I have read recent articles advising to spread nitrogen based products to help fertilise and green the lawn. Although I am careful to water afterwards I find that I am left with brown scorched marks throughout the lawn. Can you advise on what product to use which will green my lawn but avoid this damage. Can you also please explain what is sulphate of iron and what its used for.

If you are getting scorching after using lawn feed, you are applying it excessively and unevenly. Try to spread it as evenly as possible and only when rain is guaranteed on the way. Use a spreader if you have a large area.
Sulphate of iron is a salt, used for moss control , mixed with sand or water.
