ABSTRACT
In this chapter, the focus will be on the chemical constituents that are typically requested by turfgrass managers in a routine irrigation water analyses as well as some metals that are sometimes analyzed. In contrast, the emphasis in Chapter 2 was on various biological, physical, and chemical constituents in water that are not routinely included in a standard irrigation water quality analysis, but are sometimes determined to assess specific water problems, whether in a treatment facility, well, lake, irrigation lines, or after application on a site. One key point to remember is to collect a water sample from a sprinkler head on the front nine holes and again on the back nine holes of the golf course or two locations on a sports field. You need to know exactly what water quality is actually applied on the grass and you can contrast these two samples with the water source (lake, pond, river, canal, etc.) original sample.
