Letter: How fertilizer ties into agriculture curriculum Op-Ed · March 15, 2013
For the past few articles we’ve been talking about fertilizer and what it does to soils, but how does it tie into our agricultural education courses?
Currently we’re preparing to start our greenhouse management unit. In the course of this unit, we will plant various vegetables and flowers to sell to the community.
It is important that we know and understand plant nutrient requirements in order to produce the highest quality plants.
Because we use soilless planting media, it only offers minimal nutrients for plant growth. We will be using fertilizer applied through water. This fertilizer will be a 20-20-20 mix which, as we explained in the previous articles, contains nitrogen potassium and phosphorus.
We will sell our starter plants at our plant sale in April.
