The aim of this study was to examine the effect of human urine on soil quality and salinity through repeated applications, and compare it with the effects of synthetic fertilizer and non-fertilized treatments. Six different fertilizer mixtures were applied to pots of head cabbage: 100% tap water, 100% urine, 1:1 urine and tap water, 1:2 urine and tap water, 1:3 urine and tap water, and synthetic fertilizer. The study design was completely randomized design (CRD) with three replications of pot-based experiments. The growth and yield parameters of producing head cabbage (Brassica oleracea) among treatments were compared. Soil residual test of the optimum treatment was also conducted for the optimum treatment to examine the effect on its characteristics. The optimum yield was obtained from the application of 1:3 of urine and water, and comparable to the synthetic fertilizer (F = 21.78; p = 0.964). The difference in the electrical conductivity of soil was statistically significant (F = 2.324; p = 0.049) after three rounds of applications which should be considered during urine fertilizer utilization. Generally, urine contains nutrients, which can substitute synthetic fertilizer, at a dilution factor of three. However, education should be delivered to enhance public acceptance and to create awareness on urine collection, storage and application for sustainable utilization.

这项研究的目的是通过重复施用来检查人类尿液对土壤质量和盐分的影响，并将其与合成肥料和非肥料的影响进行比较。将六种不同的肥料混合物施于大白菜罐中：100％自来水，100％尿液，1：1尿液和自来水，1：2尿液和自来水，1：3尿液和自来水以及合成肥料。研究设计是完全随机设计（CRD），具有三个基于罐的实验重复。甘蓝型油菜的生长和产量参数。）之间进行比较。还对最佳处理进行了土壤残留测试，以检查最佳处理对土壤特性的影响。通过尿液和水的1：3施用可获得最佳产量，与合成肥料相当（F = 21.78；p = 0.964）。土壤电导率的差异具有统计学意义（F = 2.324；p= 0.049），在尿液肥料使用期间应考虑三轮施用。通常，尿液中的营养成分可以替代合成肥料，其稀释系数为3。但是，应该开展教育以提高公众的接受度，并提高人们对尿液收集，存储和应用的认识，以实现可持续利用。
