“…The greater MB-C content in the soil may also be a result of the more recalcitrant forms of C in the deep pig litter than in the pig slurry (Giacomini & Aita, 2008), which is easily decomposable and, therefore, has slower mineralization and, consequently, lower increase in the solution or even in the microbial biomass (Gessner et al, 2010). Furthermore, the carbon increase of the microbial biomass in the PS180 treatment may be associated with the application of the manure in the soil, which contained, in average, 30, 8, and 27 kg ha -1 N, P and K, respectively, and was carried out 15 days before soil collection.…”

-The objective of this work was to evaluate the microbiological and chemical attributes of a soil with a seven-year history of urea and swine manure application. In the period from October 2008 to October 2009, soil samples were collected in the 0-10 cm layer and were subjected to the treatments: control, without application of urea or manure; and with the application of urea, pig slurry, and deep pig litter in two doses, in order to supply one or two times the recommended N doses for the maize (Zea mays)/black oat (Avena strigosa) crop succession. The carbon of the microbial biomass (MB-C) and the basal respiration (C-CO 2 ) were analyzed, and the metabolic (qCO 2 ) and microbial quotient (qmic) were calculated with the obtained data. Organic matter, pH in water, available P and K, and exchangeable Ca and Mg were also determined. The application of twice the dose of deep pig litter increases the MB-C and C-CO 2 values. The qmic and qCO 2 are little affected by the application of swine manure. The application of twice the dose of deep pig litter increases the values of pH in water and the contents of available P and of exchangeable Ca and Mg in the soil.

“…SOUSA et al (2014) observaram DBO inicial de 6240 mg L -1 em dejetos líquidos de suínos em lagoas de estabilização que, após 120 dias, pode ser reduzida para 516 mg L -1 . A aplicação de dejetos como fonte de nutrientes para plantas cultivadas tem sido muito estudada, apresentando bons resultados (ASSMANN et al, 2007;BARNABÉ et al, 2007;MEDEIROS et al, 2007;GIACOMINI & AITA, 2008), sendo que essa prática vem ao encontro da atual necessidade de sustentabilidade ambiental e conservação dos recursos naturais.…”

RESUMO:O objetivo deste trabalho foi avaliar as características bromatológicas de uma pastagem de Brachiaria decumbens fertilizada com dejetos suínos, bem como avaliar as alterações que a utilização desse dejeto causa em alguns atributos químicos do solo. O delineamento foi em blocos casualizados, com seis tratamentos: T1: ausência de adubação mineral e orgânica (tratamento--controle); T2 apenas com adubação mineral; T3, T4 e T5 com diferentes doses de dejetos líquidos de suínos (respectivamente ao equivalente a 60; 120 e 180 m 3 por hectare), e T6 tratamento organomineral (120 m 3 por hectare) de dejetos líquidos de suínos, com adição de fertilizante mineral). Observou-se que houve incremento em produtividade de massa seca (MS). O uso de dejetos de suínos resultou em aumento significativo nos valores de proteína bruta das plantas de Brachiaria decumbens, não tendo a mesma eficiência para os valores de fibra em detergente neutro (FDN), fibra em detergente ácido (FDA) e lignina. A aplicação de dejetos suínos aumentou os teores de N, P, Ca e Mg nas plantas de Brachiaria decumbens. Não foram constatadas alterações quando comparados os valores de pH e matéria orgânica do solo. Os dejetos líquidos de suínos podem ser utilizados para fornecer macronutrientes para as forrageiras, desde que com aplicação controlada. PALAVRAS-CHAVE:atributos do solo, fertilização de pastagem, resíduos orgânicos, suinocultura. FERTILIZATION WITH SWINE WASTE MANURE : THE INFLUENCE OF CHEMICAL CHARACTERISTICS IN Brachiaria decumbens AND CHANGES IN THE SOILABSTRACT: The objective of this study was to evaluate the qualitative characteristics of Brachiaria decumbens pastures fertilized with swine manure, as well as evaluating the changes that the utilization of manure causes in some soil chemical properties. The design was randomized blocks with six treatments: T1: absence of mineral and organic fertilizer (control ), T2 : with mineral fertilizer only, T3, T4 and T5 with different doses of swine slurry (respectively equivalent to 60 , 120 and 180 m 3 ha -1 ), T6 organic and mineral mixed treatment (120 m 3 per hectare) of swine slurry added with mineral fertilizer). It was observed that there was an increase in productivity dry matter (DM). The use of swine manure resulted in significant increase in crude protein values of Brachiaria decumbens plants, do not having the same efficiency for Neutral detergent Fiber (NDF), Acid detergent Fiber (ADF) and lignin. The application of manure increased the content of N, P, Ca, Mg in Brachiaria decumbens plants. No changes were observed when comparing the values of pH and soil organic matter. Liquid swine manure can be used to provide macronutrients for the fodder, since with controlled application.

“…Evaluating the potential N supply from pig slurry and deep-litter manure in maize, Giacomini & Aita (2008) concluded that although the application of deep-litter pig manure increased maize grain yield, when compared to non-fertilization treatments, pig slurry has immediate effects similar to the application of urea as a nitrogen source. This is explained by the fact that pig slurry has a low dry matter and high ammoniacal nitrogen content (40-70 % total N), while the manure in solid form has a high dry matter and high N content in organic form (70-90 % total N) (Giacomini et al 2013).…”

With the intensification of pig farming systems, in Brazil, the production of swine waste has increased considerably, leading to water and soil contamination, due to its improper release. Pig slurry composting is an alternative that can be used in order to avoid or reduce negative impacts, especially for producers with physically limited farm areas, or those who intend to increase the number of animals in their production units. This study aimed at evaluating the influence of pig slurry compost doses on the agronomic characteristics and grain yield of proso millet. A randomized blocks design experiment was installed with four replications and five treatments: control without fertilization, control with mineral fertilizer (NPK) and pig slurry compost doses (4.0 Mg ha-1, 8.0 Mg ha-1; 12.0 Mg ha-1). The pig slurry composting increased the dry matter yield, number of grains per plant and grain yield of proso millet, when compared to the control with or without mineral fertilizer. The proso millet yield, at the doses of 8.0 Mg ha-1 and 12.0 Mg ha-1 of pig slurry, was superior than for both the control without fertilization and the control with the recommended mineral fertilizer, with the latter reaching a maximum agronomic efficiency at the dose of 8.0 Mg ha-1.
