“…The initial increase in the soil pH by FYM in the present study can primarily be attributed to the high pH of FYM (7.7) at the time of its application. It may also partly be explained by proton (H + ) exchange between the soil and the added manure [18,19]. During the initial decomposition of manures, prior to their collection, some formation of phenolic, humic-like material may have occurred [16].…”

“…The reduction in exchangeable acidity can partially be attributed to an initial increase in soil pH that was observed with the OMs. Several other workers have measured an increase in soil pH with concomitant decrease in exchangeable Al during decomposition of organic residues in soils [16,18,24]. An increase in soil pH results in precipitation of exchangeable and soluble Al as insoluble Al hydroxides [25], thus reducing concentration of Al in soil solution.…”

We tested the effects of two organic materials (OMs) of varying chemical characteristics that is, farmyard manure (FYM) and Tithonia diversifolia (tithonia), when applied alone or in combination with three inorganic P sources, that is, triple superphosphate (TSP), Minjingu phosphate rock (MPR), and Busumbu phosphate rock (BPR) on soil pH, exchangeable acidity, exchangeable Al, and P availability in an incubation study. FYM and tithonia increased the soil pH and reduced the exchangeable acidity and Al in the short term, but the inorganic P sources did not significantly affect these parameters. The effectiveness of the inorganic P sources in increasing P availability followed the order, TSP > MPR > BPR, while among the OMs, FYM was more effective than tithonia. There was no evidence of synergism in terms of increased available P when organic and inorganic P sources were combined. The combination of OMs with inorganic P fertilizers may, however, have other benefits associated with integrated soil fertility management.

“…Among the main positive effects of waste compost application is the variation of chemical attributes in acid soils, such as increase in pH, neutralization of exchangeable acidity, reduction in potential acidity, increase in organic carbon content and in the availability of phosphorus, potassium, calcium, magnesium and increase in cationic exchange capacity (Kiehl 1985;Xin et al 1992;Wong et al 1998;Abreu Junior et al 2000;), which may represent improvement in the chemical, physical and biological properties of the substrate used that may positively affect seedling production.…”

The present study aimed to assess the behavior of seedlings of Schizolobium parahyba (Vell.) Blake growing on different substrates and irrigation levels, and to study the use of urban waste compost in substrates. The experiment was carried out in the College of Agricultural Sciences, Universidade Estadual Paulista (UNESP), Department of Agricultural Engineering, Jaboticabal Campus, state of São Paulo, Brazil. The experimental design used was completely randomized, consisting of 30 treatments in a factorial design with 15 substrates and two irrigation levels in four replicates. The substrates were composed of different materials: urban waste, Plantmax ® , dry cattle manure, vermiculite and soil. For the study of seedling growth, the following characteristics were evaluated: height (H), root-collar diameter (D), number of leaves, shoot dry weight, root dry weight, total dry weight, H/D ratio, Dickson's quality index, and the ratio between height and shoot dry weight (H/SDW). Assessments of the first three characteristics were carried out 20, 35, 50 and 65 days after sowing. Results showed that urban waste compost increased the growth of Schizolobium parahyba. There were significant differences for the irrigation levels tested; with better results for 150% ET compared to 100% ET irrigation level. Key words: urban waste compost, soil fertility, native species. ResumoEste trabalho teve como objetivo avaliar o comportamento de mudas de guapuruvu (Schizolobium parahyba (Vell.) Blake) crescidas em substratos constituídos por misturas de cinco materiais, em diferentes combinações, bem como analisar a influência da irrigação no crescimento das mudas em viveiro. O experimento foi instalado no Departamento de Engenharia Rural da Faculdade de Ciências Agrárias e Veterinárias -UNESP, Campus de Jaboticabal -SP, Brasil. O delineamento utilizado foi o inteiramente casualizado consistindo de 30 tratamentos num esquema fatorial 15 × 2 (15 substratos e 2 níveis de irrigação), em 4 repetições. Os substratos foram compostos por combinações de diferentes materiais: Composto de lixo urbano, Plantmax ® , esterco bovino curtido, vermiculita e solo. Para o estudo do crescimento das mudas, as seguintes características foram avaliadas: altura da parte aérea (H), o diâmetro do colo (D), o número de folhas, o peso da massa seca da parte aérea, do sistema radicular, e peso total, a relação H/D, o Índice de Qualidade de Dickson e a relação altura da parte aérea/ peso da massa seca da parte aérea. As três primeiras características foram medidas aos 20, 35, 50 e 65 dias após a semeadura. A análise dos resultados obtidos permitiu concluir que o composto de lixo urbano favoreceu o crescimento das mudas de Schizolobium parahyba. Quanto aos níveis de irrigação testados, pôde-se verificar que houve diferenças estatísticas e o nível de irrigação 150% ET se destacou em relação ao 100% ET. Palavras-chave: composto de lixo urbano, fertilidade do solo, espécies nativas.

