“…A reduction of the amounts of water-stable aggregates retained on the sieve of 8.00-4.76 mm for UWC rates above 50 m 3 ha -1 (second year of assessment) was also observed with application of high rates of other organic sources, such as alkaline residues from the pulp and paper industry (Medeiros et al, 2009), pig slurry (Arruda et al, 2010), vinasse from sugarcane (Passarin et al, 2007), and turkey litter (Costa et al, 2008;Pinto et al,. 2012).…”

“…Matos et al (2008) observed increases in SOC contents over time with the use of organic fertilizer (common bean and soybean straw + cattle manure). However, Pinto et al (2012) found that the soil carbon stock of an Oxisol varied in a quadratic manner in relation to the increased application of waste from turkey litter. Moreover, Arruda et al (2010) observed that SOC contents were not influenced by the addition of pig slurry.…”

SUMMARYThe use of urban waste compost as nutrient source in agriculture has been a subject of investigation in Brazil and elsewhere, although the effects on soil physical and chemical properties and processes are still poorly known. The aim of this study was to evaluate the effect of application of urban waste compost and mineral fertilizer on soil aggregate stability and organic carbon and total nitrogen content of a Rhodic Hapludox under no-tillage in the northwestern region of Rio Grande do Sul, Brazil, in the 2009/2010 and 2010/2011 growing seasons. The experiment was arranged in a 2 × 6 (seasons and fertilization) factorial in a randomized complete block design with four replications. The factor time consisted of two growing seasons (sunflower in 2009/10 and maize in 2010/11) and the factor fertilization of five rates of urban waste compost (0, 25, 50, 75 and 100 m 3 ha -1 ), and mineral fertilizer. Soil samples were collected from the 0.0-0.10 m layer to determine aggregate stability (mean weight and geometric diameter), soil organic carbon (SOC) and total nitrogen (TN). Rates of up to 75 m 3 ha -1 of urban waste compost, after two years of application to no-tillage maize and sunflower, improved aggregation compared to mineral fertilization in a Rhodic Hapludox. After the second crop, the SOC and TN contents increased linearly with the levels of urban waste compost.Index terms: soil organic carbon, aggregate stability, total nitrogen, soil structure, organic manure.( A utilização de composto de lixo urbano como fonte de nutrientes para a agricultura vem sendo investigada; entretanto, as alterações físicas do solo ainda são pouco conhecidas. Objetivouse avaliar a influência do uso de composto de lixo urbano e da adubação mineral na estabilidade de agregados e nos teores de carbono orgânico e nitrogênio total de um Latossolo Vermelho, em sistema plantio direto na região noroeste do Rio Grande do Sul. Utilizou-se o delineamento de blocos ao acaso, em esquema fatorial 6 × 2 (adubação e épocas), com quatro repetições. O fator épocas de avaliação constituiu-se dos anos agrícolas de 2009/10 (girassol) e 2010/11 (milho). O fator adubação foi composto por cinco doses de composto de lixo urbano (0, 25, 50, 75 e 100 m 3 ha -1 ), além de um tratamento adicional com fertilização mineral. Na camada de 0,0-0,10 m, foram determinados a estabilidade de agregados (diâmetro médio geométrico e ponderado), os teores de carbono orgânico (CO) e o nitrogênio total (NT). A utilização de doses crescentes de composto de lixo urbano favoreceu melhorias na agregação do solo, em relação à fertilização mineral. A utilização de até 75 m 3 ha -1 de composto de lixo urbano, após dois anos de aplicações em cultivos agrícolas com milho e girassol em um Latossolo Vermelho, sob sistema plantio direto, promoveu melhorias na agregação do solo, quando comparada à fertilização mineral. O teor de CO e o de NT, após o segundo cultivo, apresentaram incrementos lineares, em relação às doses de composto de lixo urbano.Termos de indexação: carbono orgâ...

