View Full Version : High Lime requirement

I have a lime requirement of 140lbs/K. I am in Pa, so I used Penn State's soil lab. They recommend splitting the applications in two,(70lbs/k) the yard is 20K

What are you guys paying for dolomitic lime? I got a quote for $6.00 a bag, I believe it was 50lbs bag. 140lbs/1000 * 20000 = 2800lbs.
2800lbs/50lbs = 56bags

56 bags * $6.00 = $336 just for the material. Does this seem high? Obviously I'm trying to use this to price out the job.

Price sounds about right but thats a lot of product to put down in 2 apps. Maybe split into 4?

Any more than 50lbs per k per application really does not provide any more benefit. Price is not to far off.

Look into solu-cal, it is more expensive but you only need 20% of the material to acheive the same results.

Athletic field, what was the soil reading on Mg, you may be raising the Mg too high with the dolomitic lime, depending on the reading you may want to move to calacitic lime

Mg is .74meq/100g of soil and

Mg 6.3% saturation of the CEC
Ca 26.6% saturation of CEC
K 3.5% saturation of CEC
remander acidity (H)

Wow, That is the Lowest Ca/Mg Base sat % I have ever seen in over 25 years.

2 season Project IMO.

Dol Lime 1st season 50 lbs Split 2x....50 Now and 50 Oct 1st. (the price is good)

Retest March 09, and determine if you finish up with the Hi-Cal Lime.

What is the soil type? Loam has a different requirement than sandy for a desired pH shift.

Thanks Pete

What mark up do you guys use for lime?

Same price as any other application. Maybe discount a little.

Gorknoids - Yes loam soils take more lime to change the pH compared to sandy soils. That is called the buffer pH or acidity on the soil. The pH you can test at home is the soil water or soil solution pH. You can get the same pH for a loamy or sandy soil, but the Cation exchange of loamy soils is greater than sand. Therefore a higher lime requirment is needed to exchange the acidity (H+) on the soil. The soil lab bases lime requirments on buffer pH or acidity on the soil.

Welcome AF.

I do Cost Plus. So I give a price knowing how long it will take + Materials (add 15% handling fee) + Stop Fee.

I cannot say my "Rate", but I can say it was worked out with an Accountant and My Wife who has a degree in Economics :)


Quality Cost More.
