“…Os valores médios de C da biomassa microbiana (C microbiano) variaram de 37,3 a 92,8 mg C-CO 2 kg -1 (Figura 2a) e, embora esses sejam menores do que os normalmente registrados na literatura (Gatiboni et al, 2011;Kheyrodin et al, 2012;Balota et al, 2014), estão de acordo com os mencionados em estudos no Brasil (Lopes et al, 2010;Couto et al, 2013). Na análise do C microbiano para o solo coletado, não foram registradas diferenças significativas entre as áreas estudadas, dentro de cada época de coleta (agosto e novembro) (Figura 2a).…”

“…Esses resultados estão de acordo com as informações da literatura, pois os teores de C microbiano podem apresentar efeito positivo resultante da adição de dejetos de suínos (Balota et al, 2014) ou não (Kheyrodin et al, 2012;Couto et al, 2013), sendo esse resultado dependente da época (Carvalho et al, 2012;Couto et al, 2013) e da profundidade de coleta (Kheyrodin et al, 2012).…”

“…O quociente metabólico (qCO 2 ) foi obtido dividindo-se a respiração microbiana do solo pelo C da biomassa microbiana (Balota et al, 2014), e os resultados foram expressos em μg C-CO 2 g -1 .…”

“…Dentre os principais indicadores microbiológicos utilizados para avaliar a qualidade do solo, destacam-se a determinação do C da biomassa, respiração microbiana e atividade enzimática do solo (Araújo et al, 2012;Kheyrodin et al, 2012;Balota et al, 2014). A biomassa microbiana é um indicador sensível a mudanças no ecossistema, pois representa o destino inicial do C em transformação, e é uma das principais fontes de produção do CO 2 e das enzimas do solo (Moreira e Siqueira, 2006).…”

RESUMO O uso de dejetos líquidos de suínos como fertilizante do solo é uma prática comum na Região Sul do Brasil. Apesar de ter benefícios na reutilização dos dejetos, essa prática apresenta sérios riscos ambientais. Os indicadores microbiológicos de qualidade do solo são bastante sensíveis e permitem o monitoramento das condições do ambiente edáfico. Objetivou-se avaliar a qualidade microbiológica do solo de pastagens com diferentes históricos de uso sucessivo de dejetos líquidos de suínos. Determinaram-se o teor de C da biomassa microbiana, a respiração microbiana do solo, o quociente metabólico (qCO2) e a atividade das enzimas β-glicosidase, urease e hidrólise do diacetato de fluoresceína (FDA), em áreas de pastagem com uso de dejetos de suínos há dois anos (A2) e 14 anos (A14) e em área com mata nativa (MN). O uso sucessivo de dejetos de suínos em pastagem não influenciou o C da biomassa e a respiração microbiana do solo, que variaram conforme a época de coleta. O qCO2 não foi influenciado pelo uso de dejetos de suínos no solo; a atividade enzimática do solo foi influenciada pelo uso de dejetos de suínos, sendo que a urease e a FDA foram sensíveis na detecção de diferenças na atividade dos solos com uso de dejetos de suínos, enquanto a β-glicosidase não permitiu a diferenciação entre as áreas estudadas.

“…These results indicate that the conditions for soil microbial biomass were stressful in both SM systems, although the NT system was less stressful. Previous researches have indicated higher qMic in soil under NT (2.2%) than in soil under CT (1.1%) at a depth of 0-10 cm after 15 years of cultivation including the application of 90 m 3 ha -1 yr -1 of SWW (Balota et al, 2014). In another study, 14 days after the application of 300 m 3 ha -1 of SWW in a Typic Haploxeralf, the qMic reached 3.5%, whereas in the control group it was 1.5% (Plaza et al, 2007).…”

We evaluated the effects of biannual surface applications of swine wastewater (SWW) for 11 years, on chemical and microbiological attributes of a clay-textured soil under no-tillage (NT) or conventional tillage (CT) in Palotina, Paraná, Brazil. The treatments consisted of SWW doses (split into autumn-winter/spring-summer seasons) totaling 30, 60, 90 or 120 m 3 ha -1 year -1 , and a control without application, under CT or NT soil managements (SM). The experimental design was in randomized blocks with a split-plot arrangement and four replications, with SM in the plots and the doses of SWW in the subplots. After 11 years of applications of SWW, soil samples were taken at 0-10, 10-20, 20-40, and 40-60 cm of depth by the end of the winter cover crop, 44 days after the second biannual application. The treatments had only minor effects on the assessed chemical and microbiological soil properties. Available P and NO 3 --N increased with the doses of SWW at the two upper soil layers, whereas NT decreased NO 3 --N at 10-20 cm and increased P at 0-10 cm. Zn 2+ also increased with the doses of SWW, irrespectively the SM. NT increased the microbial biomass C (MBC) at 0-10 cm and 10-20 cm of soil depth, and the microbial quotient (qMic) at 0-10 cm. SM and SWW did not change the densities of heterotrophic bacteria, fungi, nitrite-oxidizers or ammonifiers at any soil depth. SM had single effects on organic C, MBC and qMic, whereas SWW had single effect only on Zn 2+ . Only available P and NO 3 --N were affected by both SM and SWW. The principal component analysis for chemical and microbiological attributes showed distinct groupings between CT and NT, and SWW rates at 0-10 cm and 10-20 cm of soil depths, the most influenced soil layers.

Soil organic matter and nutrient accumulation in areas under intensive management and swine manure application

Purpose Land use change and soil management are frequently associated to land degradation and soil organic matter (SOM) losses in tropical regions. In Brazil, in order to avoid this process, different management strategies have been applied, such as no-tillage and agricultural disposal of swine manure (SM). This study was carried out to evaluate the quantity and quality of SOM, as well as the occurrence of nutrient accumulation in soils of areas under contrasting management systems that have received consecutive applications of SM over the last decades in Brazil. Materials and methods Five land uses were sampled: native vegetation (NV), pasture with SM application (PA + SM), notillage with SM application (NT + SM), no-tillage (NT), and conventional tillage with SM application (CT + SM). Soil organic carbon (SOC), N, labile C, C management index (CMI), P, Ca 2+ , Mg 2+ , K + , Al 3+ , Fe, Zn, Mn, Cu, and H + Al were quantified.Results and discussion Except for PA + SM, the agricultural land uses caused decreases in SOC contents comparing to NV. PA + SM showed the highest C stocks, 138.9 ± 3.4 Mg ha −1 down to 0.4 m. The application of SM can be associated to the greater C stocks in PA + SM, NT + SM, and CT + SM and to the higher N contents in all land uses under this practice. Land uses which receive higher rates of swine manure application (PA + SM and CT + SM) have shown CMI greater than 100. However, this practice is associated to the accumulation of P, Cu, Na, and Zn in these soils. Conclusions The SM application is associated to improvement on C stocks and SOM quality in area under pasture, no-tillage, and conventional tillage in Paraná State, Brazil. However, this practice is the main driver of nutrient accumulation in these areas.
