Toxicity induced by heavy metals is a major concern in agriculture as it decreases crops' growth and yield and leads to the deterioration of food quality. Recently, activated carbon has been identified as a possible solution. It can potentially improve crop nutrition and immobilize heavy metals in soil. That is why a glasshouse trial was conducted to investigate the effects of sugarcane bagasse-derived biochar on spinach growth and the availability of cadmium (Cd) and chromium (Cr) in artificially contaminated soil. The soil was placed in pots and contaminated with Cd and Cr at a rate of 10 mg kg −1 . Biochar was added to the soil at concentrations of 0 (control), 0 (contaminated control), 100, 150, and 200 g, and 10-day-old nursery spinach plants were transplanted to the pots. The results showed that applying 200 g of biochar significantly increased shoot weight (235 g), soil pH, electrical conductivity, and organic matter. The highest levels of Cd (27.71 mg kg −1 ) and Cr (20.44 mg kg −1 ) were observed in the contaminated control pots, while the lowest levels of Cd (16.80 mg kg −1 ) and Cr (9.80 mg kg −1 ) were found in pots treated with 200 g of biochar (2%). Similarly, the highest levels of Cd (35.80 mg kg −1 ) and Cr (40.24 mg kg −1 ) in the roots were found in the contaminated control pots, while the lowest levels of Cd (19.26 mg kg −1 ) and Cr (21.34 mg kg −1 ) were observed in pots treated with 200 g of biochar. Biochar application at a rate of 2% can immobilize Cd and Cr in the soil and improve chlorophyll contents, carotenoids, photosynthetic rate, transpiration rate, and stomatal conductance in spinach in Cd-and Cr-contaminated soils. Further long-term field studies will be necessary to determine the feasibility of applying biochar as an organic amendment for enhancing spinach growth and reducing Cd and Cr bioavailability in contaminated soil.

“…Generally, high soil nutrient contents drive plant photosynthesis, stomatal conductance and transpiration, ultimately promoting plant growth ( Qi et al., 2021 ). Biochar is a highly porous carbon structure that is rich in C, N and P nutrients and can be used as a soil amendment ( Rahi et al., 2022 ). Adding CSB can improve the soil pH and soil physical and chemical properties ( Figure 1D ).…”

Amending soil with biochar can reduce the toxic effects of heavy metals (HM) on plants and the soil. However, the effects of different concentrations of biochar on the properties and microbial activities in lead (Pb)-contaminated soils are unclear. In this study, two Pb concentrations were set (low, 1000 mg/kg; high, 5000 mg/kg), and five corn straw biochar (CSB) concentrations (0, 2.5, 5, 10 and 15%) were used to determine the response of the growth and rhizosphere of red clover (Trifolium pretense L.) (in terms of soil properties and bacteria) to CSB and Pb application. The results showed that 5% CSB better alleviated the toxicity of Pb on the shoot length of red clover, the biomass increased by 74.55 and 197.76% respectively and reduced the enrichment factor (BCF) and transport factor (TF) of red clover. Pb toxicity reduced soil nutrients, catalase (CAT), acid phosphatase (ACP) and urease activity, while the addition of CSB increased soil pH, soil organic matter (SOM) content and soil enzyme activity. 16S rDNA amplicon sequencing analysis showed that Pb toxicity reduced the diversity of rhizosphere bacteria in red clover and reduced the relative abundance of plant growth-promoting rhizobacteria such as Gemmatimonas, Devosia and Bryobacter. Spearman correlation analysis showed that the addition of alkaline CSB restored the relative abundance of rhizobacteria positively correlated with pH, such as Chitinophaga, Sphingomonas, Devosia and Pseudomonas, and thus restored the rhizosphere soil environment. This study demonstrates that 5% CSB can better alleviate the toxicity of Pb to red clover and soil. We also provide a theoretical basis for the subsequent use of beneficial bacteria to regulate the repair efficiency of red clover.

“…Tingginya nilai Er pada logam Cd disebabkan karena tingginya nilai faktor respon toksik logam Cd (Tr) yaitu sebesar 30 sebagai faktor pengali, sedangkan untuk logam yang lain nilanya hanya 5. Konsentrasi logam Cd yang tinggi pada tanah pertanian akan berdampak pada penurunan kesuburan tanah dan hasil panen hal tersebut disebakan karena logam Cd bersifat antagonis dengan unsur-unsur hara yang dibutuhkan oleh tanaman sehingga banyaknya logam Cd yang terserap oleh tanaman dapat mengambat penyerapan unsur lain yang dibutuhkan tanaman (Rahi et al, 2021). Remediasi tanah yang tercemar logam Cd salah satunya dapat dilakukan dengan aplikasi biochar karena biochar dapat mengubah bentuk kimia logam Cd menjadi pasif dan dapat mengurangi bioavailabilitas logam Cd (Tang et al, 2022).…”

Konsentrasi logam berat pada lahan pertanian sangat penting untuk dipantau karena berdampak pada lingkungan dan kesehatan masyarakat. Penelitian ini bertujuan untuk memberikan informasi mengenai tingkat kontaminasi logam berat pada lahan pertanian di Kabupaten Bandung (DAS Hulu Sungai Citarum) dengan menganalisis faktor kontaminasi, faktor resiko ekologi, indeks beban polusi dan tingkat akumulasi logam berat yang berasal dari sumber antrhopogenik. Penentuan titik pengambilan sampel tanah dilakukan secara grid pada satuan (unit) lahan pada peta penggunaan lahan. Pengambilan sampel tanah dilakukan dengan metode survey pada 273 titik lokasi. Sampel tanah dianalisis kandungan logam berat Pb, Cd, Cr, Co dan Ni, kemudian dianalisis pola sebaran dan kontaminasi tanahnya. Hasil penelitian menunjukkan bahwa nilai rata-rata konsentrasi logam Pb, Cd, Cr, Co dan Ni pada tanah masih berada di bawah batas kritis logam berat. Berdasarkan analisis kontaminasi dari faktor kontaminan (CF) dan potensi resiko ekologi (Er) menunjukkan bahwa konsentrasi logam Cd telah mencapai pada kategori sangat tercemar dan sangat berpotensi pada resiko ekologi. Tingkat pencemaran logam berat yang bersumber dari aktivitas anthropogenik menunjukkan kategori sedang hingga berat untuk logam Cd.ABSTRACTThe concentration of heavy metals in agricultural land is very important to monitor because it has an impact on the environment and public health. This study aims to provide information on the level of heavy metal contamination on agricultural land in Bandung Regency (the upstream watershed of the Citarum River) by analyzing contamination factors, ecological risk factors, pollution load index, and the level of accumulation of heavy metals from anthropogenic sources. Determination of the point of soil sampling is done on a grid on land units on the land use map. Soil sampling was carried out by survey method at 273 location points. Soil samples were analyzed for the heavy metal content of Pb, Cd, Cr, Co, and Ni, then the distribution pattern and soil contamination were analyzed. The results showed that the average concentration of Pb, Cd, Cr, Co, and Ni in the soil was still below the critical limit for heavy metals. Based on the analysis of contamination from the contaminant factor (CF) and potential ecological risk (Er) it shows that the concentration of Cd metal has reached the category of highly polluted and has a high potential for ecological risk. The level of heavy metal pollution originating from anthropogenic activities shows a moderate to a heavy category for Cd.
