BACKGROUND OF THE INVENTION

Present invention disclosed and claimed the method and application of a keratin hydrolysis peptide (“KHP”) solution to promote the growth of corn plants under low light conditions.


The application of the KHP solution is by infusing the solution in the soil when corns are sown and until reaching the vegetative growth period; alternatively, by spraying the solution on the leaves of corns during the vegetative growth period.


Many factors will affect the growth and production of farming crops. The two dominant factors are insufficient light exposure and over-usage of nitrogen fertilizers.


Over-usage of nitrogen fertilizers similarly cause many plants to grow higher, though the internal metabolism of plants would become imbalanced, and will lead to weaker general health and lower ultimate production yield of farming crops.


When the light exposure is insufficient, the plants' photosynthesis activities are negatively affected, the internal hormones of plants would adjust and react to cause the plants to grow higher for better light exposure, this tends to generate slender stalk width. The insufficient light exposure problem also happens when plants are grown too densely together, resulting in reduced light exposure to leaves that are situated at lower height, and a Shade Avoidance Syndrome (SAS), that produced weaker stem/stalk and ultimately low production of farming crops.


Hydrolyzed keratin has long been used to strengthen hairs, reduce hair splitting and breakage. Other beneficial uses include skin moisturization and wound healing. Keratin hydrolysate has also been known to function as a biofertilizer, boosting plants' growth by enhancing the plants' ability to receive and utilize nutrients, including commonly applied fertilizers.


The KHP solution is made by a hydrolysis process using feathers and water, via a high-temperature and high-pressure process, resulting in a solution that has many beneficial applications in the fields of horticulture, agriculture and potentially other farming businesses.


Among the embodiments disclosed and claimed in this application, one specific embodiment used feathers only, without water, to be treated with the high-temperature and high-pressure process as taught herein to produce a specific version of the KHP solution.


The inventors, using the KHP solutions made as disclosed herein, and applied to the corn plants, at the seeding stage and during the vegetative stage, and proved that the adverse impact of the low light exposure can be effective remedied as more detailed below.


As disclosed herein, the application of the KHP solutions can be done by infusing to the soil when the seeds are planted, or by spraying to the leaf surface during the vegetative period, which is the time between the growth of third leaf circle to the growth of the fourth leaf circle. Either method of application can boost the development of above-ground bio mass and the under-ground root system of the corn plants, despite the corn plants may suffer from degraded photosynthesis and metabolism activities due to low light exposure.


SUMMARY OF THE INVENTION

The keratin solution is primarily based upon feather, which contains 85-91% keratin, 13-15% organic nitrogen, 1.6-2% organic sulfur, as well as other materials. The high keratin content has drawn many prior researches that work to break down, by enzyme, chemical agents, or fermentation process, into peptides, amino acids and other smaller molecules that can be used for animal feeds, plant fertilizers, and cultivation bases.


Around 2019, Nurdiawati, et al, came up with a hydrolysis process, by the mixture of a-amylase and protease to hydrolyze feather waste, resulting in a mixture of amino acids, fatty acids, and sugars. Nurdiawati experimented and adopted certain specific high-temperature and high-pressure setting in the hydrolysis process and discovered that the resulting solution, when mixed with some potassium and other minerals, can boost the growth of Pogostemon cablin and Vigna radiata, as reported in International Journal of Recycling or Organic Waste in Agriculture (8:221-232, 2019).


The inventors of present application, under the aegis of CH Biotech, developed and selected different feather and water compositions to perform the hydrolysis at higher temperature and higher pressure setting, resulting with different keratin hydrolysis peptide (“KHP”) solution that can be used on different crops/plants.


The selected embodiment of present invention uses a mixture of water and feathers, and subject the mixture to a thermal hydrolysis process to create KHP solutions based upon temperature/pressure parameters as noted below.


The inventors used Dionex UltiMate 3000 UPLC to separate the peptides; an analysis is done via Thermo Orbitrap Fushion Lumos Tribrid Orbitrap mass spectrometry to identify the peptides, which are then subsequently confirmed by looking up the BIOPEP-UWM database.


