“…These findings prove that diluted urine meets nutritional requirements of pepper seedlings in their early growth stages showing no adverse effects, attributable to the salinity of urine. Furthermore, it has been reported that high levels of salinity in soils can result in lower water absorption by the plant (Kirchmann and Pettersson, 1995;Simons and Clemens, 2003). Thus, the application of diluted urine at low levels of salinity could be a viable alternative to replace traditional fertilizers in vegetable production under greenhouse conditions.…”

“…This liquid can be used as a source of nutrients for agricultural production due to its content of nitrogen, phosphorus, potassium, and other natural elements (Kirchmann and Pettersson, 1995;Höglund, 2001;Germer, 2008;Dagerskog and Bonzi, 2010). Moreover, Ecological Sanitation (ECOSAN) recommends the use of urine to fertilize plants ( WHO, 2006), as it promotes sustainable production without causing pollution effects on soil and groundwater associated with the application of chemical fertilizers (Heinonen-Tanski and Van Wiljk, 2005;Pradhan et al, 2009;Germer et al, 2011).…”

La orina es considerada un fertilizante orgánico con un gran potencial en sistemas sustentables de producción agrícola, debido a su contenido de nutrientes; sin embargo, no puede ser aplicada directamente debido a su alto contenido salino, por lo cual es necesario un acondicionamiento previo para disminuir el pH y la salinidad. En el presente estudio se evaluó el efecto de diluciones de orina en agua (1, 2, 3 y 4 dS m-1), más dos tratamientos adicionales (solución Steiner y agua destilada) sobre el crecimiento y la absorción nutrimental de plántulas de chile Jalapeño. Las plántulas fertilizadas con orina diluida tuvieron mayor contenido de nitrógeno (35.4-59.9%) que las fertilizadas con solución Steiner. Además, no se observaron diferencias significativas en los parámetros de crecimiento entre plántulas fertilizadas con solución nutritiva Steiner, o con orina diluida a 1 dS m-1. Se concluyo que la orina diluida puede ser usada como una fuente nutricional alterna para la producción de plántulas de chile jalapeño.

“…It is proved by Kirchmann and Pettersson (1994), Vinneras et al (2003), Kiba (2005), Useni et al (2013) and Kimuni et al (2014) that human faeces are rich in nutrients and allow to obtain competitive yields to those obtained with mineral fertilizers. Human faeces remarkably improve the stock of nutrients in the soil, decreasing its acidity and can therefore be used as an amendment.…”

Improving soil fertility through organic fertilizers application has become a major factor that has enabled the world to feed billions of people. However, the required quantities of organic material are enormous, so it becomes necessary to combine different types of fertilizers to feed plants. The objective of this study was to evaluate the effects generated by the integration of human faeces to mineral fertilizers by bringing them to okra (Abelmoschus esculentus) crop. The trial was installed according to a 4×3 factorialdevice. Treatments in three repetitions, included four doses of human faeces (0, 1.75, 3.5 and 7 t haG 1 ) and three doses of inorganic fertilizers (0 and 150 kg NPK+100 kg urea as mineral fertilizer popularized and 75 kg NPK+50 kg urea as mineral fertilizer popularized halved). These fertilizers were applied alone or in combination and were compared to an unfertilized control. Obtained results showed that emergence rate increases when human faeces are made at low doses. As for the vegetative parameters, the results are similar regardless of the type or dose of made fertilizers. Without mineral fertilizers the different doses of human faeces generate low yields of okra. The application of 7 t haG 1 of human faeces combined with popularized mineral fertilizer dose halved (75 kg NPK+50 kg urea) afforded the highest yield (7.3 t haG 1 or an increase of 348% compared to unfertilized control treatment). In the present study, where access to chemical fertilizers is very limited, these results allow to save a half of usually made mineral fertilizer dose for the cultivation of okra.

This research demonstrated the feasibility of converting source-separated human urine into a solid fertilizer by means of continuous absorption and solar thermal evaporation using dried water hyacinth as adsorbent. In a preliminary experiment, the dried petioles of water hyacinth (DWH) absorbed urine in a mean rate of 18.78 ml·g −1 within 7 d, retrieving about 3.46% urine dissolved solids (UDS). In an advanced experiment, the DWH's capacity of urine absorption declined from an initial 2.73 L·kg, with a requirement of material change in about 25 effective days and an average ratio of 25 (L) to 1 (kg). Phosphorus (P 2 O 5 ) concentration in the adsorbent increased from 0.46% (material baseline) to 3.14% (end product), suggesting a satisfactory recovery of the element. In field application, the urine was discharged, not in wet weather, onto the DWH via a tube connected to a waterless urinal. There are several ways to use the UDS-DWH as P(K)-rich fertilizer, e.g., making soluble fertilizer for foliage spraying to encourage prolific flowering and fruiting. Apparently, utilization of water hyacinth waste to recover dissolved plant nutrient elements from source-separated urine will benefit the environment in a wide range of perspectives. The herein innovative use of water hyacinth is also expected to be useful in the recycling of certain dissolved hazardous materials.
