Resumo: | The physical conditions of the soil are directly related to management practices and relief format. Lack of proper management can lead to soil erosion and consequent degradation of these areas. Currently, studies of spatial variability analysis to enable better decisions and resolutions of such problems. The present study aimed to evaluate the spatial variability of soil water infiltration, soil density and texture in the hilly area of the degradation process. The survey was conducted in the hilly area cultivated with grassland, located between Areia and Remigio, two towns from Paraíba state. The soil was sampled at the regular grid with mesh (20x20m) between sample points, making a total of 49 points, into two depths, 0-10 cm, 10-20 cm, totaling 98 samples. The analyze of spatial variability was doing by semivariogram geostatistical analysis, with data interpolation by kriging and make maps. All of them physical attributes analyzed presents spatial dependence since no one showed pure nugget effect. It was verified through the maps that there was a very clear relationship between infiltration and other soil physical characteristics, observing this correlation mainly in the upper southwest slope. |

A falta de manejo adequado pode levar os solos a processos erosivos e consequentemente degradação dessas áreas. Atualmente, estudos de variabilidade espacial permitem obter uma melhor análise para tomada de decisões e resoluções das referidas problemáticas. Pensando nisso, o presente estudo teve como objetivo avaliar a variabilidade espacial da infiltração de água no solo, densidade do solo e textura em área de encosta sobre processo de degradação. A pesquisa foi realizada em área de encosta com cultivo de pastagem, localizada entre os municípios de Areia (PB) e Remígio (PB). O solo foi amostrado em grade com malha regular (20 x 20m) entre pontos amostrais, perfazendo um total de 49 pontos em duas profundidades (0-10 cm; 10-20 cm), totalizando 98 amostras. Para a análise da variabilidade espacial foi utilizado a geoestatística, por meio da análise semivariográfica, interpolação dos dados por krigagem e construção de mapas de isolinhas. Todos os atributos físicos analisados apresentaram dependência espacial, uma vez que nenhum deles mostrou efeito pepita puro. Pôde-se verificar através dos mapas que houve uma relação muito clara entre a infiltração e os demais atributos físicos do solo, observando essa correlação principalmente na parte superior sudoeste da encosta.Universidade Federal Rural do Semi-Árido2015-11-18info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.ufersa.edu.br/caatinga/article/view/387410.1590/1983-21252015v28n406rcREVISTA CAATINGA; Vol. 28 No. 4 (2015); 53-63Revista Caatinga; v. 28 n. 4 (2015); 53-631983-21250100-316Xreponame:Revista Caatingainstname:Universidade Federal Rural do Semi-Árido (UFERSA)instacron:UFERSAporhttps://periodicos.ufersa.edu.br/caatinga/article/view/3874/pdf_305Copyright (c) 2023 Revista Caatingainfo:eu-repo/semantics/openAccessLima, Franciezer Vicente deSilvino, Guttemberg da SilvaMelo, Richardson Soares de SouzaLira, Elder CunhaRibeiro, Thiago de Souza2023-07-03T16:37:04Zoai:ojs.periodicos.ufersa.edu.br:article/3874Revistahttps://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:2024-04-29T09:46:10.712266Revista Caatinga - Universidade Federal Rural do Semi-Árido (UFERSA)true |
