Question 2

A grounds manager notices turf thinning only in areas beneath mature trees. What is the BEST initial assessment tool?

Accepted Answer

Light meter to measure canopy shade levels

IPM scouting logs record pest species, population counts, locations, and dates, enabling trend analysis and action-threshold decisions.

Question 5

A turfgrass manager wants to monitor soil moisture uniformly across a large athletic field. Which technology is MOST efficient?
