Abstract：
Long-term application of organic and mineral fertilizers can lead to changes in the elemental composition of agroecosystem components. Both the levels of nutrients and potentially toxic elements can change, as can the potential for these elements to be available to plants through changes in soil properties. Soil and plant samples of two species (pea Pisum sativum L. and oat Avena sativa L.) were collected from plots of a long-term field experiment on the application of mineral and organic fertilizers and their combinations to gray forest soils in the Vladimir region, Russia. Soil samples from the 0-20 and 20-40 cm layers were subjected to acid digestion to determine total element content. Mobile forms of elements were extracted from topsoil samples using acetate-ammonium buffer (pH 4.8). Sample preparation of pea and oat plant organs (stems, leaves, pods/ears) included sample digestion in a microwave sample digestion system ETHOS EASY (Milestone, Italy). The elemental composition of the samples was determined by inductively coupled plasma optical emission spectrometry (ICP-OES) using Agilent 5800 ICP-OES (Agilent Technologies, USA). The dataset includes concentration data for 34 elements, including rare earth elements, in these samples collected in 2021. The dataset also contains general agrochemical characteristics of soils of the experimental groups: pH of water and salt suspension, organic carbon content, mobile forms of phosphorus. The data can be valuable to researchers developing fertilizer application systems and modeling changes in the elemental composition of agroecosystems.
摘要：
长期施用有机和矿物肥料会导致农业生态系统成分的元素组成发生变化。营养素和潜在有毒元素的水平都会发生变化，通过土壤性质的变化，这些元素可能会被植物利用。从长期田间试验的地块中收集了两种（豌豆PisumsativumL.和燕麦AvenasativaL.）的土壤和植物样品，该试验涉及在弗拉基米尔地区的灰色森林土壤中施用矿物和有机肥料及其组合，俄罗斯。对0-20和20-40cm层的土壤样品进行酸消化以确定总元素含量。使用醋酸盐-铵缓冲液（pH4.8）从表土样品中提取元素的移动形式。豌豆和燕麦植物器官的样品制备(茎，叶子,豆荚/耳朵)包括样品在微波样品消解系统ETHOSEASY(里程碑，意大利）。样品的元素组成是通过使用Agilent5800ICP-OES（AgilentTechnologies，美国）。数据集包括34个元素的浓度数据，包括稀土元素,在2021年收集的这些样本中。该数据集还包含实验组土壤的一般农业化学特征：水和盐悬浮液的pH值，有机碳含量,磷的流动形式。这些数据对于开发肥料施用系统和模拟农业生态系统元素组成变化的研究人员来说是有价值的。
