Mobility and uptake of Zinc, Cadmium, Nickel, and lLead in sludge-amended soils planted to dryland maize and irrigated maize-oat rotation

Ogbazghi, Zekarias M.; Tesfamariam, Eyob Habte; Annandale, John George; De Jager, Pieter Christiaan (American Society of Agronomy, Crop Science Society of America, and Soil Science Society of America, 2015-03)

Sludge application to agricultural lands is often limited mainly because of concerns about metal accumulation in soils and uptake by crops. The objective of the study was to test the following hypotheses: (i) in the short ...
Modelling maize grain yield and nitrate leaching from sludge-amended soils across agro-ecological zones : a case study from South Africa

Ogbazghi, Zekarias M.; Tesfamariam, Eyob Habte; Annandale, John George (Water Research Commission, 2019-10)

When applying municipal sludge according to crop N requirements, the primary aim should be optimizing sludge application rates in order to maximize crop yield and minimize environmental impacts through nitrate leaching. ...
