Alteration of Physical Attributes and Production in Fertigated Soil With Swine Effluent

Abstract

Purpose: The objective of this study was to evaluate the effects of the use of different swine wastewater (ARS) in electrical (CEes) and hydraulic (K0) conductivity in soil grown with tomato, as well as in tomato yeld.   Method/design/approach: The literature review showed that studies have been based on the application of residues replacing evapotranspirometric demand, causing deleterious effects to soil and plants.   Results and conclusion: the mineral fertilization was more effective in the ionization of the soil solution than the ARS, presenting higher values of Cees in relation to the treatments that receive smaller ARS slides and the K0 increased due to the contribution of salts and organic matter, resulting from mineral fertilization, irrigation and fertigation with ARS, which caused soil restructuring   Research implications: main managerial, academic, and/or social contributions of the research.   Originality/value: This study applies ARS slides based on nitrogen doses, as it is element in higher relative concentration, seeking to determine contents that may indicate higher ARS consumption and higher production..
