Resumo: | The study was conducted in irrigated commercial orchards of ‘Paluma’ and ‘Pedro Sato’ guavas, which were mapped with a Garmin GPS unit (Cx60). Sixty five sampling points were marked on a 21 x 21 m sampling grid. Gravimetric humidity and soil penetration resistance (SPR) were evaluated with the help of an automated penetrometer rod with a type 3 cone at a 45º angle (maximum SPR 15,100 kPa). Data with non-normal distribution were analyzed by geostatistics and interpolation by ordinary kriging. SPR values were higher where machine traffic occurs than on the lines where the crop is planted. There was spatial variability of the SPR among the layers evaluated, with the layer between 0.10-0.20 m, on the line of the machine traffic, presenting a higher SPR (>4000 kPa). |

Houve a demarcação de 65 pontos de amostragem, demarcados em grade amostral de 21 x 21 m, sendo avaliadas a umidade gravimétrica e a resistência do solo à penetração (RSP), com auxilio de um penetrômetro automatizado, haste com cone tipo 3 com ângulo de 45º (RSP máximo de 15.100kPa). Os dados com distribuição não normal foram analisados por geoestatística e interpolação por krigagem ordinária. Os valores de RSP, onde ocorre o tráfego de máquinas, foi maior do que o avaliado na linha de plantio da cultura. Houve variabilidade espacial da RSP entre as camadas avaliadas, sendo que a camada entre 0,10-0,20 m, na linha do tráfego de máquinas, apresentou a maior RSP (>4000kPa).Universidade Federal Rural do Semi-Árido2018-10-17info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.ufersa.edu.br/caatinga/article/view/695410.1590/1983-21252018v31n421rcREVISTA CAATINGA; Vol. 31 No. 4 (2018); 980-986Revista Caatinga; v. 31 n. 4 (2018); 980-9861983-21250100-316Xreponame:Revista Caatingainstname:Universidade Federal Rural do Semi-Árido (UFERSA)instacron:UFERSAenghttps://periodicos.ufersa.edu.br/caatinga/article/view/6954/9868Copyright (c) 2018 Revista Caatingainfo:eu-repo/semantics/openAccessSouza, Wilson José Oliveira deRozane, Danilo EduardoSouza, Henrique Antunes deNatale, WilliamSantos, Paulo André Fernandes dos2023-07-20T13:55:16Zoai:ojs.periodicos.ufersa.edu.br:article/6954Revistahttps://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:2024-04-29T09:46:32.375405Revista Caatinga - Universidade Federal Rural do Semi-Árido (UFERSA)true |
