NpK lawn feed?

[Chrispowell]

Afternoon all,

Does anyone make a lawn feed from their dry salts?

I would love to make my own and assume all the salts for aquariums would also benefit the lawn?

Thanks

Chris

Hello,
one can though the dry salts used for aquariums are often of better purity and more expensive. Lawn fertilizer also has more ammonia in it. In quantity, it likely will be cheaper to buy lawn fertilizer than make your own mix. Using aquarium water on the lawn helps repurpose some of the fertilizers though

Generally non aquatic fertilizers user ammonia based salts, doubt will be ammonium nitrate (as this is strictly controlled) but things like urea, calcium ammonium nitrate, ammonium citrate and other ammonium compounds. These ammonium based compounds are toxic to aquatic life, which is why they are not used for aquatic plant fertilizers.
