NOVELTY - Soil-compaction preventing organic fertilizer comprises 40-50 pts. furfural residue, 33-50 pts. urea, 12-16 pts. soapstock, 8-12 pts. soy sauce residue, 8-10 pts. actinolite stone powder, 6-8 pts. attapulgite, 6-7 pts. potassium sulfate, 5-6 pts. potassium hydroxide, 5-6 pts. ammonium sulfate, 4-6 pts. ammonium bicarbonate, 3-5 pts. barium chloride, 3-5 pts. strontium chloride, 3-5 pts. calcium chloride, 4-5 pts. magnesium sulfate, 4-5 pts. effective-microorganism inoculum and proper amount of water and soil modifier e.g. albic soil, kanuma soil, birch sawdust, maple leaves, fresh shrub.    USE - The organic fertilizer is useful in preventing soil-compaction (claimed).    ADVANTAGE - The fertilizer improves crop-quality and crop-yield, fixes nitrogen into soil and conducive to plant growth.    DETAILED DESCRIPTION - Soil-compaction preventing organic fertilizer comprises 40-50 pts. furfural residue, 33-50 pts. urea, 12-16 pts. soapstock, 8-12 pts. soy sauce residue, 8-10 pts. actinolite stone powder, 6-8 pts. attapulgite, 6-7 pts. potassium sulfate, 5-6 pts. potassium hydroxide, 5-6 pts. ammonium sulfate, 4-6 pts. ammonium bicarbonate, 3-5 pts. barium chloride, 3-5 pts. strontium chloride, 3-5 pts. calcium chloride, 4-5 pts. magnesium sulfate, 4-5 pts. effective-microorganism inoculum and proper amount of water and soil modifier including 18-24 pts. albic soil, 14-18 pts. kanuma soil, 10-15 pts. birch sawdust, 9-16 pts. maple leaves, 8-12 pts. fresh shrub, 6-8 pts. Crotalaria assamica, 6-7 pts. fulvic acid, 5-8 pts. nano-carbon powder, 4-7 pts. white turnip skin, 5-6 pts. zinc gluconate, 4-6 pts. water hyacinth, 4-6 pts. radix ampelopsis, 3-5 pts. dicalcium phosphate and 4-5 pts. calcium cyanamide. The soil modifier is prepared by calcining the albic soil and kanuma soil, mixing for 40-60 minutes and grinding into fine powder, wrapping the water hyacinth, radix ampelopsis and Crotalaria assamica in a white cloth and pressing to obtain slurry, then mixing the slurry with resultant fine powder and dicalcium phosphate, calcium cyanamide and zinc gluconate by stirring uniformly into a paste, mixing the pressed residue with crushed fresh shrub, fulvic acid, white turnip ski, birch sawdust and maple leaves in a water pit, allowing to compost for 15-20 days by adding nanocarbon powder once for every 2-4 days and stirring uniformly to obtain compost product, then mixing the compost powder with paste, drying and granulating. An INDEPENDENT CLAIM is also included for preparing organic fertilizer, comprising: (i) grinding ammonium sulfate, potassium sulfate, ammonium bicarbonate, potassium hydroxide, magnesium sulfate with proper amount of water into slurry, then subjecting to spray-drying to obtain a powder; (ii) blending the barium chloride, strontium chloride, calcium chloride, attapulgite and urea with proper amount of water by stirring to obtain a paste, then drying and granulating; (iii) drying and mixing the furfural residue, actinolite stone powder, soapstock and soy sauce residue, then adding effective-microorganism inoculum, drop-wisely adding small amount of water and fermenting at room temperature under aerobic condition for 20-30 days, then drying, extruding and granulating the fermented material; and (iv) adding remaining materials into the fermented material and mixing uniformly.
