Design & Construction

In this unit, you will learn about plant nutrition, application of macro- and microelements, slow-release and water-soluble fertilizers, relationships between mineral nutrition and pH and E.C. You will also learn about nutritional monitoring and how to calculate parts-per-million for fertilizer solutions.

You may navigate through each section by clicking the links below, or by clicking the links in the navigation bar to the left. There is also a NEXT button and a BACK button at the bottom of each page.
