Resumo: The soybean-corn succession in no-tillage system (DSS) is the most common cultivation practice in the state of Mato Grosso. Soils submitted to this type of system are prone to the formation of fertility gradients and surface compaction, restricting crop productivity. The objective of this work was to evaluate the physical-chemical attributes of an Oxisol after 11 years of continuous succession of soybean and corn in direct seeding, using geostatistical analysis techniques and main components. The experiment was conducted at the Chão Nativo farm located in the municipality of Sinop, Mato Grosso, Cerrado-Amazonian ecotone. For this, a rectangular mesh was installed with 103 sampling points distributed in an area of 7.02 ha, in which the grain yield of the soybean was determined as well as the physical and chemical attributes of the soil in the layers 0-10 and 0.10 – 0.20 m. Soybean showed a grain yield between 2.83 and 3.70 Mg ha-1, which was positively correlated with the spatial distribution of pH, phosphorus and potassium. The soil presented low physical quality due to high soil resistance to penetration and macroporosity less than 10%; however, no spatial correlation of physical attributes with soybean yield was observed.

Os solos submetidos a este tipo de sistema estão propensos à formação de gradientes de fertilidade e compactação superficial, restringindo a produtividade das culturas. O objetivo do trabalho foi avaliar os atributos físico-químicos de um Latossolo Vermelho-Amarelo após 11 anos de sucessão contínua de soja e milho em semeadura direta, utilizando-se técnicas de análise geoestatística e componentes principais. O experimento foi conduzido na fazenda Chão Nativo localizada no município de Sinop, Mato Grosso, ecótono Cerrado-Amazônia. Para isso instalou-se uma malha retangular com 103 pontos amostrais distribuídos em uma área de 7,02 ha, nos quais se determinou a produtividade de grãos da soja e os atributos físicos e químicos do solo nas camadas de 0-10 e 0,10-0,20 m. A soja apresentou amplitude na produtividade de grãos entre 2,83 e 3,70 Mg ha-1, que foi correlacionada de forma positiva com a distribuição espacial do pH, fósforo e potássio. O solo apresentou baixa qualidade física devido a elevada resistência do solo à penetração e macroporosidade menor que 10 %, contudo, não foi observada correlação espacial dos atributos físicos com a produtividade da soja.Universidade Federal Rural do Semi-Árido2017-06-14info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.ufersa.edu.br/caatinga/article/view/616610.1590/1983-21252017v30n420rcREVISTA CAATINGA; Vol. 30 No. 4 (2017); 991-1000Revista Caatinga; v. 30 n. 4 (2017); 991-10001983-21250100-316Xreponame:Revista Caatingainstname:Universidade Federal Rural do Semi-Árido (UFERSA)instacron:UFERSAenghttps://periodicos.ufersa.edu.br/caatinga/article/view/6166/pdfFreddi, Onã da SilvaTavanti, Renan Francisco RimoldiSoares, Matheus BortolanzaAlmeida, Frederico Terra dePeres, Fernanda Salles Cunhainfo:eu-repo/semantics/openAccess2023-07-20T11:35:06Zoai:ojs.periodicos.ufersa.edu.br:article/6166Revistahttps://periodicos.ufersa.edu.br/index.php/caatinga/indexPUBhttps://periodicos.ufersa.edu.br/index.php/caatinga/oaipatricio@ufersa.edu.br|| caatinga@ufersa.edu.br1983-21250100-316Xopendoar:2024-04-29T09:46:26.214127Revista Caatinga - Universidade Federal Rural do Semi-Árido (UFERSA)true
