Aug 20, 2020 · Digestion duration for 30 days was recommended to reduce GHG emissions and increase compost quality, while digestion duration for 45 days was optimal for net energy production. However, the daily net energy of 45 day digestion was increased <18.1% compared with 30 day digestion.
y Composting livestock manure reduces many of the drawbacks associated with raw manure use. It’s also less likely to cause nutrient imbalances. The composted manure can safely be applied directly to growing vegetable crops.
Jan 14, 2022 · Previous studies reported that inoculation of microbes into the composting led to improved mineralization , accelerated the composting process of OPEFB from 64 days to 50 days and enhanced the compost maturity of rice straw and cattle manure by an increase in total nitrogen, phosphorus and potassium content .
Dec 15, 2023 · During the cattle manure/wheat straw aerobic composting, microorganisms showed the highest degradation capacity for polymers, especially typical aromatic hydrocarbons such as Tween 80, which could be attributed to the properties of microorganisms in the cattle gut and the production of specific heat-resistant enzymes by thermophilic fungi

Apr 10, 2023 · Several factors increase the costs of using manure as a commercial fertilizer replacement. First, manure has a low nutrient value-to-mass ratio. This is partly because of its water content, which can be up to 90 percent of the total weight. The low quantity of nutrients per ton makes manure application and transportation time-intensive and costly.
Apr 19, 2020 · At the same time, the yearly manure production of EU (at 27 member countries) is estimated at 1.4 billion tons . A detailed breakdown of manure between livestock (pigs, cattle, and chickens) and manure types (solid, liquid, slurry), for each Member State, is reported in Foged et al. .
Jan 1, 2023 · The most popular for the disposal of extensive manure waste are composting (i.e., converting organic wastes into biological fertilizers) [4], [25], [26], [27], anaerobic digestion (for bioenergy production) [28], thermochemical processes (for the production of high value-added products) [22], and other integrated-treatment pathways [29
The findings revealed that the use of compound microbial inoculants increased the compost temperature, accelerated moisture reduction, enhanced cellulase activity, and stimulated the accumulation of NH 4 +-N, NO 3--N, and total nitrogen (TN), resulting in a 9% increase in TN content. The abundance of Firmicutes decreased by 3.95% at the

They concluded that composting and applying livestock compost is more energy efficient than hauling raw manure. The decrease in volume and mass from composting reduced the hauling requirements enough to offset the energy required to compost. The energy ratio of raw manure to composted manure was 1.56-to-1 energy units.
