EFEITO DA ÁGUA RESIDUÁRIA DE SUINOCULTURA NA CONCENTRAÇÃO DE FERRO E MANGANÊS NA RAIZ DO TOMATE

The objective of this work was to evaluate concentration iron and manganese in the root of tomato (Santa Clara and Carmen varieties) with swine wastewater. The experimental design was randomized blocks, in a factorial scheme (5 x 2), with five replications. The treatments were: 100% raw waste water, 100% filtered waste water, 100% SODIS (Solar 1 Graduanda em Engenharia Ambiental, Instituto Federal Goiano – Campus Rio Verde, Rodovia Sul Goiana, Km 01, CEP: 75.901-170, Rio Verde – GO, e-mail: daniely_karen@hotmail.com 2 Graduanda em Engenharia Ambiental, IFGoiano – Campus Rio Verde, e-mail: rannaiany@hotmail.com 3 Doutorando em Ciências Agrárias Agronomia, IFGoiano – Campus Rio Verde, e-mail: fernandonobrecunha@hotmail.com 4 Eng.

The applied water was determined according with the evaporation of water in the soil contained in the weighing lysimeters, and each lysimeter was submitted to 100% of the water replacement (RH) when the available water capacity in the soil (AWC). The iron content present in the tomato root for the Carmen variety is higher for the 100% SODIS (Solar disinfection) water treatment with a difference of up to 32% when compared to water supply.
