Improvement in soil and sorghum health following the application of polyacrylat...
Varennes, Amarilis de; Mourato, M.P.; Martins, L.L.; Cardoso, A.I.; Mota, A.M.; Pinto, A.P.; Gonçalves, M.L.; Guiwei, QuResearch Article ; Contamination of soils with cadmium (Cd) is a serious global issue due to its high mobility and toxicity. We investigated the application of insoluble polyacrylate polymers to improve soil and plant health. Sorghum was grown in a Cd-contaminated sandy soil. Polyacrylate polymers at 0.2% (w/w) were added to half of the soil. Control soil without plants was also included in the experiment. Gro...
Amendment of an acid mine soil with compost and polyacrylate polymers enhances ...
Varennes, Amarilis de; Queda, Cristina Cunha; Guiwei, QuMany soils derived from pyrite mines spoils are acidic, poor in organic matter and plant nutrients, contaminated with trace elements, and support only sparse vegetation. The establishment of a plant cover is essential to decrease erosion and the contamination of water bodies with acid drainage containing large concentrations of trace elements. We tested the application of compost and polyacrylate polymers to pr...
