To sub soil grass now or not

[Cab-over Pete]

The newsletters are rather vague on its make up . The best I can find is from a 2014 newsletter. It’s 66 % calcium lime. That’ll help the ph. The rest is “ a blend of essential products formulated to provide all the minerals your stock needs . “
Guess the remainder is slag n salt !
It does sound like the latest black magic cure all tonic , but the mineral status of my grass n silage have improved no end . And as they say it helps keep the ph topped up!
The boy who spreads it for me hates the damn stuff as it is a slow job for him spreading it at 5 or 6 cwt. He’s always got plenty other places to go, and finds it a right ball ache !

I just think if you bought lime slag or salt it would be less than half the price.

Anyway, going off topic a bit. Sorry.

Couldn't have said it better myself
Have done a bit in the spring due to time availability and it was just as you said - slits opened up, grass browned off.. seemed to stress the grass more and flip it into repro- mode too.
Autumn is the time IMO.

done some here in autrum worked OK but coming out of a dry summer hard as hell pulling and soil cracked in to blocks
stuff late spring worked better some die back of grass but acted like spray topping and grass kicked off again leafy

Following on from this discussion I’ve gone and hired a sumo gls later in the week hopefully it won’t rain to much tomorrow and make it too greasy

Watch this space for outcomes

I don't know the right time but the worst time is right before a serious dry spell. If you damage the roots the grass can die in a big way.
