“…Our study showed that suitable amounts of biochar (0.2%-1%) promoted the growth and development of aboveground and underground organs of tobacco, while higher amounts of biochar (5%) inhibited the shoot growth but promoted the root growth of tobacco. A study about the effect of biochar on maize growth and development also led to the similar conclusion that, the growth and physiology of maize was improved at 1.0% biochar level as compared to other biochar levels (0.5 and 1.5%) (Ahmad et al, 2015). And a substantial increase was found in plant height, shoot dry weight and maize yield with biochar addition compared to the untreated control (Abid et al, 2014).…”

A Pot experiment was conducted to study the effect of straw biochar application on growth, nutrient absorption of flue-cured tobacco and soil fertility. The tobacco height, productive leaves and leaf area were all promoted by biochar application at appropriate levels (0.2-1.0%), while they were inhibited by high-level (5%) biochar application. Growth of the root system was promoted more extensively by biochar application at all levels tested than the aboveground organs, with 5% biochar addition resulting in the highest root-shoot ratio, which also delayed the senility of tobacco root system including lateral roots. The taproot length, lateral roots and root-shoot ratio of tobacco all increased at early growth stage but decreased at latter growth stage. The biochar had different effect on N, P and K concentrations of tobacco organs. Large amount of biochar addition (5%) decreased N and P contents, but significantly increased K content in tobacco organs. Moreover, the soil bulk density decreased, while an increase was observed in soil pH and soil nutritional indicators including, organic carbon, alkali-hydrolysable N, available P and K, with the soil nutrient level highest in the 5% biochar treatment. Our results induced that 0.2-1.0% levels of straw biochar application might be appropriate in the tobacco field.

“…This is indicative of the synergistic effect of biochar when applied with fertilizer sources. Such a synergistic effect has been reported in various studies such as for the increased production of maize by Yamato et al [29] through combined biochar and fertilizer; Yamato et al reported a 4-12 times higher yield of rice and sorghum when combined with fertilizer and compost [14,30] and reported increases in corn yield through increased P availability and uptake when biochar combined with arbuscular mycorrhiza (AM) fungal spores [31,32].…”

Biochar holds promise as a soil amendment with potential to sequester carbon, improve soil fertility, adsorb organic pollutants, stimulate soil microbial activities, and improve crop yield. We used a hardwood biochar to assess its impact on corn (Zea mays) grain, biomass yields and greenhouse gas emission in central Kentucky, USA. Six treatments included as follows: control (C) with no amendment applied; poultry litter (PL); biochar (B); biochar + poultry litter (B + PL); fertilizers N-P-K (F); and biochar + fertilizers (B + F). Biochar was applied only once to plots in 2010 followed by rototilling all plots. Only PL and fertilizer were applied annually. When applied alone, biochar did not significantly increase dry matter, grain yield, and N-P-K uptake. There was also no significant difference between the combined treatments when compared with PL or F applications alone. We observed a slight increasing trend in corn grain yield in the following 2 years compared to the first year from biochar treatment. Poultry litter treatment produced significantly greater N2O and CO2 emissions, but emissions were lower from the B+PL treatment. We conclude that this biochar did not improve corn productivity in the short term but has potential to increase yield in the long term and may have some benefit when combined with PL or F in reducing N2O and CO2 emissions.

This positive impact of biochar might be due to its ability to enhance nutrient‐ and water‐holding capacity, making soil conditions more conducive to plant growth .…”
