GroeiBalansCourse plant sap and fertilization
During this course we tackle the functions of elements, antagonisms and synergisms, and shortage and excess phenomena. Which infuences are there at the intake of minerals? Besides that, a lot of attention is given to plant sap measurements; what these measurements contain and how to use them in practice. René van Gastel provides this course.
