Note theres 2 pics of soil report.
42,069 sq ft yard area
(0.97 acre yard, in rural area- surrounded by weedy pastureland so my yard is weedy as well)
I just had the yard sprayed 2 days ago (dormant hybrid+common burmuda) with 41% glyphosate diluted to 16oz/acre. Waiting for the abundance of weeds to die and burmuda to green up before proceeding to next step.
My math-
Spring:
126,000 lbs triple superphosphate 0-46-0
(3lb/1000sq ft)
And
252,000 lbs 15-0-15 fertilizer
(6 lb/1000sq ft)
July
252,099 lbs 16-4-8 fertilizer
(6 lb/sq ft)
Early Spring or Fall
Says to use recommended amt of limestone but I don’t see that recommendation on report?
Is my math correct? Are they seriously saying I need to buy/broadcast 252,000 pounds (!!!) of fertilizer plus 126,000 pounds (!!!) of triple superphosphate?
Plus limestone (I don’t see how much on the report, do you?).
I need a bigger truck. 🛻And muscles. 👵🏼
I’m a 74yo DIY granny on a budget, need your guidance please?

Rate is per 1000 sqft. So 42 x the recommended rate.
That report can’t be right…lol That’s an insane amount of any product to apply….
42069 sqft ÷ 1000 sq ft = 42.069 (1000sq ft plots). So if you need 3lbs per 1000 of triple phosphate you would apply 126 lbs total throughout your entire yard. (3lbs per 1000)
For 6lbs of nitrogen you would apply a total of 252 lbs of fertilizer throughout your total yard. (6lbs per 1000)
43k-yard area
3-lbs per k
129 lbs
Lime rates are based on soil test results.
Hope this helps 🙃
Divide your numbers by 1,000. So acre is about 44k square feet, times 3lbs per 1K and it’s 132
Limestone is on the package you buy. If you thought your fertilizer was a lot wait till you see the limestone recommendation for that much turf lol.
Also shout out to Clemson AG extension. Very helpful if you have questions.
Edit: lime is 20-50lbs per 1K sqft depending on the bag you get, Lowe’s sells a 40lb bag for $7.
Your math is doing something but it’s not mathing
42,000 sq ft yd. 3 lb per1000 sq ft
42×3=126
Your math was at a rate of 3 lb per 1sq ft
No, your math is definitely not matching! not sure how you got those numbers. hang loose you’re way too high by bc a factor of 1000x. Let me finish brunch and I’ll get back to this.
In short, 100 lb of triple super 0-46-0 has 46 lb of P2O5 in it. If you need 3lb per 1000, you need about 130 lb (43,000/1000 * 3) of P or 280 lb of triple super for the whole yard (130/46*100)
Farmers do 200 lb of triple super per acre for huge corn crops if that gives you an idea.
Hey, just wanted to let you know that your personal info is still VERY visible through that black mark you put over it
If I’m reading that note correctly below the results chart, they’ve got your yard measured at about 425,000,000 (425 MILLION) square feet. That’s…. a lot. About 9750 acres, give or take.
I’m going to assume there was some type of entry error there. You don’t need 125000 pounds of *anything* in a given year.
I’ll say their total amounts per 1000 sqft are reasonable, if on the higher end of normal. I’d say you could easily get good results with 1-2 lb of nitrogen per 1000 sqft per year. Their “high maintenance” package seems excessive, bordering on potentially harmful, depending on how they apply it/spread out applications.
Your best option may be to just focus on a 10k sqft section or two, spend a couple seasons figuring out what works best, and scale from there. The biggest mistake I ever made was trying to get everything perfect in one go. Great way to waste time and money right there.
You added a few extra zeros.
126 lbs of 0-46-0
252 lbs of 15-0-15
252 lbs of 16-4-8
For lime, I see 87 lbs per 1,000 sq ft. That’s a lot of lime, so split this into multiple applications over a few years.
I would focus on the pH this spring. You need a hell of a lot of lime to get the oh squared away. It’s saying you need 87lbs per 1000 ft which would be 3.5 tons of lime. Without the pH being more neutral, none of the other nutrients will be available to the plant.
No you’re looking at the wrong number. They are suggesting 3# of 0-46-0 per thosand sq ft. That’d be 3*42=126 pounds of 0-46-0. Y
6*42=252 pounds of 15-0-15 yielding ~ 1# n per 1000
6*42=252 pounds of 16-4-8 yielding ~ 1# n per 1000
A lot of literature says a good range of phos *UNlESS you are seeding/padding is around 20-40 range/acre. You don’t absolutely have to fix. So increasing it by 6pounds per acre should be easy. You could use a 13-13-13 product to increase both categories as well. (Instead of 0-46-0). You’d just be adding it more slowly this way
You multiplied the lbs/1,000 square foot by your total square footage, instead of doing 1,000 square foot intervals.
So your lawn is 42,069 square feet. Divide by 1,000 and you get 42.069 units of 1,000 square feet.
Starting with lime, which is directly above the comments section on the bottom of the report. Clemson is recommending 87 pounds per 1,000 square feet.
That would mean you need 3,660 pounds of lime (42.069 x 87) applied over the entire year. I wouldn’t recommend doing this all at once. I’d do one in the spring and another in the fall. Doing 50% each time, so half that amount (44 #/1,000 in the spring, 43 #/1,000 in the fall), making sure there is rain forecasted each time you go to apply.
With lime, you have to also consider the calcium carbonate equivalent (CCE), which will be listed on the label of your liming product. This is essentially the % of lime the product contains. Say your CCE = 80, that’s 80% of lime actually going down.
87 lbs/1,000 (from your soil report) divided by 0.80 (80/100 to get the decimal form of a %) = 108.75 lbs/1,000 of that liming product. The 80% is just an example, you get the exact number from the product label of whatever lime product you purchase.
You then would order that amount of product, and apply half of it each time. Does that make sense?
Next, for the recommendations. Comment 425 recommends:
– 3 lbs/1,000 of Triple Super Phosphate (0-46-0)
– 6 lbs/1,000 of 15-0-15 fertilizer
That would be 42.069 x 3 =126.207 lbs of 0-46-0 and 42.609 x 3 =127.827 of 15-0-15 applied in the spring.
Keep in mind that fertilizer numbers determine the %, just get as close as you can. So if you find 30-0-30, you would use half as much product because it’s twice the ratio of 15-0-15.
Next, in July, Clemson recommends:
– 6 lbs/1,000 square feet of 16-4-8, which would be 42.069 x 6 =252.414 lbs of 16-4-8 product.
You keep this same math going for any other applications they recommend.
With having an acre of lawn you’ll find this is a lot to keep up with. You don’t have to jump all in, you can just focus on an area immediately around your house. As you get into this hobby, you may also find that liquids that you apply with a sprayer may end up being cheaper than a granular product, but take a little more care in mixing, applying, and purchasing spraying equipment.
Alternatively, you can also divide the recommended rates by 1,000 and just multiply by the actual square footage:
3 lbs/1,000 =0.003 lbs/ square foot x 42,069 square feet = 126.207 lbs. it’s just a matter of preference, just write down your units and you’ll follow them through.
