“…Apart from clay, several other types of natural minerals can also aid in heavy metal remediation. For instance, zeolite, an alkaline aluminosilicate mineral with a well-developed microporous structure, immobilizes toxic metals via non-specific adsorption and the liming effect (Lee et al, 2019;Shi et al, 2009;Tahervand & Jalali, 2017). Diatomite, a naturally occurring siliceous mineral, is able to stabilize metals through surface complexation and non-specific adsorption, while promoting plant growth simultaneously due to its high Si content (Radziemska et al, 2020;Ye et al, 2015).…”

To promote human well-being and ensure healthy lives, the United Nations has set an ambitious sustainable development goal to reduce illnesses and deaths associated with soil contamination by 2030 (UN, 2015). Soil is a fragile, nonrenewable resource that is fundamental to life on earth (FAO, 2015;Hou et al., 2020). However, anthropogenic activities have led to widespread soil degradation and contamination (FAO, 2018). In Europe, there are approximately 2.5 million sites that are potentially contaminated by heavy metals and organic contaminants (EEA, 2018). In USA, 235,000-355,000 sites need to be remediated (US EPA 2004). In China, it is estimated that 16.1% of the nation's land contains

“…Perlakuan A2 dan A3 memperlihatkan bahwa peningkatan dosis FABA pada dosis kompos yang sama menurunkan kadar P-tersedia sebesar 21.0 ppm. Stout et al (1998) dan Lee et al (2019) menjelaskan bahwa penambahan abu terbang ke dalam tanah dengan kandungan P yang tinggi dapat mereduksi P-terlarut dengan membentuk ikatan Ca-P, Al-P, dan Fe-P.…”

Tanah berpasir memiliki kemampuan retensi air, kemantapan agregat, dan kadar unsur hara yang tergolong rendah. Untuk meningkatkan kualitas tanah berpasir ini dilakukan upaya pemberian berbagai dosis campuran kompos dan FABA sebagai amelioran. Tujuan penelitian ini yaitu menguji pengaruh pemberian kompos dan FABA sebagai bahan amelioran pada tanah berpasir terhadap karakteristik kimia tanah dan pertumbuhan tanaman tomat (Solanum lycopersicum). Percobaan pot dilakukan di Rumah Kaca Cikabayan, IPB University menggunakan Rancangan Acak Lengkap (RAL) dengan tujuh perlakuan dengan dua kali ulangan. Tanaman yang digunakan ialah tomat varitas SL 975. Parameter karakteristik kimia tanah yang diamati meliputi C-organik, N-total, P-tersedia, KTK, dan basa-basa dapat ditukar. Parameter pertumbuhan tanaman diamati pada lima minggu setelah tanam (MST). Hasil percobaan menunjukkan bahwa perlakuan A6 (1.950 gram kompos/pot dan 25 gram FABA/pot) menghasilkan kadar C-organik tanah yang tinggi, serta tinggi, jumlah daun, dan bobot basah tanaman tertinggi.

“…Heavy metal pollution and greenhouse gas (GHG) emissions present in arable soil have recently become a concern due to crop safety and the threat of global warming [1][2][3][4][5].

“…The application of amendments is a popular technique used to immobilize bioavailable heavy metals and reduce GHG emissions in soil because of its high efficiency, low cost, and ease of use [10][11][12][13]. The most commonly used amendments include organic materials (biochar, compost, and plant residuals), minerals (zeolite), and pH adjusters (lime, steel slag, and coal ash) [2,3,14,15].…”

Heavy metal pollution and greenhouse gas (GHG) emissions from soil are two major detrimental sources in the agriculture environment because of concerns about crop safety and global warming. Applying amendments on site is a common technique used for heavy metal remediation and the reduction in GHG emissions. This study aims to evaluate the effect of different amendments on the reduction in both bioavailable heavy metals and GHG emissions from soil. Four different amendments, namely bottom ash (BA), sintered material (SM), sintered material combined with lime (SM + L), and FeO (SM + FeO) were applied to upland fields, followed by maize (Zea mays L.) cultivation from April to October. Subsequently, SM + FeO treatment demonstrated the highest bioavailability reduction efficiency for As at 79.1%, and SM + L treatment had a high efficiency for the reduction in Cd and Pb by 64.6% and 41.4%, respectively. SM + FeO treatment also reduced bioaccumulated As and Pb in maize grain by 59.3% and 66.2%, respectively. Furthermore, SM + FeO treatment demonstrated the highest reduction efficiency for cumulative N2O emissions by 70.7%, compared to the control soil. Among the four different amendments, the efficiency of heavy metal and GHG emission reduction was in the following order: SM + FeO > SM + L > SM > BA. Overall, SM combined with FeO is a promising amendment for reducing and managing both heavy metal pollution and GHG emissions in soil.
