Soil chemical alterations of a Dystroferric Red Latosol (Oxisol) treated with an alkaline effluent from a pharmaceutical industry

Abstract

Effluents from different industrial supply conglomerates are often discarded in the environment without proper treatment. The concern for an economically viable industrial production line, which is both environmentally sound and socially acceptable, is increasing. Some of these effluents are alkaline in nature and may be used as an alternative to chemical conditioners for acidic soils in agricultural systems. This research aimed to evaluate changes in the chemical attributes of a Dystroferric Red Latosol (Oxisol) after application of an effluent from a pharmaceutical industry. The experiment was conducted in a greenhouse using PVC tubes of 1-m length and a 0.2-m diameter filled with soil and different doses of the effluent. After 3 days, 100 mm of water was applied to each treatment. The PVC tubes were incubated for 30 days; thereafter, the tubes disassembled, and soil chemical analysis were ResumoOs efluentes das diversas cadeias produtivas industriais são muitas vezes descartados no ambiente sem tratamento adequado. A preocupação por uma linha de produção industrial economicamente viável, ambientalmente correta e socialmente aceita é cada vez mais preconizada. Alguns desses efluentes apresentam caráter alcalino, e podem ser utilizados como condicionadores químicos de solos ácidos, em sistemas agrícolas. Objetivou-se com a realização do presente trabalho, avaliar alterações químicas de um LATOSSOLO VERMELHO distroférrico, após aplicação de efluente da indústria farmacêutica. O experimento foi realizado em casa de vegetação e conduzido em tubos de PVC de 1 m de comprimento e 0,2 m de diâmetro. Nos tubos, preenchidos com solo, foram aplicadas diferentes doses do efluente. Após 3 dias, 100 mm de água foi aplicado sobre cada tratamento. As colunas foram incubadas por 30 dias, posteriormente desmontadas e feitas análises químicas nas diferentes profundidades: 0-0,2; 0, 2-0,4; 0,4-0,6; 0,6-0,8 e 0,8-1,0

Application Effect of Different Rates of Wastewater From Gelatin Production in the Chemical Attributes of the Soil

“…Regarding the levels of P in depth, it was observed that the effects of the application of GIW were restricted mainly to the superficial soil layer (0-0.05 m), since there was no migration of the nutrient to the lower layers of the soil profile ( Figure 2B). The same observations was obtained by Esper Neto et. al.…”
