Soil microarthropods are intimately linked with health and fertility of soil as well as plant productivity. In India, despite their rich faunal diversity, information on soil microarthropods diversity and interactions with variety of edaphic factors is extremely limited. The present study is carried out to observe seasonal diversity of soil microarthropods in two different vegetable plots in Aligarh. The two vegetable plots chosen in this study where predominantly Tomato (Lycopersicom esculentum) and Brinjal (Solanum melongena, family-Solaneceae) have been grown and sapling has been sown in April when plants attained a height of approximately 6″. The samples collected randomly from a depth of 5 cm. @ of four samples per month for a period of 1 year. All microarthropods extracted with the help of Tullgren funnel apparatus. Among soil microarthropods collected, Collembolans have highest average monthly density (15.20 inds./sample) in brinjal plot and greatest abundance (18.7 inds./sample) in tomato plot. A highly significant negative correlation observed between Collembolans population with reference to soil temperature (r = – 0.867, P < 0.05), whereas available nitrogen showed positive correlation (r = 0.847, P > 0.05). Neutral pH level preferably influences the Collembolans as well as Acarina (mites). Peak population buildup of Collembola and Acarina was found in spring, and winter months, whereas sharp decline in summer months was observed. Therefore, this study clearly establishes the fact that habitat difference as well as edaphic factors play important roles in buildup of soil microarthropods population.

印度阿里加尔的两个不同蔬菜地中土壤节肢动物的季节性多样性

土壤节肢动物与土壤的健康和肥沃性以及植物的生产力密切相关。在印度，尽管它们具有丰富的动物多样性，但有关土壤微节肢动物多样性以及与多种营养因子的相互作用的信息极为有限。本研究旨在观察阿里加尔两个不同菜地中土壤节肢动物的季节性多样性。本研究选择的两个蔬菜地主要是番茄（Lycopersicom esculentum）和茄子（Solanum melongena）（植物茄科）已经生长，并且在4月植物高度达到约6英寸时播种了幼树。从5厘米的深度随机收集样品。@每月1次，共4次，为期1年。借助Tullgren漏斗提取所有节肢动物。在收集的土壤节肢动物中，Collembolans在茄子样地中的月平均密度最高（15.20 inds./样品），在番茄样地中的丰度最高（18.7 ins./样品）。Collembolans种群与土壤温度之间存在极显着的负相关性（r = – 0.867，P <0.05），而有效氮显示出正相关性（r = 0.847，P> 0.05）。中性pH值优选影响Collembolans和car螨（螨）。在春季和冬季，发现Collembola和Acarina的种群高峰出现，而在夏季，则急剧下降。因此，这项研究清楚地确立了这样一个事实，即生境差异和土壤因子在土壤微节肢动物种群的积累中起着重要作用。
