"Dear Doug:

After talking to you at the Canadian Farm Show Toronto and much thinking, I purchased one of your Little River Pond Mill® circulators and had it installed on our hog manure lagoon.

Our lagoon, which we pump most of the liquid manure produced from our 110 sow farrow-to-finish operation, measures 105 ft. x 80 ft. with tapered sides and is about 13 ft. deep.  In the past when we went to irrigate out of this lagoon, we had to use a tractor driven agitator which would need to be run for about three or four days to attempt to agitate this pit up and usually we could not get the bottom five to six feet out of it because it was still to thick.

Last October, after crop harvest, we started pumping out of this lagoon on which the mill had been running since August, and we were, to put it mildly, "dumbfounded".  The first thing we noticed was that there was no odour from the lagoon, and the liquid was a different consistency.  We didn't use any agitation and it was just like pumping water, which is much more pleasurable than pumping manure.  I even got sprayed with the stuff, and it just dried off my clothes like rainwater, and there was no odour remaining.

We can see several other benefits to this mill - when we had a spill where the irrigator stalled out - if this had been the previous hog manure it would have laid on the ground as sludge, but this stuff just disappeared like rainwater.

This winter the lagoon was about half full, and when I walked out on the ice with a piece of pipe and broke a hole in the ice around the mill, stuck the pipe down into the liquid manure, it appears there was no sediment or solid thick manure remaining on the bottom.  At the same time I took a sample of the manure and I am including the results of this test with my letter.  We had it tested because one would think there was no value left in this manure when it changed to its current consistency, but as the test shows it has 13.4 lbs. of nitrogen, 2.6 lbs. of phosphorous, and 13 lbs. of potash.  We intend to irrigate this on our winter wheat this spring and it should save us considerable costs on our fertilizer." (See the graph below for cost savings)

"I feel this pond mill is one of the best investments a farmer could make if he has a manure lagoon - it eliminates the odour, the manure is much more pleasant to work with (just like water), and the biggest payback could be in the fact that one doesn't have to mechanically agitate the manure.

Yours truly,
Lloyd and Ken Smith"

When you take into consideration the fuel savings (because agitating can be eliminated), the reduced wear and tear on other farm equipment, and the savings in labour cost, the Little River Pond Mill® circulator pays for itself in a relatively short period of time.  Also, obnoxious odours can be eliminated, which is difficult to put a price on!

Lagoon Size:  105 ft. x 80 ft. x 13 ft.
Extra amount of liquid pumped out:  5 ft. x 97 ft. x 72 ft. = 218,250 gallons
 
Fertilizer value of 218,250 gallons:
Nitrogen = 13.4 lbs./1000 gallons = 1.327 metric tonnes * $352/tonne  = $467.10
Phosphorous = 2.6 lbs./1000 gallons = 0.257 metric tonnes * $335/tonne = $86.10
Potassium = 13.0 lbs./1000 gallons = 1.287 metric tonnes * $214/tonne = $275.42
Total = $828.62
Number of times/yr. lagoon is pumped out = * 2 times/yr.
Annual Fertilizer Savings = $1,657.24
