Unit 4: Turfgrass Cultural Practices

Lesson 3: Irrigation


Cultural practices incorporate all of the methods that can be applied to sustain healthy turfgrass. Proper use of cultural practices promotes overall health of turfgrass so plants can better withstand pest pressure and environmental stresses. Irrigation is a primary cultural practice that is necessary to supply water to turfgrass plants. When natural precipitation is not adequate, irrigation is necessary to ensure moisture for plant growth.


Upon completion of this unit, students will be able to:

  • Describe the purposes of irrigation for turfgrass areas
  • Explain turfgrass irrigation requirements
  • Determine irrigation frequency and amount
  • Compare how different soil textures affect water availability
  • Identify irrigation parts
  • Assess sprinkler distribution patterns
