Tong X, Song Q, Wang L, Hong Z, Dong Y, Jiang J. Effects of biochars derived from four crop straws on a Cd-polluted cinnamon soil. ENVIRONMENTAL SCIENCE AND POLLUTION RESEARCH INTERNATIONAL 2023; 30:24764-24770. [PMID: 36692727 DOI: 10.1007/s11356-023-25440-8] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 10/24/2022] [Accepted: 01/16/2023] [Indexed: 06/17/2023]
Abstract
Crop straw biochar is an efficient and low-cost alternative amendment for heavy metal immobilization in acidic soil. However, reports on the effect of these biochars on the amendment of actual Cd-polluted calcareous soil are limited. Therefore, four biochars, derived from peanut, rice, maize, and wheat straws, were applied to determine the changes in the chemical properties of alkaline cinnamon soil and effects on Cd immobilization. The results showed that the cation exchange capacity and the contents of organic C, Mehlich-3 K, and Mehlich-3 P in the biochar-amended soil increased by 4.87-22.02%, 68.78-218.83%, 1.9-10.3 times, and 19.18-74.40%, respectively, indicating the potential high performance of biochar in improving soil fertility and productivity. The Community Bureau of Reference sequential extraction results showed that decrease in acid-extractable Cd resulted in a reduced availability of Cd. Thus, crop straw biochar could be a promising alternative for soil Cd decontamination and fertilization.

Rasul M, Cho J, Shin HS, Hur J. Biochar-induced priming effects in soil via modifying the status of soil organic matter and microflora: A review. THE SCIENCE OF THE TOTAL ENVIRONMENT 2022; 805:150304. [PMID: 34536873 DOI: 10.1016/j.scitotenv.2021.150304] [Citation(s) in RCA: 13] [Impact Index Per Article: 6.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 05/27/2021] [Revised: 07/23/2021] [Accepted: 09/08/2021] [Indexed: 06/13/2023]
Abstract
Biochar (BC) application has the potential to be integrated into a carbon-trading framework owing to its multiple environmental and economic benefits. Despite the increasing research attention over the past ten years, the mechanisms of BC-induced priming effects on soil organic carbon mineralization and their influencing factors have not been systematically considered. This review aims to document the recent progress in BC research by focusing on (1) how BC-induced priming effects change the soil environment, (2) the factors governing the mechanisms underlying BC amendment effects on soils, and (3) how BC amendments alter soil microbial communities and nutrient dynamics. Here, we carried out a detailed examination of the origins of different biochar, its pyrolysis conditions, and potential interactions with various factors that affect BC characteristics and mechanisms of C mineralization in primed soil. These findings clearly addressed the strong linkage between BC properties and abiotic factors that leads to change the soil microclimate, priming effects, and carbon stabilization. This review offers an overview of a fragmented body of evidence and the current state of understanding to support the application of BC in different soil environments with the aim of sustaining or improving the agricultural crop production.

Mkhonza NP, Muchaonyerwa P, Buthelezi-Dube NN. Carbon dioxide emission, nitrogen mineralisation and spinach dry matter yield in a loamy humic soil amended with lime and poultry manure. ENVIRONMENTAL MONITORING AND ASSESSMENT 2022; 194:110. [PMID: 35048201 DOI: 10.1007/s10661-021-09730-7] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 06/04/2021] [Accepted: 12/23/2021] [Indexed: 06/14/2023]
Abstract
While application of lime and poultry manure (PM) increase availability of mineral N in acidic humic soils (> 1.8% organic carbon), these amendments enhance decomposition of soil organic carbon (SOC) increasing carbon dioxide (CO2) emissions. This study investigated the effects of co-application of PM and lime on (i) CO2 emission, (ii) concentration of mineral-N and (iii) spinach dry matter yield and nutrient uptake in a humic soil. Two incubation experiments were set up for 84 days to determine (i) CO2 emission and (ii) mineral-N on soils from the 0-10- and 10-20-cm depths. The treatments were PM (10 t ha-1), lime (12 t ha-1), PM + lime and unamended control. Same treatments (with inclusion of inorganic fertilisers) were applied to a pot trial using soils (0-10-cm depth) that were pre-incubated for 0, 14 and 35 days before planting spinach, and dry matter yield and N uptake were determined. Co-application of PM and lime significantly decreased ammonium-N in soil at both depths but increased nitrate-N and CO2 emission than lime alone. Poultry manure significantly increased ammonium-N and CO2 emission at 0-10-cm depth. For all treatments, cumulative CO2-C was significantly higher at 0-10 cm. Dry matter yield for PM + lime and lime + mineral N was higher than when separately applied. Pre-incubation of soils with lime and PM, separately or in combination, increased dry matter yield. These findings imply that application of PM and lime in humic soils increases mineral-N availability and crop productivity, especially when pre-incubated for 35 days, whilst the increase in CO2 emission could result in the decrease of SOC.

