• Selection of personal protective equipment (PPE) for the task
• the collection and care of the sample
• the use of appropriate tools and equipment
• a sample free from contaminants and organic debris
• cores taken in a random pattern that are uniform across the area being sampled
• the removal of sample cores to an appropriate depth
• a thorough mixing of the sample
• a study of the soil for macronutrients, micronutrients, pH, composition of sand, silt, clay, and organic matter.

Process/Skill Questions:

• What is the purpose of conducting a soil test before planting?
• How can the pH of soil be adjusted to increase or decrease acidity or alkalinity?
• What effect does pH have on nutrient availability?
• What plant species typically grow in acidic conditions? What plant species typically grow in alkaline conditions?