“…El aumento de los valores de pH en suelos ácidos, cuando son sometidos a la aplicación de compuesto de residuo urbano, puede ser atribuido a: la aplicación de humus alcalinos (Kiehl 1985), la producción de hidroxilo (OH -), la acción del oxígeno de la solución del suelo que actúa como receptor de electrones provenientes de la oxidación microbiana del carbono (Mattiozzo-Prezotto 1992), y la capacidad de consumo de protones (H + ) (Wong et al 1998) y de H + + Al 3+ por la carga orgánica del compuesto (Oliveira 2000); también, indirectamente, al aumento en los tenores de cationes cambiables del suelo Ca 2+ , Mg 2+ , K + y Na + Cuadro 7. Resultado del análisis de varianza para las relaciones altura/diámetro de la base del tallo (H/D), altura/materia seca de la parte aérea (H/MSPA), materia seca de la parte aérea/materia seca de la raíz (MSPA/MSR) e índice de calidad de Dickson (IDC) para plántulas de Tabebuia heptaphylla en respuesta a diferentes sustratos y niveles de irrigación (100% y 150% ET) a los 150 DDS.…”

“…Tales mecanismos deben actuar simultáneamente para el aumento del pH en el suelo y parece ser que el principal de ellos es el cambio de H + entre el sistema tampón del suelo y de la materia orgá-nica del compuesto (Wong et al 1998, Oliveira 2000. Los antecedentes descritos permiten suponer que tales mecanismos también ocurren en los sustratos en cuya composición haya compuesto orgánico.…”

SUMMARYThe objective of this research was to evaluate the growth of Tabebuia heptaphylla seedlings in distinct substrates with different amounts of urban waste compost and the relation between this growth and irrigation. A completely randomized experimental design was used, with a factorial arrangement of 15 substrates and 2 irrigation levels. The substrates were composed by the combination of different materials: urban waste, tanned cattle manure, vermiculite, soil and the commercial form Plantmax®. For the study of the seedlings development, the following characteristics were evaluated: plant height, stem diameter at soil level, number of leaves, above ground dry matter, root system dry matter, relation between plant height and stem base diameter, Dickson quality index and relation between plant height and above ground dry matter. Evaluations of plant height, stem diameter at soil level and number of leaves were made at 75, 90, 105, 120, 135 and 150 days after sowing. According to the results, it was concluded that urban waste compost does not increase plant development. Significant differences in relation to the irrigation levels were found, with better results for the 150% irrigation level compared to 100% evapotranspiration.Key words: native forest species, urban solid waste, height of plants. RESUMENEl estudio tuvo como objetivo evaluar el comportamiento de plántulas de Tabebuia heptaphylla producidas en sustratos con incorporación de diferentes cantidades de residuos urbanos y con dos regímenes de riego. El diseño estadístico utilizado consistió en bloques aleatorizados con 30 tratamientos en un esquema factorial de 15 x 2 (15 sustratos y dos niveles de irrigación), con dos repeticiones. Los sustratos fueron constituidos de diferentes combinaciones de: compuesto de residuo urbano, estiércol curtido, vermiculita más suelo, y sustrato comercial Plantmax ® . Para el análisis de crecimiento de las plántulas se consideró: altura de la parte aérea, diámetro de la base del tallo de la planta, número de hojas, materia seca de la parte aérea y sistema radicular, relación altura de la parte aérea/diámetro de la base del tallo, índice de calidad de Dickson y relación altura de la parte aérea/materia seca de la parte aérea. Las características evaluadas fueron medidas a los 75, 90, 105, 120, 135 y 150 días después de la siembra. Se concluye que el compuesto de residuo urbano no favoreció el crecimiento de las plantas. El crecimiento de las plantas fue superior con el nivel de irrigación de 150% de la evapotranspiración con respecto al de 100%.Palabras clave: especies forestal autóctona, compuesto de residuos urbanos, altura de plantas.
