NOVELTY - A plant root-growth-promoting organic fertilizer contains 4-5 pts. wt. potassium chloride, 2-3 pts. wt. urea, 4-5 pts. wt. ethylenediamine-N,N'-bis(2-hydroxyphenylacetic acid) (iron chelate), 25-35 pts. wt. cassava residue, 30-40 pts. wt. rapeseed cake, 6-7 pts. wt. weathered coal, 8-10 pts. wt. molasses, 4-5 pts. wt. sesbania-stem rhizobium nitrogen-fixing root, 8-10 pts. wt. fresh coconut milk, 10-14 pts. wt. fine sand, 6-8 pts. wt. ammonium sulfate, 4-6 pts. wt. gypsum, 3-4 pts. wt. ammonium citrate, 20-30 pts. wt. soil conditioner and remainder of water.    USE - Plant root-growth-promoting organic fertilizer (claimed).    ADVANTAGE - The organic fertilizer efficiently promotes growth of plant root, and provides nutrients to plant root.    DETAILED DESCRIPTION - A plant root-growth-promoting organic fertilizer contains 4-5 pts. wt. potassium chloride, 2-3 pts. wt. urea, 4-5 pts. wt. ethylenediamine-N,N'-bis(2-hydroxyphenylacetic acid) (iron chelate), 25-35 pts. wt. cassava residue, 30-40 pts. wt. rapeseed cake, 6-7 pts. wt. weathered coal, 8-10 pts. wt. molasses, 4-5 pts. wt. sesbania-stem rhizobium nitrogen-fixing root, 8-10 pts. wt. fresh coconut milk, 10-14 pts. wt. fine sand, 6-8 pts. wt. ammonium sulfate, 4-6 pts. wt. gypsum, 3-4 pts. wt. ammonium citrate, 2-3 pts. wt. magnesium sulfate, 20-30 pts. wt. soil conditioner and remainder of water. The soil conditioner contains 8-12 pts. wt. Agaricus blazei mushroom residue, 40-60 pts. wt. beer sludge, 10-15 pts. wt. urea, 20-30 pts. wt. sawdust, 5-6 pts. wt. ethylenediamine-N,N'-bis(2-hydroxyphenylacetic acid) (iron chelate), 5-6 pts. wt. copper amino acid chelate, 5-6 pts. wt. magnesium amino acid chelate, 5-6 pts. wt. calcium amino acid chelate, 5-6 pts. wt. boron amino acid chelate, 5-6 pts. wt. manganese amino acid chelate, 5-6 pts. wt. zinc amino acid chelate, 2-3 pts. wt. polyacrylamide, 1-2 pts. wt. potassium feldspar powder and 4-5 pts. wt. EM-type agent. The soil conditioner is prepared by mixing ethylenediamine-N,N'-bis(2-hydroxyphenylacetic acid) (iron chelate), copper amino acid chelate, magnesium amino acid chelate, calcium amino acid chelate, boron amino acid chelate, manganese amino acid chelate and zinc amino acid chelate to form fine powder, adding and mixing beer sludge and sawdust, adding EM-type agent and Agaricus blazei mushroom residue, adjusting water content of compost to 60-70%, piling aerobic hot compost for 6-8 days, turning inside and outside for 4-5 times, fermenting at 50-60 degrees C for 25-35 days, drying and pulverizing fermented beer sludge compost, mixing compost dry powder, spray-granulating urea with mixed powder to form spherical particles, spraying polyacrylamide and potassium feldspar powder on outer surface of particles, cooling and drying coated particles at low temperature. An INDEPENDENT CLAIM is included for preparation of plant root-growth-promoting organic fertilizer.
