“…Organic matter was not significantly altered by the treatments (Figure 2a), a result similar to that observed by Muraishi et al (2011) andScherer et al (2010). However, Lourenzi et al (2011) found different results, with increasing organic matter in deeper soil layers after pig slurry application.…”

“…However, in lower layers (0.025-0.40 m) exchangeable K increased with an increasing application rate of pig slurry, and this is somewhat at odds with results found by Scherer et al (2010) in a Cambisol and in an Inceptisol soil in the west of Santa Catarina, Brazil; it is also at odds with results reported by Queiroz et al (2004) in a Ultisol soil in Rio Grande do Sul, Brazil, where exchangeable K was found to accumulate in the upper soil layers and to decrease in deeper layers after pig slurry application.…”

SUMMARYPig slurry applied to soil at different rates may affect soil properties and the mobility of chemical compounds within the soil. The purpose of this study was to evaluate the effects of rates of pig slurry application in agricultural areas on soil physical and chemical properties and on the mobility of glyphosate through the soil profile. The study was carried out in the 12 th year of an experiment with pig slurry applied at rates of 0 (control), 50, 100 and 200 m 3 ha -1 yr -1 on a Latossolo Vermelho distrófico (Hapludox) soil. In the control, the quantities of P and K removed by harvested grains were replaced in the next crop cycle. Soil physical properties (bulk density, porosity, texture, and saturated hydraulic conductivity) and chemical properties (organic matter, pH, extractable P, and exchangeable K) were measured. Soil solution samples were collected at depths of 20, 40 and 80 cm using suction lysimeters, and glyphosate concentrations were measured over a 60-day period after slurry application. Soil physical and chemical properties were little affected by the pig slurry applications, but soil pH was reduced and P levels increased in the surface layers. In turn, K levels were increased in sub-surface layers. Glyphosate concentrations tended to decrease over time but were not affected by pig slurry application. The concentrations of glyphosate found in different depths show that the pratice of this application in agricultural soils has the potential for contamination of groundwater, especially when the water table is the surface and heavy rains occur immediately after application.Index terms: soil fertilization, physical and chemical properties, pollutant transport, pesticide.(1) Received for publication on April 24, 2013 and approved on June 9, 2014. RESUMO: EFEITOS DE DOSES DE DEJETOS LÍQUIDOS DE SUÍNOS SOBRE OS ATRIBUTOS FÍSICOS E QUÍMICOS DO SOLO E SOBRE A MOBILIDADE DO GLIFOSATOOs dejetos líquidos de suínos são aplicados no solo, como fertilizantes, em diferentes doses. Isso pode interferir nos atributos do solo e na mobilidade de espécies químicas. Este trabalho teve por objetivo avaliar a influência das doses de dejeto líquido de suínos aplicadas em áreas agrícolas sobre os atributos químicos e físicos do solo e sobre a mobilidade de glifosato no perfil do solo. O trabalho foi realizado no 12º ano de condução de um experimento, com aplicação de dejeto líquido de suínos em Latossolo Vermelho distrófico, com doses anuais de 0, 50, 100 e 200 m 3 ha -1 ano -1 . Na testemunha (dose 0), houve reposição das quantidades de P e K exportados pelos grãos das culturas. Em cada parcela, foi realizada a determinação dos atributos físicos (densidade, porosidade, textura, condutividade hidráulica do solo saturado) e químicos (teor de matéria orgânica, pH, P extraível e K trocável) do solo. Amostras de solução do solo foram coletadas em seu perfil com o uso de lisímetros de sucção, sendo determinadas as concentrações de glifosato durante 60 dias. Os atributos físicos e químicos do solo foram pouco influenci...

“…There are several reports in the literature of increased levels of soil nutrients after pig slurry application under field conditions (Ceretta et al, 2003;Scherer et al, 2010;Girotto et al, 2010;Veiga et al, 2012). However, these studies used organic fertilizers with a higher dry matter content compared with the biofertilizer used in this experiment.…”

“…According to these authors, there was no increase in soil pH, and K and organic C after applying the organic fertilizer. Scherer et al (2010) found that in areas treated with swine waste in the long term (around 15 years, and between 20 and 25 years), the P, K, Cu and Zn concentrations increased markedly in the soil surface layers, especially in 0-0.05 m. Girotto et al (2010) found linear increases in available Cu and Zn concentrations in soil layers of a no-tillage area treated with 17 applications of up to 80 m 3 ha -1 of pig slurry over 78 months. According to the authors, the levels of available Cu and Zn in the 0-0.10 m soil layer of the treatment with the highest rate of organic fertilizer were, on average, 12 and 24 times higher, respectively, than in the control.…”

“…Several reports in the literature mention improvements in soil fertility and increases in crop yields when using pig slurry as organic fertilizer, without having gone through biodigestion (Ceretta et al, 2003;2005;Scherer et al, 2010;Lourenzi et al, 2014). However, successive applications of this organic fertilizer can promote excessive increases in P, Cu and Zn in soil, posing a potential contamination risk of soil and surface and subsurface water bodies Girotto et al, 2010;Veiga et al, 2012).…”

Organic materials subjected to a process of anaerobic digestion in a digester produce biofertilizer that can be used in agriculture as nutrient source. The objective of this study was to evaluate the effect of pig slurry biofertilizer on soil chemical properties and on corn yield and nutrient concentrations in leaves and kernels. The experiment was conducted in the field from November 2012 to April 2013, and was arranged in a randomized block design with seven treatments and four replicates. The treatments consisted of doses of pig slurry biofertilizer (0; 40; 80; 120; 160; 200 and 240 m3 ha-1), applied to the soil surface in a single application, at stage V2 of corn plants. Thirty-three days after biofertilization, soil samples were collected in each plot. Corn was harvested 129 days after sowing. Doses up to 240 m3 ha-1 of pig slurry biofertilizer applied to soil with good fertility did not influence soil chemical properties and corn yield. The use of pig slurry biofertilizer had no detectable effect on nutrient concentrations in corn leaves and kernels.

Response of Arbuscular Mycorrhizal Fungi in Different Soil Tillage Systems to Long‐Term Swine Slurry Application

et al. 2014

Swine slurry is a common agricultural fertilizer in many countries. However, its long-term use in large amounts can cause excess nutrient accumulation, alter soil compounds, and potentially influence critical microbial populations such as arbuscular mycorrhizal fungi, which have important roles in plant nutrition and soil sustainability. This work determined if arbuscular mycorrhizal status, external mycelium, and glomalin-related soil protein content were affected by long-term swine slurry application to different soil tillage systems. The experiment was conducted on a clayey oxisol, in southern Brazil. Swine slurry (0, 30, 60, 90, and 120 m 3 ha À1 y À1 ) was applied for 15 years to conventional tillage and no tillage soil prior to the summer (soybean or maize) and winter (wheat or oats) crop seasons. Swine slurry decreased mycorrhizal root colonization, spore number, and total external mycelium. Swine slurry increased active external mycelium and both easily extractable and total glomalin-related soil protein. No-tillage soil had more glomalin-related soil protein than conventional tillage soil. The most significant response variables were root colonization, easily extractable glomalin-related soil protein, and total external arbuscular mycorrhizal mycelia. Long-term application of swine slurry in this environment, even at high rates, did not adversely affect crop yield but did influence arbuscular mycorrhizae fungi and their products in the soil environment. Benefits of swine slurry application for crop nutrition must be weighed against potential adverse consequences for the size, activity, and benefits of the mycorrhizal community to subsequent annual crops.
