Abstract
In this paper we explore the accumulation of different phosphorus P fractions in soil submitted to successive applications of pig slurry PS and deep pig litter DL After 88 months of notill crop cycles soil samples were collected in the following treatments control C PS applications equivalent to 90 and 180 kg N ha−1 PS90 and PS180 and DL applications equivalent to 90 and 180 kg N ha−1 DL90 and DL180 The cumulative application of P of the C PS90 PS180 DL90 and DL180 treatment was 0 303 606 825 and 1650 kg P ha−1 respectively The soil samples were then submitted to P chemical fractionation Successive applications of 303 and 606 kg P ha−1 in PS form and 825 and 1650 kg P ha−1 in DL form increased P levels down to 20 cm depth especially in the labile inorganic fraction extracted by anion exchange resin and 05 M NaHCO3 and to a lesser extent extracted by 01 M NaOH Successive additions of PS180 and DL180 increased the levels of organic P extracted by 05 M NaHCO3 01 M NaOH and 05 M NaOH and successive applications of PS and DL caused P accumulation in the soil profile especially in labile fractions This increased the availability to plants but also increases the potential for environmental contaminationTo the Social Technologies for Water Management Project TSGA to the Santa Catarina Research Foundation FAPESC and to the National Council for Scientific and Technological Development CNPq for their financial support To the Coordination for Continuing Education of Personnel in Higher Education CAPES for granting a Master’s degree scholarship to the first to the sixth author
