Upgrading
your field, but find yourself wondering how much you need?
How many pounds or tons or yards?
Your field
needs a serious facelift. You plan to overseed, fertilize, and use
top dressing. You're going to do the whole 10 step turf
maintenance upgrade.
So, how
do I figure out how much do I need to do the job right?
 The
overseed rate is 6 to 8 pounds per 1000 sq ft. One 50 pound
bag is good for a high school size infield. One 50 pound bag can overseed
2 little league infields. A typical high school outfield will
need 79 bags of seed.
 Apply
seed to new areas at double the rate as overseeding
or about 1015 pounds per 1000 sq ft.
 Fertilize
generally at a rate of 5 pounds per 1000 sq ft. So, a 50 pound
bag is more than enough for a high school size infield. A little
league infield will take about 25 pounds. A typical high school outfield
will need 9 bags. A typical little league outfield will need 3
bags.
 Topdress
on the infield turf at a rate of 510 yards for a high school
size infield. A little league size infield will take 35
yards on the turf. Use less if the infield is in good shape and
level. Use more if the infield has ruts and low spots you are
leveling out. I used top dressing on a high school outfield once.
Once was enough. I used 40 tons which was not enough and I spent
most of two days spreading it. How much do I need? It can vary
quite a bit, but these guidelines generally work.
 Turface
on the infield skin and basepaths. Use two of the 50 pounds bags on
homeplate, the mound, and the basepaths. Cover a high school size
infield with 40 bags. Use a nail drag to work it in.
 Improving
warning track at a high school field. I used
8 yards of a mix that was 50% decomposed granite and 50% crushed red
lava rock.
 Adding
baseball mix to your infield skin. Depends somewhat on
how much you are missing, but a start is 10 yards on a high school size
field and 5 yards on a little league field.
Once
you've read through the answer your question how much do I need it's a
good idea to review the getting started section. 
50 lb bags
are the
most economical
