Organic-farming slow-release-fertilizer production method

Abstract

The present invention is adapted to be able to produce an organic-farming fertiliser in the form of granules obtained by separately extracting macroelements or mesoelements from among the 12 essential nutrient elements (N, P, K, Ca, Mg, S, Fe, Mn, Cu, B, Mo and Zn) of edible plants, by means of a predetermined extraction process carried out on oil cake (a common name for the residue which remains after collecting vegetable oils; including soybean cake, pim cake and the like), blood meal (blood of livestock, namely coagulated ox or pig blood), a by-product containing dead fish or fish bone, bone meal, Dead Sea minerals (minerals collected from the Dead Sea; including potassium chloride), chicken egg shells, shellfish shells, oyster shells, natural gypsum, dolomite, phyllite and natural salt, and the invention is adapted to be able to provide fertilisers having elements in ratios suitable for different crops.

Description

technical field [0001] The present invention relates to a manufacturing method of an organic slow-acting fertilizer, and in more detail relates to a manufacturing method of an organic slow-acting fertilizer. The manufacturing method utilizes natural materials to extract 12 essential nutritional elements required for plant growth, namely, N, P, K, Ca, Mg, S, Fe, Mn, Cu, B, Mo, Zn are manufactured as organic fertilizers in accordance with major elements, intermediate elements and mineral fertilizers. Background technique [0002] In general, fertilizers are used to provide nutrients to food plants and ornamental plants to which nutrients are supplied by utilizing water or a nutrient solution obtained by dissolving water. [0003] Fertilizers as mentioned above can be classified into slow-acting fertilizers, chemical fertilizers or organic fertilizers, and chemical fertilizers and slow-acting fertilizers are composed of chemical substances similar to chemical fertilizers, so if...

AI Technical Summary

Problems solved by technology

[0006] However, different plants or animal manure, chicken manure, fishery by-products, and sawdust have different nutritional components and compost production environments depending on the time, state and environment of livestock. When the nutrients required by different edible plants are different, not only can it not produce high-quality edible plants, but also different growers and cultivation areas can produce edible plants of different quality

[0007] Furthermore, it is problematic that when compost contains pathogenic bacteria, it provides a lethal hostile environment for food plants

[0008] In addition, there is a problem that food plants of different quality are produced in different cultivation periods, so it is not possible to provide consumers with safe and high-quality food plants in a balanced manner, and it is impossible to ensure reliability to consumers

[0009] In addition, there are problems in that the existing compost as described above often emits a large amount of bad smell, making the cultivation environment bad, and it is difficult to store and move for a long time, and it is difficult to handle
