“…30. Preliminary experiments showed that C:N ratios higher than 30 made the composting process slow, as has also been reported in other studies [4,5]. No bulking agent was added to the mixes.…”

“…The composting stabilization times using sugarcane bagasse, sawdust, urban trees, napier grass, and cotton were 91, 145, 91, 91, and 84 days, resulting in composts with final C:N ratios of 15, 23, 15, 16, and 11, respectively. Composting periods of 90 days with the addition of natural zeolite [4], 75 to 180 days without any addition [9], and 147 days with the addition of urea [5] have been reported by other authors.…”

“…Nutrient levels were higher with the cotton-chicken compost than with the other composts (e.g., 53.41 g kg −1 N, 3.43 g kg −1 P, and 13.34 g kg −1 K for C00), followed by the napier−chicken compost N00 (40.67 g kg −1 N, 2.30 g kg −1 P and 10.95 g kg −1 K) (Table 1). The nutrient composition of composts varies with the chemical properties of the raw materials and the composting temperature, but other factors may also be important such as moisture, C:N, aeration, and pH [4,5,9]; these factors could help explain the vari-ations in nutrients among different types of organic substrates. The quantity of biochar added to soil is expected to have an impact on the extent to which nutrient levels and soil processes are affected [11].…”

“…As a result, the composition of the growing medium of greenhouse-grown plants must be optimized to sustain and nourish the plants. Several organic media/substrates for growing plants, including composts, peat, expanded clay, bark, coir, perlite, and vermiculite have been evaluated by different researchers [3][4][5][6]. Composting aids in the recovery of nutrients and other organic compounds from organic wastes, thereby increasing their availability to plants.…”

“…Plant residues provide varying C:N ratios [2] and could work well in adjusting the chemical composition and stabilizing the physical properties of animal wastes. Biochar has also been suggested as a suitable material for stabilizing the physical properties of animal wastes [4]. Biochar is charcoal produced through pyrolysis by exposing plant matter to elevated temperatures in a low-oxygen environment [11].…”

Soil amendments, such as composts and biochar, are currently widely used as substrates in container gardening. Although different types of wastes have been used in composting, formulating growing mediums for specific plants using different materials is necessary. In the present study, organic substrates comprising mixtures of (a) broiler chicken wastes composted with sugar bagasse, sawdust, urban tree, napier grass, or cotton residues, and (b) five different proportions of biochar (0%, 15%, 30%, 45%, and 60%) were used to produce mineral and flavonoid-rich parsley plants. The sawdust-based substrate led to the highest yields (27.86 g pot−1 on average), regardless of the amount of biochar added; however, this substrate resulted in plants with no appreciable antioxidant activities. Plants grown using the tree-based substrate had moderate yields (16.95 g pot−1), and the highest phenolic levels (e.g., 7.93 mg GAE g−1) and antioxidant activities (DPPH scavenging activity over 11.17 g TE g−1). Such activities were better described by the presence of apigenin-7-apiosylglucoside and diosmetin-apiosylglucoside. Moderate yields were also obtained with the cotton-based substrate; however, such yields were only obtained at biochar proportions greater than 30%; this substrate led to the highest K contents (47.19 g kg−1). The lowest yields (3.20 g pot−1) and N (20.96 g kg−1), P (1.33 g kg−1), K (33.26 g kg−1), and flavonoid (13.63 mg CE g−1) contents were obtained with the napier-based substrate. However, this substrate led to the production of parsley plants with the highest levels of anthocyanins (0.40 mg CGE g−1), which may have accumulated as stress sensors and defense components. The bagasse-based substrate also led to high yields and appreciable flavonoid contents with 60% biochar. In most cases, no linear relationship was found between the biochar amount and the chemical parameters evaluated. Overall, the substrates formulated using urban tree residues had higher suitability for parsley development than those formulated using sugar bagasse, sawdust, napier grass, or cotton residues.
