NOVELTY - Corn straw organic fertilizer comprises 50-70 pts. wt. corn straw, 5-8 pts. wt. ammonium bicarbonate, 12-16 pts. wt. urea, 15-20 pts. wt. potassium sulfate, 10-15 pts. wt. calcium magnesium phosphate fertilizer, 20-30 pts. wt. dry cow manure, 5-10 pts. wt. hawthorn sludge, 2-3 pts. wt. effective microorganism (EM) agent, 3-5 pts. wt. additives and water.    USE - Corn straw organic fertilizer.    ADVANTAGE - The fertilizer improves hydrophilic surface, increases surface area contact with water and soil colloid degree and produces sticky surface.    DETAILED DESCRIPTION - Corn straw organic fertilizer comprises 50-70 pts. wt. corn straw, 5-8 pts. wt. ammonium bicarbonate, 12-16 pts. wt. urea, 15-20 pts. wt. potassium sulfate, 10-15 pts. wt. calcium magnesium phosphate fertilizer, 20-30 pts. wt. dry cow manure, 5-10 pts. wt. hawthorn sludge, 2-3 pts. wt. effective microorganism (EM) agent, 3-5 pts. wt. additives and water. The additive comprises 1-2 pts. wt. sodium dodecyl sulfate, 6-8 pts. wt. medical stone powder, 7-10 pts. wt. vinyl acetate, 6-9 pts. wt. ethanol, 2-3 pts. wt. N,N-methylene-bis-acrylamide and 30 pts. wt. water. The preparation of additive is done by mixing ethanol and water in reactor, adding vinyl acetate and N,N-methylene-bis-acrylamide, stirring with 150-200 revolutions/minute (rpm) speed for 5-10 minutes, adding sodium lauryl sulfate and medical stone powder and stirring with 250-400 rpm speed for 0.5-1 hour. An INDEPENDENT CLAIM is included for preparation of corn straw organic fertilizer comprises crushing crop straw to 3-4 cm fragment, adding 2-3 times water and ammonium hydrogen phosphate, stirring to dissolve, ammoniating at 30-35 degrees C for 15-18 days and filtering to remove excess water residue; placing in microwave processing machine and treating with 230-250 w microwave power for 5-10 minutes; mixing with EM agent, dry cow manure and hawthorn sludge, adjusting water content to 60%, mixing and fermenting for 6-10 days; and crushing fermented material, adding additive, mixing, adding urea, potassium sulfate, calcium magnesium phosphate fertilizer and other remaining components, adjusting moisture content to 20% and granulating.
