Mineral Nutrition

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.
