“…They developed great enthusiasm for doing activities. Inconsistent with the study findings, it is found that Eco-garden is an essential arena in schools for transformative learning strategies from learning to earning (Boh et al, 2021;Harder et al, 2019;Mkhize et al, 2017) Consistent with the findings, it was found that urine diversion demonstrates its potential to separate and collect nutrients elegantly, and the desire to control pathogens and micro-pollutants helps in sanitation (Harada & FUJII, 2020). It was found that teachers' perceptions of the urine diversion toilet and using human urine as a fertilizer for the school garden were positive.…”

Urine separation toilets are a possible route for achieving maximum recovery and recycling urine nutrients. However, using fresh urine as agricultural fertilizer is problematic and controversial concerning hygiene, storage, distribution, and supply. The intervention of this study was implemented at a public high school in Nepal. This study explores the applicability of urine diversion toilets in the school setting to improve organic vegetable production from the school's Eco-garden and the status of improving sanitation. A urine diversion toilet was constructed, and hardware and software-based participatory interventions were undertaken in the schools' Eco-garden. It was found that the urine diversion toilet is useful in preventing surface water from being polluted and improving students' sanitation and hygiene behavior. When cultivating vegetables using human urine fertilizer and animal fertilizer in different plots of the same area, it is found that human urine as fertilizer increases by 40% more production of the vegetables in comparison with using animal fertilizer. It is concluded that urine-fertilized plots have more vegetables with nutrients than animal fertilizer. Human urine application could be effectively used as a nutrient fertilizer, a new area of scientific research in the research frontier.

“…Nitrogen is mainly in the form of urea (NH2-CO-NH2), phosphorus as phosphate (PO4 3-), and potassium ion (K -) and micronutrients are also present in a balanced form in human urine. Moreover, human urine is free from cadmium (Cd) and other heavy metals (Biswas et al, 2020;Boh et al, 2021;Palmquist & Jönsson, 2004).…”

“…Sorghum ( Sorghum bicolor L. Moench) is the fifth largest crop in the world and a crop that combines the resistance characteristics involves drought, salt, flooding, low temperature, and growth on barren lands, of which plays an important role in the world agricultural production and marginal barren lands exploitation 1 , 2 . After years of exploration and practice, sorghum has become the preferred crops for barren lands due to its excellent barrenness tolerance during pollination, it requires much less fertilizer nutrients than other dry-land crops such as maize and wheat 3 .…”

The development of nitrogen fertilizer green and efficient application technology by exploring the mechanism of efficient sorghum N use is important for sustainable development of sorghum industry as well as barren marginal land development and utilization. This study was conducted in 2018, 2019, and 2020 at Shenyang, China, using the nitrogen-efficient sorghum variety Liaonian No. 3 as material. The correlation between soil microbial species, diversity, and metabolic pathways with photosynthetic parameters and yield traits was analyzed to elucidate the mechanisms of nitrogen utilization and photosynthetic material production in sorghum under four fertilizer application patterns. The results showed that 17 populations of soil inter-root microorganisms were active in the organic fertilizer + 0 kg per hm2 of nitrogen (N0Y) model, and the abundance of two key populations, Comamonadaceae and Ellin5301, was significantly increased. Soil microorganisms regulated sorghum growth mainly through 30 pathways, focus including ko00540, ko00471, ko00072 and ko00550, of which ko02030 (Bacterial chemotaxis) and ko00072 (Synthesis and degradation of ketone bodies) played the most critical role. The functional analysis of soil microbial populations revealed that N0Y fertilizer model significantly reduced the intracellular trafficking, secretion. In addition, vesicular transport of microorganisms, amino acid transport and metabolism and nucleotide transport and metabolism played a key role in the regulation of population function. Overall, the N0Y model of N-efficient sorghum can achieve high levels of photosynthetic material production and higher yield formation through regulation of population activities and metabolic pathways of loamy microorganisms, resulting in reduced chemical N application and efficient green production of sorghum.
