Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a novel paste-like fertilizer composition containing an alcoholic fermentation residue.

More specifically, a paste is obtained by evaporating and concentrating the fermentation residue to a solid content of about 45% and adding and mixing fertilizer raw materials whose main components are nitrogen, phosphoric acid, and potassium, which are the three elements of fertilizer. This is related to fertilizers.

Generally, the fermentation residue contains various nutrients such as crude protein, vitamins, soluble nitrogen-free substances, amino acids, and various other trace elements, and is used as feed or fertilizer raw material.

The present inventors have been conducting research on using alcohol distillation residue concentrate as a liquid fertilizer, and as a result of further research, they were able to obtain a paste-like fertilizer that has both solid and liquid properties.

The present invention uses urea, ammonium sulfate, ammonia, phosphoric acid, and ammonia phosphate in an alcohol distillation residue concentrate made from molasses.

A paste-like fertilizer is obtained by appropriately adding and mixing ammonia acetate, potassium chloride, potassium phosphate, etc., and adjusting the contents of nitrogen, phosphoric acid, and potassium as fertilizer components.

The conditions for making this paste are as follows: alcoholic fermentation distillation residue concentrated to a solid content of 40 to 45 parts or more, nitrogen (N) of 1 to 7 parts, and phosphoric acid (P2O3) of 4 to 4 parts.
Section 13: Add potassium (K2O) to 2-7%.

The paste fertilizer thus obtained has physical properties of hardness of 0.28 kg or more and gum properties of 0.19 or more when measured using a texturometer (manufactured by General Foods).

In addition, these physical properties show almost no change even after being stored under harsh conditions of 30°C or higher for more than a month.
During this period, no mold or other growth was observed, and it has excellent properties as a paste fertilizer.

The paste fertilizer using the alcohol fermentation distillation residue concentrate according to the present invention not only corrects the imbalance of the three elements when the concentrate is used alone as a fertilizer, but also eliminates the inconvenience in fertilizing due to the formation of precipitates. This problem has been resolved, and the flow of components through watering, as in the case of liquid fertilizers, has also been improved.

Furthermore, the results of a fertilizer efficacy test using late maturing Japanese mustard spinach showed superior fresh weights of 178 to 184 compared to the control group 100.
