Determining the Effects of Silicon Content in Rice Husk Biochar of Southern Taiwan on the Germination of Corn Seeds (Zea mays L.) | Chapter 5 | New Visions in Science and Technology Vol. 10

 To our knowledge, there haven't been many studies on this topic in Southern Taiwan, where rice residues from farm areas offer a lot of potential. Farmers are unaware that simply adding a source of accessible silicon to the soil, they can improve crop production and increase stress and disease tolerance. Despite this, there are few publications on the Si effect of rice husk biochar on plant seed germination. In line with the foregoing, the goal of this research is to see how biochar made from pyrolyzed rice husks affects corn (Zea mays L.) seed germination and plant growth. The objective of such rice wastes is to make biochar out of them. The features of rice husk biochar were investigated in Pingtung County, using various types of combustion and temperatures in the process, as well as the impacts on corn (Zea mays L.) seed germination. Seven (7) different treatments were used in the experiment, including rice husk, rice husk biochar, and chemical fertiliser. To balance the quantities of rice husk biochar that may be integrated into clayey soils, the biochar treatments employed a 50/50 blend of biochar and soil. The impact of biochar on corn growth was investigated. Silicon content in rice husk biochar inhibited seed germination linearly, according to the findings. Silicon was found to be considerably damaging to corn seed germination in this study when Si concentration in rice husk biochar was more than 25 to 30 wt%, indicating that rising levels of silicic acid and amounts of the amendment exceeding 8-10 tonnes per hectare can impair germination rates. The apparent reduction in the total available amounts of heavy metals in bottom ash is the most encouraging consequence, implying that using binary mixes in plant formation is safe.