A preferred dilution ratio is 50-500 times (noted as 50×-500×) of water by volume.

A first embodiment of keratin hydrolysis peptide (KHP) solution, without water, can be made by 70 kg of feathers, with the feathers' water content being 46%, and then treated by the steps of:

    • a. stirring the feathers in a sealed container;
    • b. hydrolyzing the feathers in the container with a temperature and pressure setting of 180° C. and 13 kg/cm2 for a duration of 40 minutes;
    • c. using a mass spectrometer to confirm the combination of peptides in the solution to contain at least 253 peptides as listed in the specification whereby their molecular masses are between 705.9 and 3,194.7 Dalton, and the concentration is in the range of 2.0×105˜4.5×105 ppm.


The keratin hydrolysis peptide (KHP) solution of the first embodiment is further filtered and concentrated to 381,250 ppm concentration.


The hydrolysis process in the second embodiment takes the steps of:

    • a. Preparing the KHP solution by mixing 66 kg of feathers whose content is 50% water and 44 kg of water in a sealed container,
    • b. hydrolyzing the mixture in the container with a temperature and pressure setting of 195° C. and 16 kg/cm2 for a duration of 40 minutes;
    • c. using a mass spectrometer to confirm the combination of peptides in the solution to contain at least 253 peptides as listed in the specification where their molecular masses are between 500 and 4,000 Daltons, and the concentration is in the range of 2.0×105˜4.5×105 ppm.


The keratin hydrolysis peptide (KHP) solution of the second embodiment is further filtered and concentrated to 200,000 ppm concentration.


The confirmation of some of the 253 peptides is further done by referencing the BIOPEP-UWM database.


The KHP solution in the first embodiment will be denoted as KHP-1; the KHP solution in the second embodiment will be denoted as KHP-2. The solutions of both embodiments can be diluted with water at the ratio of between 50 times to 500 times, denoted as 50×-500×, before applied to the corn, either by infusing to the soil or by spraying to the leaf surface.


The method of applying the KHP solutions to corn plants, to remedy the adverse impact of low light exposure, depends on the timing of the application. Among the growth stages after germination of corn plants, the vegetative stage include VE (sheath leaf protruding from ground), V1 (first leaf circle visible), V2 (second leaf circle visible), V3 (third leaf circle visible), V4 (fourth leaf circle visible, stem top branching tissue underground), V5 (fifth leaf circle visible, stem top branching tissue above ground), etc.


The inventors tested the KHP solutions in two application methods to combat the adverse impact of low light exposure: soil infusion and leaf spray.


For the soil infusion, the KHP solutions were applied to the soil when corn seeds are planted into the soil. From seeding to the VE stage (about 6 days), using a shade to block out the light, creating the low light adverse condition.


The table below shows different groups of corn planting, up to the VE stage, and the growing conditions:

The Normal Light Group is given full light (noted as FL), having illumination of 27,000 lux. Two groups (1 and 2) are given reduced light exposure. In each of the 2 groups, A and B sub-groups received KHP solutions with 100× and 50× dilution ratios respective.


The two reduced light groups (1 and 2) have light illumination of 19,000 lux (Medium Light, denoted as ML) and 12,000 lux (Low Light, denoted as LL).


Based upon the group settings defined herein, the inventors took various measurements to determine the underground bio mass dry weights and the boost from the method of KHP application to the medium and low light corn groups.


As shown in FIG. 1, the two reduced light groups 1 and 2 show worse underground bio mass dry weights than the Normal Light group; this especially so in the Low Light group.


With infusion of the KHP solutions after seeding, it can be seen that, under the Medium Light condition (group 2), the Experiment 1B sub-group, with KHP-1 50× solution, has the biggest boost to the root development, up to 39% over that of the Check group 1. The Experiment 1A sub-group, with KHP-1100× solution, shows 16% increase. Notably, the 2 sub-groups in the Medium Light group show better root system development than that of the Normal Light group.


