3 major elements for healthy turf grass
1) nitrogen: promotes leaf or blade growth. With a nitrogen deficiency, the blade of grass turns a light green or greenish yellow color. 2) phosphorous: promotes healthy root growth 3) potassium (aka potash):gives plant sugars, starches, protiens. Gives grass general vigor, and provides resistance to disease.

keeping park and recreation areas and facilities in their original state or as so nearly as possible.
preventative maintenace
maintaining facilities before damage occurs
Data Analysis
manipulates data thorough counting, grouping, averaging, summing, aggregating and extrapolating. *very important to public sector maintenance managers as more local governments begin to utilize performance measures to gauge agency program success.
Hardware should be selected secondarily because
most software will only run on certain types of hardware
Major equipment jobs should be noted in 2 places:
on a dated tag attached to the equipment on the inventory record kept in the maintained shop
Much of the research in regards to vandalism is
rhetorical opinion rather than factual research.
inventory records
