Many classes teach about the corn plant in the winter (when they don’t have corn stalks planted) or they don’t have access to get a full stalk for the classroom teaching. Also many times they can not replicate the distress that nutrient deficiencies cause.
Allows you to always have a corn stalk in your classroom with both healthy leaves and leaves with nutrient deficiencies
Allows your students to visually understand the different issues of each deficiency so when they see it in the field, they can know what it is and how to correct it
Teach students these important signs so that they do not loose money due to crop loss
