IE GSI GSNI Geochemistry Deeper Topsoil ‘S’ ICPar Ireland (ROI/NI) ITM

Topsoil is the upper surface layer of the soil. This data shows the type and the amount of chemicals in topsoil across the northern half of Ireland. The chemicals in the soil can be natural or made by humans. The data also tells us how much organic carbon is in the soil and the pH of the soil. Testing these soils helps us learn about where they came from or how they were made. This data allows us to map both the changing values of these chemicals and soil types across the country.

Knowing about the chemistry of soils is important for many people and industries. This data will help in land-use planning, mapping of natural resources, help to understand the impact of farming on the environment, and aid policy. Higher amounts of some chemicals in soils may also affect human and livestock health.

Farmers need to know the chemistry of their soils to understand the quality and fertility of the soils. This helps them decide if they should use fertilisers or not. This can improve the health of their animals and quality of their crops.

Soils can affect the quality of drinking water. If the quality of water is affected, it may need to be treated before people or animals can drink it.

The chemistry of soils can also help people looking for minerals. Minerals are materials taken from the ground used for things we need from mobile phones to the stones used to build roads and houses.

表土（topsoil）是土壤的上层表层。本数据集展示了爱尔兰北部全境表土中的化学物质类型与含量。土壤中的化学物质可分为天然成因与人为合成两类。该数据集同时涵盖了土壤有机碳含量与土壤pH值。对这些土壤样本开展检测，有助于我们了解其起源与形成过程。依托本数据集，我们可绘制出爱尔兰全境各类化学物质含量与土壤类型的动态变化分布图。

了解土壤化学特性，对诸多领域从业者与产业而言均具备重要价值。该数据集可服务于土地利用规划、自然资源测绘，助力理解农业活动对环境的影响，并为政策制定提供依据。土壤中部分化学物质含量过高，还可能对人类与畜禽健康造成威胁。

农户需掌握其耕地的土壤化学特性，以此判断土壤质量与肥力水平，进而决策是否需要施用化肥。此举可有效提升畜禽健康水平与作物品质。

土壤状况会影响饮用水质量。若水质受到影响，则需对其进行处理后方可供人类与畜禽饮用。

土壤化学特性还可为矿物勘探提供参考。矿物是从地下开采的物料，广泛应用于从手机制造到道路、房屋建筑用石料等各类生产生活场景。
