No-till sugarcane (Saccharum spp.) systems is considered as an interesting option to reduce the cost of production and allow the conservation of both soil quality and biological activity. This study was conducted at a sugarcane mill in Goiatuba, in the state of Goiás, Brazil, which grows sugarcane variety SP 813250. An experiment based on a factorial design (2 × 2 × 2) was set up to compare the diversity of soil arthropods in sugarcane grown under no-till and conventional tillage systems, the efficiency of two methods used to extract soil arthropods (Berlese-Tullgren funnel and flotation in saturated salt solution), and the effects of sampling time (morning or afternoon) at different times of the year (September 2015, November 2015, April 2016, and June 2016). A total of 2776 arthropods belonging to 11 taxa were collected. Acari, Hymenoptera, and Isoptera were the most abundant arthropods (89.3%). The tillage system and sampling time did not affect soil arthropod diversity. The Berlese-Tullgren funnel method was more efficient at extracting arthropods in the rainy season (September and November), whereas the saturated salt solution method was more efficient in the dry season (April and June). The highest soil arthropod abundance was recorded in the rainy season. Our results suggest that the soil disturbance caused by tilling has no effect on soil arthropod diversity in sugarcane plantations.

免耕甘蔗（甘蔗spp。）系统被认为是降低生产成本并保护土壤质量和生物活性的有趣选择。这项研究是在巴西戈亚斯州Goiatuba的一家甘蔗工厂进行的，该工厂种植的甘蔗品种为SP813250。建立了基于析因设计（2×2×2）的实验，以比较土壤节肢动物的多样性在免耕和传统耕作系统下种植的甘蔗中，两种方法提取土壤节肢动物的效率（Berlese-Tullgren漏斗和饱和盐溶液中的浮选），以及采样时间（早晨或下午）的影响年份（2015年9月，2015年11月，2016年4月和2016年6月）。总共收集了2776个节肢动物，它们属于11个分类单元。Acari，膜翅目，和翼足类是最丰富的节肢动物（89.3％）。耕作制度和采样时间没有影响土壤节肢动物的多样性。Berlese-Tullgren漏斗法在雨季（9月和11月）提取节肢动物更有效，而饱和盐溶液法在旱季（4月和6月）提取效率更高。在雨季，土壤节肢动物的丰度最高。我们的结果表明，耕作引起的土壤扰动对甘蔗人工林中的节肢动物多样性没有影响。饱和盐溶液法在干旱季节（4月和6月）更有效。在雨季，土壤节肢动物的丰度最高。我们的结果表明，耕作引起的土壤扰动对甘蔗人工林中的节肢动物多样性没有影响。饱和盐溶液法在干旱季节（4月和6月）更有效。在雨季，土壤节肢动物的丰度最高。我们的结果表明，耕作引起的土壤扰动对甘蔗人工林中的节肢动物多样性没有影响。
