“…Data related to the use of sewage sludge compost for the production of forest seedlings in containers, and pine seedlings in particular, are scarce. Bonnet et al (2002), working with three forest seedlings (Eucalyptus viminalis, Mimosa scarbrella and Schinus terebinthifolius) in 75 cm 3 containers, found that composted biosolids could be used satisfactorily in percentages of between 30 and 60%. However, the degree to which chemical fertilizer amounts could be reduced when the sewage sludge-based compost was used as a substrate component was not evaluated by the authors.…”

Two experiments were conducted to evaluate the effect of a sewage sludge-based compost (SSC) on the growth and mineral composition of containerized Pinus pinea L. seedlings. In the first experiment, five different substrates were tested: four binary mixtures of SSC and peat (100% SSC, 75% SSC, 50% SSC and 25% SSC, by volume) without fertilization, and a control substrate (peat-based substrate + fertilizer). Seedlings growing in the 100% SSC substrate showed the lowest growth, a consequence of both the low water availability and the high electrical conductivity that made SSC unsuitable to be the only component of a growing-media for pine ;seedlings'. The 50% SSC substrate presented physical and chemical properties similar to the control substrate and near the acceptable range for a growing-media. Moreover, no significant differences were found between growth of seedlings from treatment 50% SSC (without mineral fertilization) and seedlings from control treatment (with mineral fertilization). In the second experiment, a fertilization assay was performed with two substrates selected from the first experiment (50% SSC and control). The two substrates were fertilized with three levels of a macronutrient fertilizer (0.5, 1.0 and 2.0 g L( -1)) and two levels of a micronutrient fertilizer (0 and 0.4 g L(-1) of fertilizer containing only micronutrients). Results obtained suggest that replacing 50% (by volume) of peat-based substrate by the sewage sludge-based compost allowed: maintenance of the commercial value of seedlings; reduction of the amount of peat used in the substrate; a need for only half the amount of macronutrient fertilizer applied in the basal fertilization; and omission of micronutrient fertilization.

“…The SS's physical, chemical, and biological characteristics are decisive in indicating its use as a substrate or not. It is necessary to observe factors such as high density, low porosity, salinity, pH, pathogenic microorganisms, and potentially toxic substances 16 , 20 , 43 , 46 . These and other factors vary between SS from different WWTPs and even in different batches from the same plant 10 .…”

“…Evaluating the production of Schinus terebinthifolia seedlings, Bonnet et al (2002) observed that thermally dried SS could be applied in proportions of up to 15% of the substrate due to its high pH 46 . While for the composted sludge, the authors found it was possible to produce seedlings in a substrate with 100% SS, although proportions between 30 and 60% were recommended 46 . Kratz et al (2013) found that even in 10% of the substrate, the SS harmed Mimosa scabrella seedlings.…”

Schinus terebinthifolia Raddi is a species with several potential uses; selecting the proper substrate and fertilizer rate can be vital for seedling production in a nursery environment. This study aims to evaluate two substrates, namely: (i) sewage sludge (SS) from Ilha WWTP; (ii) a commercial substrate (CS) made of organic materials (mainly sphagnum peat). Increasing rates of controlled-release fertilizer – CRF (0, 3, 6, and 12 kg m−3) were applied. The experiment was completely randomized with a factorial 2 × 4 scheme (substrates × rates). The seedlings’ growth, biomass, and quality were evaluated. The treatments were compared by Tukey test and regression analysis, where linear, quadratic, and cubic models were considered. Principal components analysis (PCA) and cluster analysis were performed. The CRF rates showed non-significant effects for most of the investigated variables in the SS substrate. In the CS, a 7.8 kg m−3 rate of CRF showed the best growth performance. The multivariate analysis of the morphological parameters proved suitable as a complementary approach to evaluate the seedlings’ quality. Seedlings reached recommended values for height, diameter, and quality in the 100% SS substrate without chemical fertilizers; thus, Schinus terebinthifolia production in the SS from Ilha is recommended. Besides the growth advantage, the SS can promote nursery cost savings with commercial substrates and chemical fertilizers.

“…Observa-se que, para esta característica avaliada, o substrato que lodo do tratamento de esgoto não diferiu do substrato S2 (Tabela 3). Bonnet (2002) observou relação H/DC de 13,0 em mudas de Eucalyptus viminalis produzidas em substrato contendo 60 % de biossólido compostado combinado com 40 % de substrato comercial a base de casca de pinus e vermiculita e de 12,9 para o substrato comercial a base de casca de pinus, podendo ser encontrado valores diferentes para este parâmetro, com utilização de diferentes substratos, entre diferentes espécies vegetais de Myrtaceae.…”

O objetivo deste trabalho foi avaliar o efeito de diferentes substratos na produção e qualidade de mudas de Eugenia uniflora DC. Os tratamentos foram compostos por quatro substratos, sendo: S1) 100 % substrato comercial Plantmax®; S2) 50% substrato comercial Plantmax® + 50% substrato cama de equino; S3) 50% substrato comercial Plantmax® + 50% resíduo do tratamento de esgoto e S4) 50% substrato comercial Plantmax® + 50% resíduo do tratamento de água., sendo realizado análise de alguns parâmetros físico-químico dos substratos. Os tratamentos foram arranjados em delineamento inteiramente casualizado, com cinco repetições com 25 sementes cada. A cada três dias durante 90 dias foram realizadas a contagem de plântulas que emergiram para posterior calculo de índice de velocidade de emergência. Decorridos 180 dias após a semeadura foi calculada a porcentagem de emergência e as demais características biométricas, tais como: comprimento da parte aérea e do sistema radicular, diâmetro do coleto, número de folhas, massas fresca e seca da parte aérea, radicular e total e, ainda foi calculado o índice de qualidade de Dickson, bem como foi quantificado o teor de alguns macro e micronutrientes do sistema radicular, do caule e das folhas. Diante dos resultados obtidos foi observado que o substrato composto de resíduo do tratamento de água se mostrou efetivo a obtenção de mudas viáveis para plantio a campo.
