of superoxide dismutase, peroxidase, and catalase were enhanced by 5.4, 4.6, and 11-fold with the addition of SBC in As-contaminated saline soil. Contamination of grains by As revealed both the non-carcinogenic and carcinogenic risks to human health, however, these effects were minimized with the addition of SBC. As accumulation in grains was decreased by 65-fold and 25-fold, respectively for BC and SBC in addition to As-contaminated saline soil. The addition of SBC to saline soils contaminated with As for quinoa cultivation is an effective approach for decreasing the food chain contamination and improving food security. However, more research is warranted for the field evaluation of the effectiveness of SBC in abating As uptake in other food crops cultivated on As polluted normal and salt-affected soils.

BackgroundSoil salinity and heat stress are serious threats to crop production around the globe due to climate change. Potassium (K) has well‐established role in plants under salinity stress; however, its effectiveness under the combined stress of salinity and heat is not well known.AimsThe current study was planned to explore the role of K on growth, physiological, and oxidative stress responses of two varieties of quinoa (Puno and Vikinga) exposed to salinity and heat stress.MethodsQuinoa plants were exposed to NaCl treatments (0, 200 mM). Additionally, plants were either kept under ambient temperature (32/12°C day/night) or 5°C high temperatures and supplemented with 0 and/or 10 mM K.ResultsThe combined stress of salinity and heat resulted in drastic decrease in plant growth (≈50% for Puno and 60% for Vikinga), pigment contents, and stomatal conductance of both varieties. Heat stress magnified the accumulation of sodium (Na) under salt stress that limited the uptake of K in both varieties. Under the combined treatment of salinity and heat, the contents of hydrogen peroxide (H2O2) were 8‐ and 9‐fold, and thiobarbituric acid reactive substances were 11‐ and 13‐fold higher in Puno and Vikinga, respectively. The K supplementation enhanced plant growth, stomatal conductance, pigments, and K contents and decreased the accumulation of Na in both varieties facing salt and heat stress. Additionally, K also helped the plants to overcome the oxidative stress and resulted in 17.5‐, 19‐, and 14‐fold higher activities of catalase, superoxide dismutase, and peroxidase in Puno and 14‐, 15‐, and 12‐fold higher activities of these enzymes in Vikinga.ConclusionsDue to better growth, ionic homeostasis, and higher activities of antioxidant enzymes, Puno is regarded as a more tolerant variety than Vikinga against the combined stress of salinity and heat. Moreover, the external supply of K is very promising for quinoa facing the dual stress of salinity and heat under the changing climatic conditions.

Biochar is colonized by select arbuscular mycorrhizal fungi in agricultural soils

Arbuscular mycorrhizal fungi (AMF) colonize biochar in soils, yet the processes governing their colonization and growth in biochar are not well characterized. Biochar amendment improves soil health by increasing soil carbon, decreasing bulk density, and improving soil water retention, all of which can increase yield and alleviate environmental stress on crops. Biochar is often applied with nutrient addition, impacting mycorrhizal communities. To understand how mycorrhizas explore soils containing biochar, we buried packets of non-activated biochar in root exclusion mesh bags in contrasting agricultural soils. In this greenhouse experiment, with quinoa (Chenopodium quinoa) as the host plant, we tested impacts of mineral nutrient (as manure and fertilizer) and biochar addition on mycorrhizal colonization of biochar. Paraglomus appeared to dominate the biochar packets, and the community of AMF found in the biochar was a subset (12 of 18) of the virtual taxa detected in soil communities. We saw differences in AMF community composition between soils with different edaphic properties, and while nutrient addition shifted those communities, the shifts were inconsistent between soil types and did not significantly influence the observation that Paraglomus appeared to selectively colonize biochar. This observation may reflect differences in AMF traits, with Paraglomus previously identified only in soils (not in roots) pointing to predominately soil exploratory traits. Conversely, the absence of some AMF from the biochar implies either a reduced tendency to explore soils or an ability to avoid recalcitrant nutrient sources. Our results point to a selective colonization of biochar in agricultural soils.
