    Sugarcane demands large amounts of nutrients to reach a high level of productivity. Nutrients are generally supplied by mineral fertilizers, but their high costs and negative environmental impacts have generated interest in greater use of organic nutrient sources such as composted sewage sludge (CSS). In this study, we evaluated changes in soil chemical properties after the application of CSS or CSS/mineral fertilizer (MF) combinations to soil containing sugarcane seedlings under nursery conditions. Treatments included: T1: conventional mineral fertilization (MF) without application of CSS, T2: 100% of the recommended MF (06–30–24); T3: application of 2.5 Mg−1 CSS; T4: 5.0 Mg−1 CSS, T5: 7.5 Mg−1 CSS, T6: 2.5 Mg−1 CSS and 50% MF, T7: 5.0 Mg−1 CSS and 50% MF, T8: 7.5 Mg−1 CSS and 50% MF, T9: 2.5 Mg−1 CSS and 100% MF, T10: 5.0 Mg−1 CSS and 100% MF, T11: 7.5 Mg−1 CSS and 100% MF. Soil chemical properties were evaluated from the soil surface (0.0–0.25 m) and subsurface (0.25–0.50 m) horizons. The results showed that the increase in CSS application did not affect soil organic matter content at either depth, while Zn concentrations increased in the soil subsurface horizon. The application of CSS at 5.0 Mg ha−1 with or without 50% MF resulted in the highest pH values, sum of bases, cation-exchange capacity, P, K, Ca, Mg, Cu, and Zn in surface horizons. The use of CSS as an organic fertilizer in sugarcane nurseries improves soil fertility, reduces mineral fertilizer requirements, and, thus, facilitates the sustainable disposal of sewage sludge.

    Composted Sewage Sludge Application in a Sugarcane Seedling Nursery: Crop Nutritional Status, Productivity, and Technological Quality Implications

    by Rafael dos Santos Silva, Arshad Jalal, Raimunda Eliane Nascimento Do Nascimento, Nathércia Castro Elias, Karen Cossi Kawakami, Cassio Hamilton Abreu-Junior, Fernando Carvalho Oliveira, Arun Dilipkumar Jani, Zhenli He, Fengliang Zhao, et al.

    Composted sewage sludge (CSS) contains large amounts of organic matter and nutrients and can be used as an organic fertilizer to improve growth, yield, and quality of sugarcane. However, there is a lack of information regarding the impact of CSS application on sugarcane seedling performance in nursery environments. A field study was conducted using a randomized complete block design to evaluate the development, nutritional status, productivity, and technological quality of sugarcane seedlings after CSS application with or without mineral fertilizer. Morphological variables (stem height, diameter, and number, as well as leaf area), technological attributes (total recoverable sugar: ATR; quantity of sucrose in sugarcane juice: Pol; Brix: percentage (weight/weight) of soluble solids contained in juice; TAH: tons of sugar per hectare), nutritional status, and sugarcane productivity were evaluated. Treatments did not influence morphological and technological variables except for TAH but did positively alter nutritional status and seedling productivity. The application rates of 5.0 and 7.5 Mg ha−1 of CSS with or without mineral fertilizers (MF) provided the greatest increase in crop productivity. Our results indicate that CSS can be a sustainable nutritional management option in sugarcane seedling nurseries, resulting in greater crop productivity at lower mineral fertilization rates.

O experimento foi conduzido na Unidade de Pesquisa Hélio de Moraes, do IAC, no município de Jaú, SP, (22°17’ S 48°34’ O, em Latossolo Vermelho). A variedade de cana-de-açúcar foi a RB92579. O delineamento experimental foi em blocos casualizados, composto por fatorial de 2 manejos de irrigação: irrigado (I) e não irrigado (NI), 2 manejos de inoculação: com inoculação (Inoc) e sem inoculação (Não inoc) com bactérias diazotróficas (BDs); e com 4 níveis de disponibilidade de nitrogênio (0, 70, 140 e 210 kg ha-1 de N), compondo assim 16 tratamentos com 4 repetições. O experimento teve duração de 365 dias, quando então foram realizadas as análises tecnológicas e determinou-se a produtividade de colmos (TCH) e de açúcar (TPH). A cana-de-açúcar elevou sua produtividade com a elevação das doses de nitrogênio. Nos tratamentos irrigados essa elevação foi maior comparando-se com os tratamentos não irrigados. Palavras-chave: Saccharum spp.; gotejamento subsuperficial; adubação nitrogenada; fixação biológica do nitrogênio. DELLABIGLIA, W. J.; GAVA, G. J. C.; ARLANCH, A. B.; BOAS, R. L.

