have any of you guys used the lime that comes from the city water plants. One of the custom spreading guys here sells it/uses it all the time. He says it tests better than the local field lime. Is it good for more than 1 or 2 years? He can get all he needs from the Capitol City water plant. We gotta spread 2 ton/acre on moms farm this fall. It will not be worked in just spread on top. Thanks guys.

the stuff you use in the field is called " garden lime"... the stuff at the water plant is "hydrated lime"... yes, it can be used..

Liming materials

Lime raises pH and is usually added as ground limestone, commonly called ‘garden lime’. The active ingredient is calcium carbonate. Ground limestone is easy to spread, widely offered in garden centres, and is the recommended liming material for gardeners. Calcified seaweed and ground chalk are other forms of calcium carbonate offered to gardeners.

Ground magnesian limestone, often called ‘Dolomite lime’ is a ground limestone rich is magnesium carbonate as well as calcium carbonate and is used to lime soils that lack magnesium (see our page on  https://www.rhs.org.uk/advice/profile?pid=450" rel="nofollow - plant nutrition  for more information on plant nutrients).

Hydrated lime (calcium hydroxide), sold for use by builders, can also be used. It is a fine powder, quick acting, but can irritate skin and eyes if not handled carefully.

The effectiveness (called the ‘Neutralising Value’ (NV)) is expressed as a percentage of the neutralising value of pure calcium oxide (which is caustic so cannot be used). The NV varies between materials – typical examples include:

  • Ground Limestone (garden lime)  – NV 50-55
  • Ground Chalk – NV 50-55
  • Ground Magnesian Limestone (Dolodust) – NV 56
  • Calcified Seaweed – NV 44
  • Hydrated Lime – NV 70

Therefore, if you use hydrated lime, you will need much less than products containing calcium carbonate.

Liming materials are very finely ground s

Some have used Lime from City Water Treatment Plants around here. It does not spread evenly and leaves large lumps as it is still wet and they use a manure spreader to spread it as it won't spread from a conventional lime spreader. I have been told it does not become available in the soil as fast as as ag lime. It is cheaper though.

The lime from the water plants around here is mixed with the sludge removed from the treated sewage to make clean "city water"

If it was fun to pull in LOW gear, I could have a John Deere.
Real pullers don't have speed limits.
If you can't make it GO... make it SHINY

Sounds similar to the lime we can get from sugar processing???  It is not as "strong", and spreads like chunks of wet gumbo clay.  It's a PITA.  But "cheaper". 

Dolomitic lime is what we get here readily.  Huge quarry in Rogers City, MI.

It all goes as sewage sludge here and you can only put on the same field for 3 years then gotta wait 6 or 10 years before using it on that field again ------ NASTY chit to be around.
a guy down the road here gets money for allowing Bloomington to dump it on his farm. Smells worse than hog barns!

Sewage sludge needs to be watched for heavy metal content, that can poison your land for a really long time.

The water here is high in lime. The citys runs the drinking water thru a huge water softener removing the lime. I see huge piles of it outside the water treatment plants. Is this the same stuff you guys are calling sewage lime?

Every quarry around here has lime fines from crushing stone, HOWEVER one in particular at Antire Quarry runs their lime thru sieves to parcel out rough lime and Ultra Fine Lime as a powder form,  Very dry the stuff flows like liquid.   Have had our place done with that and our soils tests came back great just two months after first application.

What is metal sludge?
Sewage sludge is a byproduct of domestic sewage and waste water treatment. ... Concentrations of up to 10 heavy metals (As, Cr, Cd, Cu, Pb, Hg, Mo, Ni, Se and Zn) are typically monitored in sewage sludge. When maximum permissible concentrations are not met, sludge is mainly disposed of by incineration.
