“…Adanya gejala-gejala tanah terdegradasi dan miskin kualitas biasanya berkorelasi langsung dengan deplesi bahan organik tanah (Magdoff and Van As, 2009). Akan tetapi, pencampuran biomasa organik pada tanah di daerah tropika basah cepat terdekomposisi, sehingga hanya memberikan solusi jangka pendek (Haefele, 2007. Biochar merupakan produk padat hasil pirolisis dari material organik (Mehmood et al, 2017;Clough et al, 2013) yang secara intrinsik resisten terhadap dekomposisi mikrobial (Clough et al, 2013;Kuzyakov et al, 2000;Marschner et al, 2000), sehingga secara potensial dapat tetap berada di dalam tanah selama ratusan tahun (Preston and Schmidth 2006). Biochar terbukti mempunyai pengaruh yang lebih kekal terhadap pH tanah dari pada CaCO3; serta dapat berpengaruh lebih besar terhadap siklus N ketimbang aplikasi kapur (Teutscherova et al (2017).…”

An application of biochar to the intensive weathered soils potentially can change physical and chemical properties of the soils, improved soil function and increased yield of crops. A meta-analyses evaluation showed a significant correlation between biochar and plants productivity, that means there are benefits of biochar application to the soils on plants productivities, that was increased 10%.This experiment was used Randomized Completed Block Design with 8 treatments and 3 replications. The treatments are: contr), 20 ton biochar ha-1, 40 ton biochar ha-1, 50 ton biochar ha-1, 60 ton biochar ha-1, 10 ton biochar + 10 ton poultry litter ha-1, 20 ton biochar + 20 ton poultry litter ha-1, 30 ton biochar + 30 ton poultry litter ha-1. The results showed biochar 20 ton ha-1 could increase significantly of plant heigh, number of punicles per clump, and the weight dried straw per clump. Whereas, application combination 20-30 ton biochar ha-1 + 20-30 ton poultry litter ha-1 could increase amount of tillers per clump, amound of punicles per clump, and weight dried straw (total biomass) per clump significantly.

“…Mankind is facing the challenge of feeding an increasing population by producing more food with optimal use of natural resources. The preservation of the quality of soils used for agricultural production is fundamental for this purpose, but climate change, water scarcity, and soil degradation have emerged as limiting factors for crop productivity [1]. Soil degradation in agricultural land is highly related to the depletion of its physical, chemical, and hydrological properties.…”

Physicochemical Changes in Loam Soils Amended with Bamboo Biochar and Their Influence in Tomato Production Yield

et al. 2021

Soil degradation and water stress in Costa Rica challenge the production of highly sensitive crops. This work is aimed at evaluating the physical and chemical changes in sandy loam (SL) and a silt loam (SiL) soil when amended with bamboo biochar while estimating the enhancement of tomato productivity. Biochar, obtained from Guadua Angustifolia bamboo feedstock, was mixed into sieved bulk soil substrate from the topsoil, from Andosol and Umbrisol groups, at application rates of 1, 2.5, and 5% (dry mass). Physicochemical and morphological properties of biochar such as pH, hydrophobicity, scanning electron microscopy images, helium picnometry, specific surface area by the Brunauer–Emmett–Teller (BET) method, CHNS, and ash content were determined. Soil hydrophobicity, acidity, electrical conductivity, cation exchange capacity and water retention, available water content, and air capacity were analyzed for the amended soils. Tomato yield was quantified after a harvest period of two months. The admixture of biochar did not significantly increase soil cation exchange capacity but increased water retention in the range of available water content. Class A (>200 g) tomato yield increased 350% in the SL and 151% in the SiL. Class B (100–200 g) tomato yields increased 27% in the SL but decreased about 30% in the SiL. Tomato yield response seems attributable to variation of water retention capacity, available water content, and air capacity. These results support the use of adapted water management strategies for tomato production based on soil physical changes of biochar.

“…Based on a literature and document study, interviews with project actors and onsite visits to biochar projects in Tanzania, the aim of this study is twofold: first, to map similarities and diversity of Tanzanian projects presented under the label of biochar, and second, to demonstrate how trade-offs between project objectives, local needs and regulatory capacities have been made in practice. The study is primarily to be viewed as an empirical contribution to the, as of yet, underdeveloped literature on the deployment of negative emissions technologies in LDCs in general (Anderson and Peters 2016;Buck 2016;Creutzig et al 2015;Fuss et al 2014;Geden 2015;Gough et al 2018) and on biochar use in developing countries and LDCs specifically (Mehmood et al 2017; for case studies in developing countries, see, for example, Joseph et al 2015;Scholz et al 2014;Shackley and Carter 2014). Moving beyond the empirical analysis, however, we will conclude by reflecting on the implications of our findings for future approaches to biochar as a mitigation technology in the context of the literature on offset mechanisms in international carbon markets or regimes in LDCs.…”

Biochar was recently included as a promising negative emissions technology (NET) in the Special Report on Global Warming of 1.5 °C published by the Intergovernmental Panel on Climate Change. Unlike other NETs, it can potentially be used to mitigate global climate change while adding to local resilience in countries highly exposed and sensitive to impacts of climate change, such as least-developed countries (LDCs). The study is as an empirical contribution to the, as of yet, underdeveloped literature on deployment of negative emissions technologies in LDCs in general and on biochar use in developing countries and LDCs specifically. Nine historical and existing biochar projects in Tanzania are mapped in order to analyse problems, goals and common trade-offs associated with smallto medium-scale biochar production in LDCs. The mapping is based on a literature and document study, interviews with project actors, and on-site visits to biochar projects during 2019. The paper gives support to the observation made in the biochar literature that while biochar has many potential socioeconomic and environmental benefits, combining them in one single project is difficult. It is concluded that implementing biochar projects in Tanzania will likely involve trade-offs between the development and subsistence strategies and needs of local communities, the motivational forces of different project participants, and the uneven regulatory capacity of the state. We end by reflecting on the use of biochar projects to offset carbon emissions made elsewhere.
