Jeevamrutha is a natural liquid fertilizer. It is made by mixing water, dung (in the form of manure) and urine from cows with some mud from the same area as the manure will be applied in later. Food is then added to speed the growth of microbes: jaggery or flour can be used. Jeevamrutha has been used by Indian farmers for centuries, falling out of use for some time before being revived in the 2000s. Urine-based biopesticides Urine-based biopesticides are a crude form of alcohol-based disinfectants widely used in killing some viruses/bacteria/germs in households, etc. Ethanol alcohol is generated from the cellulose and hemicellulose material present in the plant leaves by fermentation. Pretreatment of organic material with Urea or ammonia present (2 to 2.5% by wt) in the cattle or human urine, degenerates the fibrous lignin material present in the organic matter and facilitates the fermentation yeast to access/consume the cellulose and hemicellulose content in the plant-based organic matter. This pretreatment process is called slow Ammonia Fibre explosion. Generally, ethanol alcohol is produced from grains/fruits which are rich in starch/sucrose by yeast fermentation. With urine/ammonia pretreatment, cellulose and hemicellulose can also be converted into useful alcohols (ethanol and methanol) which can be used in pest control, disinfectants and for use as automobile fuel by blending with petrol after separating pure alcohol from fermented brew. Producing alcohol/biofuels from cellulose and hemicellulose is called second-generation biofuels. The alcohol content of the biopesticide can be enhanced by freezing the liquid, the solidified ice is removed and the remaining liquid is stored in sealed containers for a longer duration. The frozen ice can be used for room cooling. Preparation Any fresh leaves (preferably tender succulent plants, leaves, and shoots) are crushed into a paste and fresh urine is added in a 1:3 ratio (leaves:urine by weight). Urine with biomass is allowed to react slowly for 2 days until the active bubbling ceases. Wood-decay fungus is also added to the extent locally available to enhance alcohol yield. The treated urine with biomass loses its pungent smell as ammonia is absorbed by the biomass. Prepared baker's yeast preferably recombinant bakers yeast culture, by soaking dry yeast (1 to 2 gms) in sugar/jaggery mixed in water (100 ml for 10 liters of bio-pesticide) earlier, is added to the organic mixture. The mixture is allowed to ferment for two weeks duration and the solid sludge is separated and
