Has anyone here actually tried fish oil fertilizers on hay fields or pasture?

Question

Ghost who walk

actually fish meal has zero nitrogen. It has a high phosphorus content and high calcium and other micronutrient content, but of the major three it only has phosphorus.

Answer 1

Fish oil is a reppeleant against insect pests and not fertilizer. But fish meal ( waste fish) is a manure which has high C:N ratio and has to be mixed with soil to help digest the fish and lower :N ratio so that plants get the nutrients. You can mix fish meal with soil and water in 1:1:10 ratio(fish:soil:water) and add yeast to it and keep for 1 week. Shake well daily for fermentation. Then the solution may be filtered and add 20 times water to dilute and spray on pasture.

Answer 2

the first settlers used fish for fertilizer. Sounds like a screwball idea today.

Answer 3

Fish oil is an excellent fertilizer, but I doubt that it would be cost effective on pasture or hay fields.
