| Biochars can be used as soil amendments for improving soil properties and crop yield. The objective of this research was to study the plant growth, yield, yield components, and seed quality, including nutrients and heavy metals (Pb, Cd, and Hg), in the soybean plant (Glycine max L. Merr.) and soil. The experiment was conducted from September 2010 to January 2011 in a greenhouse located in the Dan Khun Thot District, Nakhon Ratchasima Province, Thailand. The research comprised six treatments with four replicates in a completely randomized design. Quail litter biochar (QLB) at rates of 0, 24.6, 49.2, 73.8, 98.4 and 123 g per pot mixture were provided to soybean cv. Chiang Mai 60. The results showed that QLB could be used as a soil fertility improvement and... |

| Biochar can improve soil structure and water retention, enhance nutrient availability and retention, ameliorate acidity, and reduce heavy metal toxicity to plant roots. In this study, a basin experiment was conducted to investigate the effects of quail litter biochar (QLB) on the availability of Cd to physic nut (Jatropha curcas L.) plants. QLB was applied to the soil in which four new physic nut varieties (Takfa, Doi Saket, Lao, and Rayong) in factorial combinations at four levels (0, 5, 10, and 15 g kg-1 soil) to soil that contained 60.8 mg Cd kg-1. After transplanting plant height and canopy radius were measured every 2-mo and the number of leaves and branches at 6-mo, while yield components and Cd residues were measured at 8-mo intervals.
