This study aimed to evaluate the effect of substrates made of composted sewage sludge and irrigation depths on the growth and quality of E. grandis x E. urophylla cuttings to optimize water management for each substrate. The substrates were obtained from sewage sludge composted with sugarcane bagasse or Eucalyptus bark, namely: composted sewage sludge with sugarcane bagasse (1:3 v:v); sewage sludge composted with Eucalyptus bark (1:3 v:v) and a mixture of both substrates in a volumetric proportion 2:1 (v:v). Commercial substrate composed of Sphagnum peat, vermiculite and rice husk (3:1:1 v:v: v) was used as a control. The irrigation depths tested were 11, 14 and 17 mm, applied in two daily applications. The substrates were physically and chemically characterized and height, stem diameter, shoot, root and total dry mass, Dickson quality index and root system conformation were measured to determine the growth and quality of seedlings. The substrates obtained through the composting of sewage sludge with sugarcane bagasse or Eucalyptus bark are fit for producing Eucalyptus cuttings, however, the water specificity of each substrate must be considered. Although an 11mm irrigation depth is indicted for the mixture of both substrates (2:1 v:v), a 17mm irrigation depth is needed for the sewage sludge composted with sugarcane bagasse (1:3 v:v) substrate.

A necessidade de soluções sustentáveis para as questões ambientais impulsiona o aproveitamento do lodo gerado no tratamento de esgoto. Uma das opções é seu uso como insumo agrícola e florestal. Dessa forma, os objetivos deste trabalho foram avaliar o uso de lodo de esgoto aeróbio compostado com podas de árvores trituradas para a produção de mudas de Pimenta pseudocaryophyllus (craveiro-do-mato) com diferentes níveis de fertilização e comparar seu crescimento com o do substrato comercial de casca de Pinus compostada e vermiculita. Três níveis de fertilizante de liberação lenta foram testados (0; 2,7 e 4 g.dm-3) em três tipos de substratos: comercial; composto à base de lodo na proporção 3:1 (v:v); e composto à base de lodo na proporção 2:1 (v:v). Para avaliação foram mensuradas as variáveis: altura e diâmetro. O crescimento proporcionado às mudas com o uso dos compostos de lodo de esgoto foi superior ao substrato comercial em todos os níveis de fertilização, ficando ainda mais evidente se comparado ao nível sem adição de fertilizante. Apesar de os maiores valores obtidos (estatisticamente significativos para altura) terem sido observados com o uso do composto à base de lodo 3:1 com adição de 4 g.dm-3 de fertilizante, os obtidos com o uso do composto 2:1 com 2,7 g.dm-3 de fertilização foram capazes de proporcionar um crescimento 73% superior em diâmetro de colo e 66% superior em altura em relação às mudas produzidas com o substrato comercial com o mesmo nível de fertilização, e ainda, com o uso do substrato 2:1 com a dose de 1,9 g.dm-3, pode-se obter ganhos para a altura de 66 para 72% superiores, resultando em menor consumo de fertilizante mineral e uso de maior proporção de lodo de esgoto.

Naturally infertile soils require large amounts of mineral fertilizers to obtain the desired crop yield. In the Cerrado region of Brazil, there is a need to investigate the potential of organic fertilizers to sustainably increase crop productivity and food security. A field study was conducted over two experimental seasons to evaluate the agronomic effectiveness of composted sewage sludge (CSS) as a fertilizer for soybean cultivation in infertile tropical soils. A 4 × 2 + 2 factorial randomized complete block design was applied with the following treatments: (i) CSS: 5.0, 7.5, 10.0, and 12.5 Mg ha−1 on a wet basis applied according to two different methods: whole area (WA) or between rows (BR); (ii) comparison with two alternative treatments: a control with no CSS and mineral fertilizer application, and an area treated with conventional fertilizers only. All the treatments were compared in terms of micronutrient concentrations in surface soil and plant leaves, plant development, crop productivity, and yield. Bi- (ANOVA, correlation matrix, and polynomial regression analysis) and multivariate (PCA, principal factor analysis) statistics were applied to determine statistical differences and relationships/observed variability among the treatments. Results showed that at higher CSS-WA rates: (i) soil and leaf micronutrient concentrations increased; (ii) there was an increase in soybean yield by 12 and 20%, respectively, as compared to control and conventional fertilization; (iii) soybean yield was 67% higher than the mean soybean yields for Brazil. Research outcomes confirm the benefits of CSS application on infertile agricultural soils in the Cerrado region, representing a strong alternative source of micronutrients in the CSS with respect to conventional fertilizers.
