Simple pH test

Lab seems to have lost my soil samples, need to crack on with work and need to know pH of block of land. Have a calibrated optical pH meter for checking water for the chooks and was thinking is it just a matter of mixing some soil samples with distilled water and checking for a simple farmgate pH test? Is this a thing? if so what amounts of water etc do I use?

Meter tend to be unreliable - simple kits from garden centres are the real thing in miniature and good enough for most practical purposes - £2-£3 each generally.

Just take some more and send them in the post, get results by email within 2-3 days. I would not trust a pH meter, they need to be perfectly cleaned and calibrated before each use anyway and I'd be loathe to plant or fertilise a crop without knowing the P or K indices as just as much as I'd be loathe to do the same without knowing the pH. There really are no shortcuts in this sort of thing.

Especially now with the cost of fert

Yes I understand that but the N, P, and K levels can be addressed as we go along but the pH correction with Lime has to be done now if the pH is even within range of the proposed crop. As I said at the start of the thread, was wanting to find out pH to let me away, labs are up to a two week turn around at the minute with covid staff issues and work load.

i have sampled some ground here the last few years, results through yara i think via local meal firm, ground is getting worse for ph was 5.6 last year and now 5.4, got egg shells. Found with gran lime that i noticed no difference but will test both again next year. lab results seem to vary alot no matter whaat you do so im going with a 3 test average. one place done three times and no lime spread has been 5.4, 6 and 5.8.

can anyone explain

I could explain why the granular lime didn’t work, but I don’t want to go on about it! 😉

The slight variations in pH over time could be because the soil samples were taken from slightly different places. There will always be variations even within a few yards of each other.

At those levels you may as well pee on said soil as put granular on , it needs a big hit not a slap

Does anyone use this tracking system for spreading lime , be interested in how much variation there is in a field ?? Sorry to detract
I’m guessing you’re talking about Terramap? We had some fields done last autumn, very interesting seeing the results. Huge potential for varying rates of all sorts of inputs, but I wanted to start with it because I’ve never had much faith in taking conventional soil samples can give you a proper idea of your fields, it’s very much lick finger and stick it in the air in comparison. Pleasantly surprised at ph of our fields as we haven’t used much lime historically.

Oh I don't think I will be gran lime much. Hence why I tried egg shells but I will sample the patches in a next year too.

Small differences like those quoted I wouldn't make too much noise about- could be down to your sampling alone. Granular lime is a complete waste of time in your scenario- get and buy actual ground lime and put on 2 tonne/acre. pH 5.4 is chuffing low.

Restivted by close by houses but looking into the band type auger spreaders. Just need enough of small fields or a group of local farmers maybe to leave it worth while for the contractor
