    I have just recieved the results from my soil tests and I am confused by the reccomendations.The folowing are the results and reccomendations for one of my customers.The results are lbs per acre.P=36 low,K=234 adequate,Mg=171 high,calcium 3194 very high,soil pH 5.8,buffer pH 7.65,Zn 5.3 adequate,Fe=63 very high.The lab reccomended 2000lbs lime/acre, 400 lbs N/acre, 100 lbs P/acre,170 lbs K/acre.I may be misunderstanding the reccomendations ,but I think this equates to about 47 lbs lime per 1K,9 lbs N per 1K,2 lbs P per 1K,and 4lbs K per 1K to be applied over the course of a year.This seems way too much lime and N.:confused:

    Yeah, something is wrong. 9 lbs N/K! Can you post the report itself?

    The lime is about right as many don't put near enough down. The N seems like it should be 40lbs per acre, somewhere under a lb per 1k. Wonder if it is a typo.

    Maybe that is the reco for a corn contest grower. Or high yield cotton. We consider phos under 20 lbs per acre as deficient. But around our lakes we like the phos low. Even at 14 lbs per acre (one of my customers) the grass does fine. Nitrogen shoud be based on a nearby university turf agronomist suggestion. Probably about 4 pounds per thousand per year, 174 lbs per acre. Depends on turf type, irrigation, and use (baseball field, golf, homelawn?).

    the lime is correct.we have many lawns where the recommended lime is 50 lbs per thousand. some time we have to break it up into two or three applications of 50 lbs per k

    Lime is about right. Perhaps the N is really 0.9lbs/1000 instead of 9?
