The use of sewage sludge in agriculture and recovery of degraded areas has been shown as a promising alternative for its final destination. Studies on micronutrient levels after sludge application are necessary to avoid soil contamination at toxic levels. The objective of this work was to verify the micronutrient contents in the soil profile and pH, up to one-meter-deep, nine years after the application of sewage sludge and planting of native species of the Atlantic Forest. The experiment was implemented in a degraded Quartzeneic Neosol and conducted in randomized blocks with four replicates and eight treatments, consisting of six doses of sewage sludge (0, 2.5, 5, 10, 15 and 20 Mg ha-1, with supplementation of potassium due to low concentration in the residue), besides the control treatment, mineral fertilization and only potassium supplementation. After nine years, the contents of all micronutrients evaluated presented a significant response to the application of the treatments, and the application of sewage sludge provided an increase in their contents. Soil pH remained stable at sites receiving mineral fertilization and potassium supplementation. Only manganese and zinc showed mobility in the soil profile. The application of sewage sludge in degraded soil increases the micronutrient content and decreases its movement in the soil profile, and the application of the maximum dose of the residue does not provide toxic levels of these elements in the soil in the long term.

Abstract Aims The objectives of this study were to examine the long-term substitution of mineral phosphorus (P) fertilizers with manure (M) plus nitrogen (N) fertilizers and how they affect the forms of P that occur in soil, soil P distribution, and plant growth.Methods We used a solution of 31P nuclear magnetic resonance (31P-NMR) spectroscopy to study the correlations between long-term fertilization regimes and the forms of P that occur at different soil depths. Then we investigated yield, plant growth, and soil properties.Results A 40-year field experiment showed that the use of M + N fertilizers can significantly improve plant growth and yield. The proportion of organic P in the 20-40 cm soil layer was significantly increased by long-term M fertilization. The concentrations of various forms of P (orthophosphate, pyrophosphate, diesters, monoesters, and total inositol hexakisphosphate, IHP) in topsoil increased significantly with the combination of M with N + P mineral fertilization. The addition of M greatly increased the stereoisomers of IHP (myo-IHP, scyllo-IHP, neo-IHP, and D-chiro-IHP) and the proportion and concentration of corrected diesters. There were no significant differences in the pyrophosphate contents of the 40-60 cm soil layer according to fertilization type and year of fertilization. There were also no significant differences in IHP stereoisomers and diesters according to fertilization year. The P forms that contributed to corn yield were orthophosphate, diester, and IHP. Further, pyrophosphate made no significant contribution to corn growth. Conclusions Over the long-term, pig manure can significantly increase the amount of orthophosphate that is directly absorbed by crops and the amount of IHP stereoisomers that can be used by plants. Orthophosphate and IHP are the two key factors that have a positive effect on plant growth.
