Leaching of the different forms of nitrogen by the application of poultry litter, swine waste, and mineral nitrogen on corn cultures (Zea mays L.)

Abstract: Agricultural, livestock management, and industrial activities have the potential to cause high levels of contamination to the soil, surface water, and groundwater as a result of accidental or deliberate discharges of pollutants to the environment. In this study, we evaluated the contamination of groundwater by various forms of leached nitrogen (total N, ammonia, nitrate, and nitrite) arising from the application of poultry litter, swine waste, and mineral nitrogen (urea) to the soil. The study was conducted us… Show more

“…Regarding fertilization with NPK, its concentration was lower than the others, but there was a slower and increasing release starting from the second evaluation, extending until the end of the cycle. Opposite result was found by Rosa et al (2018), where working with the same sources of fertilization, observed the highest peak of total nitrogen concentration at 90 DAS, decreasing over time.…”

“…Nas Figuras 2 estão contidos os resultados das concentrações de Cu e Zn (mg.kg -1 ) no solo, em função das profundidades amostradas de 0-10, 10-20, 20-30 e 30-40 cm, em solo adubado com dejeto de suínos, cama de aves e adubação mineral. É possível constatar pela Figura 2 que o metal Zn presente na adubação ficou acumulado no perfil do solo, quando comparado com o perfil do solo testemunha (Da Rosa et al 2018). Esses resultados corroboram com os obtidos por Basso et al (2012) em áreas de lavoura e pastagem onde houve a aplicação de dejetos de suíno.…”

“…Entretanto, essas atividades são as principais responsáveis pela geração de elevada quantidade de dejetos, entre eles, os dejetos de suínos que devem ser armazenados em poços de decantação e posteriormente podem ser lançados ao solo, em áreas de cultivo, como forma de adubação orgânica (De Mera et al 2011). No entanto, essa prática tem contribuído para a contaminação do solo, mananciais superficiais e também lençol freático, quando da não observância da quantidade de dejetos a serem aplicados e a composição dos mesmos (Rosa et al 2018).…”
