Don't apply lime unless you have a soil test that tells you how much to apply. Magical is a fast acting lime so it reacts quicker than regular lime. However, the effect is short lived. If you have a certain amount of acidity, it takes a certain amount of lime (which will vary depending on how much your soil is buffered) to raise the pH and keep it there. It doesn't matter if it's fast acting or regular; you need whatever amount the soil test recommendations say. Regular lime will react over a period of about three years, some of it in a few weeks, some in a few months, some later. You can use up to 50 lb of regular lime per 1000 sq ft in an application, which are best done twice a year in fall and spring. For fast acting lime follow the directions on the bag. You are much more limited in how much you can apply at a time.

I did a cost comparison between Mag I Cal and lime from the Co-Op. the Co-Op price was much better. It was such a dramatic difference it made the decision for me.

Yes, you need 50 lb of lime per 1000 sq ft. Dolomitic lime will give you both calcium and magnesium in addition to raising the pH.

Is the Mag i Cal and other "fast" acting lines missing Magnesium?

Cost about the same but I spread 1 or 2 bags of Mag i cal vs 22 bags of "regular" like

I spread 25 bags 2020 to get the like up , looks like I need another 22-25 bags to get up to that 6.4 6.7 zone?

 

For 18000 sq ft, you need 900 lb of lime. With regular lime you can apply it all at one time. With the fast acting lime, you cannot apply it all at once. It's much more limited and would probably take you several years of twice yearly applications. Either way, you need 900 lb of lime. As for whether it contains calcium and magnesium or just calcium, read the label.

 

If you don't think the soil test is correct, you could retest. U of Massachusetts does soil tests. Be sure to follow the instructions on number of samples to take and mix up, the depth each of the samples should be, etc. What are doing about your potassium? Sulfate of potassium (0-0-50) would be a good thing to use.

Yup 900 lbs 25 bags 40lbs is 1000
22-25 bags or so.

Im waiting on results from Umass.
They are 6-10 business days. They received my test on 7/21 so only 4 business days in

Im trying to find K locally.
I called the closest farm supply place and the young girl was very honest and said she has no idea what I want or if they have it and theres only 2 orher kids here today loading hay and wood chips. I will have to call today.

 

If you spread 25 bags of lime in 2020, I would wait to spread any more. It takes 3 years for all that lime to show. 5.2 on a mysoil test in 2021 and 5.9 on a waypoint test in 2022 is exactly what i would expect to see. next year it will probably test 6.2 to 6.5. TTTF is good at that PH.

I agree. There isn't any rush to add lime. Va Tech asks for info on when the last lime application was and how much was applied and gives a lime credit for applications within the last 18 months. No credit for applications earlier than that. So I expect most of the lime two years ago has reacted. There is still some to go but likely a relatively small amount. Let's see what U Mass has to say. Late fall is a good time to apply lime. Then you should be set for the next few years.

Thank you , lets hope so , im getting tired just thinking of another 25 bag load of lime.
Now to just get some K in bulk!
SiteOne 2 hour round trip for a 50lb bag if 0-0-50 @ $96 ugh.

 

Finally found it,
I put a bag of this down back in april

Umass test just in

 

Here's 50 lb for $46 with probably shipping of around $30.

You could also check out 0-0-60 at nearby places. There are also fertilizers with nitrogen and a good amount of potassium, no phosphorus. I got some last year at Southern States that was 10-0-20. They were out of SOP. You could also check for SulPoMag or KMag.

 

Just seeing U Mass results. They say you need phosphorus. In that case, you could balanced fertilizer, like 10-10-10, which should be easy to find. That will give you all three nutrients.

The two labs are using different extractants so you can't compare numbers.

 

Go with calcitic lime when you do the lime. They make regular calcitic lime as well as the fast acting kind. UMass is saying your magnesium is high so avoid that. Waypoint had it in a medium category.

prill size is large but worked for me.

 

Maclawn applied "I applied 1000lbs Dolomitic lime over 18,000 sqft fall ***2021***" AND THEN 100 LBS of a fast acting lime in spring 2022.

 

When he put down the 1000 lb (in 2020 or 2021), his pH was 5.2, right? The application was around 50 lb per 1000 sq ft. But what was the lime recommendation then? If he had a MySoil test, it doesn't do a buffer pH and doesn't give a total lime recommendation. It may be that he needed 100 lb or 150 lb per 1000 sq ft, which would have entailed more than just one 50 lb per 1000 sq ft application. I think late fall will be a good time for another 50 lb per 1000 sq ft application. Waypoint is recommending 50 lb per 1000 sq ft, U Mass is recommending 100 lb per 1000 sq ft. (in two applications). 5.9 or 5.8 is an acceptable pH so it's ok to not do anything. But the target pH of 6.5 is better and another application will at least keep it from dropping from the 5.8 level.

In the future, one soil test a year is sufficient. And once levels are good, a test every three years is all you need. Use the same lab and take samples at about the same time of year. pH is generally higher in the spring than the summer. You can compare year to year if there is some consistency in when you test and use the same lab.

 

5.8ph is fine for turf type tall fescue. What's the problem?

Thanks Im working on more consistent ways.
I only used 2 different companies to compare.
Im not sure if there are better tests out there.
Im going to apply like soon

 

5.8ph is fine for turf type tall fescue. What's the problem?

My only concern is it dropping. I would like to at least get it up over 6
Im going to do 1000lbs over 18k ft2
This fall maybe sooner. Depends on the lime availability

Are u spreading this out granularly? Or are you using it as water soluble in a sprayer?
