Increased quality of small-scale organic compost with the addition of efficient microorganisms

Abstract

Substantial quantities solid waste from livestock are potential sources of nutrients for agroecological production on small-scale farms. The processes used to extract these wastes, however, must be capable of eliminating pathogenic microorganisms. We aimed to evaluate composting and vermicomposting processes by inoculating efficient microorganisms at the field scale. We used cattle and sheep manure with the inoculation of efficient microorganisms (EMs) at concentrations of 0, 2, and 4 mL L-1. In vermicomposting experiments, we added Lumbricus rubellus. After the maturation and stabilization phases of the compounds, concentrations of macronutrients, micronutrients, heavy metals, thermotolerant coliforms and Salmonella spp. were measured. We found that composting processes allowed high availability of macronutrients. Vermicomposting, associated with inoculation with 2 mL L-1 EMs, promoted the lowest concentration of thermotolerant coliforms, ensuring greater elimination of pathogens. The compost produced allowed the valuation of waste and use it as a quality organic fertilizer for agroecological production.

Pengaruh Konsentrasi Bioaktivator Effective Microorganism 4 terhadap Waktu Penyerapan Air, Massa, dan Kualitas Kompos Pada Lubang Biopori

“…Ada sekitar 80 jenis bakteri fermentasi yang terkandung di dalam EM4 (Meriatna et al, 2019). Pada penelitian yang dilakukan oleh Panisson et al (2021) menunjukkan bahwa penambahan EM4 dalam pengomposan disukai oleh mikroorganisme sebagai makronutrien dalam tahap kompos akhir, sehingga kompos memiliki nilai yang meningkat dan menghasilkan produk yang berkualitas. Proses pengomposan yang lama tidak efisien waktu sehingga hasil dari kompos tidak dapat segera digunakan (Hija et al, 2021).…”

Analysis of the potential of effective microorganisms in plant production

“…The deterioration of the natural environment contributes to the search for new, effective biological agents with a broad spectrum of activity. Microbiological preparations, which include properly selected, beneficial microorganisms that commonly occur in the natural environment, are highly effective (Panisson et al, 2021). In this aspect, liquid microbiological preparation Effective Microorganisms is gaining more and more popularity in Poland and in the world (Japan, Western Europe, USA, Brazil).…”

The Effect of Using Effective Microorganisms on the Changes in the Chemical Composition of Spring Wheat

“…In literature one can find a number of pieces of information about the positive effect of Effective Microorganisms on the volume and quality of crop yield. The use of Effective Microorganisms in crop cultivation improves seed germination, increases the efficiency of the photosynthetic process, improves the activity of enzymes as well as reduces the occurrence of diseases and pathogens [Domenico, 2019;Joshi et al, 2014;Panisson at al., 2021]. The plants treated with EM will have increased biomass and greater resistance to external factors and attack by pathogens.…”
