Resumo: | This work aimed to study the effect of irrigation water with different electric conductivities (EC), combined with different Sodium Adsorption Relation (SAR) values on the dispersion of clay in Yellow-Red Latosol (YRL). The samples were collected in the B horizon of the soil originated from Viçosa, MG, with predominance of the clay minerals kaolinite. The soil was characterized in physical, chemical, and mineralogical terms. The treatments corresponded to percolation of NaCl and CaCl2 solutions prepared so as to have six different EC values (200; 500; 1.000; 2.000; 4.000 and 8.000 ?S cm-1) and five SAR (0, 5, 10, 20 and 40 mmolc L-1), with three repetitions, arranged in a randomized block design. The application of the solutions was made in vertical column and constant load permeameters. The solution was applied until effluent EC approached that in applied solution (C/C0 = 1,0). To evaluate the effect of the solutions applied on the soil structure, the contents of clay dispersed in water (CDW) were quantified. YRL presented non-dispersive behavior in all treatments. The YRL pH close value to its PCZ and the aluminium changing saturation complex where, apparently, important factors to the clay dispersivity control on this soil class. |

As amostras foram coletadas no horizonte B do solo com predominância do argilomineral caulinita. Os tratamentos corresponderam à percolação de soluções de NaCl e CaCl2 preparadas de forma a obter-se seis diferentes valores de CE (200; 500; 1000; 2000; 4000 e 8000 ?S cm-1) e cinco de RAS (0, 5, 10, 20 e 40 mmolc L-1), em três repetições, dispostos em um delineamento em blocos casualizados. A aplicação das soluções foi feita em permeâmetros de coluna vertical e carga constante. A solução foi aplicada até o momento em que a CE do efluente se aproximou daquela da solução aplicada (C/C0 = 1,0). Para avaliar o efeito das soluções aplicadas na estrutura do solo, foram quantificados os teores de argila dispersa em água (ADA). O LVA apresentou comportamento não dispersivo em todos os tratamentos. A proximidade do pH do LVA do seu Ponto de Carga Zero (PCZ) e a saturação do complexo de troca com alumínio foram, aparentemente, fatores de importância no controle da dispersividade da argila desta classe de solo.Universidade Federal de Viçosa - UFV2010-06-23info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.ufv.br/reveng/article/view/3710.13083/reveng.v18i3.41Engineering in Agriculture; Vol. 18 No. 3 (2010); 191-197Revista Engenharia na Agricultura - REVENG; v. 18 n. 3 (2010); 191-1972175-68131414-398410.13083/reveng.v18i3reponame:Engenharia na Agriculturainstname:Universidade Federal de Viçosa (UFV)instacron:UFVporhttps://periodicos.ufv.br/reveng/article/view/37/34Almeida Neto, Onofre Barroca dede Matos, Antonio TeixeiraMatos, Victor Pimentel deLambert, Túlio FerreiraDIAS, Erick Figueiredoinfo:eu-repo/semantics/openAccess2023-01-19T12:49:46Zoai:ojs.periodicos.ufv.br:article/37Revistahttps://periodicos.ufv.br/revengPUBhttps://periodicos.ufv.br/reveng/oairevistaengenharianagricultura@gmail.com||andrerosa@ufv.br||tramitacao.reveng@gmail.com|| reveng@ufv.br2175-68131414-3984opendoar:2023-01-19T12:49:46Engenharia na Agricultura - Universidade Federal de Viçosa (UFV)false |
