“…But on the other hand, part of the P accumulated in the upper soil layers can be transferred in soluble form in the runoff solution or adsorbed to particles, to surface waters adjacent to the cultivated area, increasing the risk of water eutrophication, which is undesirable (Ceretta et al, 2010b;Wang et al, 2013;Schmitt et al, 2014).…”

“…However, when P is added successively and at high rates to the soil, for example by PS application in crop conservation systems such as no-tillage (NT), where the soil is not tilled, the total P content may increase (Berwanger et al, 2008;Lourenzi et al, 2014), and especially the content available to plants, which can be diagnosed by the method of Mehlich-1 (Gatiboni et al, 2008;Guardini et al, 2012). Thus, the saturation of the most avid adsorption sites and a reduction in adsorption energy between phosphate oxygen and functional groups of the surface of oxides and clay minerals are expected, increasing the P concentration in the solution (Guardini et al, 2012;Schmitt et al, 2014); consequently, the P transfer in surface runoff solution to surface waters increases, but also migration in the soil profile by water flow, raising the risk of contamination of subsurface waters, especially in soils with sandy surface texture (Berwanger et al, 2008;Ceretta et al, 2010b;Wang et al, 2013).…”

the application of pig slurry rates and plant cultivation can modify the soil phosphorus (P) content and distribution of chemical species in solution. the purpose of this study was to evaluate the total P, available P and P in solution, and the distribution of chemical P species in solution, in a soil under longstanding pig slurry applications and crop cultivation. the study was carried out in soil columns with undisturbed structure, collected in an experiment conducted for eight years in the experimental unit of the universidade federal de santa maria (ufsm), santa maria (rs). the soil was an Argissolo Vermelho distrófico arênico (typic hapludalf), subjected to applications of 0, 20, 40, and 80 m 3 ha -1 pig slurry. soil samples were collected from the layers 0-5, 5-10, 10-20, 20-30, 30-40, and 40-60 cm, before and after black oat and maize grown in a greenhouse, for the determination of available P, total P and P in the soil solution. in the solution, the concentration of the major cations, anions, dissolved organic carbon (doc), and ph were determined. the distribution of chemical P species was determined by software Visual minteq. the 21 pig slurry applications increased the total P content in the soil to a depth of 40 cm, and the P extracted by mehlich-1 and from the solution to a depth of 30 cm. successive applications of pig slurry changed the balance between the

“…Hence, repeated PS applications on the same fields result in the accumulation of nutrients and heavy metals in the topsoil, especially when the soil is not plowed (Ceretta et al, 2010a;Girotto et al, 2010;Guardini et al, 2012a;Xue et al, 2013). In this context, P accumulation in the soil surface is of particular concern, due to the high environmental risk of eutrophication of water bodies (Panuelas et al, 2009;Wang et al, 2013). …”

ABSTRACT:In Southern Brazil, agricultural soils are often treated over long periods with annual pig slurry (PS) applications, and their influence on soil nutrient dynamics should be monitored. This study aimed to evaluate the P forms accumulated in the soil and some biological and biochemical parameters of the P cycle after 19 successive PS applications over eight years, in a no-tillage (NT) system. Pig slurry was applied at rates of 0, 20, 40, and 80 m 3 ha -1 per crop. Several P forms (available P, microbial P, phosphatase enzyme, total organic and inorganic P) in the 0.00-0.05 and 0.05-0.10 m soil layers were analyzed. Increases up to 5,523 % in available P, 308 % in microbial P, 104 % in phosphatase enzyme activity, 91 % in organic P, 251 % in inorganic P, and 19 % in Total-P were observed in the 0.00-0.05 m soil layer in response to the highest PS rate compared to the treatment with no PS. Results also indicated that P added via PS was preferentially accumulated in the inorganic fractions (83-98 %). The increase in organic P was limited by the increase in soil organic carbon. The increase in soil microbial biomass-P was more influenced by available P, while the increase in phosphatase enzyme activity was more related to the increase in organic P and C. Therefore, PS applied to the soil affected the chemical, biological, and biochemical components of the soil P cycle.Results indicate that even half of the PS rate normally used by farmers (20 m 3 ha -1) poses a high risk of pollution of water bodies by runoff from these soils.