    Decomposição de palha de cana-de-açúcar recolhida em diferentes níveis após a colheita mecânica

    by Nilza Patrícia Ramos, Carina Sayuri Yamaguchi, Adriana Marlene Moreno Pires, Raffaella Rossetto, Rosana Aparecida Possenti, Ana Paula Packer, Osvaldo Machado Rodrigues Cabral, Cristiano Alberto de Andrade

    O objetivo deste trabalho foi determinar o efeito do recolhimento de quantidades variáveis da palha de cana-de-açúcar sobre sua decomposição na superfície do solo, após subsequentes socas. O experimento foi realizado por duas socas subsequentes, com a variedade de cana-de-açúcar RB-845210, tendo-se testado quatro quantidades remanescentes de palha após a colheita: 11,3, 8,5, 5,7 e 2,8 Mg ha-1. Foram avaliadas as taxas de decomposição de biomassa, carbono, nitrogênio, celulose, hemicelulose e lignina, bem como a relação C/N e a quantidade de C e N mineralizada a partir da palha. O recolhimento variável da palha da cana-de-açúcar não alterou as taxas de decomposição da biomassa nem a mineralização de carbono, hemicelulose, celulose e lignina, em uma mesma soca. O processo de decomposição da palha não se esgota, mesmo após duas socas, independentemente da quantidade inicial de resíduo sobre o solo. A relação C/N e a decomposição da lignina servem como indicadores para verificar diferenças nas taxas de decomposição entre os níveis de palha avaliados, enquanto a decomposição da hemicelulose e da celulose somente detecta alterações nessas taxas ao longo do tempo. Em termos absolutos, quanto menor a retirada da palha do campo, maior a quantidade de carbono e nitrogênio mineralizada, mesmo que não haja diferenças na taxa de decomposição.

    Effects of surface application of calcium-magnesium silicate and gypsum on soil fertility and sugarcane yield

    by Carlos Alexandre Costa Crusciol, Rodrigo Foltran, Otavio Bagiotto Rossato, James Mabry McCray, Raffaella Rossetto

    Lime application recommendations for amendment of soil acidity in sugarcane were developed with a burnt cane harvesting system in mind. Sugarcane is now harvested in most areas without burning, and lime application for amendment of soil acidity in this system in which the sugarcane crop residue remains on the ground has been carried out without a scientific basis. The aim of this study was to evaluate the changes in soil acidity and stalk and sugar yield with different rates of surface application of calcium, magnesium silicate, and gypsum in ratoon cane. The experiment was performed after the 3rd harvest of the variety SP 81-3250 in a commercial green sugarcane plantation of the São Luiz Sugar Mill (47º 25' 33" W; 21º 59' 46" S), located in Pirassununga, São Paulo, in southeast Brazil. A factorial arrangement of four Ca-Mg silicate rates (0, 850, 1700, and 3400 kg ha-1) and two gypsum rates (0 and 1700 kg ha-1) was used in the experiment. After 12 months, the experiment was harvested and technological measurements of stalk and sugar yield were made. After harvest, soil samples were taken at the depths of 0.00-0.05, 0.05-0.10, 0.10-0.20, 0.20-0.40, and 0.40-0.60 m in all plots, and the following determinations were made: soil pH in CaCl2, organic matter, P, S, K, Ca, Mg, H+Al, Al, Si, and base saturation. The results show that the application of gypsum reduced the exchangeable Al3+ content and Al saturation below 0.05 m, and increased the Ca2+ concentration in the whole profile, the Mg2+ content below 0.10 m, K+ below 0.4 m, and base saturation below 0.20 m. This contributed to the effect of surface application of silicate on amendment of soil acidity reaching deeper layers. From the results of this study, it may be concluded that the silicate rate recommended may be too low, since the greater rates used in this experiment showed greater reduction in soil acidity, higher levels of nutrients at greater depths and an increase in stalk and sugar yield.
