- Abstract
The article discusses research examining the effects of the co-application of biosolids and drinking water treatment residuals (WTRs) on the growth of corn (Zea mays) and the bioavailability of phosphorous (P) and aluminum (Al) in Egyptian soils. The team used a quantitative greenhouse pot study to measure the effects of biosolids and drinking (WTRs) on the corn cultivar Zea mays L. cultivar single hybrid 10 in an Egyptian soil, in relation to the bioaccumulation of Olsen-P and potassium chloride (KCl)-extractable Al within plant tissues. The effect of biosolid-amended soils on corn yield under varying drinking WTR application rates and the correlation between the application rate, Al phototoxicity, and soil Olsen-P values are discussed.
