Fair point Richard. This is a possibility and rectifying the pH would be far cheaper than replacing the soil. When you mention limeing it, do you mean add limestone chippings or dust etc???

be sure to get garden lime as a powder from a proper garden shop. NOT builders lime. slight amounts and read the safety instructions. Hope it is that simple.

The problem with testing is that the chemical is only released when the plant matter in the manure breaks down and so you could test and everything appear to be OK and then have problems at a later date.

Last year our tomatoes were fine for a month or two and then succumbed to the poisoning. Also the problem can be very localised meaning the plants growing right alongside one another may be affected or not.

I've posted everything anyone has told me about this problem on my website.

It may not be weedkiller in your compost, because I can see, in your photos weeds growing. Also the bottom leaves look unaffected its only the top new leaves that are curling.

Frost damage ?
Scorching ?

Last year our runner beans were badly affected but weeds grew alongside the plants perfectly well.

The problem seemed to be that the levels of herbicide residue is likely to be very low but some plants are particularly susceptible namely the potato family and peas and beans. To kill the weeds the amount of herbicide just wouldn't be enough.

Sorry I shouldn't have posted my web link - didn't mean to break the rules - just trying to help.

If you wish to read up what I have found out about the problem then my web site link is attached to my profile and the link to the manure problem is at the top of the home page.

Hope that this is OK - if not sorry again.
