Resumo: | The use of the system, handling and time adoption of these can effectively alter the quantity of organic matter (OM) and change the cycling of nutrients in the soil. This paper aimed at evaluating the availability of nutrients and OM contents in an Oxisol (Xanthic Ferralsol) located within a Cerrado area (Savannah ecosystem) of the Piauí State in Brazil, after years under different soil use and management systems. The treatments consisted of soils under no-tillage for three, six and nine years (NTS3, NTS6, and NTS9); pasture for two and six years (PA2 and PA6, respectively); eucalyptus plantation for six and 12 years (EU6 and EU12); conventional tillage system for two and eight years (CTS2 and CTS8) and native Cerrado (NC), which represented conditions of equilibrium. For each area, we assessed the levels of OM, pH in water, Al3+, H+ + Al3+, P, K+ , Ca2+ and Mg2+ at four soil depths (0.0-0.10, 0.10-0.20, 0.20-0.30 and 0.30-0.40 m) as well as the levels of Cu, Mn, Zn, Fe, B and S at 0.0-0.40 m depth, all with four replicates. Use and management systems provided significant effects on the availability of soil macronutrients and OM contents, but have inadequate levels of micronutrients in the soil, especially Boron. In areas under tillage, there is an increase in pH, availability of nutrients and OM in the surface layer, especially during the first six years of adoption of the system, while in the areas with nine years; there were an increase in P levels in subsurface. The areas under cultivation with eucalyptus show higher potential in increasing the OM levels in soil subsurface layers. |

Este trabalho teve como objetivo avaliar a disponibilidade de nutrientes e o teor MO em um Latossolo localizado em uma área de Cerrado (ecossistema Savana) do estado do Piauí no Brasil, após anos sob diferentes sistemas de uso e manejo do solo. Os tratamentos consistiram de solos sob de plantio direto com três, seis e nove anos de cultivo (NTS3, NTS6 e NTS9) áreas sob pastagem com dois e seis anos de cultivo (PA2 e PA6), áreas sob plantio de eucalipto com seis e doze anos de cultivo (EU6 e EU12), áreas sob sistema plantio convencional com dois e oito anos de cultivo (CTS2 e CTS8) e Cerrado nativo (NC), representando uma condição de equilíbrio. Para cada área, foram avaliados os teores de MO, pH em água, Al3+, H+ +Al3+, P, K+, Ca2+, Mg2+, em quatro profundidades do solo (0-10, 10-20, 20-30 e 30-40 cm) e teores de Cu, Mn, Zn, Fe, B e S, na profundidade de 0-40 cm, todos com quatro repetições. Os sistemas de uso e manejo proporcionaram efeitos significativos na disponibilidade de macronutrientes no solo e nos teores de MO, mas apresentam níveis inadequados de micronutrientes no solo, especialmente boro. Nas áreas de plantio direto, há aumento de pH, disponibilidade de nutrientes e MO na camada superficial, especialmente nos primeiros seis anos de adoção do sistema, enquanto nas áreas com nove anos, houve um aumento nos níveis de P em subsuperfície. As áreas cultivadas com eucalipto apresentam maior potencial de aumento dos teores de MO nas camadas subsuperficiais do solo.Universidade Federal Rural de Pernambuco2018-06-11T17:51:26Z2018-06-11T17:51:26Z2017info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/articleapplication/pdfLUSTOSA FILHO, J.

The use of the system, handling and time adoption of these can effectively alter the quantity of organic matter (OM) and change the cycling of nutrients in the soil. This paper aimed at evaluating the availability of nutrients and OM contents in an Oxisol (Xanthic Ferralsol) located within a Cerrado area (Savannah ecosystem) of the Piauí State in Brazil, after years under different soil use and management systems. The treatments consisted of soils under no-tillage for three, six and nine years (NTS3, NTS6, and NTS9); pasture for two and six years (PA2 and PA6, respectively); eucalyptus plantation for six and 12 years (EU6 and EU12); conventional tillage system for two and eight years (CTS2 and CTS8) and native Cerrado (NC), which represented conditions of equilibrium. For each area, we assessed the levels of OM, pH in water, Al3+, H+ + Al3+, P, K+ , Ca2+ and Mg2+ at four soil depths (0.0-0.10, 0.10-0.20, 0.20-0.30 and 0.30-0.40 m) as well as the levels of Cu, Mn, Zn, Fe, B and S at 0.0-0.40 m depth, all with four replicates. Use and management systems provided significant effects on the availability of soil macronutrients and OM contents, but have inadequate levels of micronutrients in the soil, especially Boron. In areas under tillage, there is an increase in pH, availability of nutrients and OM in the surface layer, especially during the first six years of adoption of the system, while in the areas with nine years; there were an increase in P levels in subsurface. The areas under cultivation with eucalyptus show higher potential in increasing the OM levels in soil subsurface layers. |
