“…The proportion of 30% OC (T3) was more suitable for the formulation of the substrates compared to the greater optimization of the inputs. However, studies point out that organic residues naturally present imbalance in nutrient concentrations (Boechat et al, 2020), thus, the diversification of the sources of these residues for a balanced production ISSN: 2525-8761 Brazilian Journal of Development, Curitiba, v.7, n.2, p.17984-18002 feb. 2021 of OC is paramount, and this should contain adequate amounts of nutrients for the production of seedlings of native species (Siles-Castellano et al, 2020, Marco et al, 2019).…”

Organic compost (OC) is a product of the decomposition of solid waste that can be used to correct the active acidity of the soil and also as a source of nutrients for plants. Thus, we sought to understand the influences of OC on soil pH during the incubation period, as well as its effects on the growth and development of the Acosmium nitens seedlings. The treatments consisted of natural soil (control) and three different dosages of organic compost (10, 30 and 50%). The effect of OC on soil pH was evaluated using a mixed design of repeated measurements, consisting of four treatments, six repetitions and four measurements during the study period. At 148 days after transplantation, the growth and development of Acosmium nitens seedlings were arranged in an completely randomized design, with four treatments and six repetitions, with the variables: total dry mass, dry aerial mass, dry root matter, diameter of lap, plant height, ratio of height/ diameter of lap and Dickson quality index. The OC significantly affected the active acidity of the soil, and caused significant interactions in the treatments during the incubation period of the substrate. The growth and development of plants were significant in relation to the dosages of OC in the substrate. Therefore, the OC from urban organic solid waste improved the degree of fertility and corrected the active acidity of the soil. The nutritional sufficiency for Acosmium nitens seedlings was achieved in the combination of 30% OC and 70% soil.
