How to make grass lushy green color?

No, wishing to be a party-pooper, but I imagine that a very significant amount of this artificial fertiliser ends up in our surface water, contributing to the enrichment and eutrophication of our inland waterways. If you are not in a coastal region, the impact is obviously greater, as our fresh water has a more limited ability to absorb this enrichment.

I concede the argument in favour of fertiliser in terms of bringing a lawn from inadequate to adequate, but once your lawn is adequate I think you should stop: we should all bear in mind that these products have consequences for the environment.
 
Mob,
Decent point you;ve raised, however it's more relevant to intensive farmers who spread maybe 20 or 30 tonnes of fertiliser per year on their farm than to a householder spreading a couple of kilos of fertiliser on their lawn once a year.
The quality of our waterways is certainly a cause for concern and we all need to act responsibly. (Co. Councils included!)
 


Matter of interest is there a dog in the area using the lawn as a loo?
I had this problem with the neighbours dog not so long ago and I had dead patches of lawn, I invested in a set of gates and this sloved the problem.
 
Can anyone advise if using any of the suggestions above on a new lawn would cause harm to new grass (aprox. 6 months set) ?
