“…Therefore, vermicomposting can facilitate plant growth [11], and unlike pure animal manure, it is an excellent substrate for growing seedlings. Vermicomposting applications correspond to the improvement of conventional composting by adding earthworms to provide a better organic waste stabilization process [12]. Compared to conventional compost, vermicomposting contains higher levels of soluble nutrients and higher quality organic matter [13].…”

Dairy cattle farming produces large amounts of wastewater and it causes environmental pollution and eutrophication of rivers, but the nutrients in the waste could be recycled. Here, an improved vermicomposting system was applied to dairy farm wastewater, and wastewater with a nitrogen content of 100 mg/L and 200mg/L tested with different combinations of organic substrates such as cow manure and rice straw in rural solid waste. Results showed that earthworms could continuously grow, wastewater (N 100mg/L) mixed with rice straw corresponding to the most significant gained weight for Eisenia fetida earthworms (2.38 to 9.12-fold), and the earthworms’ weight was positively correlated with the C/N ratio, organic matter content, and pH. Compared to the initial state, the system significantly changed physicochemical parameters in nutrients, such as the percentages of total nitrogen, phosphorous, and potassium, which were found to increase in vermicomposting while organic matter content, C/N ratio, and cellulose declined as a function of the vermicomposting period, and the final vermicompost was better for the absorption of plants. These results suggest that continuous wastewater addition improved the effective transformation of organic waste to allow valorizing a broad range of organic residues, and avoid the risk of environmental pollution in dairy cattle farming.

“…The enhancement of these soil microbial indicators, following greater application rates, strongly indicated the benefit of vermicompost for soil microorganisms and their functioning. Vermicompost has been shown to provide a wide diversity of carbon and nutrient substrates for soil microorganisms (Lv et al, 2020). Soil respiration is regulated by two factors: the respiratory quotient and the total biomass of soil microorganisms.…”

IntroductionQuinoa a crop with high nutritional value has the widespread adaptability to different climates and there is an increased demand for this product in the world. Characterized by roots with extensive penetration capabilities and wide, alternate leaves giving rise to diverse inflorescences, quinoa plants exhibit variable heights ranging from 20 to 300 cm. The duration of their growth phase spans 95 to 125 days’ contingent upon cultivar selection and prevailing climatic conditions.Materials and methodsIn order to reduce chemical fertilizers consumption through using organic fertilizers a two-year study was conducted at the Research Farm of the University of Kurdistan, Iran, during the 2021–2022 growing seasons. In this study the effects of varying levels of irrigation and vermicompost application on soil characteristics and quinoa (Chenopodium quinoa) yield were investigated. The experiments were arranged as split plots within a randomized complete block design. The main factor consisted of four irrigation levels (50%, 75%, 100%, and 125% of quinoa’s water requirement), while the sub-factor encompassed four vermicompost application rates (0, 5, 10, and 15 tons per hectare). The irrigation method employed was a drip-tape irrigation system with a seven-day interval between irrigations, and water quantities were measured using a volumetric meter on the main pipeline.ResultsThe results demonstrated that the highest levels of available soil phosphorus (21.83 mg kg−1) and soil ammonium (36.08 mg kg−1) were observed in the treatment receiving 50% of quinoa’s water requirement combined with 15 tons per hectare of vermicompost. Additionally, the application of 15 tons per hectare of vermicompost led to the highest concentrations of soil nitrate (14.16 mg kg−1), available potassium (144.62 mg kg−1), and quinoa seed yield (1784.01 kg ha−1)). Over both years, the greatest activity of alkaline and acid phosphatase enzymes was noted in the treatment receiving 125% of quinoa’s water requirement in combination with 15 tons per hectare of vermicompost. Vermicompost application was found to enhance yield and ameliorate drought stress by enhancing soil physical and chemical properties and improving soil moisture retention.

Chinese medicine is widely employed in illness prevention and treatment. In recent years, the increased demand for Chinese medicine resources has resulted in a large quantity of waste created during industrialization. However, traditional methods for treating herbal residues, including burning, stacking, and burying, can cause significant environmental damage and resource waste. Furthermore, these application approaches have a low level of resource utilization and a low degree of utilization. Therefore, developing a classification management system is a necessary precondition for reusing Chinese herb residues for medicinal, feed, fertilizer, and energy resource reuse. This paper reviews the potential applications of Chinese herb residues in the extraction of active resources, composting, feed addition, bioethanol preparation, and pyrolysis to biochar, bio‐oil, and fuel gas. Overall, this work provides a foundation for further investigation into the high‐value usage model and resource reuse pathway of Chinese herb residues.
