NOVELTY - Liquid fertilizer comprises 33-37 pts. wt. soybean powder, 12-16 pts. wt. wood vinegar, 48-52 pts. wt. mushroom residue, 18-20 pts. wt. potassium sulfate, 50-55 pts. wt. fresh pig intestine, 12-15 pts. wt. fulvic acid, 120-140 pts. wt. waste poultry feathers, 6-9 pts. wt. copper sulfate, 3-5 pts. wt. ferrous sulfate, 4-6 pts. wt. genetically modified (GM) microbial agent, and suitable amount of water.    USE - The liquid fertilizer is useful for enhancing disease resistance property of crops (claimed).    ADVANTAGE - The liquid fertilizer improves yield and quality of crops, supplements nutritional components to crops, inhibits growth of pathogen in crops, and reduces physiological diseases of crops.    DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for method for preparing the liquid fertilizer, which involves (a) washing and drying the waste poultry feathers, crushing the waste poultry feathers, dividing crushed waste poultry feathers into two portions, adding 10 times sulfuric acid solution (having concentration of 3 mol/l) to one portion of the crushed waste poultry feathers, performing hydrolysis using microwave oven for 220-240 minutes, adding 10 times potassium hydroxide solution (having concentration of 6 mol/l) to another portion of the crushed waste poultry feathers, and performing hydrolysis using microwave oven for 260-280 minutes, (b) mixing hydrolyzates obtained in step (a), uniformly stirring obtained mixture, filtering the mixture to obtain supernatant and organic residues, adding wood vinegar and copper sulfate to the supernatant, regulating pH of obtained mixture to 6, heating the mixture at 60-65 degrees C for 80-90 minutes, adding ferrous sulfate to the mixture, heating the mixture at 70-80 degrees C for 40-60 minutes to obtain solution comprising amino acid chelates, (c) mixing the organic residues obtained in step (b) with the mushroom residue, soybean powder and fresh pig intestine, adding obtained mixture to fermentation tank, adding suitable amount of water to the mixture such that water content of the mixture is controlled at 45-55%, and fermenting the mixture for 35-40 days, (d) adding 8-10 times water and GM microbial agent to fermented product obtained in step (c), uniformly stirring obtained mixture, adding the mixture to a breathable container, maintaining the mixture for 35-45 hours, continuously stirring the mixture the mixture, and filtering the mixture using double-layer yarn cloth to obtain filtrate, and (e) mixing the solution comprising amino acid chelates with the filtrate obtained in step (d), potassium sulfate, fulvic acid and remaining components, uniformly stirring obtained mixture, and adding the mixture to magnetizer for processing the mixture at 350-450 mT 10-15 minutes to obtain product.
