通过测定红甜菜根中微生物、营养物质和抗氧化剂甜菜苷含量，研究人尿和木灰施肥对红甜菜产量和品质的影响。红甜菜施肥133公斤N/公顷的矿物肥料，尿和灰，只有尿没有肥料作为对照。矿物施肥的植物和尿和灰施肥的植物也收到89公斤P/公顷。尿和灰，只有尿肥料生产1720和656公斤/公顷的根生物量，分别比从矿物肥料获得。在矿物质施肥和尿和灰施肥的红甜菜根中检测到很少的粪大肠菌群和大肠杆菌噬菌体。红甜菜根中蛋白质和甜菜苷含量在所有处理中相似。总之，本研究表明，尿液与灰分或无灰可以提高红甜菜的产量，而且微生物质量和化学质量与矿物肥料产品的情况相似。
The objective of this study was to evaluate the effect of human urine and wood ash fertilization on the yield and quality of red beet by measuring the microbial, nutrient, and antioxidant (betanin) content of the roots. Red beets were fertilized with 133 kg of N/ha as mineral fertilizer, urine and ash, and only urine with no fertilizer as a control. The mineral-fertilized plants and urine- and ash-fertilized plants also received 89 kg of P/ha. Urine and ash and only urine fertilizer produced 1720 and 656 kg/ha more root biomass, respectively, versus what was obtained from the mineral fertilizer. Few fecal coliforms and coliphage were detected in mineral-fertilized and urine- and ash-fertilized red beet roots. The protein and betanin contents in red beet roots were similar in all treatments. In conclusion, this study revealed that urine with or without ash can increase the yield of red beet and furthermore the microbial quality and chemical quality were similar to the situation in mineral-fertilized products.
