“…An increase of plant available nutrients after biochar application has repeatedly been shown in field experiments (Farkas et al, 2020;Quilliam et al, 2012) and was identified as the reason for increased crop productivity on agricultural soils Olmo et al, 2014). But the effects of biochar have been shown to depend on the application rate Quilliam et al, 2012;Rogovska, Laird, Rathke, & Karlen, 2014) and soil properties, with greatest effects on acidic and nutrient-poor soils (Farkas et al, 2020;Haefele et al, 2011). Several factors may contribute to increasing nutrient concentrations in the biochar treatments.…”

“…Because of its low degradability, black carbon is almost ubiquitous in terrestrial soils. Besides its function as a potential long-term carbon sink in soils, black carbon may also increase soil nutrient supply and soil productivity (Farkas et al, 2020;Glaser, 2007;Major, Rondon, Molina, Riha, & Lehmann, 2010;Quilliam et al, 2012), water retention and erosion stability (Piccolo, Pietramellara, & Mbagwu, 1996) and microbial biomass and activity (Gaskin, Steiner, Harris, Das, & Bibens, 2008;Lehmann et al, 2011) and reduce the availability of toxic trace elements (Nie et al, 2018). Because of these positive effects, the amendment of soils with black carbon has been proposed as a sustainable management technique for enhancing soil productivity and long-term carbon storage (Glaser, Lehmann, & Zech, 2002;Lehmann, 2007).…”

The application of biochar to agricultural soils to increase nutrient availability, crop production and carbon sequestration has gained increasing interest but data from field experiments on temperate, marginal soils are still underrepresented. In the current study, biochar, produced from organic residues (digestates) from a biogas plant, was applied with and without digestates at low (3.4 t ha −1 ) and intermediate (17.1 t ha −1 ) rates to two acidic and sandy soils in northern Germany that are used for corn (Zea mays L.) production. Soil nutrient availability, crop yields, microbial biomass and carbon dioxide (CO 2 ) emissions from heterotrophic respiration were measured over two consecutive years. The effects of biochar application depended on the intrinsic properties of the two tested soils and the biochar application rates. Although

“…Due to the high amount of K in biochar, the K content depended on the amount of added biochar into soil [44]. Previous research indicated that biochar increases the amount of exchangeable K because of increasing the soil CEC [35,45]. However, in this study, the amount of exchangeable K was reduced (except for RHB-1), presumably as the biochar increased the uptake of K by the plants [43,46].…”

“…A number of studies have indicated that mixing biochar with soil can effectively improve the soil's physical and chemical properties [30][31][32][33], with biochar also improving the drainage, aeration, and water retention in clay [34], sandy [35,36], hard and compact [17], acidic [28,37], alkaline [38,39], and saline soils [4,[40][41][42]. Biochar can increase the nutrient uptake ability of plant roots [43][44][45][46].…”

In many areas, soil salinization is a major threat to ecosystems, agriculture, and food security. Human activities and climate change contribute to its increasing prevalence. In Thailand, Nakhon Ratchasima is the most severely affected province in the country’s Northeast region, and was selected for this study. The underlying geology and human activities both contribute to the problem in this area. The roots of field crops bring saline groundwater up into the rhizosphere. Evaporation at the soil surface leads to salinization, reducing crop growth, and, ultimately, rendering the soil barren. This research aimed to improve the quality of saline soil using rice husk biochar (RHB) to enable rice cultivation and limit evaporation. The study examined the effect of RHB incorporation on improving the soil properties. Jasmine rice variety KDML 105 was planted in cement rings (80 cm diameter) filled with saline sodic soil at pH 10.6, with a total sodium content of 0.83%, electrical conductivity (EC) of 68.6 dS/m, and sodium adsorption ratio (SAR) of 11707. The results indicated that RHB can significantly reduce the soil salinity, EC, Na+ content, and SAR value, while elevating the levels of available macronutrients, such as nitrogen, calcium, and magnesium. In addition, the study found that incorporation of RHB at a rate of 1.5 kg/cement ring was optimal for growing Jasmine Rice (KDML105) under these conditions.

“…Based on the results of the screening and microcosm experiments, the biochar from grain husks and paper fiber sludge was efficiently applied in long-term field experiments at two sites to improve the properties of an acidic sandy and a calcareous sandy soil; the field studies demonstrated that the applied biochar had positive direct and indirect influences on the acidic sandy soil [5,69,70].…”

The application of biochar (the by-product of biomass pyrolysis), as a soil amendment has been accepted as a sustainable solution to improve soil quality. The current study aims to establish a decision support tool for characterizing, ranking, and selecting biochars of different origins for soil improvement, thereby contributing to the development of a systematic approach, which lacks in the existing literature.The development of a Multi-Criteria Decision Support Approach applying a banded and weighted rating and scoring system allowed the selection and ranking of various biochars suitable for improving sandy soils before application. First, 14 selected, different biochar products (produced from industrial by-products, herbaceous, wood-based and manure-based feedstocks) were characterized with several physicochemical, biological and ecotoxicological methods taking into account both the technological and the environmental efficiency aspects of biochar utilization. Then, a system for the assessment and ranking of biochars for acidic, and calcareous neutral sandy soil improvement was developed, which could be flexibly adapted to different soil problems as well. Based on their performance in the tests, scores from (−5) to (+5) were assigned to each biochar. As a result, the grain husks and paper fiber sludge biochar was ranked as the most suitable for both acidic and neutral calcareous sandy soil improvement, with 55 and 43 scores, respectively (from the maximum 100). The applicability of this innovative multicriteria scoring-ranking system, as a tool for potential biochar users, was verified in microcosms and field-scale experiments, demonstrating the positive influence of this biochar on the acidic sandy soil.
