“…The observed increase in leaf number in spinach could be ascribed to the synthesis of carbohydrates and phytohormones, resulting in a corresponding expansion of leaf area [36,37]. In a study assessing the effectiveness of cattle dung biogas digestate, it was observed that the application of inorganic fertilizer resulted in a greater increase in leaf area compared to the utilization of biogas digestate in spinach [38]. Roots play a vital role in providing stability and serving as a conduit for plants to absorb essential water and nutrients required for their survival and growth.…”

To achieve higher crop yields and maintain environmental conservation, it is imperative to adopt novel agricultural methods that improve both the quantity and quality of produce. The following study focused on investigating the effectiveness of integrated use of biogas slurry and inorganic nutrigation on spinach growth and nutrient uptake through drip irrigation. A field experiment was conducted using a split-plot design; spinach was cultivated with seven different treatments: biogas slurry nutrigation (BSN) (T1), integrated inorganic + organic nutrigation: 40% Recommended dose of fertilizer (RDF) + BSN (T2), 60% RDF + BSN (T3), 80% RDF + BSN (T4), 100% RDF (T5), slurry broadcasting (SB) (T6), and control (T7). The results showed that spinach grown with (T4) 80% RDF + BSN exhibited optimum plant height and leaf count compared to spinach under other treatments and was at par with T5 100% RDF for crop parameters. T5 treated plants demonstrated the longest roots, followed by T4 treated plants. The highest recorded yield of 5.72 tons ha−1 was achieved in treatment T5 with 100% RDF, followed closely by T4 with 80% RDF + BSN at 5.52 tons ha−1 and T3 with 60% RDF + BSN at 5.36 tons ha−1. These three treatments exhibited comparable yields, showcasing the effectiveness of incorporating biogas slurry nutrigation in conjunction with inorganic fertilizer for achieving high spinach yields. In terms of macronutrient content in spinach leaves, significant differences were found for nitrogen (N), phosphorus (P), and potassium (K) contents. Incorporating biogas slurry into the soil modified microbial enzyme activities, specifically dehydrogenase and phosphatase. Normally, alkaline phosphatase shows greater activity than acidic phosphatase, but the addition of biogas slurry equalized the enzymatic activity of both, establishing a harmonized enzymatic profile. Our results suggest that fertilizing spinach with integrated biogas slurry nutrigation (if properly filtered) + inorganic nutrigation through drip nutrigation is a viable strategy for improving the morphological parameters and productivity of spinach while also contributing to environmental preservation and a reduction in production costs.

“…Lü et al [68] also found that spinach will also achieve the maximum yield for the biogas slurry to water ratio of 1:4. Bridget [71] conducted an experiment using cow manure biogas slurry, while an inorganic fertilizer was used as a control group; it was found that spinach plants treated with the biogas liquid fertilizer had longer roots and higher zinc content. Zheng et al [72] found that a 20% concentration of biogas slurry had the greatest impact on tomato quality.…”

Anaerobic fermentation of organic waste, such as livestock manure, in biogas projects is an environmentally friendly and effective treatment method. The resulting biogas, mainly composed of methane, is a combustible gas with energy properties, while the digestate, containing nutrients such as nitrogen (N), phosphorus (P), potassium (K), and other organic matter, can be used for agricultural irrigation. This article analyzes the current situation of resource utilization of livestock manure in various countries and the progress of biogas projects. It introduces the process, composition, and commonly used filtration methods before applying the digestate to farmland. The summary focuses on the improvement of crop quality, enhancement of soil fertility and the risks of pollution, and environmental hazards associated with the utilization of biogas slurry. The limitations and corresponding solutions for the agricultural utilization of livestock digestate are discussed, and recommendations are made for the technology of digestate irrigation and application to farmland.

Septic tank waste can be used as a new alternative to be used as fertilizer because human excrement contains the availability of nutrients needed by plants. The research aimed to know the effect of liquid organic fertilizers dose, and plant media type of both to increase the growth and the production of plant spinach. The experimental design used was Block Randomized Design factorial with 9 treatments and 3 replicates. The first factor consists of 3 doses of fermented septic tank waste of human feces. Namely doses of 0 mL/plant (K1), 0,4 mL/plant (K2), 0,6 mL/plant (K3). The second factor is the planting medium consisting of 3 kinds of land or control (M0), land + husk charcoal (M1), land + Manure (M2). The observed variables include the number of leaves, plant height, root length, fresh weight of plant, root fresh weight, dry weight, root dry weight of the plant. The results showed that the fermented septic tank waste 0,6 mL (K3) influential real against the number of leaves. Granting planting media differ very markedly against all variable observations i.e. high number of plants, leaves, root length, fresh weight of plant, root fresh weight, dry weight, root dry weight of the plant. All variables are not found the existence of an interaction between fermented septic tank waste with the media.
