Abstract: | The recycling of organic wastes from biological fermentation processes for agricultural production is a fast development of bioconversion strategy. Microbes play a major role on physiochemical changes during Organic Liquid Fertilizer (OLF) preparation. Hence, this study investigated the Physiochemical changes such as pH, EC,TDS , nutrient availability and microbial count..The OLF was produced prepared compost, banana peels, wild sunflower leaves, and goat manure at the rates of 80g:50g:80g:80g (w/w) respectively. Also, brown sugar (25g/l of water) was added as a fermenting agent. The anaerobic fermentation was allowed up to 30 days. The results significantly (P<0.05) showed that, maximum EC (9.93 dS/m), TDS (6200 mg/L), lower pH (4.6), higher total nitrogen (513.4 mg/L), and total phosphorous (588.19 mg/L) at 15 DAF than at 30 DAF. Anyhow, significantly higher total potassium (6.42 mg/L) was reported at 30 DAF than at 15 DAF. Further, the increased number of microbes did not significantly influence on physiochemical changes of OLF, but s bacteria (14.09±0.3), Actinomycets (16.1±0.2) and fungus count (11±0.3) were significantly increased at 30DAF. It is concluded that except for potassium level, parameters such as EC, pH, TDS, N, P and microbial performance were highly recorded at 15DAF. Hence, a short fermentation time period (15 Days) would be recommended to achieve the best physiochemical parameters during the OLF preparation. |
