Ooops I've bought a lot

I've been out today and bought some blood, fish & bone meal when I say a lot I mean a lot 60kg in total (sale) 6 by 10kg tubs OK I bought the lidded tubs so I can make soup/tea/feed next year

Can I use this as lawn fertilizer is so is it better to use this as a spring fertilizer

Also while I'm on with fertilizer’s are all tomato feeds the same or is there a brand that is the best 

I intend to make comfrey also nettle soup with seaweed already in my arsenal I should be ready for next year but buying tomato feed is on my list of things to buy as I don’t think the soup’s will be ready until the end of June next year
