“…The most important variation was Zn, which was present at a high concentration in CSS (Table 2). Backes et al [41] found that increasing CSS rates from 0 to 48 Mg ha −1 on a Rhodic Hapludox, as was investigated in this study, but cultivated with zoysia grass (Zoysia japonica Steud. ), resulted in an increase in (bio)available Zn concentrations in soil.…”

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.

“…Plots that received syntetic fertilization (SF) showed a SCR of approximately 21%, 12%, 10% and 29% lower in comparison to the highest dose of applied sludge. Backes et al (2013), comparing a dose of 48 Mg ha -1 of sludge with a control (no fertilization), showed a lower SCR by 61% and 65% at 45 and 130 DAA, respectively.…”

“…The amount of time may not have been sufficient to release all nutrients. According to the nutrient evaluation conducted by Backes et al (2013), 67% of the N is released within a period of up to 120 days. Meanwhile, Godoy et al (2007) note the need for basic fertilization for shoot development to begin.…”

“…Backes et al (2009), in their study to verify non-composted sewage sludge doses in zoysia grass sod production, found that a single application of 40 Mg ha -1 produced the maximum coverage rate at 165 DAA. Meanwhile, in a different study, Backes et al (2013) evaluated the effects of composted sewage sludge on the production of zoysiagrass and found that a dose of 46.8 Mg ha -1 produced the maximum SCR only at 380 DAA. These results suggest that the addition of a carbon source during the sewage sludge composting process dilutes the nutrients in the sludge, thus requiring a higher dose to reach the maximum SCR.…”

This study evaluated whether the use of composted sewage sludge in zoysia grass sod production can partially or completely substitute fertilization based on urea. The experiment was conducted on a sod farm located in Itapetininga, São Paulo State, Brazil. The experimental design was a complete randomized block design with five replications and experimental plots of 5 m2 in a 2x6 factorial scheme. The first factor was the method of application (single or split), and the second factor was composted sewage sludge fertilization and two controls (no fertilization and a standard dose of conventional fertilizer). The conventional fertilizer (urea) dose corresponds to 300 kg N ha-1 and the sewage compost doses correspond to 100, 200, 300, and 400 kg N ha-1 . The experiment began with the liming of the total area at 60 days after the previous harvest of zoysia grass sod. Three methods were used to evaluate sod production: soil cover rate, green color intensity, and leaf analysis. At 212 days after the beginning of the experiment, the compost treatment of 30 Mg ha-1 (300 kg ha-1 of N), applied in a single dose, allowed for complete sod formation (100% soil cover rate).

-Nitrogen is the nutrient that provides the best grass growth responses, and proper nitrogen fertilization can enable the formation of sod in less time and firm enough to be handled after harvest. The aim of this study was to evaluate production and nutrient extraction of Emerald zoysiagrass (Zoysia japonica Steud.) according to the splitting of nitrogen doses. Treatments consisted of five doses (0, 150, 300, 450 and 600 kg ha -1 ) divided in three or six applications., The N dose of 400 kg ha -1 , divided in four applications, provided the formation of Emerald zoysiagrass sods six months after the previous sod harvest. Nutrient extraction by Emerald zoysiagrass occurs in the descending order, at kg ha -1 : N (207) > K (57) > (Ca) > S (27) > P (14) = Mg (14).Keywords -Turf, nitrogen fertilization, percent ground cover, Zoysia japonica Steud.Resumo -O nitrogênio é o nutriente que proporciona as maiores respostas no crescimento das gramas e a adubação nitrogenada adequada pode proporcionar a formação do tapete em menor tempo e firme para ser manuseado após a colheita. Objetivou-se com o trabalho avaliar a produção e a extração de nutrientes pelos tapetes da grama Esmeralda em função do parcelamento de doses de nitrogênio. O experimento foi realizado em fazenda de produção de grama, em Itapetininga, SP. Os tratamentos foram constituídos por cinco doses de N: 0, 150, 300, 450 e 600 kg ha -1 , divididos em três ou seis aplicações. A dose de 400 kg ha -1 N, parcelada em quatro aplicações, proporcionou a formação de tapetes de grama Esmeralda, seis meses após a colheita do tapete anterior. A extração de nutrientes pela grama esmeralda obedece a seguinte ordem decrescente, em kg ha -1 : N (207) > K (57) > Ca (45) > S (27) > P (14) = Mg (14).Palavras-chave -Gramado, adubação nitrogenada, taxa de cobertura do solo, Zoysia japonica Steud.
