“…Positive responses for the application of biosolids in pots and field conditions probably occurred because the material had a relatively high content of nutrients and organic matter (table 2), as also reported by Abreu et al (2017Abreu et al ( , 2019 and Sousa et al (2019). Another factor is the improvement of physical conditions in the pit, as reported by Guerrini et al (2017) and Balduino et al (2020), the organic material of the biosolid acts as a soil conditioner, having a direct influence on the results presented by the plants, as it improves the chemical quality (Caldeira Junior et al 2009) and the physical attributes, acting on the structure and state of aggregation particles, decreasing density and increasing aeration and moisture retention in the soil (Nobrega et al 2007). In addition, tree species in the Atlantic forest live in environments relatively rich in organic matter and normally respond to fertilization with organic materials.…”
