Physicochemical Characteristics of Substrate Obtained Through Composting of Residues From Cotton and Poultry Industries / Características Físico-Químicas Do Substrato Obtido Através Da Compostagem De Resíduos Da Indústria Do Algodão E Da Avicultura

“…Note that if, except for S, the average content for the nutrients P, K, Ca and Mg were higher than the reference substrate. As observed by Silveira et al (2013), macro and micronutrients reduced with increasing carbon in the substrate composition except Fe and B (table 5).…”

“…According to the Normative Instruction n°13 of 24/03/2011 from the Brazilian legislation (Brasil, 2011), it is required that the inoculants should be capable of maintaining a minimum concentration of 10 8 viable cells per gram of the product for at least 180 days. Some materials with low cost, described as residues and with potential of use as inoculant carrier, such as sugarcane bagasse, rice husk, wheat bran, charcoal, wood shavings, mining waste, and others, have raised interest of some researchers (Schlemper & Sturmer, 2014;Czerniak & Sturmer, 2014;Silveira et al, 2013;Canellas et al, 2013). However, there are no studies of the usage of cottonseed hull and reports about the physicochemical characterization of composted substrate for inoculation purposes either.…”
