The need for facilitation of access to soil information has never been greater. Growing human population, shrinking land and water resources, soil pollution, climate change and unequal distribution of agriculture-oriented technology impact negatively on global food security. There has been a long-standing interest in developing low-cost and easily accessible soil field kits to measure different properties of agricultural soils in order to improve their agronomic capacity. Test strips in particular have provided a favoured method of obtaining soil nutrient status information since the 1970s. Today there is renewed interest in using semi-quantitative colorimetric methods in soil assessment due to incorporation of modern technological solutions, such as smartphones, which could in turn increase the accuracy and precision of the existing methods. In this paper, we propose streamlined testing procedures based on experience gathered that may be conducted prior to a field kit development involving test strips. Results from laboratory and field experiments are presented, highlighting important factors which ought to be taken into account at the commencement of test strip-oriented studies.

测试涉及纸条的土壤现场测试套件的新程序

对促进获取土壤信息的需求从未如此强烈。不断增长的人口、不断减少的土地和水资源、土壤污染、气候变化以及面向农业的技术分布不均对全球粮食安全产生了负面影响。长期以来，人们一直对开发低成本且易于获取的土壤田间工具包来测量农业土壤的不同特性以提高其农艺能力感兴趣。自 1970 年代以来，试纸尤其提供了一种获得土壤养分状态信息的首选方法。如今，由于采用了智能手机等现代技术解决方案，人们对在土壤评估中使用半定量比色法重新产生了兴趣，这反过来又可以提高现有方法的准确性和精确度。在本文中，我们根据收集的经验提出了简化的测试程序，这些经验可能在涉及测试条的现场套件开发之前进行。展示了实验室和现场实验的结果，强调了在开始面向试纸的研究时应该考虑的重要因素。
