What is a fish fertilizer?

There are three main types of fish fertilizers: fish food, hydrolyzed fish and fish emulsion. Outdoor floral or vegetable gardens, fruit trees and even indoor house plants can benefit from this natural fertilizer. For different levels, these fertilizers contain proteins, nitrogen and other micro- and macronutrients that promote healthy, highly producing plants. In addition, they improve soil structure and increase microbial life and also provide a long -term positive impact.

Fish food, the only solid fish fertilizer, is most often made of "garbage" fish such as menhaden, Pollack and the monitor. These fish are heated, pressed and dried and removed fat and oil. In some processes, phosphorus for stabilization and deodorizing food is added. Fish food, most pungent of fish fertilizers, is usually buried in the root zone. Forest with slow release with high nitrogen levels is a fish food especially good for root development and vegetative growth.

hydrolyzed fish are producedfrom whole fresh fish or fish that are distributed by special enzymes. Phosphoric acid is also used in this production process to stop enzymatic digestion. The result is a strong fertilizer similar to a milk cocktail, which is highly soluble in water and can be applied at almost any stage of the growing cycle. No heat is used in the production of hydrolyzed fish, so it maintains more original proteins, hormones and fish vitamins. This makes it top and often more expensive fish fertilizer, which has a strong effect with higher yield for crops and larger, longer -term flowers for flowers.

Fish emulsion, other liquid fish fertilizer, is the third main category. After removing oil, fats and proteins, it is made of porridge that remains from fish. The heating process is removed part of the liquid and creates a syrup emulsion, which is sold as a female Rtilizer. Like other fertilizer fish, phosphoric acid is added to reduce pH levels; Sometimes, howeveríku. Although it has less nutrients than hydrolyzed cold fish, it is also cheaper.

The use of fish as fertilizers has a long history that dates back to ancient Egypt and pre -Columbian companies. In the United States, school children learn about Squanto, an indigenous American who taught this technique to pilgrims in Plymouth Rock. Today, fish fertilizer is attractive to gardeners because it is organic, although some production processes introduce inorganic chemicals. These fertilizers have largely slower speeds of relaxation and are not easy to rule out of the soil, which leads not only in healthier plants, but overall healthier ecosystems.
