Since about 2010, biochar became a research hotspot as its function of carbon sequestration firstly. Thereafter, biochar as a solid porous material could be used to dispose wastewater, improve soil quality, and reduce nutrient losses from soils. Recently, biochar has been widely accepted by governments, farmers and scientists to be applied to soil system as an emerging additive. There are abundant literatures (including short-communication, research article, technique report, review or meta-analysis) published to address the foregoing concerns following biochar application. Until now, comprehensive effects of biochar after applied to agricultural and forest soils are still need clarified, as well as the comparison between biochar and other soil additives.
Therefore, we want to organize a special issue regarding this topic in Phyton-International Journal of Experimental Botany. The following specific themes are of interest:
1) Observation of biochar’s effect on soil physiochemical properties, nutrient use efficiencies and plant growth.
2) Systematic assessment of the responses of nitrous oxide emission, ammonia volatilization, leaching and runoff (at least two pathways should be investigated) from agricultural and/or forest soils.
3) Demonstration of some harmfulness to soil quality and plant growth as results of direct-application of biochar.
4) Comparative study of how biochar and other soil additives (such as nitrogen inhibitor, bio-organic fertilizer, and stimulants) influence the above aspects.
Note: Just one aspects study (unless authors addressed the underlying mechanisms), property characterization of biochar, and only soil incubation experiment with no plant growing are not welcomed.

- Abstract Soil amendments containing carbonized materials increase the soil carbon reservoir, influence plant productivity, and, ultimately, help to clean the environment. There is data on the effect of such additions on soil physicochemical properties or plant growth, but few studies have focused on how these carbonized materials are distributed by termite species in the soil ecosystem. It is the first comprehensive study of the transportation of biochar (BC) by termite species under tropical environmental conditions in Pakistan. The present study was carried out to test the hypothesis that if termite species I) were involved in the distribution of biochar particles II)… More

- The Effect of Bamboo Charcoal Application on Soil Nutrients and Heavy Metals in Rice

- Abstract Soil heavy metal pollution is becoming more and more serious. Biomass charcoal application can play an important role in alleviating the toxicity of heavy metals in soils. Compared with other biochar, bamboo charcoal has more unique properties and may have a unique effect on heavy metal pollution. Zhejiang Province of Southeastern China is rich in bamboo resources. However, few studies related to bamboo charcoal application for heavy metal remediation in farmland were reported. In this study, four treatments with different amounts of bamboo charcoal application were set up through a field experiment, namely BC0 (no bamboo charcoal application), BC1 (2500 kg⋅ha−1),… More

- Effect of Reaction-Finished Solution of Hydrochar (HRFS) Application on Rice Grain Yield and Nitrogen Use Efficiency in Saline Soil

- Abstract We conducted a pot experiment to examine the feasibility of applying a reaction-finished solution of hydrochar (HRFS) to enhance rice production in a saline soil. With this purpose, HRFS was applied (0, 10, 20, 40, 60, 80 and 100 mL/pot) and rice yield and nitrogen (N) use efficiency (NUE) were determined. HRFS application significantly (P < 0.05) increased rice grain yield by 19.6%–30.0% compared to the control treatment (CKU, with N but without HRFS addition). Moreover, HRFS application promoted plant height and straw biomass of rice. Increases of rice yield were mainly achieved by increases in the number of panicles and grains… More

Abstract
There are few evidences on the effect of biochar on vegetable yield, nitrogen (N) and phosphorus (P) leaching losses under intensive vegetable production soil. The current field plot scale study evaluated responses of Chinese cabbage (Brassica oleracea L.) yield, N and P leaching losses using five N treatments of common N application rate according to local farmers’ practice (N100%), reducing 20% or 40% N fertilizer (N80% and N60%), and reducing 40% N fertilizer but incorporating 10 or 20 t/ha biochar (N60% + BC10 and N60% + BC20). Results showed that N80% and N60% decreased both the cabbage economic and leaf… More
