Most combination lawn feeds (with weedkiller / mosskiller) are Urea based materials. These products are reliant on water to start the process of feeding and weeding etc. If there is too much water the breakdown is too quick and can end up being washed away. Too little water and it will automatically burn the grass. This is similar to dogs urine (urea) that will have a similar effect.
