Cell free supernatant composition of microbial culture for agricultural use

A cell-free supernatant composition comprising:

• (i) an isolated cell-free supernatant of a microbial culture, obtained by (1) inoculating an isolated mixed microbial composition comprising isolated microorganisms of IN-M1, ATCC Patent Deposit Designation No. PTA-12383 into a culture medium comprising water, a molasses, a mineral powder, a sea salt, and a wheat bran, (2) incubating the inoculated media for 3-10 weeks at 30-32 or 35-37 or 32-37 degrees Celsius, thereby obtaining the microbial culture, and (3) centrifuging the microbial culture to separate microbial culture cells from a supernatant and filter sterilizing the supernatant to obtain the cell-free supernatant of the microbial culture, wherein the cell free supernatant comprises at least 2500 micrograms potassium per gram of cell-free supernatant, at least 435 micrograms nitrogen per gram of cell-free supernatant, at least 475 micrograms calcium per gram of cell-free supernatant, and at least 200 micrograms magnesium per gram of cell-free supernatant, and
• (ii) diluent water,
• wherein the ratio between the cell-free supernatant of the microbial culture and the diluent water in the cell-free supernatant composition is between 1:25 and 1:1000.
