Effect of Biogas Digestate on Growth and Some Potential Toxic Element Concentrations of Wheat

Abstract

Documentation Centre (NIDOC) some potential toxic element (B, Cd, Cr, Ni, Co, and Pb) concentrations of wheat grown under greenhouse conditions. For this reason, 0, 15, and 30 tha -1 of BD were applied to the soils and incubated for 0, 30, and 60 days. After the end of the incubation period wheat seeds were sawn and left for growth for 2 months. The results indicated that BD dosages and incubation periods increased plant dry weight. Applications of incubated BD did not affect B, Cd and Co concentrations of wheat, while Cr and Ni concentrations decreased generally with the BD dosages. Similarly, incubation showed a decreasing effect on Pb concentration of wheat. Plant Co, Cr, and Pb uptakes did not vary with the applications of BD, other element uptakes increased in the parallels of plant dry weights. The element concentrations of wheat were in the ranges of acceptable levels. So, it was concluded that the application of BD did not pose a risk for potentially toxic elements on the growth of the wheat.
