3 Fish Emulsion Nutrient Release Rate Facts 3 Fish Emulsion Nutrient Release Rate Facts
Fish emulsion is useful in feeding perennials and vegetables. It's often used in greenhouse plants, and is sometimes found in some pest control methods. If you are considering using fish emulsion, here are some facts about the release rate that you should know.
1 –The burn potential is greatly minimized, if used correctly.
While some sources list the nutrient burn potential of fish emulsion as medium high, the research has shown that if diluted properly, according to directions listed on your bottle or recipe, there should be no nutrient burn whatsoever. This makes the fish emulsion not only a healthy choice for your garden, plant, or yard, but also an effective composting supplement to add to your soil. The lack of burn is evidence of a slow nutrient release, which can be beneficial for plants that need continual nourishment.
2 – Nitrogen contained in fish emulsion releases slower than other fertilizers.
A great perk to using fish emulsion is the amount of nitrogen that is contained in it naturally. The release of the nitrogen is also slow. By comparison to a generic nitrogen fertilizer, fish emulsions contain other nutrients to help support the nitrogen and slow down its release into the soil.
3 – The nutrients tend to stay in the soil and on the leaves.
The most common uses of a fish emulsion are to either compost it, create a “tea” by diluting it with water, or through direct foliar feeding at a weaker concentration. However, with proper application every month or as needed, nutrients will stay in the soil and be drawn into the plant longer. You don’t want to fertilize too much, which would cause too much of any given nutrient to poison the plant. If used correctly, the soil’s nourishing qualities won’t diminish over time or from rain runoff as would occur with irregular fertilization or under fertilization.
