“…Single additions of excreta more than tripled the P Ac and TP w in the 0-2 cm soil layer in 50 days. There were no sings of decreasing P solubility towards the end of the experimental period, which supports the results of Chardon et al (2007), who found manure patches to be a source of P for a long time after deposition. Repeated dung additions may result in very high soil P status, especially in areas where cattle tend to congregate.…”

“…The water extractable P in dung is composed largely of inorganic P. However, data published in the literature vary considerably due to the different extraction procedures and sample-to-solution ratios used in dung analyses (He et al 2004, Chardon et al 2007). In the present study, the composition of dung was not analysed in detail, but the smaller increase in MUP w in the dung-treated samples over that of MRP w suggests that the majority of the TP w that ended up in the soil with the dung was in inorganic form.…”

“…In the present study, the composition of dung was not analysed in detail, but the smaller increase in MUP w in the dung-treated samples over that of MRP w suggests that the majority of the TP w that ended up in the soil with the dung was in inorganic form. Even though the P in dung can be considered to be mostly inorganic, Chardon et al (2007) found that dissolved unreactive P dominated in the leachate from a manure patch deposited on permanent grassland soil. They suggested that the bacterial immobilisation of P may be responsible for this phenomenon.…”

The objective of this study was to examine the effects of urine and dung additions on the phosphorus (P) chemistry of pasture land and to compare the sensitivity of two soil extraction methods in assessing the P-loading risk. In a field experiment, urine and dung were added to soil in amounts corresponding to single excrement portions and the soil samples, taken at certain intervals, were analysed for pH H2O , acid ammonium acetate extractable P (P Ac ) and water extractable total P (TP w ), and molybdate reactive P (MRP w ). Urine additions immediately increased soil pH and MRP w , but no such response was observed in P Ac extraction due to the low pH (4.65) of the extractant enhancing the resorption of P. The P Ac responded to the dunginduced increase in soil total P similarly as did P w , which suggests that both tests can serve to detect areas of high P concentration. However, water extraction was a more sensitive method for estimating short-term changes in P solubility. In pasture soils, the risk of P loss increases as a result of the interaction of urination and high P concentration in the topsoil resulting from continuous dung excretion.

“…That is because P is predominantly found in inorganic form in the manure, readily available to plants. This may be seen in figure 1, where the greatest available P contents were observed in the first days of soil incubation, which indicates that a large part of the P present in the manure is found in the inorganic form, which is the predominant form of accumulation in soils treated with manure (Chardon et al, 2007;Gatiboni et al, 2008;Ceretta et al, 2010a;Guardini et al, 2012a;Lourenzi et al, 2013). Furthermore, the absence of tilling in the no-tillage system favors P accumulation in the soil surface layers because, in the soil, the P may be adsorbed to the surface of functional groups of reactive particles, normally forming inner sphere complexes (specific adsorption) (Barrow, 1999).…”

The application of animal manure to soil can increase phosphorus availability to plants and enhance transfer of the nutrient solution drained from the soil surface or leached into the soil profile. The aim of this study was to evaluate the effect of successive applications of organic and mineral nutrient sources on the available content, surface runoff and leaching of P forms in a Typic Hapludalf in no-tillage systems. Experiment 1 was set up in 2004 in the experimental area of UFSM, in Santa Maria (RS, Brazil). The treatments consisted of: control (without nutrient application) and application of pig slurry (PS), pig deep-litter (PL), cattle slurry (CS), and mineral fertilizers (NPK). The rates were determined to meet the N crop requirements of no-tillage black oat and maize, grown in the 2010/2011 growing season. The soil solution was collected after each event (rain + runoff or leaching) and the soluble, particulate and total P contents were measured. In November 2008, soil was collected in 2 cm intervals to a depth of 20 cm, in 5 cm intervals to a depth of 40 cm, and in 10 cm intervals to a depth of 70 cm. The soil was dried and ground, and P determined after extraction by anion exchange resin (AER). In experiment 2, samples collected from the Typic Hapludalf near experiment 1 were incubated for 20, 35, 58, 73 and 123 days after applying the following treatments: soil, soil + PS, soil + PL, soil + CS and soil + NPK. Thereafter, the soil was sampled and P was analyzed by AER. The applications of nutrient sources over the years led to an increase in available P and its migration in the soil profile. This led to P transfer via surface runoff and leaching, with the largest transfer being observed in PS and PL treatments, in which most P was applied. The soil available P and P transfer via surface runoff were correlated with the amounts applied, regardless of the P source. However, P transfer by leaching was not correlated with the applied nutrient amount, but rather with the solution amount leached in the soil profile.

“…A baixa capacidade de adsorção de P de solos arenosos (Rheinheimer et al, 2003) pode contribuir para esse deslocamento vertical. Em relação às formas químicas de P, a literatura indica tanto o deslocamento em formas inorgânicas (Chardon et al, 2007) quanto orgânicas (Djodjic et al, 2004). Deve-se considerar que a maior parte do P contido no esterco está em formas inorgânicas (P-resina) (Cassol et al, 2001).…”

Resumo -Os objetivos deste trabalho foram quantificar as concentrações de carbono e nutrientes em solos de áreas adubadas e não adubadas com esterco; quantificar as concentrações de nutrientes em amostras de esterco bovino utilizado na região e calcular o acúmulo de nutrientes resultantes dessa adubação e o potencial de perdas por lixiviação. Foram amostradas 18 áreas agrícolas, com adição anual de esterco por pelo menos dois anos e, como controle, quatro áreas sob pastagem não adubadas, coletando-se amostras de solo das camadas de 0-20, 20-40 e 40-60 cm, que foram analisadas quanto à granulometria, densidade do solo, pH, C, N e P totais, bases trocáveis, P extraível por água e por Mehlich-1. Amostras de esterco utilizadas em nove áreas também foram analisadas. A aplicação de esterco resultou em acumulações médias ao redor de 20 Mg ha -1 de C, 2 Mg ha -1 de N total e Ca, e de 0,5 a 1 Mg ha -1 de P total, K e Mg (0-60 cm). Acumulações de P solúvel em água e bases trocáveis na camada de 40-60 cm, em relação às testemunhas, indicam grande potencial de perda desses nutrientes.Termos para indexação: agricultura familiar, adubação orgânica, lixiviação de fósforo. Nutrient build up in sandy soils receiving manure additionsAbstract -The objective of this work was to quantify changes on carbon and nutrient contents in soils under continuous manure additions. Eighteen cropped fields that had received annual additions of manure for at least two years and four fields under pasture with no history of manure addition were sampled to assess if this practice results in the accumulation or losses of added nutrients. Soils samples from the 0-20, 20-40 and 40-60 cm layers were taken from each field, and analyzed with regard to their physical (particle size and soil density) and chemical (pH, total C, N and P, extractable P by Mehlich-1 and water, and exchangeable cations) properties. Manure samples used in nine fields were also analyzed for chemical composition. Manure additions resulted in a build up of nutrient stocks near to 20 Mg ha -1 of C, 2 Mg ha -1 of N and Ca, and 0.5 to 1 Mg ha -1 of P, K and Mg (0-60 cm). Water-soluble P concentrations of 7 mg kg -1 in the 40-60 cm layer indicated losses of this nutrient, the less mobile in soils. Accumulation of exchangeable cations in the 0-60 cm layer, in comparison with control areas, indicates an even greater potential for losses of these nutrients.
