The iSQAPER consortium brings soil quality to ones fingertips.
A newly developed Soil Quality Mobile App (SQAPP) has been launched during the last plenary meeting in Tartu, Estonia (12-15 June, 2018) of the iSQAPER project. SQAPP offers an easy-to-use tool that brings global soil data into the decision-making sphere of land users and other interested end users. SQAPP returns available soil quality information for any location in the world, simply picked by the user from a world map. Soil properties for that specific location are then shown and possibilities are offered to cycle through these values and to adapt them if necessary. Rather than scoring soil quality in absolute terms, the app scores the soil quality relative to the average soil quality within areas with similar soil and climatic conditions (so-called pedo-climatic zones). For example, 80% means that only 20% of the area of the selected pedoclimatic zone is considered to have a higher indicator value than the point location being assessed.
Depending on location as well as soil properties SQAPP will also give an overview of possible soil threats. These soil threats are scored based on general, scientifically-derived threshold values.
A summary shows the overall threat level and to which soil parameters and soil threats attention needs to be paid to reach a better soil quality. Moreover, recommendations are provided on how this can be achieved.
SQAPP is a test version and freely available on Google Play Store and the Apple Appstore. So, take your chance and green your fingers, help us testing the Soil Quality app.
Feedback is appreciated and can be send to the Wageningen University iSQAPER management team (see below). Project partners can also use the internal online Forum for discussion.
iSQAPER项目组参与人、世界土壤信息中心的白占国研究员等根据本项目所收集到的数据，分析总结农田管理措施对土壤质量的影响，该成果以在 "Agriculture, Ecosystems & Environment". 正式发表。 该成果针对中欧长期定位试验结果进行总结，并对主要四组管理措施对关系到土壤质量的5个因子进行分析. 该成果主要结论有：1) 免耕及有机农业条件下作物产量较低，但环境效益较好； 2)免耕、有机物添加，轮作以及有机农业有利于促进土壤有机质含量的增加；3) 与对照试验相比，土壤动物蚯蚓的数量是最敏感的指标；4)农田管理措施对土壤酸碱度的影响最小.
