Abstract: The research tackles a new study of preparing liquid organic fertilizers to be used in the agricultural sector which are more active than the traditional solid organic ones. These fertilizers are extracted from fish waste the manufacturing of such fertilizers is characterized by low cost easy preparation and the availability of the raw material in our country Iraq. The wastes which are namely (guts and other wastes) are grinded mechanically then by using the phosphoric acid they are chemically dissolved. That is done under certain and controlled conditions concerning the temperature the hydrogen index (pH) and the existence of air (oxygen). After preparing several samples under various conditions the nitrogen, phosphorus and potassium rates were measured by using the (NPK) measures of some of the already prepared samples. It was proved that they contain considerable amounts of these three elements which are necessary for growing and soil and they could be used on a large scale in the agriculture sector. The research included a new study for the preparation of liquid organic fertilizers for use in the agricultural sector more effective than conventional solid organic fertilizers. These fertilizers are extracted from fish waste. These residues are subject to a mechanical digestion process followed by chemical digestion using phosphoric acid with certain conditions such as temperature, pH (acid function) and air (oxygen) being observed. After the preparation of several models and different conditions the ratio of nitrogen, phosphorus and potassium was measured using the NPK, manganese, iron and sulfur measurements as well as the lead element of some prepared models. It has been proven to contain adequate quantities of these three important elements of germination and soil as well as other minor elements agriculture sector.
