| Abstract (English): |
The study was conducted in a saline-sodic Inceptisol from the Cachoeira II Irrigation Perimeter, Serra Talhada (PE), with the objective of evaluating the dynamics of basic cations and anions in a saline-sodic soil subjected to phytoremediation with Atriplex nummularia and correction with application of gypsum. Samples were taken every six months, at four times (0, 6, 12 and 18 months). The experimental design was in randomized blocks, the four treatments evaluated were: control (without any management practice), chemical correction with gypsum (no crop) and two Atriplex nummularia cultivation (1 x 1 m and 2 x 2 m plant spacing), with four replications. The results of soil analysis revealed the contribution of gypsum application and especially the cultivation of Atriplex plants in reducing the levels of salts in the soil [ABSTRACT FROM AUTHOR] |

Desenvolveu-se este trabalho em um Cambissolo salino sódico do Perímetro Irrigado Cachoeira II, Serra Talhada, PE, com o objetivo de avaliar a dinâmica de cátions e ânions básicos em um solo salino sódico submetido a fitorremediação com Atriplex nummularia e correção com aplicação de gesso. Realizaram-se amostragens semestrais com quatro coletas de solo (0, 6, 12 e 18 meses). O delineamento experimental utilizado foi de blocos ao acaso avaliando-se quatro tratamentos: controle (sem nenhum manejo do solo), correção química com gesso (sem cultivo) e dois com cultivo de Atriplex nummularia Lindl (espaçamentos 1 x 1 m e 2 x 2 m), com quatro repetiçÕes. Os resultados das análises do solo revelaram a contribuição da aplicação de gesso, especialmente do cultivo de plantas de atriplex na redução dos teores de sais no solo [ABSTRACT FROM AUTHOR] |
