Soil Chemistry after Irrigation with Treated Wastewater in Semiarid Climate 90
Oliveira,Pedro Carlos Pacheco de; Gloaguen,Thomas Vincent; Gonçalves,Roberta Alessandra Bruschi; Santos,Dionei Lima; Couto,Carolina Fonseca.
ABSTRACT Soil irrigation using treated wastewater in the Brazilian semiarid region is a promising practice as this area currently faces water scarcity and pollution of water resources by domestic sewage. The aim of this study was to evaluate the use of treated wastewater in drip irrigation and its effect on the chemistry of soil cultivated with squash (Cucurbita maxima Duch.) Coroa IAC and to verify whether there was an increase in soil salinity under a semiarid climate. The experiment was conducted for 123 days on a farm close to the sewage treatment plant, in a randomized block design with five treatments and four replications. The treatments consisted of two irrigation water depths (100 and 150 % of the evapotranspiration), two applications of gypsum to...
