NOVELTY - A fertilizer contains (in mass%) base fertilizer (8), additional fertilizer (16), organic substance (25-30), humic acid (15), protein (3-4), biological flora (0.02 billion/g), calcium (3-4), magnesium (2-3), sulfur (2-2.5), boron (0.05-0.08), zinc (0.08-0.1), manganese (0.024-0.05), copper (0.004-0.008), titanium (0.02-0.08), filter residue, mineral elements, marine protein, peanut shell powder, urea, potassium chloride, and functional biological strains from cane sugar industries and wood pulp industries.    USE - The fertilizer is useful for promoting the yield of Barbados nut and oil content of Barbados nut fruit, early fruiting of Barbados nut, increasing stress resistance of Barbados nut, and for improving soil fertility.    ADVANTAGE - The fertilizer protects ecological environment of soil and reduces pollution of inorganic fertilizer in water source, and thus is eco-friendly.    DETAILED DESCRIPTION - A fertilizer comprises (in mass%) nitrogen-phosphorus pentoxide-potassium oxide type base fertilizer (8), nitrogen-phosphorus pentoxide-potassium oxide type additional fertilizer (16), organic substance (25-30), humic acid (15), protein (3-4), biological flora (0.02 billion/g), calcium (3-4), magnesium (2-3), sulfur (2-2.5), boron (0.05-0.08), zinc (0.08-0.1), manganese (0.024-0.05), copper (0.004-0.008), titanium (0.02-0.08), filter residue, mineral elements, marine protein, peanut shell powder, urea, potassium chloride, and functional biological strains from cane sugar industries and wood pulp industries. An INDEPENDENT CLAIM is included for preparation of fertilizer, which involves mixing fish meal, peanut shell powder and microbial strain, stacking and fermenting for 7 days to obtain effective biological flora carrier, add-mixing filter residue, mineral elements, humic acid, peanut shell powder and urea, crushing into 100-120 meshes with a pulverizer, stacking and fermenting for 25 days, measuring and packaging to obtain base fertilizer, and mixing filter residue, humic acid, mineral elements, peanut shell powder, fish meal, urea and potassium chloride, crushing, stacking and fermenting for 25 days to obtain effective biological flora carrier, granulating until the grain size is 1.5-3.5 mm, drying until the water content is 15-18%, cooling to 40-50 degrees C, polishing with a polishing machine and spraying with functional microbial strain during the polishing process, and finally measuring and packaging to obtain additional fertilizer.
