Soil Sample Results

jfh

i would really appreciate a bit of help with some results. first time taking soil samples & got them done through the Co-Op who also sell the fertilizer so would like to get an opinion of boards.ie crew..

firstly how little lime is too low?
most fields require a tonne to bring it up to 6.5 PH
one reseeded field requires 2 tonne,
is that substantially low? worth doing?
results say PH(water) 5.6
PH(buffer) 6.3

if so should i go with ground lime, understand gran lime is easier to spread but only lasts for one year & is more expensive, if i had to do a few fields i'll try to go with the ground stuff.

The main silage field is very low on Potassium, 36mg/l

the reseeded field is very low on Phosphorus 1.7 mg/l

now for the questions,
1)would a good spread of slurry fix those?
2)what fertilizer should i be getting?

any feedback welcome

Slurry will help, but you probably need 2 bags 0 7 30 per acre on the silage ground as well. The lime will help make more nutrients available for plants, but I'm not sure if you should spread it over 2 years or if you can put it all out in one go. What sort of soil have you?

well blue5000 the land is free draining, not as good as tipperary land:D

would i not need a compound with N for the silage ground?

would i get away with just slurry & Urea

My guess is that's what you have been doing all along:pac: Any harm to ask were you in reps for a while?
I could be wrong on this but AFAIK first cut of silage removes something like 150 units of potash, that's 5 bags of 0 7 30, 1000 gals of slurry is roughly the same as 1 bag of 0 7 30 for P and K, so by my -reckoning (if I'm right at 150 units) you'd need about 5000 gals of slurry per acre.

Sorry I'm wrong it's 100 units /ac for grass, think it's maize removes 150 units. have a look at link, 3000 gal slurry.

At ph of 5.6, you're getting a very poor response to your fertiliser, you need a ph of 6,5 to get soil/ grass right,
As for fertiliser recommendations, it depend what stocking rate you want, Probably need 3000gls/acre good slurry +3 bags 24 - 5 - 10 to be fair to the land and get a good crop,
lime should be a priority

right thanks rangler1, will get on the Lime.

you recommend ground lime over granulated?

jfh

lads, would i be too late to spread lime now?
just on grazing ground, wouldn't go near silage field

I spread 2ton/ac on 5.6ph land in feb last year and ph was 6.5 in November
2ton ground lime/acre will last 4-5 years.
100kg granulated lime/ac will last about a year to eighteen months.
You can do the figures yourself

When would be too late to apply ground lime to meadows?
Was thinking slurry in March followed by lime, currently being grazed by Ewe&Lamb

Appreciate the advice, I was going with ground lime myself

Great mind think alike !!! I put 2t/acre out on silage ground after 2nd cut last august and would be delighted to be at 6.5. Thought I read somewhere that it takes two years before the lime is reflected in soil test, but I bought one of these http://www.woodiesdiy.com/product/mini-ph-tester/25354/4.33#.VNIczk10y70

and will be testing the ground before I put out bagstuff the year. Would be happy if I got to 6.5 and lasted 4-5 years.

With rquirement for 1.5T/hec - 0.6T acre would ye still go groundlime or would a oroduct like growmax gran lime be as good?

Also all P+K in index 2, without the benifit of dung/slurry what sort of p+k should be spread this year tobring p+k up while still replacing grazing nutrients as well?

Intensive silage removes 1t of lime per yr.
You won't get pH to stay at 6.5 for 4-5 yrs

Just clicked on the link for that tester you bought on the description is says 8 tests in total? is that 8 different types of test or is it a disposable thing thats no use after 8 turns?
how accurate would you reckon it its?

It will do 8 separate PH tests, then bin it.

Alright it was 6.2 after 5yrs the last time, left it another 4 years and it wqs 5.6, would you bother going with 1 ton/ac....took nine years from 6.5 to 5.6

Is there anyone using a ton/year here, Ihave some land that doesn't seem to need any lime

Did you know that a 'Good Bullock Removes 25Kg of Lime every year'. :rolleyes:

I sampleled a field in mid april and am ready to put out lime now , it got 3000 gallons slurry to acre about 10 days a go. the results were;
PH= (Water) 5.3 (Buffer) 5.9. it says my lime requirement is 10 ton per hectare. i heard somewhere that you should only put out max 2 ton /acre in one go. index 2 for potassium and index 3 for phosphorus thats before the slurry

Yea 2T/ac max per year but you can do same next year too, which would be 10T/Ha.
Should leave 1 week after slurry application before spreading Lime
