Livestock Manure and Water Quality (CTE)

by

Students will examine the nutrients present in animal waste and identify possible environmental contaminates in the waste.

Introduction

This is the second lesson in a 4 lesson sequence.

To examine the effects of water runoff from livestock facilities, students will design a controlled experiment to test water samples from soils exposed to livestock for nitrates, phosphate, heavy metals, pH, dissolved oxygen and other factors. Students will utilize their previously collected soil samples or soil plot and design a model to simulate water run off from a livestock production facility. Alternately, students will test water runoff samples from existing livestock facilities.

At the conclusion of the experiment, students will provide a written recommendation to a county land use commission with a protocol for the optimal use of the animal effluent.
