It is summer in the northern hemisphere, and that means many turf areas will require irrigation. Here are 5 links that I think provide some valuable information about how to irrigate effectively. Or at least, how to think about soil moisture and water application in an ideal situation. But be warned – these have also been among the most unpopular (or at least controversial!) posts I've made. 

• Summertime syringing to cool bentgrass greens: I wouldn't do it today
• More advantages of frequent irrigation
• On the seductive attractions of metric units
• For irrigation, which is better? Deep and infrequent, or light and frequent?
• Irrigation management in summer: timing, amount, syringing, and water quality

The numbers don't lie. Frequent irrigation can be used to maintain lower soil moisture content than infrequent irrigation. Canopy temperatures of bentgrass are "not markedly affected by varying the volume or timing of syringing applications." And the metric system, if you are using soil moisture meters, makes it a lot easier to manage the soil moisture.
