Great questions Kevin.

I'm in the initial process of building a sprayer to load onto my 3pt hitch
(9N Ford). So far I have the pto pump, 50 gallon plastic food-grade barrel,
some fittings and a prayer. I'm not a welder, yet. I'm curious what
others have done to build a sprayer. any ideas on how to construct one w/o
the use of a welder? I've been looking at my cultivator that's built
(rather nicely I might say) out of angle iron all bolted together. They did
a great job on it and it looks promising. But is it worth it?

Does anyone have any sprayer plans that they'd like to share? Pictures?

Thanks!

Mike

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 &quot;depth&quot; of water to an
acre<BR>
of <BR>
land involves enormous amounts of water.&nbsp; 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.&nbsp; 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.&nbsp; 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>

&gt; I am slightly embarrassed (but not really, cause I make mistakes a <BR>
lot) to have been eronious with data in my firstever letter to yall.<BR>
&gt; <BR>
&gt; The real numbers are (I asked a farmer; they know their stuff):<BR>
&gt; <BR>
&gt; 1 Acre inch = 27,154 gallons<BR>
&gt; <BR>
&gt; 1/8 Acre inch = 3400 gallons = .07805 / 1 sq. ft.<BR>
&gt; it seems impracticle to equip myself to bring this volume of water <BR>
with me.&nbsp; I think this volume would be extremely challenging for me<BR>
to <BR>
spray in a reasonable legnth of time to remain economically viable.<BR>
&gt; <BR>
&gt; My target application rate is 1 Acre per Hour.<BR>
&gt; <BR>
&gt; 1/32 Acre inch = 850 gal = .01951 gal / 1 sq.ft. <BR>
&gt;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;
&nbsp;&nbsp;&nbsp; = 14.16 gpm flow (1 Hr) <BR>
&gt; 1/64 Acre inch = 425 gal = .00975 gal / 1 sq.ft. <BR>
&gt;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;
&nbsp;&nbsp;&nbsp; = 7.083 gpm flow (1Hr)<BR>
&gt; Application approximate to these ratios of volume to area seem more
<BR>
practicle.&nbsp; I believe I can configure to achieve a flow that fits my
<BR>
arbitrary yet critical criterion of time.&nbsp; <BR>
&gt; <BR>
&gt; Among the questions are:&nbsp; <BR>
&gt; Does application of compost tea at a ration of this volume of water
<BR>
support the water requirements of the microbes?&nbsp; Will the application
<BR>
result in desired effects?&nbsp; Is the volume great enough to be <BR>
considered a root drench?&nbsp; Would supplemental watering be necessary,
<BR>
immediately?<BR>
&gt; <BR>
&gt; Or is there equipment available (configurations) capable of putting
<BR>
down more water (gpm) during application?&nbsp; <BR>
&gt; <BR>
&gt; Specifications to consider:<BR>
&gt; *It has been suggested to me that a diaphram pump has the gentlest,
<BR>
least violent action on the microbes.<BR>
&gt; <BR>
&gt; *The Brewing manual suggests 100 psi up to 600 psi is acceptable to
<BR>
transport microbes, yet microbes should contact surfaces at no more <BR>
than 20 - 80 psi.<BR>
&gt; <BR>
&gt; *Gallons Per Minute Flow<BR>
&gt; *Total water Volume per Acre<BR>
&gt; <BR>
&gt; I am attempting to configure a Compost Tea Spraying Truck (truck <BR>
specs: 2001 Chevy 2500 HD Duramax Diesel (454 cu.in., 6.0 turbo), <BR>
Alison 5 speed Transmission, 6.5 ft. box, 3200lbs. payload; 12000<BR>
lbs. <BR>
tow capacity) with Hand operated wand-type spraying as well as boom <BR>
operated spraying capabilities.&nbsp; <BR>
&gt; <BR>
&gt; Seems like a trailer may need to be considered to enter system <BR>
configurations to meet water demands.<BR>
&gt; <BR>
&gt; I would also like to explore possibilities of incorporating a <BR>
proportionate pump.<BR>
&gt; <BR>
&gt; Thank you for your time and consideration, everyone.<BR>
