H (Hendrik) Holwerda, MSc

Since 2023 I work as PhD candidate at team Sustainable Soil Use in collaboration with the department of Soil Chemistry and Chemical Soil Quality. 

For my PhD research I study the agronomic relations between P fertilization and crop response based on long-term field experiments on calcareous clay soil and non-calcarous sandy soil. Subsequently, I study how P speciation in long-term field experiments alters due to P fertilization and how alteration of P speciation affects agronomic soil P tests.
