“…They reported that inorganic P was the most significant form of P both in the compost and compost-amended soils. Another study reported that P forms from poultry, cattle, and swine dry manures are bioavailable and in organic in nature and dependent on Ca:P ratio in manures [34]. Ajiboye et al [35] 30 to 40% of total hog and cattle manure P and 10% of total biosolids P was extracted with water, and 21 to 32% of total P in all organic amendments was extracted with NaHCO 3 except in dairy cattle manure (45% of total P).…”

“…Highest increases were observed in Av-P and Inorg-P, because between 60 % (Cassol et al, 2001) and 99 % (Tiecher et al, 2014) of P contained in PS is in inorganic forms. This increase was up to 12.5-fold in the Av-P/Total-P ratio in the 0.00-0.05 m soil layer where PS was applied at the maximum rate (Table 4).…”

“…The field-applied P contained in PS in Brazil is estimated at around 123 thousand tons per year (Tiecher et al, 2014), representing about 3.2 % of the annual consumption of P contained in phosphate fertilizers in Brazil (3,860 thousand tons per year) (IFA, 2013).…”

“…This can be explained by the fact that P contained in PS is mostly in inorganic forms [up to 99 % according to Tiecher et al (2014)] and the remaining P in highly labile organic forms, which are easily mineralized after application to the soil. Therefore, P applied in PS has the same pattern of adsorption by soil inorganic colloids as that of P applied in mineral fertilizers, with preferential accumulation in inorganic forms.…”

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.

“…There is also the possibility of the excess supply of P causing environmental contamination leading to the eutrophication of water courses. In this case, greater attention should be paid to P fractions with greater lability and mobility in the soil, such as those associated with water-soluble inorganic phosphates, due to them having the greatest potential for causing environmental contamination (LI et al, 2014;TIECHER et al, 2014;TORRI et al, 2017).…”

Understanding the dynamics of the organic matter and nutrients in pig manure submitted to anaerobic digestion is important to assist in decision-making regarding the use of anaerobic biofertilizer in agriculture. Accordingly, this study was carried out with the objective of evaluating the changes in organic matter, quantified as the content of carbon in the humic and oxidizable fractions, and in the content of the organic and inorganic forms of phosphorus in the solid fraction of the manure, as a function of digestion time in anaerobic reactors. Evaluations were carried out after 7, 14, 21, 28, 35, 42, and 49 days of digestion, and the results were compared to the raw manure. Changes in organic matter occurred mostly in the labile fractions (fulvic acid and the F1 fraction), the content of which underwent a reduction, favoring the accumulation of more recalcitrant fractions in the final biofertilizer (humic acid and the F2, F3, and F4 fractions). Total P content did not change throughout the digestion process. However, the size of inorganic fraction of water-extractable P decreased by 16.7% after 49 days of digestion, as it was consumed by the decomposing microbiota to form stabilized organic matter, which accumulated along with the more recalcitrant fractions of P in the final biofertilizer. Therefore, the use of swine manure-derived anaerobic biofertilizer has less risk of environmental contamination with excessive P than the direct application of raw manure to the soil.
