Advanced Lesson 1.15 Garden ER

Lesson Overview

Conditions in the garden are in constant flux. Nutrients move through the soil strata becoming available and unavailable as plants develop. In this lesson, Students will experiment with macronutrient deficiencies to observe first-hand the effect each ha on plant development.

Teach the Teacher

Method

Nutrient levels are extremely important to plant development at almost all stages. Though plants are generally resilient the deficiency or absence of a key nutrient at the wrong time can destroy all chances of a bountiful harvest.

Devise a series of three A/B tests that compare plant development when one primary nutrient (N,P,K) is deficient. Compare it to plant development in perfectly balanced soil.

How is development affected when nitrogen, potassium, or phosphorus is deficient? Is there an impact on yield or fruit size?
