The State Environmental Monitoring - The monitoring of the chemistry of arable soils

The spatial dataset concerns the monitoring of the chemistry of Polish arable soils, which is carried out as a part of the soil quality monitoring subsystem of the State Environmental Monitoring, coordinated by the Chief Inspector of Environmental Protection. The purpose of the research is to observe changes in a wide range of soil characteristics, especially chemical properties, occurring at specific intervals of time under the influence of agricultural and non-agricultural human activity. The research is carried out in 5-year cycles, starting from 1995, as part of the national network, which consists of 216 measuring and control points, located on agricultural soils throughout the country. The following parameters will be determined in the samples collected at designated soil profile sites: grain-size composition (8 fractions), % of humus, % of CaCO3, pH, hydrolytic acidity, exchangeable acidity, the contents of plant-assimilable forms of phosphorous (P2O5), potassium (K2O), magnesium (Mg) and sulphur (S-SO42-), the contents of: total nitrogen, organic carbon, polycyclic aromatic hydrocarbons, pesticides including organochlorine pesticides, exchangeable calcium, potassium, magnesium and sodium, electric conductivity and radioactivity. Moreover, calculated parameters will include: the C:N ratio, soil salinity, cation exchange capacity, the sum of exchangeable bases and the degree of base saturation. Additionally, the following parameters will be measured: the contents of soluble forms of: calcium, magnesium, potassium, sodium, aluminium, iron, phosphorous, manganese, cadmium, copper, chromium, nickel, lead, zinc, cobalt, vanadium, lithium, beryllium, boron, strontium and lanthanum.本空间数据集（spatial dataset）聚焦波兰耕地土壤化学监测工作，该工作作为国家环境监测（State Environmental Monitoring）体系中土壤质量监测子系统（soil quality monitoring subsystem）的组成部分开展，由波兰环境保护首席监察官（Chief Inspector of Environmental Protection）统筹协调。本研究的目的是观测在农业与非农人类活动影响下，特定时间区间内各类土壤特征（尤其是化学性质）的变化情况。本研究自1995年起以5年为一个监测周期实施，隶属于覆盖全国农业用地的国家监测网络，该网络共包含216个测控点位。在指定土壤剖面点位采集的样本中，将测定以下参数：粒度组成（8个粒级）、腐殖质占比、碳酸钙（CaCO3）占比、pH值、水解酸度、交换酸度、植物可吸收态磷（P2O5）、钾（K2O）、镁（Mg）及硫（S-SO42-）含量，以及总氮、有机碳、多环芳烃、包括有机氯农药在内的各类农药、交换态钙、钾、镁和钠、电导率及放射性活度。此外，还将计算得到以下衍生参数：碳氮比（C:N）、土壤含盐量、阳离子交换量、交换性盐基总量及盐基饱和度。另外，还将测定以下可溶性形态元素的含量：钙、镁、钾、钠、铝、铁、磷、锰、镉、铜、铬、镍、铅、锌、钴、钒、锂、铍、硼、锶及镧。
