I have a lawn I'm renovating today. The soil test showed the ground was basically barren across the board and just very slightly alkiline as far as PH goes. I've never ran into this before.

My question is what is the maximum rate (lbs per 1,000) of fertilize you would feel comfortable adding in this situation at planting? Since I know someone will probably ask, it's fescue seed and the highs are only getting around 60 degrees.

I'll check back before applying the fertilize.

THANKS

Without knowing what you are using hard to tell.

I am using 25-10-10 40% scu 4%FE. 3.75 #M

Now since you are seeding, 18-24-12 is good at 4#M

LGF,

Thanks for atleast trying to help. I've never worked with "completely dead" soil before. So this was a new one on me.

As for the fertilize used...ever hear of Royster Clark? It was triple 17. Tell me how many lbs you would have put down and maybe...just maybe I'll tell you what I did:D

3.5 to 4 pounds per 1000, depends on how green the grass is that is already there.

I don't know how you compute yours but I was taught to break it down in terms of lbs of N-P-K per 1,000 sq ft. For example roughly 3 lbs of triple 17 will deliver roughly 1 lb of N-P-K per 1,000 sq ft.

As for the current grass, it "was" common bermuda (wire grass) and it was already going dormant. That crap will survive anything but cold and I've just proved it!

Back to the fertilize...I was more aggressive than that. That's all I'll say for now! ;)

17% of 3lbs is only 1/2 lb of each.

If the soil is as low as it sounds it was (no values posted) my next question would be what % slow release was that fert? I've never heard of it. Had to be close to an all chem because coatings way something & that something brings down the analysis.

We also don't know the CEC, but it said "DEAD". I've not seen that on a soil test either. LOL

Either way, you'd get away with 10lbs/M.
Thats still only 1.7lbs of each element. Not great, but probably not lethal either.

tremor,
I meant 1/2.

I have been taught that you divide 100 by the number on the bag to find out how much of it to apply to get 1 lb of say N. So in 17-17-17 it would take 5.88 lbs to get 1 lb of each or almost 3 lb to get 1/2 lb of each.

There is no slow release N in this product and I generally don't use it. Personally, I like 10-20-20 for starter fertilize. I just decided to hit it with more N than I usually use.

17-17-17 will cover 8,500 sq. ft at 1 lb. of N,P,&K per 1000 sq. ft. :) ;) :) ED

Cutting the first number in half works only if the fertilizer is packed in a 50 lb. bag. For all other sizes we're better of with the formula.

Desired pounds of N (1) divided by the decimal analysis or 17 divided by 100 (.17) = 5.88 lbs/1000 sq. ft.
Then if the material was packed 40lbs per bag:
40 divided by 5.88 = 6.802 times 100 = 6800 sq ft

Envy, What rate did you decide to use?

Spyker has a good calculator on their website:

I put out not quite 10 lbs per 1,000 sq ft. That's 1.7 lbs of each as stated above. I've never applied more than 1 lb of N per 1,000.

I might have fried it :blush:

But, I don't think it will hurt really. The weather is cool and damp. I guess I'll see soon enough!
