BACKGROUND
The declines in soil fertility associated with insufficient commercial fertilizers have resulted in the use of organic manure (human urine and faeces) as a source of fertilizers for production and cultivation of crop plants. The aim of this study was to assess perceptions of students and workers at the University of Limpopo (Medunsa Campus) regarding the fertilizing effect of urine.
METHODS
A total of 225 questionnaires were administered to staff and students. The questionnaire sought to establish the knowledge, attitude and behavioural changes as regards the use of urine as a fertilizer for the cultivation of vegetables.
RESULTS
Descriptive statistical analysis of the data indicated that 86.8% of the respondents were unaware of any human urine use as a fertilizer, 82.7% and 81.1% would not eat spinach and maize fertilized with urine respectively. Only 38.3% said they would eat vegetables fertilized with animal urine making it more tolerable as compared to human urine. Health reasons were given as the main reasons why respondents were unwilling to eat crops fertilized with human urine. However, 69.9% of the respondents [74.3% females, 69.9% students, 75.0% (27-36) age group] were willing to change their attitudes and unwillingness if they were better informed about the safety of human urine use for agricultural purposes.
CONCLUSION
Education, awareness and reassurance on the importance and safety of urine would have to be done so that urine for agricultural purposes could become more acceptable to people.
背景
与商业肥料不足相关的土壤肥力下降导致人们使用有机肥料（人尿和粪便）作为农作物生产和种植的肥料来源。本研究的目的是评估林波波大学（梅杜萨校区）学生和工作人员对尿液施肥效果的看法。
方法
共向工作人员和学生发放了225份问卷。该问卷旨在了解关于使用尿液作为蔬菜种植肥料的知识、态度和行为变化。
结果
对数据的描述性统计分析表明，86.8%的受访者不知道有人使用人尿作为肥料，82.7%和81.1%的受访者分别不会食用用尿液施肥的菠菜和玉米。只有38.3%的人表示他们会吃用动物尿液施肥的蔬菜，这使得动物尿液比人尿更容易被接受。健康原因被认为是受访者不愿意食用用人尿施肥的作物的主要原因。然而，如果能更好地了解将人尿用于农业目的的安全性，69.9%的受访者（74.3%为女性，69.9%为学生，75.0%为年龄在27至36岁之间的人群）愿意改变他们的态度和不愿意的状况。
结论
必须开展关于尿液重要性和安全性的教育、提高认识并给予保证，以便人们能更接受将尿液用于农业目的。