Abstract
Different soil amendments are applied to improve soil properties and to achieve higher crop yield under drought conditions. The objective of the study was to investigate the role of biochar for the improvement of wheat (Triticum aestivum L.) growth and soil biochemical properties under drought conditions. A pot experiment with a completely randomized design was arranged with four replications in a wire house. Drought was imposed on two critical growth stages (tillering and grain filling) and biochar was applied to the soil 10 days before sowing at two different rates (28 g kg−1 and 38 g kg−1). Soil samples were collected to determine the soil properties including soil respiration and enzymatic parameters after crop harvesting. Results showed that water stress negatively affects all biochemical properties of the soil, while biochar amendments positively improved these properties. Application of biochar at 38 g kg−1 provided significantly higher mineral nutrients, Bray P (18.72%), exchangeable-K (7.44%), soil carbon (11.86%), nitrogen mineralization (16.35%), and soil respiration (6.37%) as a result of increased microbial activities in comparison with the 28 g kg−1 rate.

Shetty R, Vidya CSN, Prakash NB, Lux A, Vaculík M. Aluminum toxicity in plants and its possible mitigation in acid soils by biochar: A review. THE SCIENCE OF THE TOTAL ENVIRONMENT 2021; 765:142744.

Abstract
Toxicity of aluminum (Al) is a serious problem for agricultural plants, especially due to excessive soil acidification caused by continuous intensive agriculture and modified environmental conditions related with global climate change. Decreased root elongation and shoot growth, reduced biomass production, nutrient imbalance and altered physiological and metabolic processes are responsible for lower yield and crop quality and therefore, decreased variability and productivity of the land. Recently, biochar is gaining popularity for ameliorating metal toxicity in soils. However, there is a lack of comprehensive information regarding the effects of biochar and its functioning. Multiple mechanisms are involved in ameliorating Al toxicity in which inherent properties of biochar influencing Al adsorption, absorption, complexation, cation exchange and electrostatic interaction are considered to play major roles. Modification of biochar to enhance these mechanisms might hold the key for long term solution. Present review indicates gaps for further research. Long term field studies are needed to understand the effects of biochar on Al toxicity.

Effect of different biochars on acid soil and growth parameters of rice plants under aluminium toxicity. Sci Rep 2020; 10:12249. [PMID: 32704053 PMCID: PMC7378052 DOI: 10.1038/s41598-020-69262-x] [Citation(s) in RCA: 33] [Impact Index Per Article: 8.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/20/2019] [Accepted: 07/10/2020] [Indexed: 11/30/2022] Open
Abstract
Biochar is known to decrease the soil acidity and in turn enhance the plant growth by increasing soil fertility. Major objective of the present work was to understand the effect of biochar treatment on alleviation of soil aluminium (Al) toxicity and its role in enhancing plant growth parameters. Soil incubation study was conducted to understand the effect of biochar (Eucalyptus wood, bamboo, and rice husk) on soil pH, soluble and exchangeable Al in soil with and without Al addition. Another independent pot experiment with rice crop (Oryza sativa L. var. Anagha) was carried out for 120 days to examine the effect of biochars on soil properties and growth parameters of rice plants. Wood biochar application to soil at 20 t ha−1 was found to be highly consistent in decreasing soil acidity and reducing soluble and exchangeable Al under both studies. We conclude that wood biochar at higher dose performed better in reducing soluble and exchangeable Al in comparison to other biochars indicating its higher ameliorating capacity. However, rice husk biochar was effective under Al untreated soil, indicating the role of Si-rich biochars in enhancing plant growth.
