if those dumbells in charge had given it 6 months to restabalize it would have been fine.
Sorry Stan that would have never happened.
I've well documented here what they did wrong (and I'm only watching from 1000kms away on TV) but they were stuffed once they continued on the maintenance program that was part of the contract, the only way out was to rip off the top of the track to rid the track of the organic layer they had created.
I have no reason to believe the track wasn't constructed properly and being sand based is fine if treated correctly but you can not use the same maintenance practices on sand based tracks that you have for the last 40 years
on the original or conventional loam type surfaces.
Think of it like this, you have a virgin sand that is basically inert, no microflora or any of the goodies that help the profile cycle and break down organic matter but what do they do? They stick 1 tonne / ha of chicken manure fines every month over the damn thing
(as per the program from the contractor) this creates a black pudgy layer that simply can not break down. This created an organic layer on the surface that capped the sand, this just promotes disease, weakening the plant, insect attack etc all while moisture can't move through so to compound it the roots wouldn't & didn't need to go deeper (all the moisture is stuck at the top remember) so it was like racing on a big pudgy sponge that the horses just tore out as there was no root development
