Manure biostabilization by effective microorganisms as a way to improve its agronomic value

Abstract

The traditional logic behind effective microorganism is based on a media inoculation with mixed cultures of beneficial microorganisms to create a more favorable environment for plant growth and health when the media is the soil. Following this rationale, other research works have been focused on studying the effect of effective microorganisms when they are used as manure stabilizing agents, in some cases by including them in animal diets, reporting, in all cases, beneficial properties. However, the use of effective microorganisms is not yet widespread. One reason may be that no rigorous research has so far been done on the actual utility of these mixed cultures on manure stabilization and crop production. In this work, the potential uses of effective microorganisms are shown with the focus on evaluating the influence of these mixed cultures on the biostabilization of manure before its use as fertilizer. This work also presents some new perspectives on the role and application of effective microorganisms as microbial inoculants to achieve a microbiological balance of manure so that it can improve its quality, increasing production and protection of crops when applied as fertilizer, helping to conserving natural resources and creating a more sustainable agriculture and environment. Finally, this document also reviews strategies on how to improve the effect of effective microorganisms after their inoculation into the soil as part of the manure.

Application of Lactic Acid Bacteria (LAB) in Sustainable Agriculture: Advantages and Limitations

“…Therefore, the molecular taxonomy and genome sequencing of LAB strains become an effective method for identifying species levels. Lactobacillus plantarum , L. casei , Lactococcus , Bifidobacterium , and Streptococcus lactis are isolated from the intestinal tract of animals and fermented food [ 22 ]. L. acetotolerans , L. pontis , and L. suebicus species show high survival rates in the cow gut [ 23 ].…”

“…In this context, farmyard manure and plant-based compost is integral to organic farming and sustainable agriculture. LAB decompose and bio-stabilize the animal and plant waste to improve the agronomic value and assimilate organic matter such as lignin and cellulose materials [ 22 ]. Wang et al, found that Bacillus stearothermophilus elevate the relative abundance of LAB strains in soil [ 122 ].…”

Analysis of the potential of effective microorganisms in plant production

“…to meet the nutritional needs of plants and to reduce the proportion of disease-causing microorganisms. In addition to metabolizing organic compounds, EMs produce simple plant compounds that, when added to the soil, improve their use in agriculture and stabilise the natural ecosystem (Hidalgo et al, 2022;Rastogi et al, 2020).…”

Effects of Feed-Through Sulfur on Growth Performance, Atmospheric Ammonia Levels, and Footpad Lesions in Broilers Raised Beginning with Built-Up Litter

“…This effect on ammonia is presumably caused by ammonia adsorption by the aluminosilicates as well as adsorption by carboxyl compounds, phenols, and lactones present on the biochar surface, in addition to changes in the gut microbiome due to biochar supplementation [ 19 , 20 ]. Another approach to ammonia control is to utilize effective microorganisms either as feed additives or additives to the environment, such as bacteria from the nitrogen-fixing genera Rhizobium , Azotobacter, Azospirillum, Beijerinckia, Azoarcus, Burkholderia, Enterobacter, Klebsiella, and Bacillus [ 21 , 22 , 23 ].…”
