Abstract

The present invention relates to a method for preparing a liquid composition for preventing soil erosion and enhancing the functionality of herbicides, and the liquid composition itself. The present invention comprises: a first step of adding 3-7% by weight of starch and 93-97% by weight of water to a container and mixing at 30-50°C for 25-35 minutes; a second step of adding sugars to the mixture mixed in the first step, wherein 3-10% by weight of sugars is added relative to the total weight of the mixture and mixing at 40-55°C for 25-35 minutes; a third step of adding a plasticizer to the mixture mixed in the second step, wherein 2-5% by weight of the plasticizer is added relative to the total weight of the mixture and mixing at 50-70°C for 25-35 minutes; and a fourth step of adding a crosslinking agent to the mixture mixed in the third step, wherein 2-5% by weight of the crosslinking agent is added relative to the total weight of the mixture and mixing at 70-95°C for 25-35 minutes. According to the present invention, the loss of herbicides sprayed on the soil to remove weeds can be minimized so that the effect of the herbicide can be continuously maintained until the crop is harvested.

Description

Method for producing a liquid composition for preventing soil loss and increasing herbicide function and the liquid composition thereof The present invention relates to a method for preparing a liquid composition for preventing soil erosion and enhancing herbicide functionality, and to the liquid composition. Herbicides are applied to the soil where crops are planted to eliminate weeds that affect crop yields. However, because the herbicides applied to the soil are easily washed away, they fail to act sufficiently to eliminate weeds, leading to frequent application. Consequently, the excessive use of herbicides results in leakage or leaching, causing phytotoxicity to non-target crops and leading to water source pollution and environmental damage. Removing weeds manually without using herbicides increases labor costs. As an alternative to address these problems, plastic mulch is used to coat the soil. Applying mulch to the soil not only suppresses weed growth but also provides benefits such as soil insulation, moisture retention, and pest and disease prevention. This not only increases crop yields but also reduces labor input, thereby boosting income. However, the use of mulch requires labor because the film must be removed from the soil after the crops are harvested. If the mulch is not completely removed, residual fragments can worsen root growth and soil drainage when crops are grown in the following year. Furthermore, since mulch is difficult to decompose under natural conditions and cannot be recycled, it causes environmental pollution in rural areas. FIG. 1 is a flowchart illustrating an embodiment of a method for preparing a liquid composition for preventing soil erosion and enhancing herbicide functionality according to the present invention. FIG. 2 is a photographic drawing illustrating the state of spraying a liquid composition for preventing soil erosion and enhancing herbicide functionality according to the present invention onto soil. FIG. 3 is a photographic drawing of a field sprayed with a liquid composition for preventing soil erosion and enhancing herbicide functionality according to the present invention, and the state of crop growth. Hereinafter, a method for preparing a liquid composition for preventing soil erosion and enhancing herbicide functionality according to the present invention and an example of the liquid composition will be described with reference to the attached drawings. As illustrated in FIG. 1, first, in an embodiment of the method for preparing a liquid composition for preventing soil erosion and enhancing herbicide functionality according to the present invention , a first step (S10) is carried out in which 3 to 7 weight% of starch and 93 to 97 weight% of water are added to a container and mixed at 30 to 50°C for 25 to 35 minutes. It is preferable that the starch be one of wheat starch, corn starch, rice starch, potato starch, sweet potato starch, or kudzu starch. Meanwhile, the starch may be two or more of wheat starch, corn starch, rice starch, potato starch, sweet potato starch, and kudzu starch. In step 1 (S10), the starch mixed with water is heated, and as the surface of some starch particles softens and expands, the viscosity increases slightly, resulting in partial gelatinization. After performing Step 1 (S10), Step 2 (S20) is performed by adding sugars to the mixture mixed in Step 1 (S10), adding 3 to 10 weight percent of sugars relative to the total weight of the mixture, and mixing at 40 to 55°C for 25 to 35 minutes. It is preferable that the sugar be any one of glucose, fructose, sucrose, lactose, maltose, starch, glycogen, or cellulose. Meanwhile, sugars may be two or more of glucose, fructose, sucrose, lactose, maltose, starch, glycogen, and cellulose. In step 2 (S20), sugars are added at a temperature 5 to 10°C higher than the temperature of the mixture in step 1 (S10), making temperature control easy and fast. In step 2 (S30), the starch particles may swell slightly and a slight increase in viscosity may occur, but the mixing of sugars inhibits the gelatinization of the starch, and the sugars surround the starch particles to form a protective film, thereby reducing contact with water, reducing viscosity, and increasing saturation. After performing step 2 (S20), step 3 (S30) is performed in which a plasticizer is added to the mixture mixed in step 2, with 2 to 5 weight percent of the plasticizer added relative to the total weight of the mixture, and the mixture is mixed at 50 to 70°C for 25 to 35 minutes. It is preferable that the plasticizer be one of citric acid, oxalic acid, or succinic acid. The plasticizer may be any two or more of citric acid, oxalic acid, and succinic acid. In step 3 (S30), the plasticizer is added at a temperature 10 to 15°C higher than the temperature of the mixture in step 2 (S20), making temperature control easy and fast. In step 3 (S30), the mixture becomes a flexible opaque suspension containing some ungelatinized starch part
