Turfgrass Mathematics

Students in the Turfgrass Mathematics course will learn the fundamentals of solving common turfgrass math problems. This course will present examples of various mathematical problems that turfgrass managers face and provide practical methods to solve these problems. Topics for this course will include area and volume calculations, fertilizer calculations, pesticide calculations, seed rate calculations, and how to calibrate a sprayer and spreader.

What You'll Learn

At the end of the course students will be able to:

  1. Calculate area and volume.
  2. Solve dry and liquid fertilizer calculations.
  3. Solve dry and liquid pesticide calculations, including herbicides, fundgicides, and insecticides.
  4. Calculate seeding rate for an area based on Pure Live Seed (PLS).
  5. Calibrate sprayers and spreaders used for pesticide and fertilizer calculations.

Turfgrass Management Program

This course is part of the Turfgrass Management Program that includes the following component courses:

Please note: This course is primarily designed for those working in northern climates such as Oregon and Washington, Europe, Scandinavia and parts of Canada; however, course concepts may apply to other climate zones and some information on warm-season grasses is also covered. By focusing on these climates, you'll gain detailed information you can apply to your own park, field or lawn.
