“…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.…”

“…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.…”

“…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.

“…However, since the volume of manure produced on swine farms is usually great and crop fields are small, farmers frequently repeat applications of swine fertilizer on the same areas. 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).…”

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.

“…In addition, these elements may have been adsorbed due to the presence of iron oxides and OM, and to the pH reduction, factors that directly hamper its bioavailability and mobility in the system (Mellis et al, 2004). High Cu 2+ contents can cause phytotoxic effects (Sodré et al, 2014) and contaminate surface waters when transported through the sediments (Girotto et al, 2010). According to CQFSRS/SC (2004), the contents of Zn 2+ and Cu 2+ in the soil are considered as adequate for annual crops (> 0.5 mg dm 3 and > 0.4 mg dm 3 , respectively).…”

A B S T R A C TIn the long run, swine wastewater can provide benefits to the soil-plant relationship, when its use is planned and the potential environmental impacts are monitored. The objective of this study was to investigate the effects of continuous application of swine wastewater, associated with mineral fertilization, after six years of management in no-tillage and crop rotation (14 production cycles), on the chemical conditions of the soil and the corn crop. The doses of wastewater were 0, 100, 200, 300 m 3 ha -1 during the cycle. The effects of the association between mineral fertilization at sowing and swine wastewater were evaluated simultaneously. Swine wastewater at the dose of 100 m 3 ha -1 promoted availability and absorption of P, K + , Mg 2+ and Zn 2+ without causing toxicity to plants or damage to the soil, constituting a viable, low-cost alternative of water reuse and fertilization for farmers. The nutrients N, P, K + and B must be complemented with mineral fertilization. Special attention should be directed to the accumulation of Zn 2+ in the soil along the time of swine wastewater application.Água residuária de suinocultura e adubação mineral no cultivo do milho R E S U M O Em longo prazo a água residuária da suinocultura pode oferecer benefícios à relação solo-planta, quando planejado o uso e monitorados possíveis impactos ambientais. O objetivo do trabalho foi investigar os efeitos da aplicação continuada de água residuária de suinocultura associada com adubação mineral após seis anos de manejo em plantio direto e sucessão de culturas (14 ciclos de produção) acerca das condições químicas do solo e da cultura do milho. As doses de água residuária foram 0, 100, 200, 300 m 3 ha -1 durante o ciclo. Simultaneamente foram avaliados os efeitos da associação de adubação mineral na semeadura com água residuária de suinocultura. A água residuária da suinocultura na dose de 100 m 3 ha -1 proporcionou disponibilidade e absorção de P, K + , Mg 2+ e Zn 2+ sem causar toxicidade às plantas ou danos ao solo constituindo viabilidade de reúso de água e fertilização alternativa de baixo custo ao produtor. Os nutrientes N, P, K + e B devem ser complementados com adubação mineral. Atenção especial deve ser direcionada ao acúmulo de Zn 2+ no solo, ao longo do tempo de aplicação de água residuária da suinocultura.
