“…Another study showed that the application of 120 g of rice husk biochar reduced the concentrations of trace elements such as Cd, Ni, and Mn but increased the concentration of Pb and Zn (Ndor et al, 2016). Pandey et al (2022) reported that the application of 3% biochar from Lantana camara and Tanacetum parthenium plants can reduce the solubility of micronutrients in the soil as well as avoid the toxic effects on plants.…”

Nickel is an important main resource mineral in Southeast Sulawesi, which has deposited around 97.4 billion tons, and undoubtedly, nickel exports emerged in national and regional economic growth. Mining activities were carried out through topsoil and subsoil stripping, resulting in damage to the soil ecosystem and making it difficult for soil to recover. A study was performed to evaluate the changes in soil chemical properties and the growth of patchouli (Pogestemon cablin Benth) on nickel-mined soil treated with rice husk charcoal (RHC). A randomized block design was applied in this study, including six treatments of RHC with three replications. The treatments were without RHC (control), 1.5%, 3.0%, 4.5%, 6%, and 7.5% of soil weight. Data were analyzed descriptively for soil chemical properties; meanwhile, ANOVA was applied for plant growth. The results revealed that RHC increased soil pH, organic C, CEC, and available P, and conversely, the application of 4.5% of RHC decreased soil Ni and Fe content by 65.43% and 40.47%, respectively. The application of RHC up to 6% increased significantly the plant height and number of leaves as well as the dry weight of patchouli. The present study concluded that the use of carbon-rich soil conditioners such as rice husk charcoal is an imperative measure to restore the nickel-mined soil.

“…Adsorben yang digunakan dalam penelitian ini adalah biokompos, campuran antara biochar dan kompos. Ndor et al (2016) memaparkan bahwa biochar sekam padi 120 g mampu menurunkan kandungan nikel sebesar 0,53 mg/kg namun tidak mampu menurunkan konsentrasi nikel pada tanaman bayam (Amaranthus cruentus). Biochar mampu menurunkan nikel tersedia di tanah sebesar 37,3 mg/kg akan tetapi belum mampu menurunkan serapan nikel pada tanaman jagung (Zia ur Rehman et al, 2016).…”

Penelitian bertujuan untuk mengkaji respon pertumbuhan tanaman kedelai, produksi dan kualitas kedelai pada tanah yang tercemar logam nikel yang diberi biokompos.Penelitian dilakukan di Rumah Kasa dan Laboratorium Terpadu BALINGTAN (Balai Penelitian Lingkungan Pertanian) Pati, Jawa Tengah dari bulan November 2018 – Februari 2019. Rancangan dasar yang digunakan dalam penelitian ini adalah rancangan acak lengkap pola faktorial 5 x 3 dengan 3 ulangan.Faktor pertama yaitu perlakuan konsentrasi cemarannikel (Ni) 0, 25, 50, 75, 100 ppm dan faktor kedua yaitu perlakuan dosis biokompos 0 ton/ha, 3,5 ton/ha dan 7ton/ha. Data dianalisis dengan analisis ragam dan dilanjutkan dengan uji berganda Duncan (Duncan’s Multiple Range Test). Hasil penelitian menunjukkanbahwa pada tanah yang diberi biokompos kurang dari 7 ton/ha dan semua tingkat cemaran menunjukkan penurunan pertumbuhandan produksi kedelai. Tanah yang diberi biokompos 7 ton/ha pada perlakuan konsentrasi cemaran nikel 25 ppm menghasilkan produksi kedelai (jumlah polong isi) setara atau sama dengan tanah tanpa cemaran nikel. Konsentrasi nikel dalam biji kedelai pada tanah yang tercemar nikel 25 ppm dengan diberi biokompos 7 ton/ha masih berada diatas ambang batas yang diijinkan. Kata kunci: kedelai, cemarannikel, biokompos

“…It aids in the formulation of many soil nutrients and can improve soil structure, plant growth and the increase of soil microbial population (Mensah and Ekeke, 2016). Charcoal is capable of absorbing organic and inorganic contamination in the soil due to its high cation exchange capacity (Ndor et al, 2016). Charcoal improves photosynthesis (Viger et al, 2013); it increases the formation of root nodules in legumes and invigorates the production of plant growth hormones (Lehmann, 2009).…”

The Response of African Yam Bean to charcoal and calcium chloride treatment in a crude oil polluted soil was carried out. 10kg of soil was polluted with 600ml of crude oil and was remediated with 500g of charcoal; the germinated seeds were pre-treated with 25g/l of Calcium chloride for 15mins before it was sown. The different treatments were: Control, 6% pollution, 6% pollution and charcoal, Charcoal only, Pre-treatment with calcium chloride, Pre-treatment with calcium chloride and 6% pollution, Pre-treatment with calcium chloride and 6% pollution and charcoal, Pre-treatment with calcium chloride and charcoal. Results showed that crude oil pollution impacted negatively on the parameters studied, the addition of materials (Charcoal and Calcium chloride) to the crude oil polluted soil improved the growth of African yam bean. Calcium chloride pre- treatment inhibited the emergence of AYB in a polluted soil. There was a significant difference (P>0.05) in the plant height, leave area, number of leaves, carbohydrate content, stem girth and root length, while treatments had no significant difference in the chlorophyll content and number of roots. The combined treatment (CaCl2 + Charcoal + pollution) did not show any significant impact on the growth and biochemical parameters when compared to the single treatments therefore; Charcoal and Calcium chloride are very good biostimulants but are more effective when they are applied separately.
