Specialized fertilizers
Nowadays, due to the emergence of environmental problems, organic agriculture has received much attention. In many agricultural systems, more than composts and organic materials (organic materials are among the main factors of soil fertility) they are used as fertilizers, which improve soil conditions and fertility, as well as prevent and control some plant diseases and pests. One of the organic sources is fish manure, which is effective on plant germination and growth.
Fish fertilizers
Fish fertilizers can be made by fish meal and waste of caught fish. Because of their high carbon content and amino acids, these fertilizers are widely used for greenhouse plants, orchard trees, farms, and even soil amelioration.
