Collar Decline and What You Can Do About It
Collar decline is normally not the result of just one causal agent. Typically, it is the combination of numerous factors that result in lower quality turfgrass on collars than in surrounding areas. The summer months bring higher temperatures and drought stress, making this the period when most collar decline occurs.
Let’s look at some causes of collar decline and how you can remedy each one.
Auditing Your Field’s Irrigation System
An irrigation audit measures how much and where the system is watering. STMA recommends the “catch can” method to conduct an audit, which involves placing catch cans in a grid pattern on the field. After leaving the system on for a period of time, you measure the water in each catch can and identify discrepancies between different locations on the field.
