ph testing

Whenever the subject of soil pH testing has been discussed in these forums the consensus is usually that the "pH probe meter" type tend to be very inaccurate and erratic - the chemical ones are quite cheap, albeit more faff, especially as you need to take a sample from more than one place to get a good "average" reading for your soil.

You will want to test to find the average of each area you may want to lime, maybe a bed or each part of your rotation for exanple.

Take a trowell and take lots of samples all over the chosen area going down the full trowell depth. Put these in a bucket and mix them together thoroughly. Test the mixed up soil several times. The results should all give the same answer, give or take a bit.

Overliming can be as bad as allowing soil to become acid.

I bought a cheap one from e-bay and never got around to using it just as the plot was so over grown with weeds there had to some goodness in the soil - I will test for interest alone - my problem is I have a tub of Chicken poop pellets and BFB but if I use them I will just drive the foxes bonkers and they will rip my plot apart more than usual.
