Project description
The lack of a standardized method for quality assessment of secondary P fertilizers is one of the key factors limiting their broad agricultural application. This PhD focuses on defining protocols for sample preparation, comparing methods to assess P availability in terms of time, P dose application, growing medium, and chemical interactions, and determining the efficiency of alternative plant/soil P measurements.
