NOVELTY - Liquid fertilizer comprises 14-16 pts. wt. maple syrup, 36-40 pts. wt. lobster shell, 3-4 pts. wt. sodium selenite, 40-50 pts. wt. eggshell powder, 34-38 pts. wt. sawdust, 13-16 pts. wt. potassium hydrogen phosphate, 140-150 pts. wt. poultry feather waste, 3-4 pts. wt. copper sulfate, 5-7 pts. wt. ferrous sulfate, 3-5 pts. wt. genetically modified (GM) microbial agent, and suitable amount of water.    USE - The liquid fertilizer is useful for promoting absorption of soil trace elements by crops (claimed).    ADVANTAGE - The fertilizer improves growth environment of crops, and absorption of nutritional components including iron and zinc by crops.    DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for method for preparing the liquid fertilizer, which involves (a) washing and drying poultry feather waste, crushing dried poultry feather waste, dividing obtained powder into two portions, adding 10 times sulfuric acid solution (having concentration of 3 mol/l) to one portion of the powder, subjecting obtained mixture to hydrolysis for 220-260 minutes using microwave oven, adding 10 times potassium hydroxide solution (having concentration of 6 mol/l), and subjecting obtained mixture to hydrolysis for 260-280 minutes using microwave oven, (b) mixing hydrolyzates obtained in step (a), uniformly stirring obtained mixture, filtering the mixture to obtain supernatant and organic residues, adding the maple syrup and copper sulfate to the supernatant, controlling pH of obtained mixture at 6, heating the mixture at 55-60 degrees C for 70-80 minutes, adding ferrous sulfate to the mixture, and reacting obtained mixture at 75-80 degrees C for 50-60 minutes to obtain amino acid chelates-containing solution, (c) mixing the organic residue obtained n step (b) with the eggshell powder, sawdust and lobster shell, adding obtained mixture to fermentation tank, adding suitable amount of water to the mixture, controlling water content of the mixture at 45-55%, and fermenting the mixture for 30-50 days, (d) adding 8-10 times water and GM microbial agent to fermented product obtained in step (c), then adding obtained mixture to breathable container, uniformly stirring the mixture for 28-32 hours, and filtering the mixture using double-layer gauze filter, and (e) mixing the amino acid chelates-containing solution obtained in step (b), product obtained in step (d), sodium selenite and potassium hydrogen phosphate, uniformly stirring obtained mixture, and subjecting the mixture to magnetization at 450-550 mT for 8-10 minutes to obtain product.
