Can you help with interpreting this soil test?

Test came back and said Lime---40M, then nitrogen 20lbs of 5-10-10 or equiv/1000 sqft.

Does that mean 40lbs lime /1000 sq ft?

And for the fert can I use a 10-20-20 or a 15-30-30?

I tried calling but couldn't get anyone

Thanks!

How about telling us the lbs per acre of phos and potassium, and also the pH, the cation exchange capacity and soil texture. How many applications per year? Irrigated? Returning clippings?
What type of grass? Low maintenance lawn, putting green or baseball field? Or is this a general recommendation that also covers peanuts, cotton and tobacco? Show the whole test or at least full data--the soil experts would love to help you then.

5-10-10 ? I never saw that analysis before. Waste of money.
Not legal in Michigan, Minnesota, Wisconsin and others--or near Chesapeake Bay, phosphorus outlawed in many areas.

What lab did the test? Who did the recommendations?
Does you local dealer agree or disagree?

Soil Class--MIN
HM%--.27
W/V--1.02
CEC--6.2
BS%--71
Ac--1.8
pH--5.5
P-I--10
K-I--49
Ca%--49
Mg%--17
Mn-I--151
ZN-I--52
ZN-AI--52
Cu-I--112
S-I--87
Na--.2

That's all it says.

Its the lawn I posted about regarding the discoloring a few months ago.

I do not understand some of the terms.
My own soil is CEC 5.9, and Phos is 17, pH is 6.8. My grass looks fine. Irrigated, sandy, low natural fertility.
You need lime, but centipede is OK with acid soil. Slow-release nitrogen is the main product you should be thinking about. Beyond that I will let the real soil scientists add some truly expert advice.

The grass looks fine...
The reason for the soil test is what??

What is the good number for CEC ratings?(Is 5.9 considered above? or below? the desired standard?)

CEC ranges from 2 to 25meq, with 2 representing a rather infertile sandy soils, so I'd be pushing for 10-15, wouldn't I???

Thanks for the link...

I like what it said about holding nutrients in reserve which of course relate directly to fertility of the soil and fertilizer applications... CEC is rather important... Correct???

Typical CEC values around here are about 10 on sandy soils and about 16 on clay soils.

"A high CEC is desirable because nutrients are
less subject to leaching and adequate quantities
of nutrient reserves can be maintained..."


You definately got better soils around there than we do here... How does your soils compare to Illinios plains??

CEC can be much higher than 25 meq
