“…Although the efficiency of alternative substrates has been largely evaluated in nursery conditions (Kratz et al, 2012(Kratz et al, , 2013Kratz & Wendling, 2016;Stuepp et al, 2016;Gabira et al, 2020;Manca et al, 2020), their influence on increasing the growth of forest species in the field has not (Stuepp et al, 2016), generating a gap in substrate recommendation for commercial plantations. The challenge, in this case, has been to produce quality seedlings at a reduced cost (Kratz & Wendling, 2016;Kratz et al, 2017), seeking a better performance in the field, with reduced mortality and weed competition.…”

The objective of this work was to evaluate the survival and initial growth, in the field, of eucalyptus seedlings produced in different substrates. Eucalyptus benthamii seedlings produced in 36 substrates were evaluated in the field. The substrates consisted of mixtures, at different volumetric proportions, of: carbonized rice husk, charcoal with granulometry between 1.0-3.0 mm, charcoal with granulometry between 3.0-5.0 mm, coconut fiber, semi-decomposed pine bark, fine vermiculite, sewage sludge, and peat moss. At 1, 2, 3, 6, 12, 18, and 24 months after planting, survival, height, and diameter were determined. At 24 months after planting, height increment, diameter increment, transversal area, and basal area were also measured. The seedlings that showed 100% survival after 24 months under field conditions were those grown in the nursery in substrates with a higher proportion of fine vermiculite, sewage sludge, and peat moss, that is, in substrates with a higher microporosity. However, there is no effect of substrate characteristics on seedling initial growth in the field. A significant correlation is observed between the survival of seedlings at 6 months and their diameter at the end of the nursery period, evidencing the importance of this characteristic for the establishment of the plant in the field, regardless of the used substrate.

“…Regardless of irrigation depths, SEB provided seedlings with the largest amount of dry mass, although seedlings produced using 6 mm irrigation depth presented lower values than seedlings produced in SCB. Other studies using sugarcane bagasse and sewage sludge as substrate obtained better morphological characteristics of Eucalyptus and Peltophorum dubium seedlings growing under adequate irrigation depths (Gabira et al 2020a, Manca et al 2020, Silva et al 2020a). The lower total porosity values of SEB may have hindered the growth of the root system of seedlings under a low irrigation depth, making it difficult for water to go beyond the superficial region of the tube.…”

“…Because of its origin, sewage sludge presents a variability in composition, preventing its use at a commercial level based on the actual knowledge on the performance of the product (Nascimento et al 2020). Nevertheless, the use of sewage sludge reduces the acquisition of commercial substrates and chemical fertilizers, representing a sustainable alternative to landfill disposal (Manca et al 2020). Research using sewage sludge on seedling production focuses mainly on substrate characteristics and plant morphological responses, but the relationships between these substrates and other production factors on plant growth and gas exchange are still lacking.…”

The production of forest seedlings with adequate morphological and physiological characteristics is essential for the success of plantations. Substrates and irrigation are the major factors determining seedlings' growth. Substrates made of urban and agricultural residues are a sustainable alternative to peatbased substrates. In this study, we evaluated how composted sewage sludge substrates affect the growth and gas exchange in seedlings of Cedrela fissilis Vell. Seedlings were produced under daily irrigation depths of 6, 9, and 12 mm, and on different substrates. The substrates were based on sewage sludge composted with Eucalyptus bark or sugarcane bagasse, and a commercial substrate based on peat, involving a double factorial design with 12 treatments (3 irrigation depths × 3 substrates). Both physical and chemical characteristics of substrates were analyzed, and morphological traits and gas exchanges of seedlings were measured. Sewage sludge-based substrates presented different characteristics according to the material it was mixed. Eucalyptus bark provided higher bulk density (0.19 g cm -3 ) and lower total porosity (75%) to the substrate, while sugarcane bagasse increased macroporosity up to 60%. Seedlings produced in sewage sludge-based substrates presented a height up to 17.8 cm and stem diameters of between 8.39-10.29 mm. Higher shoot and root dry mass was obtained in sewage sludge-based substrates with irrigation depth of 9 mm, which were 3.71 and 2.01 g, respectively. Photosynthetic carbon assimilation varied between 2.26 and 3.23 µmol CO2 m -2 s -1 , and water use efficiency varied from 2.058 to 3.395 µmol CO2 (mol H2O) -1 , with the highest values being obtained in seedlings produced in sewage sludge-based substrates with irrigation depth of 6 mm. Our results demonstrate that sewage sludgebased substrates are an efficient alternative to commercial peat-based substrates for seedling production.

“…Similarly, the Ca content in the shoots and roots was strongly influenced by the high content of this element in the compost, which acted as the main source of Ca for cultivation. According to Manca et al [53], organic compost may have a high concentration of Ca and increase its availability in the soil as well as its content in leaves and roots. However, the excess sodium contained in the compost may have caused salt stress in the plant, generating a physiological response to reduce nutrient absorption [54].…”

Organic materials, such as biochar and organic compost, can reduce P sorption mechanisms and improve soil fertility, benefiting the reclamation of areas impacted by mining. This study evaluated how the chemical properties of Fe mining soil, the adsorption of P onto this substrate, and the growth of the native plant Dioclea apurensis, were affected by the application of açaí biochar (BC), organic compost (OC), and different P doses. Substrate collected from mining soil piles was incubated for 30 days with BC or OC. Each mining substrate with or without the addition of BC or OC received five doses of P (0, 40, 80, 120, and 240 mg∙kg−1 P). The addition of BC or OC promoted an increase in pH and nutrient availability (P, K, Ca, and B) in Fe mining soil. However, plants grown in the unamended mining soil (W) showed higher growth. The maximum P adsorption capacity decreased as a function of the addition of BC. We conclude that the application of BC reduced P sorption, while the application of either OC or BC altered the chemical properties of the soil and caused contrasting effects on P dynamics in Fe mining soil, and these treatments also affected plant growth.