“…The residual increase of potassium, by the poultry litter use, can be related to the concentrations of this nutrient, 1.9 and 14.2 times higher in relation to the farmyard manure and biochar, respectively (Table 1). Pinto et al (2012) also found increments of potassium levels into soil, through sequential application of turkey litter in a rotational grazing system in the Brazilian Savanna.…”

“…In spite of the lower contribution of nutrients per volume, organic amendments, such as bovine manure and poultry litter might even be superior to the mineral fertilizers, improving the biological, physical and chemical attributes of the soil (Bhattacharyya et al, 2010). Evaluating the effects of several applications of organic wastes, such as the turkey litter, over the years, Pinto et al (2012) found improving on soil fertility, increasing the pH, N, P, K, and base saturation rates, as well as organic carbon, and decreasing aluminum saturation.…”

The use of organic wastes, as an alternative to inorganic fertilizer, can be an important strategy for Brazilian agriculture. The objective was to evaluate the residual effects and the agronomic efficiency of organic amendments use on chemical attributes of a Haplic Cambisol and to soybean crop. A field experiment was carried out in a completely randomized split-plot design with three replications in Minas Gerais, Brazil, 2008/09. In the plots, the sources of organic amendments were evaluated (poultry litter, farmyard manure, and biochar) using three application rates (3, 6 and 9 Mg ha -1 ) into the subplots, and control treatment without amendments. Agronomic efficiency of the wastes linearly increased with the doses, independent of the organic source. Poultry litter, a nutrient-rich organic amendment, increased the soybean grain yield. The biochar use boosted the availability of calcium and magnesium levels in the soil, and a consequent increase in the sum of bases, base saturation, pH and effective cation exchange capacity of the soil. The poultry litter utilization enhances the soil acidity and availability of potassium, sulfur and zinc, over the time. The use of organic amendments increases the levels of phosphorus, potassium and zinc in the soil, after soybean cropping.Key words: agronomic efficiency index, Glycine max, organic amendments, sustainability Pó de carvão, esterco de curral e cama de frango no cultivo da soja e atributos químicos de um Cambissolo distrófico RESUMO A utilização de resíduos orgânicos, como alternativa ao uso de fertilizantes minerais inorgânicos, pode representar uma importante estratégia para a agricultura brasileira. Objetivou-se, nesse trabalho, avaliar a eficiência agronômica e os efeitos residuais da utilização dos resíduos orgânicos, cama de frango, esterco de curral e pó de carvão nos atributos químicos de um Cambissolo Háplico cultivado convencionalmente com a cultura da soja. O experimento de campo foi realizado em esquema de parcelas subdivididas, utilizando o delineamento em blocos casualizados com três repetições. Nas parcelas foram avaliadas as fontes dos resíduos orgânicos e, nas subparcelas, as doses dos resíduos (3, 6 e 9 Mg ha -1 ), mais o tratamento controle sem resíduos, na safra 2008/09, em Itutinga, MG, Brasil. Verificou-se que a eficiência agronômica dos resíduos aumentou com a elevação das doses, independente da fonte utilizada. A cama de frango, um resíduo orgânico rico em nutrientes, apresentou eficiência agronômica para elevar a produção de grãos de soja, sendo este resíduo orgânico mais eficiente agronomicamente que esterco de curral e pó de carvão. O uso do pó de carvão proporciona aumentos nos níveis de cálcio e magnésio do solo, com consequente elevação da soma de bases, saturação por base, pH e CTC efetiva do solo. Por sua vez, a utilização de cama de frango eleva a acidez e a disponibilidade de potássio, enxofre e zinco no solo, em curto prazo. Em geral, a aplicação de resíduos orgânicos proporciona incrementos nos níveis residuais de fósfo...

Purpose Due to the pressures of conforming to environmental quality standards and the increased costs of mineral fertilizer importation, there is growing interest in the use of organic residues as fertilizers. To test the hypothesis that indicates the quantity of animal manure (AM) depends on the phosphorus (P) needs of the crops, an experiment was run using three organic animal manures (chicken-CM, turkey-TM, and cow manure-CoM), enriched with limestone, gypsum, and phosphorus. Methods A greenhouse experiment was run using AM incorporated in a clayey soil, at a rate that equates to the P needs of Brachiaria sp. Contents of phosphorus, potassium (K + ), calcium (Ca +2 ), magnesium (Mg +2 ), sodium (Na + ), organic matter (OM), and values of pH and cation exchange capacity (CEC) were monitored during 120 days. Plants were collected to determine the dry matter.