In the Low Light group (group 2), the KHP-1 50× and KHP-1 100× applications shows improved root system development better than the Check 2 group, though they did not exceed that of the natural Normal Light group.


The method of infusion of KHP-1 50× and KHP-1 100× at seeding stage also show improvement to the stalk height and width, as shown in FIGS. 2A and 2B.



FIG. 2A shows that, in the Medium Light group, not only are the stalk heights exceed the Check 1 group, they are also better than the Normal Light group. In the Low Light group, the KHP solutions effectively boost up the height of the corn plants than that of the Check 2 group, with that of the Experiment 2A group (KHP-1 100×) also exceeds that of the Normal Light group.



FIG. 2B shows that, in the Medium Light group, the Experiment 1A and Experiment 1B both have stalk width exceed the Check 1 group and the Normal Light group. In the Low Light group, the two sub-groups with the KHP-1 solutions show better stalk heights than that of the Check group 2. Also, in terms of the stalk width, the higher KHP solution's concentration has clearly better result.


The remedial effect of the method of the KHP solutions to the leaf surface area, when infused to the soil containing the corn seeds, is shown in FIG. 3. It can be seen that in the Medium Light group, the Experiment 1A and Experiment 1B both have larger total leaf area than that of the Normal Light group. It is also obvious that higher KHP concentration (in 1B and 2B, using the 50× dilution ratio) works better.


When measuring the above-ground bio mass dry weights and fresh weights, the remedial effect of the method of KHP solution to overcome the negative impact of lower light exposure. As shown in FIG. 4A, especially in the Medium Light group, both the Experiment 1A and Experiment 1B sub-groups show substantial improvement of fresh weights over the Check group 1, and even better than the Normal Light group. Also, in both Medium Light and Low Light groups, the higher KHP solution's concentration also has better remedial effect.



FIG. 4B show the measurements of above-ground bio mass dry weights. The results are similar to those in FIG. 4A where the remedial effects in the Medium Light group are substantial, with the weights exceeding that of the Normal Light group; the higher KHP solution's concentration shows better result.


The inventors further tested the leaf spray application of the KHP-1 and KHP-2 solutions in a Group 3 setting as shown below. The Check 3 group is given water only whereas the Experiment 3A and Experiment 3B groups are given KHP-1 500× solution and KHP-2 500× solution respectively by leaf-spraying.

During the vegetative period of V3-V4, the light exposure is reduced to 14,000 lux, from the prior normal light illumination of 27,000 lux. The sub-groups of Experiment 3A and Experiment 3B are given leaf-spray of the KHP-1 and KHP-2 solutions, respectively, at the same 500× dilution ratio.



FIG. 5A shows the remedial effect of the method of leaf-spray application of KHP solutions to the plant heights. FIG. 5B shows the remedial effect of the KHP solutions to the stalk width. As clearly shown, in a reduced light exposure setting, the leaf-spray application of the KHP solutions improved both plant's heights and stalk widths.



FIG. 6 shows the result of leaf spray of KHP solutions, during the corn's vegetative period, to the leaf's surface area. As shown, both Experiment 3A and Experiment 3B groups have substantially larger leaf surface area than that of the Check 3 group.



FIG. 7 shows the result of leaf spray of KHP solutions improved the above-ground bio mass dry weights over that of the Check 3 group under low light condition. Especially the Experiment 3A group shows 48% increase over that of the Check 3 group.


Based upon the tests and experiments done by the inventors, it is confirmed that application of the KHP solutions, at the dilution ratios and the growth stages as disclosed herein, worked to reduce the adverse impact of low light exposure to the corn's growth; in some instances, the corns aided by the KHP solutions perform better than the corn grown with normal light settings.


It can be seen that the method of applying KHP solutions as disclosed herein effectively remedied the injuries and stunted growth of corn under low light exposure, improved the capacities of metabolism and photosynthesis and, ultimately increased the production yield of corn.
