RETRACTED: Activities of functional enzymes involved in C, N, and P conversion and their stoichiometry during agricultural waste composting with biochar and biogas residue amendments

g-C3N4promotes agro-ecosystem productivity: a case study for rice

“…BG, DHA, NAG, UE, LAP and AP are the main extracellular enzymes involved in soil C, N and P transformation. 36 The C cycle related enzymes (BG, DHA and NAG) were stimulated by g-C 3 N 4 and Fe–C 3 N 4 at the different fertilization periods. The N and P associated enzymes UE, LAP and AP did not change significantly.…”

“…Fresh soil samples (the fourth day of basal fertilization, tiller fertilization and panicle fertilization) were prepared for measurement of soil microbial enzyme activity including on a spectrophotometer (UV-2600, Shimadzu) according to the method, 23 and the specific details are presented in Text S3. † Statistical analysis SPSS 27.0 was used for statistical analyses based on one-way analysis of variance (ANOVA) (P < 0.05).…”

Effect of effluent from Nile tilapia fish ponds on soil quality, growth and shelf life of Amaranthus palmeri seedlings

“…Iron (305 mg/100g), calcium (397 mg/100g), vitamin A (8340mg/100g), and vitamin C (99mg/100 g) are all found in the leaves and succulent steam (Dunsin et al, 2016). Because of its short duration and high yield per unit area, it works well in crop rotations (Wang et al, 2022). Despite these bene ts, the vegetable is feared and expensive in the market due to the high cost of production (Anjorin et al, 2021).…”

“…Organic fertilizer (Fishpond e uent) has been successfully used to produce vegetables in the past (Ojobor and Tobih, 2015;Iren et al, 2016;Devi et al, 2017), but there is no information on the use of tilapia sh pond e uent on the initial germination, growth and shelf life of Amarathus palmeri seeds and on soil quality. Because its nutrients are released gradually, organic fertilizer can sustain continuous vegetable production (Prein, 2002;Muendo et al, 2014; Urra et al, 2019;Wang et al, 2022). It also has the potential to improve soil organic matter .…”

“…Quality soil is essential for long-term and continuous vegetable production (Kleber and Johnson, 2010; Kallenbach and Grandy, 2011). Amarathus palmeri is commonly referred to as "poor man's spinach," and it is one of the most affordable, widely accepted, and commercially grown leafy vegetables (Wang et al, 2022). It is primarily grown in Tamale and other regions in Ghana.…”
