使用农药或化学土壤处理对农民的健康和环境造成问题，如有毒残留物和产品、土壤和水中自然氮平衡的破坏。低温等离子体技术是一种减少农药、化肥、提高产量、无残留的新技术。在这项工作中，使用介质阻挡放电（DBD）等离子体的土壤处理的基础研究集中使用的样品从缅甸，这是一个最常用的农药在东南亚地区。DBD等离子体产生的活性自由基有望成为农业用途化学农药或肥料的潜在替代品。对DBD反应器的电特性和温度变化进行了基础研究。采用DBD等离子体间接处理土壤，臭氧直接处理土壤。利用紫外可见分光光度计测定处理后土壤的紫外吸光度，确定处理后土壤中的臭氧浓度，并通过与对照土壤相比，土壤酸度和氮素含量的变化，研究臭氧对处理后土壤的有效性。结果表明，DBD等离子体间接处理的土壤可以获得植物生长和作物增产所必需的氮素营养，而不会产生化学残留。因此，等离子体农业可能是实现可持续农业的一个希望。
Pesticide use or chemical soil treatment causes problems to farmers' health and the environment such as toxic residues and the decay of natural nitrogen balance in products, soil and water. A non-thermal plasma technology becomes a novel technique to reduce pesticide and fertilizer and improve the production without chemical residues. In this work, the fundamental study on soil treatment using dielectric barrier discharge (DBD) plasma is concentrated using a sample soil from Myanmar which is one the most pesticide used in South-East Asia region. The reactive radicals produced by DBD plasma are expected to be potential alternatives to agricultural uses chemical pesticides or fertilizers. The fundamental studies on electrical characteristics and temperature variation of DBD reactor have been focused. The soil was treated with DBD plasma indirectly but with ozone directly. Thus, the UV absorbance of treated soil was measured using the UV visible spectrometer to confirm the ozone concentration in it. The effectiveness of ozone in treated soil was investigated with the changes in acidity and amounts of nitrogen nutrients comparing to the control soil. As a result, the nitrogen nutrient which is essential for plant growth and increasing in crop yields can be obtained from the soil indirectly treated by DBD plasma without chemical residues. Therefore, plasma agriculture could be a promise leading to sustainable agriculture.
