Soybean nutritional status and seed physiological quality with swine wastewater

Abstract

Swine wastewater application is a practice that can become viable in agriculture, for minimizing fertilization costs and improving soil conditions. Therefore, it is essential to establish criteria that define appropriate application doses from the agronomic and environmental perspectives. The objective of this study was to evaluate the effects of swine wastewater doses associated with mineral fertilization on soybean nutritional status and physiological quality of seed. The experiment was conducted in the agricultural year of 2010/2011, using twenty-four drainage lysimeters in randomized block design in 4 x 2 factorial scheme, with four swine wastewater doses (0, 100, 200 and 300 m3 ha-1) applied before sowing, associated with presence and absence of mineral fertilization, in three replicates. Leaves at the flowering stage were collected for determinations of N, P, K+, Ca+2, Mg+2, Cu+2, Zn+2, Mn and Fe. Symptoms of toxicity and nutritional deficiency were observed in the crop. Furthermore, higher doses of swine wastewater caused lower physiological quality in soybean seeds.

Swine Wastewater: Impacts on Soil, Plant, and Leachate

“…Several studies have reported the impact of wastewater disposal on soil Rosa et al, 2017), leachate (Prior et al, 2009;Maggi et al, 2011;Lourenzi et al, 2014b), drained (Dal Bosco et al, 2008b;Doblinski et al, 2010;Wang et al, 2013), crops (Kessler et al, 2013a;Kessler et al, 2013b;Passarin et al, 2016;Lourenzi et al, 2014a), and biota (Tessaro et al, 2013;Brooks et al, 2014;Castaldelli et al, 2015;Tessaro et al, 2016).…”

Corn Fertilization Using Swine Wastewater and Soil-Water Environmental Quality

“…Among them, there are effects on agricultural crops (Berenger et al, 2008;Kessler et al, 2013a;Kessler et al, 2013b;Gómez-Garrido et al, 2014;Passarin et al, 2016), soil chemical , physical (Oliveira et al, 2015), and biological characteristics (Tessaro et al, 2013;Brooks et al, 2014;Castaldelli et al, 2015;Moura et al, 2016). Besides, there is the leaching (Prior et al, 2009; Corn fertilization using swine wastewater and soil-water environmental quality Eng.…”

Efeito Da Adição De Casca De Arroz Na Decomposição Anaeróbica De Dejetos Suínos Sobre Os Teores De Macro E Micronutrientes

“…Passarin et al (2016) (Lopes, et al, 2014), valor superior ao encontrado no presente estudo aos 125 dias (2510,5 mg/kg) e >267 dias (837,3 mg/kg), o que indica que a utilização do composto como fertilizante não eleva à níveis tóxicos as quantidades destes minerais no solo.…”
