Method of using thermally hydrolized feather keratin hydrolysate peptides (khp) in protecting plants against acidity stress

A method of using a keratin hydrolysis peptide (KHP) solution to promote the growth of farming plants under acidity stress, comprising 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;
• and
• d. Apply to water or soil wherein intended farming plants are grown.
