“…According to the soil taxonomy map from U.S. Dept. of Agriculture, the soil in the study of Manuel Olmo et al [18] was similar to the soil in our study and the results were similar that biochar increased the yield by about 20%. …”

“…In Indonesia, the addition of biochar increased the yield of plants [17]. Olmo et al [18] investigated that olive-tree pruning-derived biochar amendment was related to a higher yield but the nutrient content was not obviously affected. The study in Kaoma, Zambia, Africa showed that maize cob-derived biochar dramatically increased maize yield by over 100% in different soils [19].…”

Biochar, a green way to deal with burning and burying biomass, has attracted more attention in recent years. To fill the gap of the effects of different biochar on crop yield in Northern China, the first field experiment was conducted in farmland located in Hebei Province. Biochars derived from two kinds of feedstocks (rice straw and corn stalk) were added into an Inceptisols area with different dosages (1 ton/ha, 2 ton/ha or 4 ton/ha) in April 2014. The crop yields were collected for corn, peanut, and sweet potato during one crop season from spring to autumn 2014, and the wheat from winter 2014 to summer 2015, respectively. The results showed biochar amendment could enhance yields, and biochar from rice straw showed a more positive effect on the yield of corn, peanut, and winter wheat than corn stalk biochar. The dosage of biochar of 2 ton/ha or 1 ton/ha could enhance the yield by 5%-15% and biochar of 4 ton/ha could increase the yield by about 20%. The properties of N/P/K, CEC, and pH of soils amended with biochar were not changed, while biochar effects could be related to improvement of soil water content.

“…The authors found that biochar (dairy manure and woodchip) application significantly reduced the soil bulk density from 1.22 to 1.00 g cm À3 and the values of bulk densities remained stable after 30 days of incubation. Moreover, Olmo et al (2014) showed that the addition of a biochar (produced from olive-tree prunings at 450 C) to a clay soil tended to reduce the soil compaction (i.e. the mechanical resistance of soil to root growth).…”

“…According to these authors, the exact mechanisms to explain these results are unknown but are probably linked to the biochar characteristics (biochar polarity and microporous structure). Similarly, Olmo et al (2014) studied the effects of the addition of a biochar (produced from olive-tree prunings at 450 C) to a clay soil in a field experiment during one wheat growing season (~6 months). The amended soil showed the highest moisture during the experiment (from 8 to 40% higher than the unamended soil).…”

“…This means that BC has a potential for the reclamation of saline-sodic soils. On the contrary, some authors have reported no effect on soil pH following BC addition, particularly when produced at low PT (<350°C) and when amending either alkaline or saline soils (Novak et al, 2009;De La Rosa et al, 2014;Olmo et al, 2014). This may be reflective of the strong influence of PT on BC pH (Janus et al, 2015), and also of the soil CaCO3 buffering effect (Olmo et al, 2014).…”

Crop response to soils amended with biochar: expected benefits and unintended risks

et al. 2017

Biochar (BC) from biomass waste pyrolysis has been widely studied due to its ability to increase carbon sequestration, reduce greenhouse gas emissions, and enhance both crop growth and soil quality. This review summarises the current knowledge of BC production, characterisation, and types, with a focus on its positive effects on crop yield and soil properties vs the unintended risks associated with these effects. Biochar-amended soils enhance crop growth and yield via several mechanisms: expanded plant nutrient and water availability through increased use efficiencies, improved soil quality, and suppression of soil and plant diseases. Yield response to BC has been shown to be more evident in acidic and sandy soils than in alkaline and fine-textured soils. Biochar composition and properties vary considerably with feedstock and pyrolysis conditions so much that its concentrations of toxic compounds and heavy metals can negatively impact crop and soil health. Consequently, more small-scale and greenhouse-sited studies are in process to investigate the role of BC/soil/crop types on crop growth, and the mechanisms by which they influence crop yield. Similarly, a need exists for long-term, field-scale studies on the effects (beneficial and harmful) of BC amendment on soil health and crop yields, so that production guidelines and quality standards may be developed for BCs derived from a range of feedstocks.
