Identify nutrient management practices.

Identification should include

• listing nutrients necessary for turfgrass growth
• identifying differences between quick-release and slow-release nitrogen sources
• using or describing accepted nutrient management practices for given situations
• identifying the effect of nitrogen (N), phosphorus (P), and potassium (K) on plant growth
• following current nutrient management regulations
• considering effects on water quality.

Process/Skill Questions:

• What nutrients are necessary for optimal turfgrass growth and development?
• What are the differences between quick-release and slow-release nitrogen sources?
• How do we calculate the quantity of nutrients in specific fertilizers?
• What is the importance of macronutrients in plant growth? Micronutrients?
• What is the procedure for correcting pH problems?
• What knowledge do we need to interpret soil analysis test results?
• How do we determine the quantity of fertilizer for a specific area, according to soil test results or nutrient management plan recommendations?
• What are the differences between liquid and granular fertilizers?
• What is the procedure for applying granular fertilizer?
