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.
