- Extraction yield of humic substances from organic materials Irina Pedroso-Rodriguez Lourdes Yamén González-Sáez Jesús Luis-Orozco Liz Pérez-Martínez Carlo Vandecasteele Jo Van Caneghem Ingeniería Yield extraction humic substances organic solid waste At present there is a great advance in the use of organic substances as fertilizers; humic substances are one of them with various forms of extraction. This article evaluates the extraction yield of humic substances (humic acid and fulvic acid) from three raw materials and different basic extractants and acids. In the basic extraction of humic substances, the type of raw material significantly influences, to a p value equal to 5 %. The maximum extraction volumes of humic substances are with garden waste. The fractionation stage of the humic and fulvic acids (acid extraction) depends on the type of basic extractant. The alternative Vermicompost - NaOH - HCl is the most economic and technically feasible, with 38.53 % of extraction yield value of humic acid and 64.90 $/h of gross profit. 2022 artículo científico 0012-7353 https://www.redalyc.org/articulo.oa?id=49674890013 https://www.redalyc.org/journal/496/49674890013/ https://www.redalyc.org/journal/496/49674890013/html/ https://www.redalyc.org/journal/496/49674890013/49674890013.epub https://www.redalyc.org/journal/496/49674890013/movil 10.15446/dyna.v89n223.101666 en http://www.redalyc.org/revista.oa?id=496 Dyna application/pdf Universidad Nacional de Colombia Dyna (Colombia) Num.223 Vol.89
