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...

“…Thus, nutrient contents in the soil are expected to increase over the years (Mcdowell et al, 2001;Basso et al, 2005;Gatiboni et al, 2008;Ceretta et al, 2010a,b;Girotto et al, 2010). The chemical properties related to soil acidity are also expected to change, e.g., with increases in soil pH and base saturation, as well as a decrease in aluminum saturation (Ceretta et al, 2003;Lourenzi et al, 2011). Although there is abundant literature on the effects of pig slurry, no information was found about the effects of swine deep-litter on soil acidity parameters.…”

“…Therefore a small soil contact area is expected, with a consequent delay in the microbial biomass activity, which may stimulate total organic carbon (TOC) accumulation (Ceretta et al, 2003;Adeli et al, 2008;Lourenzi et al, 2011), particularly in the surface layers. However, increases in TOC contents are mainly associated to the manure composition, application frequency and amount (Falleiro et al, 2003;Lourenzi et al, 2011). These changes can increase the soil cation exchange capacity (CEC) R. Bras.…”

Moreover, manure can increase exchangeable aluminum adsorption, especially in the fractions of humic and fulvic acids of the organic matter (Ceretta et al, 2003), reducing the toxicity to plant roots and increasing H + adsorption (Hue & Licudine, 1999;Lourenzi et al, 2011). These changes may also be associated to an increase in soil water pH.…”

SUMMARYSuccessive applications of liquid swine waste to the soil can increase the contents of total organic carbon and nutrients and change acidity-related soil chemical properties. However, little information is available on the effects of swine waste application in solid form, as of swine deep-litter. The objective of this study was to evaluate alterations of organic carbon and acidity-related properties of a soil after eight years of pig slurry and deep-litter application. In the eighth year of a field experiment established in Braço do Norte, Santa Catarina (SC) on a sandy Typic Hapludalf samples were taken (layers 0-2.5; 2.5-5; 5-10; 10-15; 15-20 and 20-30 cm) from unfertilized plots and plots with pig slurry or deep-litter applications, providing the simple or double rate of N requirement of Zea mays and Avena strigosa in rotation.

The production of sugarcane bioethanol generates large volumes of vinasse, an effluent whose final disposal can produce an environmental impact that is of concern. The long‐term disposal of vinasse in sugarcane fields could challenge crop management, such as the performance of traditional herbicides, by changing soil properties. This study aimed to evaluate the effect of long‐term vinasse application on the field and the dissipation of atrazine and ametryn herbicides in a subtropical sugarcane agroecosystem, and to discuss the potential processes involved in it. Vinasse affected soil properties by increasing pH (12%), electrical conductivity (160%), and soil organic carbon (25%) at 0–10 cm depth of soil. Differences in the herbicide calculated sorption coefficient (Kd) varied according to the pedotransfer function applied and the herbicide type (atrazine or ametryn). During the first seven days after herbicide application, the soil underwent long‐term vinasse application and increased atrazine and ametryn dissipation 45% and 33%, respectively, compared with the conventional fertilization scheme (control). The Pesticide Root Zone Model revealed that dissipation was mediated mainly by the degradation process rather than transport or other processes. The long‐term application of vinasse in a typical sugarcane field of Tucumán, Argentina decreased the potential groundwater pollution of triazines and, adversely, reduced their bioavailability for weed control. For this, the present study presents original information about how long‐term treatment with vinasse may require an adaptation of conventional management practices such as the application of herbicides in Argentina and other sugarcane‐producing regions.
