You might need to double check my math, not as bad as I expected.

Pre-E: Prodiamine $65 for 5lb
$.65/1k Annually
$0.5/1K Monthly
Year total for 3k of lawn is $1.95

Post-E: Celsius $116 for 10oz - Haven't needed to apply (in my lawn) for 2 seasons.
$0.0/1k Annually
$0.0/1K Monthly
Year total for 3k of lawn is $0.00

Fert: Milorganite $13 for 36lb (Got on sale for $3 last season)
$32.62/1k Annually ($7/1k on sale)
$4.66/1k Monthly ($1/1k on sale)
Year total for 3k of lawn is $97.86 ($21 on sale)

PGR: T-Pac $75 for 1 Quart
$8.75/1k Annually
$1.25/1k Monthly
Year total for 3k of lawn is $26.25

In the end, $126.06 for this season in lawn chemicals.

I don't keep track of Gas or Water.

Penterra was only used a couple times, then a friend purchased the remaining amount.

I plan to try some other soil surfactants, so I'll need to add that to the total!
