Soil fertility (Natural capital)

This dataset shows the natural soil fertility of grassland and crop parcels in Overijssel, combined with yield loss (due to drought or wet damage). This results in four categories: 1. Fertile soil grassland, low yield loss. 2. Less fertile soil grassland, or fertile but high yield loss. 3. Fertile soils arable farming, low yield loss. 4. Less fertile soil arable farming, or fertile but high yield loss. This map is based on a model developed by the WUR (Graadmeter Services of Nature) and is based on natural soil fertility. This means that this map says nothing about the way a farmer manages his or her soil. This dataset is used in the ‘bottom’ map as part of the research into natural capital in Overijssel.本数据集展示了奥弗伊塞尔（Overijssel）地区草地与农田地块的自然土壤肥力，并结合了因干旱或湿害引发的产量损失情况，由此划分为四类： 1. 土壤肥沃的草地，且产量损失较低 2. 土壤肥力偏弱的草地，或土壤肥沃但产量损失较高 3. 土壤肥沃的耕地，且产量损失较低 4. 土壤肥力偏弱的耕地，或土壤肥沃但产量损失较高 该地图基于瓦赫宁根大学与研究中心（WUR，Graadmeter Services of Nature）开发的模型构建，核心依据为自然土壤肥力。这意味着本地图未考量农民对土壤的实际管理方式。本数据集作为奥弗伊塞尔地区自然资本研究的组成部分，被应用于‘底层’地图的制作中。
