Glen~
Thanks for responding. Good advice. I would like to set up and spray at will!, so I think I will be investing in a 325 gal tank (best I can match to my payload and remain trailerless; although the decision is also based on current local availability ), spray at about 5 gpm (to get an acre out of my dilution and meet percieved time requirements), which will determine the legnth of my necessary spray bredth.
Now if I could decide on a diaphram pump, engine and air compressor (does one necessarily need air compression to drive a diaphram) that will allow me to dial in flow, psi, and gpm, I would be getting somewhere! maybe? By the way it would be awesome to configure a system which will be compatible with a behind the cab style boom!
What type of equipment do you use to spray?
ciao~ kev

Kevin-maybe I can give my 1 cents worth on soil drenching.<BR>
<BR>
As you pointed out, adding a reasonable "depth" of water to an acre<BR>
of <BR>
land involves enormous amounts of water. And yes, this water should <BR>
be dechlorinated from what everyone has shared on this list.<BR>
<BR>
My tiny bit of experience this year has led me personally to use our <BR>
spring rains to soak in these soil drenches, rather than trying to<BR>
add <BR>
enough carrier water to move the AACT into the root zone.<BR>
<BR>
By watching the weather forecast, along with the very wet spring we <BR>
have had in the Pacific Northwest (south of you tho!) I've been able <BR>
to drench soil and nursery containers prior to or during 1/2 to 1 in. <BR>
rainfall events here. So much faster and more effective than trying <BR>
to provide those thousands of gallons of dechlorinated water myself.<BR>
<BR>
I'm just not sure I'd try to duplicate that now that the substantial <BR>
rains are done till fall...just plan on doing all the soil drench <BR>
during the spring or after fall rains have started.<BR>
<BR>
This isn't applicable to other areas with quite different weather <BR>
patterns, but wonder what others in the wet coast applying tea think <BR>
of my take on this.<BR>
<BR>
And thanks Kevin for bringing this subject up. An acre inch is that <BR>
much water...I know I'll never be able to apply that economically and <BR>
get paid enough to do it!<BR>
