“…Incorporation of biochar steadily neutralized the soil pH value, and increased Mg and P availability in B-and BB-amended soils and Ca in BB-amended soil. These results are in line with those of previous reports (Yang et al, 2015), confirming the rate-dependent modifications of pH. Increases in exchangeable Ca and available P reflect the high base cations and P concentration of the biochar.…”

Incorporation of biochar into agricultural soils has been repeatedly proposed as an effective strategy to mitigate climate change with beneficial effects on soil properties and crop production. Results from previous field experiments showed that, when applied to vineyards, biochar amendment increased yield without a negative impact on grape quality, decreasing water stress during droughts and improving soil physical and chemical properties. Despite those positive impacts, the long-term effects of biochar treatment on soil fertility and ecological toxicity have seldom been studied at a real farm scale. We investigated the effects of biochar amendment on vineyard soil subjected to a single and a repeated biochar application focusing on total heavy metal concentration and availability, concentration and persistence of polycyclic aromatic hydrocarbons (PAHs), soil toxicity, and soil microbial community structure over a 5-year period. Our results showed that a longer term biochar application in a vineyard has no impact on soil microorganisms and does not retain toxic compounds (PAH and heavy metals). For the first time in biochar research, we investigate the biochar effect on a perennial crop and correlate the PAH retention with soil microbiota. Our research demonstrates that biochar application in a Mediterranean vineyard does not have a negative impact on soil ecology, reinforcing the perception that biochar is a sustainable option at farm scale, meeting the needs of agronomy and climate change mitigation.

“…. Yang et al (2015) mentioned that 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. Islami et al (2011) found that increases in maize yield following biochar application.…”

Globally, the current important concern is to waste minimization by producing biochar for crop production. The experiment was conducted at the research field from November 2015 to March 2016 to assess the growth and yield of maize (BARI Hybrid Bhutta 9) under variable rice husk biochar levels. The rice husk biochar levels 0, 1.5, 3, 5 and 7 t ha-1 constituted the treatment variables. Results revealed that growth and yield of maize were significantly influenced by different doses of rice husk biochar. Highest internodal length, stem diameter, leaf area index (LAI), crop growth rate (CGR), dry matter accumulation, grain yield and lowest net assimilation rate (NAR) were found when soil was treated with rice husk biochar @ 7 t ha-1 than in the biochar doses of @ 5, 3, 1.5 t ha-1 as well as 0 t ha-1 (Control). It was found that biochar increased soil pH from strongly acidic to slightly acidic. Biochar was found efficient in increasing soil organic carbon, nitrogen and sulphur and decreasing soil bulk density to favorable level. We concluded that the application of biochar increased growth and grain yield of maize and improved chemical and physical properties of soil.

“…Consequently, the low rate of 10 Mg ha −1 (~0.5 mass% assuming thorough incorporation in the top 15 cm soil layer) has been the most common select in field biochar applications [67]. Depending on the biochar source and the soil type, biochar amendment at as low as 0.1 mass% (2 Mg ha −1 ) may yield significant effects on plant growth [88]. Our research indicates that to secure the evident, long-term soil health improvement benefits, wood-and crop residue-derived biochars may be applied cumulatively at 2-5 mass% soil (40-100 Mg ha −1 ) and manure-derived biochars be applied at 1-3 mass% soil (20-60 Mg ha −1 ) to cropland.…”

Amending soil with biochar is a promising approach to persistently improve soil health and promote crop growth. The efficacy of soil biochar amendment, however, is soil specific, biochar dependent, and influenced by the biochar application programs. To maximize the benefits of biochar application, this paper proposes the 3R principles for applying biochar to soils: right biochar source, right application rate, and right placement in soil. The quality of biochar as a soil amendment varies significantly with the feedstock and the production conditions. Biochar products capable of everlastingly sustaining soil health are those with high stable organic carbon (OC) content and high water- and nutrient-holding capacities that are manufactured from uncontaminated biomass materials. Acidic, coarse-textured, highly leached soils respond remarkably more to biochar amendment than other types of soils. Soil amendment with particular biochars at as low as 0.1 mass% (equivalent to 2 Mg ha−1) may enhance the seasonal crop productivity. To achieve the evident, long-term soil health improvement effects, wood- and crop residue-derived biochars should be applied to soil at one time or cumulatively 2–5 mass% and manure-derived biochars at 1–3 mass% soil. Optimal amendment rates of particular biochar soil systems should be prescreened to ensure the pH of newly treated soils is less than 7.5 and the electrical conductivity (EC) below 2.7 dS m−1 (in 1:1 soil/water slurry). To maximize the soil health benefits while minimizing the erosion risk, biochar amendment should be implemented through broadcasting granular biochar in moistened conditions or in compost mixtures to cropland under low-wind weather followed by thorough and uniform incorporation into the 0–15 cm soil layer. Biochars are generally low in plant macronutrients and cannot serve as a major nutrient source (especially N) to plants. Combined chemical fertilization is necessary to realize the synergic beneficial effects of biochar amendment.
