“…However, lime application increased Ca and Mg availability to the plants (Fig. 1), validating previous reports on the lime-induced improvement of basic cation levels (Court et al, 2018;Crusciol et al, 2019;Nguyen et al, 2021). This outcome was a consequence of Ca and Mg input (as CaO and MgO, respectively) and elevation of the soil pH from below 4 to 5 (Fig.…”

“…For example, an increase in the yield of corn and wheat by 28% and 13%, respectively, compared with the control, was revealed in the study of Salar F. Abriz et al [26]. The introduction of 2% biochar increased the yield of purple peristochetum (Pennisetum Pur-pureum Schumach) by 61% and by 82% with the introduction of 4% biochar compared with the control [27].…”

Effect of Biochar on Soil CO2 Fluxes from Agricultural Field Experiments in Russian Far East

et al. 2021

Agricultural soils are a major source of greenhouse gases. Biochar is a soil improver and, when applied to the soil, sequesters carbon. However, a different combination of soil and climatic conditions and biochar leads to different research results. In this research, the effects of 1 kg/m2 and 3 kg/m2 biochar application to clay soils on the CO2 flow in field experiments along two cropping seasons in the Russian Far East were investigated. Data showed that biochar significantly reduces the cumulative flow of soil CO2, compared with untreated field plots. In 2018, the greatest reduction in soil CO2 emissions (28.2%) with 3 kg/m2 of biochar was obtained, while in 2019, the greatest decrease in the cumulative CO2 flow at the application dose of 1 kg/m2 (57.7%) was recorded. A correlation between a decrease in the value of the cumulative CO2 flux and an increase in the biomass grown in the studied areas of agricultural crops during the season of 2018 was found.

The purposes of this study were to i) Examine the dynamics of physicochemical parameters of saline acid sulfate soil as influenced by biochar made from rice husk; and ii) Evaluate the influence of biochar on the soil quality index. A greenhouse experiment was carried out by mixing biochar with the tested soil at ratios of 0; 0.7; 1.5; 3, and 6% (w/w) and incubating for 100 days. Experimental soil samples were taken on days 5, 15, 30, 60, and 100 to analyze for 11 physicochemical parameters. The soil quality index (SQI) was calculated based on the principal component/factor analysis (PCA/FA). The results showed that biochar increased the exchangeable concentration of K, Mg, Ca, and pH value while reducing the exchangeable concentration of Fe, and Al, as well as the values of Cl-, H+, and exchange acidity in the soil. Biochar changed the electrical conductivity (EC) and Na parameters, increasing them in the first few measurements while decreasing them in the last measurements. Biochar increased the SQI of the tested soil, even with a low biochar application rate of 0.7% after 100 days of the experiment. The study suggests that biochar made from rice husk could be a potential amendment for ameliorating saline acid sulfate soil.
